Myths & Truths About Nutrition

Myth: Heart disease in is caused by consumption of cholesterol and saturated fat from animal products.

Truth: During the period of rapid increase in heart disease (1920-1960), Consumption of animal fats declined but consumption of hydrogenated and industrially processed vegetable fats increased dramatically.

Myth: Saturated fat clogs arteries.

Truth: The fatty acids found in artery clogs are mostly unsaturated (74%) of which 41% are polyunsaturated. 

Myth: Vegetarianism is healthy.

Truth: The annual all-cause death rate of vegetarian men is slightly more than that of non-vegetarian men (.93% vs .89%); the annual death rate of vegetarian women is significantly more than that of non-vegetarian women (.86% vs .54%) 

Myth: Vitamin B₁₂ can be obtained from certain plant sources such as blue-green algae and soy products.

Truth: Vitamin B₁₂ is not absorbed from plant sources. Modern soy products increase the body's need for B₁₂. 

Myth: For good health, serum cholesterol should be less than 180 mg/dl.

Truth: The all-cause death rate is higher in individuals with cholesterol levels lower than 180 mg/dl. 

Myth: Animal fats cause cancer and heart disease.

Truth: Animal fats contain many nutrients that protect against cancer and heart disease; elevated rates of cancer and heart disease are associated with consumption of large amounts of vegetable oils. 

Myth: Children benefit from a low-fat diet.

Truth: Children on low-fat diets suffer from growth problems, failure to thrive & learning disabilities. 

Myth: A low-fat diet will make you "feel better . . . and increase your joy of living."

Truth: Low-fat diets are associated with increased rates of depression, psychological problems, fatigue, violence and suicide. 

Myth: To avoid heart disease, we should use margarine instead of butter.

Truth: Margarine eaters have twice the rate of heart disease as butter eaters. 

Myth: We do not consume enough essential fatty acids.

Truth: We consume far too much of one kind of EFA (omega-6 EFAs found in most polyunsaturated vegetable oils) but not enough of another kind of EFA (omega-3 EFAs found in fish, fish oils, eggs from properly fed chickens, dark green vegetables and herbs, and oils from certain seeds such as flax and chia, nuts such as walnuts and in small amounts in all whole grains.) 

Myth: A vegetarian diet will protect you against atherosclerosis.

Truth: The International Atherosclerosis Project found that vegetarians had just as much atherosclerosis as meat eaters. 

Myth: Low-fat diets prevent breast cancer.

Truth: A recent study found that women on very low-fat diets (less than 20%) had the same rate of breast cancer as women who consumed large amounts of fat. 

Myth: The "cave man diet" was low in fat.

Truth: Throughout the world, primitive peoples sought out and consumed fat from fish and shellfish, water fowl, sea mammals, land birds, insects, reptiles, rodents, bears, dogs, pigs, cattle, sheep, goats, game, eggs, nuts and milk products. (Abrams, Food & Evolution 1987)

Myth: Coconut oil causes heart disease.

Truth: When coconut oil was fed as 7% of energy to patients recovering from heart attacks, the patients had greater improvement compared to untreated controls, and no difference compared to patents treated with corn or safflower oils. Populations that consume coconut oil have low rates of heart disease. Coconut oil may also be one of the most useful oils to prevent heart disease because of its antiviral and antimicrobial characteristics. 

Myth: Saturated fats inhibit production of anti-inflammatory prostaglandins.

Truth: Saturated fats actually improve the production of all prostaglandins by facilitating the conversion of essential fatty acids. 

Myth: Arachidonic acid in foods like liver, butter and egg yolks causes production of "bad" inflammatory prostaglandins.

Truth: Series 2 prostaglandins that the body makes from arachidonic acid both encourage and inhibit inflammation under appropriate circumstances. Arachidonic acid is vital for the function of the brain and nervous system. 

Myth: Beef causes colon cancer

Truth: Argentina, with higher beef consumption, has lower rates of colon cancer than the US. Mormons have lower rates of colon cancer than vegetarian Seventh Day Adventists 

Hi everyone

If you are interested in the subject of fat then please have watch this film with Dr Mary Enig.

What's your favourite fruit?

I have a few and it seems to change throughout the year. At the moment I am really into pears. Did you know that this fruit inspired the Renaissance painters as they loved drawing still-life portraits of this fruit... I wonder if they liked eating them as well.

The Romans loved this fruit and would often carry them on their marches as they kept their freshness and taste so well.

So what's in a pear?

Well underneath its tender, nutritious skin, the pear is rich in vitamins, minerals, anti-oxidants and fibre. They are low in calories and taste really sweet.

One medium-sized pear meets more than a tenth of one's daily vitamin C needs. Vitamin C promotes health in the body and help fight free radical damage.

The flesh of this fruit contains virtually no sodium or saturated fat and is really rich in potassium.

Pears are also a great source of roughage as they are high in fibre, which, in turn, helps to keep our bowel movement smooth and regular.

Many great desserts include pears because they taste delicious when baked, roasted or fried.

So go on have a great pear today and let us know what you think of this great fruit!

I do come across some strange things in my life - one of them was the other day when I walked past a sandwich shop only to see these packages of food. It kind of takes synthetic, processed foods to another level!

I am sure the real sandwiches in this shop were great but it got me thinking that so many people don’t realise that if they eat lots of packaged and processed foods that they’re probably not getting the necessary nutrients to be healthy.

You may have heard that apparently there are about as many obese people in the world as there are those who are starving. The difference between these groups is that one is overeating and one is under-eating: the similarity is that both are malnourished. Whilst those of us in the developed world have more than enough to eat, the food we’re eating is less nutritious than it used to be. In addition, we lead more stressful lives than we used to and our bodies need vitamins and minerals to help us recover from stress: so we are suffering both from how we live and what we eat, or rather what we don’t eat. Every process that takes place in our body (such as digestion, fat burning, thinking, breathing, walking and talking) requires vitamins and minerals. If we fill up on junk foods, processed foods, sugary foods, deep fried foods and takeaways all we deplete our body’s stores of nutrients. If we don’t replenish our stores, over time, we suffer from poor immunity and, ultimately, ill health; we’ll find it harder to concentrate and process information; we’ll have less energy; and we’ll find it more difficult to metabolise food and burn fat. The good news is that we can reverse this process. When we eat fresh, natural foods, we top up our stock of vitamins and minerals.

Let’s imagine for a minute or two that it’s mid-afternoon and you are hungry. You fancy a snack and you have two choices: an apple and a chocolate bar. What does each option give you? The apple will give you a steady release of energy; vitamin C, which is good for your skin, bones, blood and building immunity; potassium, which helps to regulate your water balance, blood pressure and your heartbeat; and fibre, which keeps your digestive system healthy and helps reduce the risk of colon cancer. The chocolate bar, on the other hand, will give you a sugar hit, which will cause your energy levels to crash; saturated fat, which increases your risk of heart disease – and nothing of any value. When you look at foods like this, don’t you think there’s little competition between them?

Food manufacturers refine foods to make them last longer and so they’re more profitable; but you deserve better than that. No matter what you might think about your body or how long you’ve been abusing it with poor quality food, your body deserves to have fresh, nutritious, natural food.

The Amazing DietGirl has been up to good good in the kitchen again... So, I thought some of you might like to see her take on how to make Almond-Butter.

Recently I talked about the old saying that “An apple a day keeps the doctor away.”

So have you been eating more apples? I have, especially the Pink Lady apple. In fact I used to go out with a girl from Australia whose father was the horticulturalist who designed the apple!

However, is it just an apple a day that keeps the doctor away? I don’t think so. What about the old banana then?

When you compare it to an apple, it has four times the protein, twice the carbohydrate, three times the phosphorous, five times the vitamin A and iron, and twice the other vitamins and minerals. It is also rich in potassium and is one of the best value foods around!

It contains three natural sugars - sucrose, fructose and glucose combined with fibre and a banana gives an instant, sustained and substantial boost of energy. Research has proven that just two bananas provide enough energy for a strenuous 90-minute workout. No wonder the banana is the number one fruit with the world's leading athletes.

But energy isn't the only way a banana can help us keep fit. It can also help overcome or prevent a substantial number of illnesses and conditions, making it a must to add to our daily diet.

So maybe it’s time to update that well-known phrase and say:

"A banana and an apple a day keeps the doctor away”

Now, is there another daily essential we should add...? What's your can't-live-without food? Put it in the comments...

Serves: 4-6. Cooking Time: 15-30 minutes

Be adventurous and make up your own soups with your favourite ingredients and seasonings. See what you have in the fridge or store cupboard, use leftovers and take the opportunity to buy fresh foods that are cheap and in season.

What you need: 

• 500g-1kg/1lb 2oz-2lb 4oz solids: vegetables, canned tomatoes, sweetcorn, beans, potatoes, rice, onions, garlic, pasta, etc.

• 1-1.5 litres/1½-2½ pints meat or vegetable stock, seasonings, spices and flavourings

How to do it: 

1. Simply sauté the chopped onion, garlic and any other hard vegetables in a tablespoon of oil, or soften and turn them a light golden brown, which brings out their sweetness and flavour.

2. Using a non-stick pan and covering it while you sauté the vegetables, so that they sweat as well as fry will mean using less oil, (you can speed up things by leaving out this stage and simply cooking all the ingredients together but it won’t taste as good).

3. Next add any softer vegetables (like tomatoes) and beans, rice, pasta, etc., plus the stock or water and simmer until everything is tender.

4. Taste and adjust seasonings. Decide whether you want to eat rough and chunky, blended with hand held blender bar until roughly chopped with a bit of texture, or completely liquidised until it’s velvety smooth.
