It has long been known that tomatoes possess many health benefits. Whether you eat them raw in salads and sandwiches, or cooked and processed into soups, purees, pastes and sauces, the good news just keeps on coming.

We’ve heard about their effect in preventing various types of cancer, of prostate and the skin, and the humble fruit’s use against heart disease and stroke. Now it’s a great cosmetic too.

The benefits are credited to lycopene, the pigment behind the distinctive red skin and a powerful antioxidant.

Professor Birch-Machin, of Newcastle University believes tomatoes are a cheap and simple way of improving health and looking good.

After a joint study by Manchester and Newcastle universities, he said, “I went into the study as a sceptic, but I was quite surprised with the significance of the findings.”

The British Society for Investigative Dermatology’s annual conference was told that tests using ultra-violet lamps showed that tomato-eaters were a third better protected against sunburn at the end of the study than at the start. Other tests suggested a tomato-based diet boosted production of collagen, the protein that keeps skin supple.

Tomatoes also protect the mitochondria, the parts of cells that turn food we eat into energy. “Being kind to our mitochondria is likely to contribute to improved skin health, which in turn may have an anti-ageing effect,” Professor Birch-Machin said.

The researchers now recommend two tomato-based meals a day for optimum health.

We are often told that our nails can tell us a lot about our state of health. But do we know what to look for?

Charlotte Vohtz nails the subject in her book, Naturally Gorgeous, Essential Health and Beauty Sectrets.

Here are eight tips from the book.

1. White spots or flecks on nails indicate a zinc deficiency, which may have many causes — too much alcohol or even side effects from taking the contraceptive pill.

2. Ridged or brittle nails may highlight a calcium deficiency or lack of vitamin A.

3. Cracked or broken nails — in the absence of any other reason such as heavy manual work — may show up a lack of fluids. Dehydration can cause many conditions including blocked sinuses.

4. Nails which split easily may indicate a lack of fatty acids in the diet.

5. Dryness and very rounded and curved ends could be a lack of vitamin B12, which may be linked to an iron deficiency.

6. For super-healthy nails make half your diet consist of fresh fruit and vegetables, some raw. This will boost your intake of vitamins, minerals and enzymes.

7. Add foods rich in sulphur and silicon, like fish, broccoli and onions. Also foods high in biotin, such as soya and whole grains.

8. Foods like wild seaweed (kelp tablets will do), which contain iodine for the thyroid gland, an organ that plays a part in the growth of nails, hair, skin and teeth.

How to Boost Your Immune System — Part 3

Vitamin C is a well known dietary aid to improved immune system performance. Studies confirm this bit of folk medicine. The real debate is whether supplements really do help, or if natural foods are the only way.

Vitamin C is also vital for the body to make collagen, a key protein in skin and connective tissue which is said to improve appearance with age.

For most elderly people, vitamin C supplements are recommended, especially through the winter when local fruits may not be available.

The ideal supplements also contain substances call bioflavanoids, antioxidants derived from the pith of citrus fruits. These have been shown to increase the effectiveness of supplementary vitamin C.

Mushrooms are known to have certain health benefits. Supplements are now available which contain a number of useful types, especially Asian fungi with special properties.

Typical mushrooms for helping the immune system along are, maitake, cordyceps, shiitake, hericeum and reishi.

A mineral, often deficient in older people, is zinc. It can be found naturally in red meat, nuts, wholegrains and fish.

As a supplement it’s often taken with selenium, a combination used to combat infections.
