This study has been attacked by Dr. William Fair, a leading US urologist and a colon cancer survivor. Dr. Fair says that he himself takes 1,200 mg calcium a day. Giovannucci confirmed his results on repeating the study on a smaller group of men in Sweden. For calcium and protein intake, no associations were observed. But this study in the Netherlands did not compare fruit versus calcium consumption.
Vitamin D does protect men from prostate cancer.
In the USA and many countries, milk is fortified with vitamin D. Even so, calcium in mik and other foods lowers the amount of usable vitamin D in the body. Eating several servings of fruit a day keeps the level of vitamin D raised. Eating a diet high in meat and milk and low in fruit reduces the level of this anti-prostate cancer vitamin. A recent study of men diagnosed with prostate cancer in Quebec, Canada found that the men who consumed the hiegest amount of saturated fat were significantly more likely to die of prostate cancer than of other causes. The Harvard researchers say they took account of fat in calcium-rich foods and that still the balance between calcium and fructose was more important.
