This is a study that tracked 15,000 older male doctors for more than 10 years. They found those who took a multivitamin had 8 percent fewer cancers.
A multivitamin helps a little bit in addressing nutritional deficiencies in modern diets to the point of mildly reducing the risk for cancer.
However, certain nutrients such as those found in animal fat and internal organs, such as Vitamin D and A (the animal form Retinol) which have anti-cancer properties, need to be in much higher doses can can be found in a multivitamin.
Iodine, which can reduce the risk of reproductive system and breast cancers significantly (see David Brownstein MD’s book and work), needs to be closer to the Japanese mainland diet average – which is about 100 times more than in the usual American diet. The amount in a multivitamin is miniscule.
If the doctors were eating a much healthier traditional high density nutrient diet, they wouldn’t need a multivitamin, obtaining the nutrients they need from the diet itself. Unfortunately, high density nutrient diets are infrequently seen in modern times.
