Brief summary: The purpose of this study is to identify if healthy cookies high in linoleic acid can change sleep quality and sleep architecture, blood fatty acid composition and be consumed with high compliance after eight weeks of consumption. The hypothesis is that consumption of healthy cookies for 8 weeks will improve sleep quality, increase linoleic acid in the blood and be consumed with greater than 80% compliance.

Detailed description: Overall, linoleic acid has many health benefits including altering body composition and energy metabolism, but is not clear if linoleic acid consumption can influence sleep quality.

The investigators plan to test the central hypothesis and accomplish the overall objective of this research by pursuing the following specific aims

Aim 1) To determine the effect of healthy cookies made with linoleic acid-rich oil on measures of sleep quality and sleep architecture in overweight adults

Aim 2) To determine the effect on plasma fatty acid composition and markers of circadian rhythm in peripheral blood mononuclear cells (PBMC) after four and eight weeks of consuming one healthy cookie per day

Aim 3) To measure the effect of healthy cookies made with LA-oil on change of lipidomic profiles of plasma and PBMC after four and eight weeks of consumption

Aim 4) To determine the feasibility of adherence to consuming 1 healthy cookie per day in place of snack for eight weeks
