Sponsor's own description
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).
