Investigators will collect medical history and current medications from study participants- this is outlined in the HIPAA form. The two intervention groups will consist of those receiving almonds and those that are receiving a calorie matched snack. The almond dose will be provided as 20% of total energy (20% E) in the diet. This dose was selected based on a previous randomized trial examining lipid parameters in response to 0, 10%, and 20% E as dietary almonds and a recent meta-analysis of intervention trials of tree nuts [23,24]. The control snack will be a typical western diet snack. The calorie-matched control snack will be commercially available individually wrapped food products such as a small granola bar + pretzels. Once a subject has met inclusion criteria and has signed IRB consent, anthropometric data will be obtained, 3-24 hour recall will be collected by phone, skype, or in person by a Registered Dietitian, training will be provided for recording dietary records, and estimated caloric needs will be calculated. Estimated energy needs (EER) will be determined using the Mifflin-St. Jeor equation and total daily energy needs (TDE) calculated as EER x activity factor of 1.3-1.5 for sedentary to average activity, or a higher activity level as indicated. A representative example of a 60 year old woman, 5'4", 140 pounds with typical activity level yields TDE of approximately 1,600 - 1,800 kcal/day, and 20% E of 320-360 kcal/day. The dose of almonds would be 2 ounces (equal to 23 whole kernels)/day, providing 328 calories.
