He said those long term, broad diet studies have not been conducted. Although he said studies showing links between high-antioxidant foods red wine, coffee etc do show health benefits. Large studies have repeatedly shown that, with the possible exception of vitamin D , antioxidant supplements have negligible positive effect on healthy people, at least in terms of important things such as preventing people getting cancer or dying prematurely.
And some supplements — notably vitamins A, E and beta-carotene — even seem to slightly raise the risk of disease and early death. The Guardian, 16 February, This spat has been going for a while then Alan Dangour, who conducted a similar study for the FSA said that the quality of some of the data included in the study was poor. He questioned if the authors had substituted accuracy for scope. Polyphenol antioxidants such as flavanones and flavonols were higher in organic produce than non-organic versions, as were antioxidant anthocyanins. When it comes to health insurance all fruits and vegetables count.
He suggested that the greater damage organic crops are exposed to from pests makes them produce more phenolic compounds antioxidants as part of their natural defence system. Some vitamins have anti-oxidant properties such as vitamin E, vitamin C and beta-carotene but the differences between organic and conventional produce are trivial.
While the World Cancer Research Foundation in its systematic reviews concluded there is a relationship between fruit and vegetable consumption and a lower risk of cancer, they did state that there was insufficient evidence to make any claim for antioxidants and plant phenolics. He said that polyphenols could actually inhibit the absorbtion of vital nutrients such as iron and zinc. And that cadmium quantity was dependent on soil type and couldn't be affected by organic farming processes.

The effects of cadmium, one of the heavy metals found to be higher in conventional cereals than organic cereals, on human health are well documented. A study in concluded that cadmium "is one of the most toxic elements to which man [presumably also woman] can be exposed at work or in the environment. Once absorbed, Cd is efficiently retained in the human body, in which it accumulates throughout life. Cd is primarily toxic to the kidney". The article goes on to list many other horrible effects that the chemical can have on the human body where it persists and collects for up to 30 years.
Cadmium, nitrates and nitrites are controlled by food safety standards. To which conventional foods also have to adhere. There is also conjecture over whether nitrates and nitrites are in fact unhealthy. Damian Carrington writes that "the researchers argue that cadmium accumulates over time in the human body and that some people may wish to avoid this, and that pesticide limits are set individually, not for the cocktail of chemicals used on crops.
It seems obvious, but actually organic food is a tough thing to define.
5 Organic Foods (Scientifically) Healthier Than Conventional
It essentially amounts to a labelling system that allows consumers to preference certain farming practices. The rules governing what can be considered organic differ from country to country. Our definition of organic farming recognises the direct connection between our health and how the food we eat is produced.

Artificial fertilisers are banned and farmers develop fertile soil by rotating crops and using compost, manure and clover. With greater nutrient and antioxidant density, every mouthful of fruit and vegetables produced organically can count for more. This constitutes an important addition to the information currently available to consumers.
Switching to organic foods could be equivalent to eating one or two extra portions of the recommended "five vegetables a day", say the team responsible for the most comprehensive study of organics to date. Damian Carrington writes in the Guardian:.

The international scientific team behind the new work Consumption of antioxidants has been linked to better health. This, along with the revelation that levels of cadmium, which is poisonous to humans, were considerably lower in organic food, has lead organic advocates to claim the study vindicates their long held belief that organic food is better for you. But questions have been raised over the study's methodology and assumptions. And whether it is possible to draw health conclusions from the results.
And are they nutritionally relevant?
I am not convinced. If you are quoting figures or studies, please provide a link to the original source.

Apart from sticking to his diet plan he also ensures that he intakes only chemical free tasty organically grown food. She majorly focuses on fresh fruits that keep her skin radiant and detoxifies her body.
As a former Miss World, she relies on homemade food such as curd, honey and lemon to keep her skin toned and moisturised. She makes sure that she uses Organic products along with her regular workout sessions. However, not merely in food but she makes it a point to use Organic products even in cosmetics. By choosing Organic over the conventionally grown fruits and vegetables these celebrities are taking their health seriously.
Additionally, they are also doing their bit conserving the environment. Other common food labels should also not be confused with organic labels. For example, the guidelines for certified organic beef include — among a number of requirements — access to pasture during a minimum day grazing season and no growth hormones. But the labels "free-range" or "hormone-free," while they must be used truthfully, do not indicate a farmer followed all guidelines for organic certification.
There is a growing body of evidence that shows some potential health benefits of organic foods when compared with conventionally grown foods. While these studies have shown differences in the food, there is limited information to draw conclusions about how these differences translate into overall health benefits. One common concern with organic food is cost. Organic foods typically cost more than their conventional counterparts. Higher prices are due, in part, to more expensive farming practices. Whether you go totally organic or opt to mix conventional and organic foods, be sure to keep these tips in mind:.
