Biology - 23 July - Antioxidants and Free Radicals

"People should still eat healthy food" - do we rely too heavily on supplements to provide antioxidants?

You try to improve your diet before you use supplements. That's because nutrients are most potent when they come from food. "They are accompanied by many nonessential but beneficial nutrients, such as hundreds of carotenoids, flavonoids, minerals, and antioxidants that aren't in most supplements.

"Aspirin a day could dramatically cut cancer risk"  What are your thoughts on this?
base on this research I agree:
More than 130,000 deaths would be avoided over a 20-year period if Britain's 50- to 64-year-olds took a daily aspirin for 10 years, because the beneficial effects continue even when the aspirin is stopped, the authors say.

A research team led by Professor Jack Cuzick, head of the centre for cancer prevention at Queen Mary University of London, concluded that people between 50 and 65 should consider regularly taking the 75mg low-dosage tablets.

Cuzick said that taking aspirin "looks to be the most important thing we can do to reduce cancer after stopping smoking and reducing obesity, and will probably be much easier to implement".

In a briefing to journalists, the scientist added that he had been dosing himself for the last four years, keeping the tablets beside his bed. "I take aspirin as part of a bedtime ritual every day and I can achieve that quite easily," he said.

However, to obtain the newfound benefits of the drug, people would have to take aspirin for at least five years and probably 10, the review said.
