Seven nutrition myths busted including why snacking isn’t bad for you – Fit and Well

Posted: August 9, 2022 at 2:11 am

Many people will have grown up hearing and believing various nutrition myths. From old wives tales to fad diets, its difficult to know what to believe when it comes to health and nutrition. This is particularly true when new research is often being undertaken and its not unusual for experts to change their mind about the best foods to eat for good health.

But there are some long standing myths about nutrition that simply arent true, even though lots of people might have believed them for a long time (and adjusted their diets accordingly as a result). One of the reasons is that a lot of people are looking for quick fixes when it comes to losing weight, gaining muscle or improving their overall health. But doing any one of these things is rarely simple and it often requires making a number of different changes to your diet, such as using the best protein protein powders for weight loss or supplementing where there are shortfalls in particular nutrients.

So what are some common beliefs we have about nutrition that are actually completely unfounded? We asked Sophie Medlin, a dietician at CityDieticians (opens in new tab), to debunk seven nutrition myths that you might have otherwise believed.

Youll often find gluten-free products in the health section of a supermarket, which might make you think theyre healthier alternatives to food items with gluten in, like pasta and bread. But actually, theres nothing wrong with eating gluten for most people.

Gluten causes no harm unless you have coeliac disease or an intolerance, Medlin says.

If you think you have a gluten intolerance, its best to speak to your doctor so you can take the relevant tests and opt for a gluten-free diet. However, for most of the population, gluten-free pastas and breads actually arent the best choice.

The vast majority of gluten free foods contain extra, fat, sugar, salt and other additives to make them taste better, meaning theyre worse for your health, Medlin explains.

Fat is one of three macronutrients, alongside carbohydrate and protein, meaning its an essential part of a healthy, balanced diet. However, fat has been villainised over the years and many people consider all fatty foods unhealthy.

Yet there are actually a lot of healthy fats that you can find in foods like avocados, peanut butter and oily fish. Omega-3 foods are also part of a healthy diet.

According to Medlin, there are some cases when low-fat foods could be beneficial, like if you have high cholesterol. Often, whether or not a low-fat product is better for you will also vary on a case by case basis. For example, semi-skimmed milk is generally better than full cream, Medlin says. In general though, when the fat is taken out of a product, it is usually replaced by sugar or artificial ingredients, meaning you are less likely to benefit from the lower fat content.

Ever followed a diet that told you to cut out snacking completely? This could have inadvertently been working against you. Snacking can be a really useful way to regulate your appetite throughout the day and prevent overeating, Medlin says.

A 2014 study (opens in new tab) found that whether or not snacking is beneficial for your health will depend on a number of things including your age and your attitude towards snacking, suggesting: developing recommendations regarding snacking and meal frequency is extremely problematic for numerous reasons.

Its never healthy to feel hungry and low in energy and often snacking is the best solution for this, particularly if you have an active lifestyle. I have to add planned snacks to most of my patients' diets to ensure they dont graze all afternoon or eat too much in the evening, Medlin adds.

Weve all heard the phrase that breakfast is the most important meal of the day. But is this really true?

We used to think that skipping breakfast was a bad idea but now we know that eating to your appetite is better, Medlin says. If you dont feel hungry first thing, wait until you are hungry but make sure this doesnt mean that youre so hungry at lunch time that you eat three times as much as you would if you had breakfast.

A 2014 study carried out over four months actually found that eating breakfast didnt have any significant impact on weight loss compared to not eating breakfast. So its a good idea to listen to your body when it comes to food; this might mean having five small meals in the day, rather than three big ones, or it might involve skipping certain meals, like breakfast, if you have no appetite. Its all about figuring out what works for you.

As well as fats, many people believe carbohydrates are inherently unhealthy and that we should minimise the amount of carbs we include in our diet. But actually, carbohydrates are in almost every food we eat and focussing solely on this one macronutrient might mean you neglect other areas of your diet.

Medlin explains that for most people, eating a low carb diet will induce weight loss. But this doesnt mean it is right for everyone because any calorie controlled diet will induce weight loss even if its 90% carbohydrate, she says.

There have been various studies undertaken on the effectiveness of low-carb diets, with a recent study (opens in new tab) finding that low-carb diets can be effective in the short term for weight loss but are not necessarily healthy in the long term.

Medlin stresses that its important to also think about how following a low-carb diet could affect your attitude towards nutrition: For some people, restricting carbs can mean that all they think about is carbs and then they end up bingeing on them so it really doesnt work for everyone.

Most people would struggle to find anything enjoyable about a juice cleanse (i.e. fasting other than drinking a set number of juices for a certain time period). But many people try them in an attempt to lose weight or detox their body.

However, Medlin says that these types of cleanses are generally fruitless. Nothing can detox your body apart from your liver and your kidneys, she says. Juice diets actually put your kidneys under a lot of pressure with a number of people being hospitalised as a result.

Your liver and your kidneys need normal food to work optimally and juice diets restrict their ability to do their job properly and put them under additional pressure creating more toxins in the body rather than less.

And while juice cleanses might make you lose weight right away, a 2017 review (opens in new tab) found that they can actually lead to weight gain when you return to your regular diet.

Nutritional supplements have become increasingly popular in recent years, with 2021 data (opens in new tab) suggesting that 20 million people in the UK are taking supplements every day. Many people believe that taking daily vitamin and mineral supplements are an essential part of being healthy but this isnt necessarily true.

According to the NHS in the UK, most people do not need to take vitamin supplements and can get all the vitamins and minerals they need by eating a healthy, balanced diet. Plus, taking some supplements unnecessarily could be potentially dangerous, according to Medlin.

There is no one-size-fits-all when it comes to supplements and its really important to remember that supplements are not benign, she says. Vitamin and mineral supplements in particular can cause physical harm and potentially permanent health harm for people who have particular conditions or genetic traits.

This isnt to say that supplements are redundant they can be a really useful tool if youre lacking in specific vitamins or nutrients, especially if your doctor has recommended taking them to improve your health. But they are not an essential part of a healthy lifestyle for everyone.
