A healthy amount of sunshine may be the secret to staying young. British scientists have discovered.

Vitamin D is produced naturally by the skin in response to (对…的反应) sunlight and may help to slow the ageing process and protect against heart disease, according to the study.

Researchers from King's College London studied 2,160 women aged between 18 and 79, looking at their telomeres-a biological marker of ageing found in DNA. As people get older, their telomeres get shorter and they become more susceptible (易受伤害的) to certain illnesses.

But the study found women with high levels of vitamin D had comparatively longer telomeres-a sign of being biologically younger and healthier.

The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.

Lead researcher Dr Brent Richards said, "These results are exciting because they show for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D." This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer."

Professor Tim Spector, a co-author of the report, added, " Although it might sound absurd(荒唐的), it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process.

Vitamin D made by the action of sunlight on the skin accounts for 90 percent of the body's supply, but lower levels can also be got through food such as fish, eggs and breakfast cereals(粥).

Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.

But now I am making up for lost time---we do so much together and it is just great.”

Chris used to consume an incredible 5,000 calories a day, before he switched to healthy lifestyle. On average he would eat five slices of bread for breakfast as a mid morning meal before a full English breakfast. He would then eat a sandwich, a large pack of crisps and a pasty for lunch before chewing a whole packet of biscuits in the afternoon. For dinner Chris would demolish a curry(咖啡) and, ice cream, and also drink four pints of beer very quickly, before feeding on fatty snacks all evening.
