Hazelnuts May Boost Magnesium and Vitamin E Levels in Mature Adults

The majority of American adults do not get enough magnesium and vitamin E in their diets. A recent study suggests that eating hazelnuts may improve blood levels of magnesium and vitamin E in mature adults.


Participants in the study included 32 people age 55 and older who ate 57 grams (about one third of a cup) of hazelnuts daily for 16 weeks. The researchers took blood and urine samples and anthropomorphic measures at the start and end of the intervention to determine plasma concentrations of ?-tocopherol and serum concentrations of magnesium, lipids, glucose, insulin, and high-sensitivity C-reactive protein and urinary vitamin E metabolites.


At the conclusion of the study, the researchers found increased blood concentrations of magnesium and increased urinary levels of a breakdown product of alpha tocopherol. Alpha tocopherol is one of the TK forms of vitamin E. They also found that concentrations of fasting glucose decreased by 3.4% and LDL cholesterol decreased by 6.0%. In addition, total:HDL ratios decreased by 4.5%.


Researchers from Oregon State University led the study. It was published on December 1, 2018, in The Journal of Nutrition.
