There are many food myths and stories around that prevent a great many people from enjoying the benefits of certain foods.

Is red meat bad for you? Is a cooked breakfast always unhealthy?

Most have origins that have been lost over time but some more modern myths and older myths are still doing the rounds.

Check out the following popular beliefs and challenge your assumptions.

It's best to eat fruit at the end of a meal ? ....

Fruit eaten after a meal will be broken down at a faster rate than the main components of the meal, and so can speed up the transition of foods into the colon.

While the meal itself is being broken down, the fruit may start to ferment, which can lead to bloating and wind.

True Food Myth - Fruit is better off eaten alone, away from your main meal.

A full English breakfast Can Never Be Healthy ? ....

False Food Myth - If you grill lean bacon, poach your eggs, include baked beans, grill your tomatoes and cook your mushrooms without fat, then serve it up with thick silce of crusty bread, you'll have yourself a delicious cooked breakfast that is also healthy and balanced.

You should never eat after 9pm ? ....

Its usually better to aim to have finished dinner about three hours before retiring for the night. Digestion can slow at the end of the day, so ideally your evening meal shouldn't be too large.

For those who get hungry after supper, or for people who suffer from insomnia, try a small snack last thing, such as a small piece of fruit and a few raw nuts.

Cottage cheese and bananas contain an amino acid known as Tryptophan, which can aid sleep, so perhaps have a little of each.

Red meat is bad for you ? ....

False Food Myth - Red meat contains valuable protein, yet many people who reduce their meat intake do not replace it with other protein rich foods. Meat is considered a 'complete' protein in as much as it contains the full range of amino acids, whereas pulses and beans are incomplete.

If you do reduce red meat, then ensure that you replace it with fish, poultry or tofu for complete protien intake.

Remember that red meat contains an absorbable form of iron known as 'heam' so can be useful for some people with anaemia.

Vegeterian is always the Healthy Option ? ....

False Food Myth - Some vegetarian dishes contain a lot of fat, especially if they're made with lots of cheese, oil, pastry or creamy sauces, or if they've been fried. So they aren't necessarily a healthy option.

In fact, red meat can be low in fat if it's lean and all the visible fat has been removed. Other low-fat options are chicken without the skin, and fish, if they've been cooked without too much fat.

But it's always a good idea to have some vegetables with your meal because we should be eating at least five portions of a variety of fruit and vegetables a day as part of a healthy balanced diet.

You shouldn't eat more than two eggs a week ? ....

Eggs have long had a bad reputation as a source of cholesterol. It is true that they contain cholesterol, but should only be limited if you know that your cholesterol levels are high, or you have had your gallbladder removed.

However, eggs are a valuable source of protein, and are beneficial for the immune system, as they can help raise levels of antibodies.

Remember that only 20% of cholesterol comes from food - the remaining 80% is manufactured by the liver.

Fruit juice is as good for you as fresh fruit ? ....

False Food Myth - Fruit juices contain nutrients in a highly absorbable form, but some water soluble vitamins, such as vitamin C, can be lost as the liquid evaporates, so ideally juice should be squeezed at home and drunk immediately.

Eating whole fruit does have some advantages over juice - for example, the pith of an orange contains flavanols which are thought to recycle vitamin C - increasing the potential benefit. This pith is lost in juicing.

Fresh fruit also contain fibre, juice is generally fibre-free, which can help balance blood glucose levels.

You should never drink water with a meal ? ....

True-ish - It's probably best not to drink more than one glass of water with a meal as excess water can dilute digestive enzymes. However, a little water is unlikely to do this, so drink if you are thirsty.

A large glass of water before a meal can contribute to satiety, the satisfied feeling of fullness, and perhaps prevent overeating.

Ice cold water is the best drink to satisfy thirst ? ....

False - Water is best drunk slightly below room temperature, as its' uptake in the body is increased at this level. You should remove your water from the fridge approximately twenty minutes before drinking.

Coffee gives you energy ? ....

Any rush of energy that you may feel after drinking a caffeinated drink is bound to be very short lived.

If you want to lose weight, remember that caffeine will slow down the usage of fat stores for fuel, and thus slow weight loss.

Most of the salt in our diet is added at the table ? ....

About 75% of the salt in your diet comes from processed foods. Just 10 to 15% comes from the salt we add when we're cooking or at the table.

On average we're eating about 9.5g of salt a day. But we should try to cut this down to no more than 6g of salt a day for adults.

Avocados are an unhealthy choice ? ....

False Food Myth - Avocados contain mono-unsaturated fat, which has a positive effect on blood cholesterol levels.

As part of a healthy diet it's important to reduce the amount of saturated fat we eat and replace it with unsaturated fat, as well as reducing the total amount of fat we eat. This means avocados are a healthy choice.

Half an avocado also counts as one of the five portions of a variety of fruit and vegetables we should be eating each day. However, avocados do contain fat and eating too much of any food containing fat can lead to weight gain if the energy isn't used up through physical activity.
