Hazelnuts boost magnesium and vitamin E

Older adults typically do not get enough magnesium or vitamin E in the diet.

In this study, 32 men and women, aged at least 55, consumed about 2 ounces of hazelnuts per day. There was no placebo group. After 16 weeks, magnesium levels had increased 2.1 percent and signs of alpha-tocopherol had also increased. In addition, glucose levels declined 3.4 percent, and levels of LDL—the “bad” cholesterol—declined 6 percent.

Because it is hard to measure changes in alpha-tocopherol levels, doctors instead measured a vitamin-E byproduct in the urine, which would only increase when the body is getting enough vitamin E.
