‘Fat and frail’ seniors benefit from right exercise combo – KSNT News

Posted: May 19, 2017 at 11:44 am

CHICAGO (AP) Heavy seniors who want to lose pounds safely shouldnt skip the weight machines or the treadmill, new research suggests.

Experts have worried about recommending weight loss to older, obese people because it speeds up bone and muscle loss, increasing the danger of falls and broken bones. Losing weight plus aerobic activity and strength training improved their health more than dieting plus either type of exercise alone.

The results suggest a combination of exercises is the safest approach, and may have big implications for helping people continue to live independently as they age. Medicare, the U.S. health insurance program for people 65 and older, now covers behavioral therapy for weight loss and some plans offer gym memberships.

It is the worst of both worlds, being fat and frail, said Dr. Dennis T. Villareal of Baylor College of Medicine in Houston, who led the study under a grant from the National Institute on Aging.

More than a third of Americans ages 65 and older are obese. Obesity can make the elderly vulnerable to medical problems, but losing weight can worsen frailty by hastening muscle and bone loss.

The study, published Wednesday by the New England Journal of Medicine, involved 141 older obese people who were randomly assigned to a diet-and-exercise program. They scored in the frail range on a standard test used with seniors.

One group did aerobics such as treadmill walking. Another did strength training with weight machines. A third group did aerobics and strength training. All exercised three times a week.

A control group didnt diet or exercise and only attended monthly nutrition classes.

After six months, all the groups except the do-nothing group had lost weight, about 19 pounds on average.

The combination and aerobics-only groups built their ability to use oxygen most efficiently, which can increase endurance. The combination and strength-only groups preserved the most lean mass and bone.

The health differences showed up in follow-up testing where participants did a series of nine tasks including picking up a penny, standing up from a chair and climbing stairs.

Most improved was the combination group with a 21 percent average increase in scores compared to 14 percent improvement in the aerobics-only and strength-only groups.

Its never too late to change lifelong unhealthy habits, Villareal said.

Minor injuries such as knee pain and shoulder pain among the exercisers were not enough to outweigh the benefits, he said.

The study excluded people with severe heart disease and other serious health problems, so the results apply only to people well enough to start an exercise program.

You get more bang for your buck with doing both types of training, especially when it comes to improving frailty scores, said Dr. Lawrence Appel of Johns Hopkins University, who was not involved in the study.

Diet Doc’s Fullness Factor Appetite Suppressant is Helping Dieters Stay on Track – Marketwired (press release)

Posted: May 19, 2017 at 11:44 am

LEXINGTON, KY--(Marketwired - May 19, 2017) - Many people struggle to manage their diet program. Whether it's a plant-based diet, ketogenic diet, military diet, consuming fewer calories long enough to see weight loss results can be challenging. After all, hunger and subsequent over-eating sabotages the majority of diet attempts. The in-house team of doctors at the nationally recognized medical weight loss center, Diet Doc have developed Fullness Factor -- a new appetite suppressant to satiate hunger and accompany most diet plans to accelerate weight loss.

Fullness Factor works to reduce hunger in-between meals to keep your diet program on track. These hunger suppressant pills combine the water-soluble fiber called glucomannan, which expands in the digestive tract and replicates the sensation of fullness, with a patented vegetable protein called Slendesta, a powerful appetite suppressant made from potato extract that sends the signal to your brain that you are full.

Fullness Factor should be taken an hour prior to each meal. The result? Eating less during meals, feeling full for longer periods of time, and seeing weight loss results without suffering through constant food cravings, mood swings and irritability that normally comes with a sudden reduction in calories. In fact, Diet Doc patients have noticed that Fullness Factor helps make a reduced calorie diet much more bearable. Diet Doc patients taking Fullness Factor have also observed other improvements such as reduced constipation, reduced cholesterol, and lowered blood sugar.

Each ingredient in this appetite suppressant helps to boost your weight loss results and achieve your goals safely and consistently. It is safe for long-term use and contains no harmful ingredients, stimulants, or caffeine. New Diet Doc patients can call or easily and effortlessly visit https://www.dietdoc.com to complete an initial comprehensive, yet simple, health questionnaire and schedule an immediate personal, no-cost consultation. Diet Doc Physicians all received specialized training in nutritional science and fast weight loss. Diet Doc reviews each patient's health history to create a personalized diet plan geared for fast weight loss, or that addresses life-long issues causing weight loss to slow down or stop. Nutritionists work personally with each patient and use their own algorithm to craft meal and snack plans that are compatible with each patient's age, gender, activity level, food preferences, nutritional needs and medical conditions. They combine these state of the art diet plans with pure, prescription diet products that enable their patients to resist the temptation to reach for sugary snacks, eliminate fatigue and curb the appetite. Over 97% of Diet Doc patients report incredible weight loss results with the majority losing 20 or more pounds per month.

At Diet Doc, all patients gain unlimited access to the best minds in the business. Their staff of doctors, nurses, nutritionists and coaches are available 6 days per week to answer questions, offer suggestions, address concerns and lend their professional guidance and support.

Swallowable balloon can help people with obesity to shed weight – Irish Examiner

Posted: May 19, 2017 at 11:44 am

A swallowable balloon can lead to a dramatic weight loss over months but is only a temporary solution for obese patients, a medical expert warns.

A study found that obese people lost around 2st 6lb (15kg) over 16 weeks when they used the balloon that makes people feel full.

The Elipse Balloon, which costs under 4,000, is available privately in Ireland. It is in a capsule that is swallowed with a drink of water.

The capsule is attached to a hollow plastic tube, and when the doctor checks that it is correctly in place, it is filled up with water. The tube is then detached and removed. After 16 weeks a valve disintegrates, and the device is excreted safely by the body.

In a study presented at the European Congress on Obesity in Porto, Portugal, the balloon was given to 42 obese people (29 men and 13 women).

They were typically aged 46; had a body mass index of 39; and weighed just over 17st on average. After 16 weeks people lost more than 14% of their total body weight, or around a third of their excess weight.

Work was also carried out with patients on changing their eating habits.

Study leader, Roberta Ineca from the University of Rome, said the patients were very happy with the results: During my daily phone contacts with my patients, they shared with me their pictures and the amount of weight they lost.

Dr Roberta Ienca, with a swallowable balloon which makes people feel full.

However, board member of the Irish Society for Clinical Nutrition and Metabolism, Professor Carel le Roux, said the balloon is not a treatment for obesity.

Prof le Roux works at the Diabetes Complications Research Centre at University College Dublins Conway Institute. He said obesity is a chronic disease: We now understand that obesity is a disease of the middle part of the brain the part that makes you feel more hungry or makes you feel very satisfied.

Prof le Roux, who treats people with obesity-related diseases, said, he would recommend the balloon, of which there are various types, for short-term weight loss: If we want people who are too sick to have an operation, such as a gastric bypass, heart or knee operation we can use the balloon to get them to a safe weight in three or six months time.

However, he does not think the balloon would be available under the public health system in Ireland in the future because the health economic benefit is very poor.

Prof le Roux said he has not used the capsule-type balloons that are available in Ireland because other balloons that are inserted into the stomach via the gullet using an endoscope are cheaper and achieve the same result.

People with obesity needed to know the balloon is not a treatment for obesity and that they will most likely regain all the weight they lost when the balloon comes out, he said: It is not a treatment for obesity, but it is a treatment for acute weight loss that will be followed by weight gain.

Yvonne Culleton: Keeping a Food Diary in the battle for weight loss – Leinster Express

Posted: May 19, 2017 at 11:43 am

No 1- Food diary

Nowadays there are so many quick fixes and fad diets, which yes will help you lose weight but will you maintain it???

90% of the time the answer is NO! See if we lose a lot of weight quickly we lose some very important and essential lean tissue (muscle), which controls our metabolic rate (rate in which we burn calories). Weight regained after the diet could be fat tissue which is a lot lazier. For every 1lb of lean tissue we burn 50 calories at rest but for every 1lb of fat we only burn 4 calories. So it is pretty lazy!!

Even if you dont over-eat you could regain weight anyway because of the greater the proportion of lazy fat tissue in your body, because your metabolism is slowed and because lost fluid will replace itself.

The only way to maintain weight loss and adapt and keep a healthy lifestyle is a slow and steady weight loss, and take baby step with changing things in your diet, a drastic exclusion of too many things will deffo set you up for failure.

Realistically we can only lose about 1-2lb of actual fat per week, the rest is fluid. Maybe the first few weeks if you have a lot to lose you might lose more but that will stabilise after a few weeks.

A very useful tool if your goal is weight loss would be to record a food diary. Maybe 5-7 days and just have a sheet of paper with you, it doesnt have to be anything fancy!

Record everything from water consumption, a lot of uncounted calories can be consumed in liquid form so record all drinks, if you have sugar in your teas/coffees, portion size of each meal and snack, how you are feeling if you reach for that sugary treat. Some people dont realize it but our emotions play a lot in our eating habits.

If we are feeling tired or down or had a bad day we tend to reach for sugary things kind of like a reward to cheer yourself up, so just put a little note on it of how you were feeling and see if there is a pattern there.

Times in which we are eating at which is also very important .. We all know how important having our breakfast is dont we? Its so very very important.

Metabolism needs to be kicked right in the butt first thing It slows down as the day goes on and by evening/night it can be very slow so eating huge portions and junk food at them times will just store as unwanted fat. So put times on your diary too.

Then when the 5-7 days are up have a read through it yourself and check for things like, did I have breakfast today?, did I snack in between meals, have I drink enough water? Have I had too much sugar in my tea/coffee (if you put the same quantity of sugar you usually put in tea/coffee into a container and at the end of the week see how full that container is or add up the tea spoons, will you be shocked??)

FYI: As an adult our recommended allowance of added sugar PER DAY IS 5 TEA SPOONS. So do the math and see how you go.

Am I getting enough of all food groups? ( fruits, meats, veggies, dairy, grains), is my diet varied?, am I following my metabolism, ie. eating a well-balanced breakfast, mid-morning snack, well balanced lunch, mid afternoon snack, and dinner. Little and often is key. This well help stabilize blood sugar levels and prevent sugar impulses.

Am I drinking enough H20?! People can suffer from mild dehydration and not even know it, if you drink a lot of tea/coffee you are at risk of mild dehydration as tea/coffee are diuretics. What this means is they can make you want to wee a lot which so you will lose a lot of fluid that needs to be replaced, so youll feel thirsty again and probably reach for more tea/coffee and then it will just do a full circle!

Your energy levels will drop also and if you train your muscles could cramp due to lack of hydration. A little tip on how to work out your recommended water intake would be to multiply your weight in kg by 0.033. This would have to be increased with activity level.

Also IF ITS NOT IN IT WONT GO IN! Everyone knows if the bad stuff isnt in the presses you cant put them in your mouth!!! So dont buy them in your weekly shopping. Simples!

Continued recording of a food diary will help you maintain your healthy lifestyle.

Give it a try and see how you get on. And be completely honest with everything youll be codding none but yourself if you dont!!!

Good luck.

If any of ye reading this would like to email me your food diary to ytynan@live.com or PM my page LOL Ladies Only Lifting on Facebook Ill give you some feedback on it..

Next week I will talk about our BMR (Basal Metabolic Rate), a very effective tool in fat loss.

Thank you for reading..

‘Pill’ which inflates after swallowing helps slimmers shed third of their weight in four months – Devon Live

Posted: May 19, 2017 at 11:43 am

We've all seen the adverts for magical quick-fix solutions to losing weight quickly but now scientists may have developed a 'magic bullet' for slimmers.

All you need to do is swallow a pill. The pill is actually a hi-tech gastric balloon which inflates after you swallow it. Once it's in your stomach, it inflates and fills up your stomach to make you feel full and then deflates itself after four months,according to Mirror Online.

Details of the brand new slimming aid were presented at the world's biggest obesity conference in Porto, Portugal this week.

Trial results found the 15-minute balloon operation was 'safe and effective' and triggered 'substantial weight loss' in obese patients.

On average, those who use the treatment shed a third of their excess body weight. Patients aged between 27 and 67 each lost an average of 15.2kg (2st 4lbs).

It has already been approved for use in the UK and could help those who find it impossible to shed the pounds through normal diets. Experts said that millions of Brits could eventually benefit from the simple pill. Unlike existing gastric products, no surgery is required to insert or remove it.

Dr Roberta Ienca, of Sapienza University of Rome, who led the study, said: "Because the Elipse Balloon does not require endoscopy, surgery or anaesthesia, this may make it suitable for a larger population of obese patients not responding to diet or lifestyle treatment."

Dr Ienca told the Daily Mirror that all the patients also enjoyed "improvements in overall metabolic health including blood pressure, cholesterol levels, and blood sugar control".

She described the reaction of patients to the device as "incredible".

She said: "They are very happy about the results they were able to achieve.

"During my daily phone contacts with my patients, they shared with me their pictures and the amount of weight they lost.

"They are very satisfied with the results achieved day after day."

Speaking at the the European Congress on Obesity in Porto, Portugal, Dr Ienca added that it could also be fitted in patients "by a variety of clinicians - nutritionists, dietitians, and internists - who currently do not have access to or are qualified to fit endoscopic or surgical weight loss devices."

The patient swallows a tiny pill containing the deflated Elipse balloon, which is made from a delicate polymer film.

A catheter is attached and once the pill has reached the stomach, a doctor fills the balloon with 550ml of water through the catheter, then tugs on the tube to detach it.

The filled balloon takes up a large part of the stomach, reducing appetite and improving the patient's odds of shedding weight.

And after 16 weeks, a valve in the polymer film opens and the balloon collapses. It passes out normally through the digestive system.

Previously, most existing gastric balloons rely on a surgeon putting the device in the stomach using an internal probe while the patient is sedated or under anaesthetic.

It also has to be removed during surgery the same way.

Two in three Brits are overweight or obese.

It is not yet available on the NHS but is available through some private weight loss clinics in the UK.

The NHS is already trialling similar balloon pills to the one in the study presented in Porto.

The cost for the full treatment varies between 2,200 and 3,400 - less than half the cost of gastric band surgery.

The balloon pill has the potential to provide "significant cost savings" for the NHS and save billions of pounds a year.

Obesity now costs the NHS 16billion a year - which includes treating obesity-linked medical conditions like Type 2 diabetes.

The study presented in Porto found that the swallowable gastric balloon "is a safe and effective way to induce substantial weight loss".

Read next: Young driver who died in A38 crash has been named

The research examined the impact of the balloon on 50 obese patients who had failed to lose weight by diet alone and who had refused other gastric treatment, because of the need of an endoscopy or anaesthesia.

Each patient had the balloon in their stomach for 16 weeks after which it spontaneously opened, emptied, and was excreted. They were checked every two weeks.

In the last four weeks of the treatment, a very low calorie diet of 700 kcal/day was introduced to enhance weight loss and maximise the results to increase patient satisfaction. Once the balloon was excreted, patients were transitioned to a Mediterranean diet for weight maintenance.

After 16 weeks, the average weight loss was 15.2kg. The average percentage weight loss was a drastic 31 per cent.

There were no serious adverse events recorded. All other adverse events including nausea, vomiting, and abdominal pain were either self-limiting or resolved with medication.Dr Ienca concluded: "The Elipse Balloon appears to be a safe and effective weight loss method. Furthermore, the absence of endoscopy and anaesthesia for placement and removal can lead to significant cost savings."

Prof Jason Halford, treasurer of the European Association for the Study of Obesity, which is hosting the world's biggest obesity conference, said: "With bariatric surgery, there are potential complications, it's a very permanent change in your life and it's not easily reversible.

Read next: Boat on the road blocks M5 in Exeter

"People are looking for alternatives. "I think this is for people before they would get to the point where they need bariatric surgery. Potentially millions could benefit

"I think if studies are there and it's cost-effective... I think it should be considered on the NHS."

Dr Simon Cork, Research Fellow at the Department of Investigative Medicine, Imperial College London, added: "Currently, gastric balloons have to be inserted under general anaesthetic or sedation.

"This not only limits the number of patients who can have them implanted, but also increases surgery time and has significant costs associated with it."

He added: "The introduction of a device which doesn't require surgery to implant is a positive step forward."

Room packed for inquest into death of David Cauldwell who was found in Torquay woods

Feelings ran high when friends and family packed into the coroner's court in Torquay on Thursday for the inquest into the death of 39-year-old David Cauldwell. The inquest heard that Mr Cauldwell, a self-employed building contractor who lived in Thurlow Road, Torquay, was found dead at the bottom of a steep wooded area at Petitor, Torquay, on May 25 last year three days after he had been reported as missing. An extensive search by police, partner agencies and Mr Cauldwell's friends was carried out, which resulted in two bodies being found just 200 metres apart, although the deaths were not connected.

Mann: Diets don’t work, instead think smart strategies for weight loss – Brainerd Dispatch

Posted: May 18, 2017 at 2:45 pm

Traci Mann is the keynote speaker at the free Crow Wing Energized Health and Wellness Summit Friday in Baxter. The summit is set from 7 a.m. to 1 p.m. Friday at Lakewood Evangelical Free Church, 6284 Fairview Road in Baxter. There are still seats available for the fourth annual health and wellness summit, which also provides a free continental breakfast and lunch.

Mann is a professor of psychology at the University of Minnesota. She has a doctorate in psychology from Stanford University and was a professor at UCLA before moving to Minnesota. Mann founded the Health and Eating Lab. Her biography notes her research has been used by the National Institutes of Health, the U.S. Department of Agriculture and NASA.

In her book "Secrets from the Eating Lab," Mann looks at a number of questions.

Is it my fault if my diet didn't work?

If I don't diet won't I gain a lot of weight?

Do I have less willpower than everyone else?

What is a reasonable goal weight?

Can I be healthy if I don't lose weight?

What are smart regulation strategies?

"Because diets don't work. And you don't need them to work, because you can be happy and healthy without dieting. Instead, we offer 12 smart regulation strategies that help you reach and maintain your leanest livable weightthe weight at the low end of your set range," Mann states on her website for the book. "These scientifically tested strategies work because they don't fight biology or rely on willpower. They don't require agonizing self-denial or a single-minded focus on your weight, so you can make these simple changes and then get on with the important things in life."

In addition to Mann's presentation, participants at the summit will hear from local success stories from those who took part in Crow Wing Energized lifestyle change classes. There will also be an opportunity to experience two of the nine breakout sessions:

Promoting health and movement in the workplace,

Why Zoe Saldana doesn’t believe in diets – ABC News

Posted: May 18, 2017 at 2:45 pm

Zoe Saldana has given up on dieting.

"I try not to deprive my body of anything because the moment I have just salads and protein for a few days, I crave carbs. But when I eat everything in balance, I think less about food and more about everything else. Its about eating to live, not living to eat," the 38-year-old actress told the June issue of Shape.

The "Guardians of the Galaxy" star focuses instead on eating clean.

"Its not that I like to eat superlight, just superclean. I like food that is fresh," she said. "I dont go for things that come in a can -- and Im losing trust in things that come in plastic."

She and her husband, Italian artist Marco Perego, like to prepare their own meals, choosing to eat more vegetables and less meat.

"My husband and I have been learning to cook with Asian spices, like turmeric, and ginger, and were having a blast," she said.

Diagnosed with Hashimotos thyroiditis in 2012, Saldana is motivated to eat clean in order to stay healthy.

"I know Ive become a very boring person to take to dinner, but Id rather be that way than deal with health issues," said the actress, who is gluten- and dairy-free, just like the rest of the family. "When you have an autoimmune condition, you have to stay away from foods that cause inflammation."

The busy mom of three boys -- twins Cy and Bowie, 2, and Zen, who she welcomed in February -- doesn't always have time to exercise either.

"I cant work out regularly, so I compensate by eating a lot healthier than I might otherwise," she said. "Once you have relatively healthy eating habits, your workout can become playing with your kids, strolling around the neighborhood, playing airplane, or just changing diapers."

After the birth of her twins, Saldana opened about the physical challenges of getting back into shape. Not only did the actress gain 70 pounds, but Saldana explained on Facebook that "everything from my thyroid to my platelets crashed" after giving birth.

Diet not working? Maybe it’s not your type – Harvard Health (blog)

Have you heard of the blood type diet? I thought it had been debunked long ago but patients keep asking about it, so I figured I should learn more.

In 1996 Peter DAdamo, a naturopathic physician, published a book in which he described how people could be healthier, live longer, and achieve their ideal weight by eating according to their blood type. Ones choice of condiments, spices, and even exercise should depend on ones blood type. Soon, the book was a best seller and people everywhere were finding out their blood type, revising their grocery lists, and changing how they ate, exercised, and thought about their health.

Here are some of the recommendations according to the Eat Right for Your Type diet:

As mentioned, the recommendations for the blood type diets extend well beyond food choices. For example, people with type O blood are advised to choose high-intensity aerobic exercise and take supplements for their sensitive stomachs, while those with type A blood should choose low-intensity activities and include meditation as part of their routine.

High-quality studies about the blood type diet had not been published in peer-reviewed medical literature. Even now, a search in the medical literature for the authors name reveals no research pertaining to this diet. Studies published in 2013 and 2014 about the blood type diets are worth noting. The 2013 study analyzed the worlds medical literature and found no studies demonstrating benefit from a blood type diet. The 2014 study found that while people following any of the blood type diets had some improvement in certain cardiometabolic risk factors (such as cholesterol or blood pressure), those improvements were unrelated to blood type.

The theory behind this diet is that blood type is closely tied to our ability to digest certain types of foods, so that the proper diet will improve digestion, help maintain ideal body weight, increase energy levels, and prevent disease, including cancer and cardiovascular disease.

Type O was said to be the original ancestral blood type of the earliest humans who were hunter-gatherers, with diets that were high in animal protein. Group A was said to evolve when humans began to farm and had more vegetarian diets. Group B blood types were said to arise among nomadic tribes who consumed a lot of dairy products. And since Group AB blood was supposed to have evolved from the intermingling of people with types A and B blood, type AB recommendations were intermediate between those for people with types A and B blood.

Each of these theories has been challenged. For example, there is evidence that type A was actually the first blood group to evolve in humans, not type O. In addition, there is no proven connection between blood type and digestion. So, in addition to a lack of evidence that the diet works, serious questions remain about why it should work in the first place.

Its a fair question, especially since some improvements were seen in people who adopted certain blood type diets (see link above). Eating based on your blood type requires you to know your blood type and then follow a restrictive diet. Personal preferences might be a problem: a vegetarian with type O blood may struggle to stay on the assigned diet, and people who love red meat may be disappointed to learn they have type A blood. Recommended supplements are not cheap; neither are the recommended organic foods. And if you have certain health conditions, such as high cholesterol or diabetes, a nutritionist can make better evidence-based recommendations for you than those determined by your blood type.

Advocates of blood type diets may say that while the ideal study has not yet been performed, the absence of evidence doesnt prove theyre ineffective. And theres also no proof that these diets are harmful. So, my guess is that interest in the blood type diets will not disappear any time soon. But theres a reason that bookstores have rows and rows of books on diet, each claiming to be highly effective if not the best. We simply dont know which diet is best for each individual person. And even if we did, sticking to any single diet is often challenging.

Stand by its likely youll soon be hearing about yet another best diet. And my guess is that it wont have anything to do with your blood type.

Some mycotoxin mitigations may be less effective in fishfeed – FeedNavigator.com

Posted: May 18, 2017 at 2:45 pm

Some types of feed additives developed to mitigate mycotoxins in feed for warm-blooded animals may be ineffective for fish, says new research.

A team of researchers at the University of Guelphs fish nutrition research laboratory examined the use of one type of commercially available feed additives to mitigate the mycotoxin deoxynivalenol (DON) in the diets of rainbow trout(oncorhynchus mykiss). The group published its research in the journal Aquaculture .

The objective of this study was, therefore, to investigate the potential efficacy of a commercial feed additive (CFA) with adsorbing and bio-transforming properties in minimizing or preventing the adverse effects of diets naturally contaminated with DON on growth performance and nutrient utilization of rainbow trout, said the researchers.

The team found that use of an absorbing and bio-transforming commercially available mitigation product in trout diets did not improve fish performance.

The feed additive used here was developed through extensive research and development with homeotherms; therefore, use in feeds for cold water fish species may be outside the scope of its effectiveness, they said. Additional work is essential to systematically develop novel approaches for mycotoxin mitigation in highly sensitive farmed fish species.

Mycotoxins are a group of naturally occurring metabolites generated by some fungi and that produce negative effects in human and animals when consumed, said the researchers. Mycotoxin contamination stems from fungal infection of feed crops and is linked to environmental conditions during different stages of production and storage.

In general, mycotoxins are not removed during a routine feed manufacturing progress, they said. The contaminants are often linked to unspecific symptoms ranging from reduced production to mortality, and sensitivity to mycotoxins tend to vary based on several factors including animal species and age.

It has been estimated that 25% of the world's crop production is contaminated with mycotoxins, said the researchers. The economic impact of mycotoxins is effectively impossible to quantify; however, risk assessment analyses have estimated that financial losses to US agriculture associated with crop losses, mitigation efforts and reduced livestock performance or mortality range from $630m to $2.5bn per annum.

Mycotoxins often considered in relation to animal health include aflatoxins, ochratoxins, fumonisins, zearalenone (ZON), they said. The group also includes a set of compounds called the trichothecenes, which includes deoxynivalenol.

The expanding use of plant-based ingredients in aqua feeds has increased the potential for farmed fish to face mycotoxin exposures, they said. In a survey of carp feeds, 80% of samples were found to have detectable amounts of DON.

Chronic feed-borne exposure to low doses of DON is commonly associated with anorexia (reduced feed intake and growth), decreased productivity and altered nutritional efficiency, said the researchers. Comparatively, acute, short-term exposure to higher concentrations of DON may result in leucocytosis, gastrointestinal hemorrhage, diarrhea and emesis or vomiting, particularly in pigs.

Several important finfish species are considered to be highly sensitive to DON, they said. The presence of the mycotoxins in trout feed has been linked to reduced weight gain, limited thermal-unit growth coefficient (TGC), limited feed intake and feed efficiency, along with reduction in carcass crude protein content, retained nitrogen, recovered energy, nitrogen retention efficiency and energy retention efficiency.

Feed additives are often used in feeds to mitigate the negative influence of mycotoxin presence, they said. Additives can be absorbing agents, like clay minerals or yeast cell wall extracts, or bio-transforming agents, such as bacteria, fungi, yeast and enzymes.

These products have been studied in several terrestrial, monogastric species, they said.

However, most of the work looking at mitigation products in fish feeds has examined the use of clay-based mineral products, they said. Little work has been done examining the use mycotoxin mitigation products that act through absorption or biotransformation.

In the study, 1,200 fish were given one of eight diets for a 12-week growth trial, said the researchers. The diets contained one of four levels of DON from naturally contaminated corn and were fed with or without the commercial feed additive (CFA).

Initial bodyweights were recorded and a sample of fish was collected to establish initial carcass composition, they said. During the study, feed intake was noted weekly and weights were taken every 28 days.

Fish were sampled at the end of the feeding trial to examine final carcass compositions, they said.

Diets, feed ingredients and fish tissues were checked for dry matter, ash, crude protein, lipids, gross energy content, they said. Growth rate, feed efficiency, retained nitrogen, recovered energy, nitrogen retention efficiency and energy retention efficiency were calculated.

Use of the CFA to mitigate the mycotoxin was not found to be effective, said the researchers. Mortality was not altered by the experimental diets.

Highly significant linear decreases in weight gain, feed intake and thermal-unit growth coefficient (TGC) were associated with increasing levels of DON in fish fed the diets with or without the CFA, they said.

Fish getting the contaminated feed showed loss of whole body crude protein, lipids, ash and gross energy content, they said. With increasing levels of DON in the feed, the fish also had increased water content and both linear and quadratic decreases in retained nitrogen, recovered energy, nitrogen retention efficiency and energy retention efficiency.

Inclusion of the CFA at the recommended rate (2 g/kg feed) did not minimize the adverse effects of diets containing increasing, graded levels of DON (up to 2.0 ppm) on growth performance, body composition or nutrient utilization of rainbow trout, said the researchers.

No significant interaction was noted between DON and the use of CFA in the fish diets, they said. Additional work is essential to systematically develop novel approaches for mycotoxin mitigation in highly sensitive farmed fish species, they added.
