Cancer Causing Food and Drink

Health News this Week

 

Tea Causes Throat Cancer

 

The coffee industry must have loved this headline. Researchers had to go all the

way to northern Iran to find tea drinkers that drank tea almost straight out of

the kettle.

We asked Yvonne Bishop-Weston a nutritionist in London. " No tea doesn't give you

cancer in fact many teas are so full of antioxidents it can help prevent

disease. The cause of increased risk of cancer in this study was really hot

liquid. The solution is simple – wait about 5 minutes for the tea to cool

slightly. "

 

" Waiting 5 minutes for the tea to brew has an added advantage of allowing

antioxidents to infuse more thoroughly too. My advice is to avoid teas with lots

of caffiene in too, such as black tea, which may have a detrimental effect on

some people's immune systems. My favourite is Rooibos , Rooibosch or Red Bush

Tea which is naturally very low in caffeine "

 

Oily Fish Prevents Prostate Cancer

 

Another red herring? NHS choices confirm " The study looked at fish and fatty

acids in the diets of men with and without aggressive prostate cancer. It found

that healthy men had a higher intake of omega-3 fatty acids, and interpreted

this to mean that omega-3 has a protective effect against cancer. It also found

that men with a particular gene variation that codes for the COX-2 enzyme had

increased risk of prostate cancer, and this risk fell with higher omega-3

consumption. "

 

Our London Nutritionist Yvonne says " Fish is not the only source of omega 3 and

not even the only source of long chain omega 3 fatty acids such as EPA and DHA

which many people have been shown to be short of in tests we run in our Harley

Street clinic. The long chain omega 3 fats EPA and DHA can be found in algae and

Echium Oil has been shown to be very effective in increasing EPA levels. 1 gram

of Echium oil has been shown to potentially convert to 300mg of EPA. Obviously

these oils, being sourced from plants are far more sustainable than extracting

oil from fish which is extremely wasteful and damaging to fragile marine

ecosystems. "

 

Vegetarian Diets Cause Cancer

 

Actually the research from Oxford university shows that vegetarians have lower

incidence of all cancers. In the trial made up of healthy omnivores, vegetarians

and vegans all participants had lower than average incidence of cancer than the

national average.

 

Within the study, the incidence of all cancers combined was lower among

vegetarians than among meat eaters, but the incidence of colorectal cancer was

slightly higher in vegetarians than in meat eaters.

 

" This blip in the usual statistics that support the hypothesis of vegetarian

diets as being healthier could be due to a greater reliance on dairy foods which

can be just as high in saturated animal fat and low in fibre as meat. It has to

be pointed out that the variation between the two groups of healthier eaters in

this trial is very small and just one or two consumers of hydrogenated fat rich

vegetarian foods could have skewed this unusual result. " says Yvonne,

Nutritionist, London
