A new study, published in The Journal of Nutrition, suggests that extreme dietary habits involving carbohydrates and fats affect life expectancy. Researchers from Nagoya University Graduate School of Medicine in Japan led by Dr. Takashi Tamura found that a low carbohydrate intake in men and a high carbohydrate intake in women are associated with a higher risk of all-cause and cancer-related mortality and that women with higher fat intake may have a lower risk of all-cause mortality.

It doesn’t seem conclusive… Just adds to the noise it purports to address.
