Data from all 50 US states shows early onset breast cancer is on the rise in younger women under 40. This increase is alarming and cannot be explained by genetic factors alone nor by changes in screening given that women under 40 years are below the recommended age for routine mammography screening.

Artificial sweetener aspartame found to spike insulin levels in mice, and in turn helps build up fatty plaque in their arteries, which increases their risk of heart attacks and stroke. Aspartame is around 200 times sweeter than sugar, and tricks receptors in the intestines to release more insulin.
