Walnuts prevent heart disease

A new clinical study shows that substituting walnuts for monounsaturated fat in a Mediterranean diet improves, and even restores, endothelial function (the property of arteries to dilate in order to meet an increased demand of blood, for instance due to a physical effort). Walnuts also reduce harmful cell adhesion molecules which are associated with atherosclerosis, commonly known as hardening of the arteries. These dual effects enhance the circulatory system, therefore aiding in the prevention of heart disease.

Breast feeding increases choline which means more brain cells

Five years ago, University of North Carolina at Chapel Hill researchers first reported finding that the nutrient choline played a critical role in memory and brain function by positively affecting the brain’s physical development. Differences in development influenced action, the scientists and their colleagues found. In animal experiments conducted at Duke University, both young and old rats performed significantly better on memory tasks if they received enough choline before birth compared with same-age rats whose mothers were fed choline-deficient diets. The latter showed deficits in the hippocampus and septums of their brains.

Japanese study raises concerns for childhood health issues

The number of children suffering from mental disorders and health problems such as allergies and asthma has risen sharply over the past decade in this country. The United States and European countries are also facing the increasingly serious problems of premature births and childhood obesity, in addition to allergic reactions. Many experts say the rise in health problems involving children is related to the use of chemicals in our daily lives and the impact of medical treatment provided to the children's mothers.
