Abstract

It has been estimated that 30–40 percent of all cancers can be prevented by lifestyle and dietary measures alone. Obesity, nutrient sparse foods such as concentrated sugars and refined flour products that contribute to impaired glucose metabolism (which leads to diabetes), low fiber intake, consumption of red meat, and imbalance of omega 3 and omega 6 fats all contribute to excess cancer risk. Intake of flax seed, especially its lignan fraction, and abundant portions of fruits and vegetables will lower cancer risk. Allium and cruciferous vegetables are especially beneficial, with broccoli sprouts being the densest source of sulforophane. Protective elements in a cancer prevention diet include selenium, folic acid, vitamin B-12, vitamin D, chlorophyll, and antioxidants such as the carotenoids (α-carotene, β-carotene, lycopene, lutein, cryptoxanthin). Ascorbic acid has limited benefits orally, but could be very beneficial intravenously. Supplementary use of oral digestive enzymes and probiotics also has merit as anticancer dietary measures. When a diet is compiled according to the guidelines here it is likely that there would be at least a 60–70 percent decrease in breast, colorectal, and prostate cancers, and even a 40–50 percent decrease in lung cancer, along with similar reductions in cancers at other sites. Such a diet would be conducive to preventing cancer and would favor recovery from cancer as well.

Highlights

  • The field of investigation of the role of nutrition in the cancer process is very broad

  • The apoptotic index was 3-fold higher in the resected prostate tissue, compared to biopsy tissue [151]. These intervention studies raise the question of what could have been done in this intervention was longer and combined synergistically with other effective intervention methods, such as flax seed, increased selenium and possibly vitamin E, in the context of a diet high in fruits and vegetable?

  • Men in top quintile of serum γtocopherol had 5-fold reduced risk of prostate cancer compared to lowest quintile Adjusted OR = 0.35 Results not statistically significant

Summary

Background

The field of investigation of the role of nutrition in the cancer process is very broad. A meta-analysis of nine cohort and case-control studies revealed an association between flax seed oil intake or high blood levels of alpha-linolenic acid and prostate cancer risk [79]. The apoptotic index was 3-fold higher in the resected prostate tissue, compared to biopsy tissue [151] These intervention studies raise the question of what could have been done in this intervention was longer and combined synergistically with other effective intervention methods, such as flax seed, increased selenium and possibly vitamin E, in the context of a diet high in fruits and vegetable?. It will be very interesting to follow the results of this study
