Rodney Bilton, emeritus professor of biochemistry at Liverpool John Moores University :- don't cook with olive oil - but DO eat unripe bananas: Think you know all the rules on healthy eating? A top scientist has lots of surprises

Olive oil, particularly extra virgin oil, is best used as a salad dressing and not in cooking, because it starts to burn at a comparatively low temperature and therefore breaks down easily.

Most of us cook with oil, but over heating can break down cooking oils, producing toxic chemicals called lipid peroxides. When eaten, they can react with proteins and DNA - your cells' genetic blueprint - in ways that are believed to increase the risk of cancer and heart disease.

When frying, a good tip is to emulate the Chinese and add a small amount of water to the wok or frying pan. This lower s the frying temperature of the oil to 100c and reduces the amount of oxidative damage to the fat which normally occurs


 

Eat unripe bananas
Green bananas, along with whole grains, vegetables and fibre, all contain resistant starch. This is the most important form of soluble dietary fibre you can eat - soluble dietary fibre is not digested in the small intestine, but is absorbed more slowly further down in the body, where it is fermented by bacteria in the colon to give long-term energy.


 

Drink water to reduce back pain
As many as 75 per cent of us may be chronically dehydrated, according to U.S. research. 

This not only affects our waistlines, but our backs, too. Preliminary research suggests that drinking eight to ten glasses of water a day could significantly ease back and joint pain for up to 80 per cent of sufferers. This is because being dehydrated makes the blood and joint fluids thicker; it also causes crystals of uric acid (a bodily waste substance normally removed in urine) to form in the joints, which can cause gout-like pain.
Drinking water is also a valuable and painless aid to weight loss. Even a mild state of dehydration will slow our metabolic rate by as much as 3 per cent and may play a role in weight gain.

Why you should beware of tofu
Vegetarians who consume tofu and bean curd as a total substitute for meat put themselves at risk of mineral deficiencies because they usually ignore a simple lesson on the way these foods are eaten in Japan.
These products are made from soy beans high in a substance called phytic acid. This can block absorption of essential minerals such as calcium, magnesium, copper, iron and especially zinc.
