A couple of interesting diet studies....
1. Is a Japanese diet really healthier than a North American one?
The Japanese culture’s diet is often tooted as being the healthiest in the world. This Japanese study just published at the end of July says that a traditional Japanese diet is associated with a lower risk of mortality, dementia, depression and obesity. But there is one caveat: reduce salt. When looking at 7 health-enhancing traditional foods (rice, miso soup, fish, green/yellow vegetables, seaweed, pickles, green tea) and 2 that are not as traditional but commonly eaten in Japan (beef and pork), this culture has a very high salt intake, and it needs to be reduced for the most benefits.

What is the paleo diet, and is it healthier than others?
The Paleolithic diet, meaning one that early Paleolithic humans (2.6 million to 10,000 years ago) ate before modern agriculture began, includes eating vegetables, fruits, nuts/seeds, fish, small amounts of lean meat, and eggs, but no grain, dairy and sugar. This diet trend has surged in the last few years, prompting scientists to study it. Research from Brazil published in late July analyzed the Paleolithic diet to prevent and control chronic diseases. It showed significant weight loss (including body mass index and waist circumference) in people who adopted the Paleolithic diet compared to diets based on doctor’s recommendations. Researchers felt that this result alone would help to manage many chronic diseases that are often triggered or exacerbated by obesity. They state that several other studies show this type of diet reduced heart disease and diabetes risks especially in menopausal women.
