Oregon State University researchers say hazelnuts could raise the micronutrient levels in middle-age and elderly people.
According to UPI, the study followed 32 people age 55 and older, who ate two cups of hazelnuts a day for 16 weeks.
Results showed increased blood concentrations of magnesium and elevated urinary levels of vitamin E.
The researchers also noted a decrease in glucose and "bad" cholesterol, as well as an increase in magnesium.
This is one of the first times a study of this type has focused only on older adults. Alex Michels Study co-author and researcher
