Cancer & Nutrition: Myths and Facts (Part 3)

Here we have busted two nutrition myths which are not effective in cancer risk reduction.

1. Organic Food versus Cancer Risk

Explanation

There is currently no strong evidence to support the idea that organic foods can help protect against cancer compared with produce that is grown conventionally.

There is little evidence that organic produce has higher nutrient levels than conventionally grown produce.

Suggestion

– Organic food consumption is optional

– Healthy balanced diet is the key to provide essential nutrients to body

– Include two servings of fruits and two servings of vegetables daily (one serving is equivalent to size of a fist)

* 1 serving of fruit =


1 small apple, orange, pear, or mango (130g)	1 wedge of papaya, pineapple, or watermelon (130g)	10 grapes/longan (50g)

1 medium banana

* 1 serving of vegetable =


150g raw leafy vegetables	100g raw non-leafy vegetable	100g cooked vegetables

2. Supplement versus Cancer Risk

Explanation

There is strong evidence from randomised controlled trials that high-dose beta-carotene supplements may increase the risk of lung cancer in some people. There is no strong evidence that dietary supplements, apart from calcium for colorectal cancer, can reduce cancer risk.

Suggestion

– Supplements are to be prescribed by medical professionals only if populations are medically deficit on certain vitamins / minerals (pregnant women, elderly, patients receiving some medical treatment)

– Food is the best source of vitamins, minerals, and other bioactive food components
