(CNN) - A new study out of Harvard Medical School says higher good cholesterol levels may not lower heart attack risks.

It says genetic tests haven't shown a link between higher HDL and a lower risk.

HDL is the so-called "good" cholesterol.

One of the study's authors tells Web MD that HDL is important tool for figuring out heart attack risk.

But, he says this research raises questions as to whether there are benefits to taking drugs to increase those levels.

Studies have shown that high LDL or bad cholesterol, is linked to an increased risk of heart attacks.

So the takeaway message from doctors, is to definitely lower your LDL.

The study is published in the journal Lancet.

Study: “Good Cholesterol” may not be that good for you

FA=high-fat, ab libitum (eat-at-will) diet, FT=high-fat, time-restricted diet, NA=normal ab libitum (eat-at-will)diet, NT=normal diet, time-restricted

Diets tell youwhat you eat, but a new study suggestswhen you eat matters too. Of two groups of mice who were fed the same high-fat diet, themice who could eat around the clock were much heavierthan those who had food restricted to eight hours per day, in a new study published inCell Metabolism.

Researchers in the study gave the mice a special high-fat chow, 61% of whose calories come from fat (compared to just 13% in normal feed). The mice who chowed down all day and night became, unsurprisingly, obese, but the ones who ate the same amount of hi-fat foodin only eight hours per day did not. Their body weight was comparable to mice fed an equivalent amount of calories on normal feed.

This being a study inCell Metabolism, the researchers didnt stop with just weighing the mice; they did a lot of molecular experiments to work out the link between timing and weight gain. Mice on high-fat, eat-whenever diets had the insulin problems associated with obesity-induced diabetes and lower expression of genes linked to breaking down fats in the liver, leading to fat accumulating in the liver. The high-fat, time-restricted diets did not have those problems.

This might make sense in light of ourcircadian rhythms, which are the approximately 24-hour cycles that govern sleep as well as metabolic functions such when the liver secretes bile and the pancreas insulin.Previous researchhas found that sleep-deprivedand jetlagged people, whose circadian rhythms are out of whack, are at risk for weight gain. The current study adds to the link between circadian rhythms and weight, suggesting that eating fat at odd hours disrupts daily metabolic cycles.

CASES of stroke have become increasingly common. Stressful lifestyles, lack of exercise and diets have been blamed. Is this justified?

Last year, a journal reported that among the 192 World Health Organisation member countries, deaths from stroke exceeded those attributed to heart disease in 74 of them.

Disability arising from stroke also exceeded heart disease fatalities in 62 countries accounting for 32 per cent of member nations. It was, however, reported that stroke was higher in Asia, Africa and South America, whereas heart disease was higher in the Middle East, North America, Australia and much of Europe.

Malaysia is among countries in Asia which have been reporting a rising incidence of stroke cases. The situation has reached worrying levels. The cost to the country is enormous. Can neuroscience help? But what is neuroscience?

Neuroscience refers to the science involving the central and peripheral nervous system. This mainly concerns the brain and spinal cord plus the outlying nerves of the body. If in the past neuroscience was just an offshoot of the medical discipline, nowadays this is no longer true.

As technology improves over the last 20 years, the subject has evolved into a transdisciplinary sciences from its classical multidisciplinary roots.

Neuroscience now incorporates elements of computer science, physics, mathematics, chemistry and even music and economics.

Recent years have seen rising interest in neuroscience. This is especially so in the more developed nations where many have realised the importance of research in neuroscience as a way to look for answers as to how to prevent, treat or rehabilitate stroke patients.

So much so that, among medical practitioners, neuroscience has been hailed as the fifth revolution in science after astronomy, evolution, psychology and the discovery of the DNA.

The unprecedented scientific advances over the last decade have led to the widespread view that the world is on the verge of a neuroscience revolution. And this will dominate scientific endeavours in the next two centuries.

We all feel the same way about weeds: We don't want them in our garden. But Joseph Leyda, a certified ecologist and permaculture designer in Vancouver, wants you to look beyond the nuisance. The best way to deal with a garden full of weeds is to pluck them from the ground -- and put them on your plate.

Leyda will hold an Edible Weed Workshop on Sunday at the 78th St. Heritage Farm at Washington State University's Clark County Extension Offices, where he will show participants how to identify weeds in your own backyard and how to harvest and add them to your diet.

Leyda molded one-quarter of an acre of the farm into a forest ecosystem last December, layering trees, shrubs and herbs on top of one another into what's called a guild.

"Weeds can occasionally perform positive functions," Leyda said. "When guilds mature and the intended plants become established, a few weeds can actually help the system."

The workshop will close with a tour of the grounds, allowing attendees to identify, harvest and eat the weeds they find. To register, go to the extension website and click events.

"We want people to come away with the idea of looking at weeds as resources instead of the enemy," said Jenifer Naas, program coordinator and lead watershed steward at the 78th St. Heritage Farm.

Here are a few weeds Leyda recommends picking up and adding to your diet this spring:

Pierre Dukan asked to be removed from the doctors list because he was facing disciplinary action He proposed giving teenage school pupils extra exam marks if they kept to ideal weights

Controversial: Nutritionist Pierre Dukan has been struck off as a doctor in France after he was accused of giving dangerous advice to teenagers

A diet guru whose fans include the Duchess of Cambridge's mother has been struck off the medical register in France after being accused of misadvising teenagers.

Pierre Dukan, 70, asked to be removed from the doctors list at his own request because he was facing disciplinary action.

The nutritionist had used a book to propose ideal weights for 17 and 18 year-old school pupils, giving them extra exam marks if they kept to them.

It led to a formal complaint from the College of Physicians in Paris, who said that the scheme could lead to increased cases of obesity and anorexia.

The physicians said Dukans proposal was in breach of article 13 of the medical ethics code which states: A doctor must be aware of the repercussions his views can have on the public.

There was also an allegation that Dukans 80 million plus slimming business might be in breach of medical codes.

SAN FRANCISCO (CBS 5) Converts to the trending paleolithic diet say the eating habits of our caveman ancestors, along with exercising and getting enough sleep, will keep your body running smoothly well into your golden years.

This is a diet that would be good for anybody, said UCSF nephrologist Dr. Lynda Frassetto, who has been studying the paleo diet for years.

CBS 5 HealthWatch Series On Paleo Diet

A key factor, according to Frassetto, is limiting the level of acid in the body. Acids, which are regulated by the kidneys, tend to build up as people grow older and their kidneys work less well.

But paleo proponents believe that the right diet can bring acids back into balance. Specifically, this means eating more fruits and vegetables, the so-called base foods, and eating fewer animal proteins and grains, which are high-acid foods.

When you look at things like what do hunter-gatherers and chimpanzees eat, you get a diet that has meat in it, and a lot of fruits and vegetables, and no dairy products and no grains, explained Frassetto.

There is also some evidence that a healthy diet, along with exercise and stress reduction, can help protect a key ingredient in the aging process called telomeres.

Telomeres are the protective caps on the ends of the chromosomes, explained Dr Elizabeth Blackburn, a 2009 Nobel Laureate. If the caps are eroded away, the cells will stop replenishing.

But it turns out that telomeres are dynamic they can change, and the choices people make can affect that change.

7-Eleven

Fanta Mango is the first flavor of Lite Slurpee. Next up: Strawberry Banana and Cherry Lemonade.

By Rob Neill

It probably says something more about America than it does about 7-Eleven, but starting this month the retailer is rolling out a product that seems right for its time: a sugar-free Slurpee.

Fanta Sugar-Free Mango is this months diet flavor. 7-Eleven said it has spent two years coming up with the formula for a simple reason: customer demand.

For years weve gotten calls through our guest relations hot line, When are you going to have a diet Slurpee? company spokeswoman Margaret Chabris said. The calls have come not only from the weight-conscious but from diabetics and those with other nutritional issues, she said.

We worked at that formula for two years, trying to nail the right attributes of the Slurpee. Not just the taste. But you need to have Slurpee all the way to the bottom of the cup, not just water and ice.

Cost will be the same as a standard Slurpee. Formulas may differ, but for example the Fanta Wild Cherry is 66 calories for 8 ounces. The diet equivalent is 20 calories. It will be available at all participating 6,700 7-Elevens in the U.S.

It'sunknown how many people, if any,drink Slurpees in 8-ounce servings. According to 7-Eleven literature, each year Americans drink enough Slurpees to fill 44 Olympic-sized swimming pools

It also makes business sense to try something new.Americans are drinking fewer soft drinks -- although its still about two a day for each person.
