All things considered, the amount of food seems more important than eating specific
foods to try to prevent cancer.
About 40% of major cancers in the United States are due to obesity (and inactivity).
Similar to smoking, the onset of cancer occurs over decades due to unrelenting higher
levels of circulating insulin and blood sugar that stimulate cell proliferation.
Obesity is the single biggest factor in cancer risk increase over the past decade and now
surpasses tobacco as the leading cause of major cancer in North America.
Of course, there are certain foods that are more calorie rich gram for gram, such as
meat versus vegetables but cooking methods also add calories. Processed foods tend to
result in people ingesting more as well.
Calorie reduction and exercise are essential. After that, ingesting 5 or more servings of
fruit and vegetables is a healthier way of getting important vitamins and micronutrients
than taking a multivitamin. Multivitamin use is associated with higher cancer risk and
higher mortality.
This may have to do with the way micronutrients are absorbed and released at very low
dose continually, through about 20 feet of small intestine, compared to the big dump
and then excretion in the urine within hours of taking pills.
For those on a budget, frozen fruits and vegetables may have more micronutrients than
fresh because they aren˙t subject to degradation during shipping and shelf life in the
supermarket and kitchen counter.
You can˙t make up for poor lifestyle choices decade after decade by eating ˙anti-cancer˙
food.
Avoid obesity, inactivity, tobacco and alcohol. And eat your vitamins in your food and
vegetables instead of taking a multivitamin or supplement (unless recommended for a
specific medical condition such as short bowel syndrome or macular degeneration). Even
