About

The aim of this study is to determine whether dairy or plant based fats combined with fish oils can alter skeletal muscle mitochondrial, physical, and cognitive function.

Full description

Physical and cognitive function decline as we get older and this may be due to changes within the mitochondria, organelles that regulate energy production in our cells. The ability of the mitochondria to produce energy can be affected by diet, and the composition of lipids in the cell is an important factor in determining how effective our mitochondria are. Dairy and plant based lipids differ in composition and therefore may differ in their ability to affect mitochondrial function when combined with fish oils (FO). The primary objective of this study is to determine whether supplementation with dairy or plant based fats combined with fish oils can alter skeletal muscle mitochondrial function. Additional exploratory objectives are 1) skeletal muscle and physical function and 2) cognitive function.
