Eating eggs is linked to developing prostate cancer, according to a new National Institutes of Health-funded study. By consuming 2.5 eggs per week, men increased their risk for a deadly form of prostate cancer by 81 percent, compared with men who consumed less than half an egg per week. Researchers followed 27,607 men who were part of the Health Professionals Follow-up Study from 1994 to 2008. For men who already had prostate cancer, eating poultry and processed red meat increased their risk for death.

Pregnant women who eat yogurt may put their future children at risk for developing asthma, according to new research in Denmark. Consuming low-fat yogurt while pregnant is directly linked to the development of childhood asthma and hay fever, and full-fat yogurt is associated with adolescent hay fever. Consuming low-fat yogurt was associated with a 60 percent increase in asthma and an 80 percent increase in hay fever, compared with zero consumption of low-fat yogurt. The 61,912 women who completed the food questionnaire were part of the Danish National Birth Cohort.
