Study Summary

With advancing age, older adults are susceptible to vitamin and mineral deficiencies for a variety of reasons. Nutrient-dense food sources of vitamin E and other key vitamins and minerals, like hazelnuts, may offer a simple means of improving nutritional status of healthy older adults. This hypothesis is that individuals eating hazelnuts everyday will result in measurable increases in magnesium and vitamin E levels, two under-consumed micronutrients among older adults. Thus, subjects will consume two ounces (56 g) of hazelnuts each day for sixteen weeks. Investigators will measure vitamin E and magnesium levels along with a general assessment of micronutrient status as primary outcomes. Since nuts are nutrient-rich sources of unsaturated fatty acids but low in carbohydrates, changes in fasting glucose, lipid and lipoprotein profiles, and BMI will also be determined (secondary outcomes).

Primary Outcome

Plasma levels of magnesium and vitamin E (alpha and gamma tocopherol) at baseline and 16 weeks after hazelnut intervention will be determined. Vitamin E analyses will be performed as absolute concentrations and concentrations corrected for total plasma lipids.
