Brief Summary

The goal of this clinical trial is to learn if increasing adherence to a Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet pattern improves brain and heart health relative to a healthy control diet in middle-aged adults.The main questions it aims to answer are:

Does the MIND diet improve cognitive performance and heart health relative to a control diet?

Researchers will compare the MIND diet group to a control (a healthy diet that does not match the MIND diet) to see if the MIND provides more benefit to health.

Participants will:

Consume one meal that follows the MIND diet or a control meal every day for 3 months Visit the lab before and after the 3 months of meals for tests. Keep a record of the food they eat during the study.

Detailed Description

The purpose of this study is to understand how a healthy diet is related to thinking ability and heart health. Participants will be asked to consume a microwaveable study meal or prepackaged smoothie every day for 12 weeks. These meals will be delivered to participant homes using Daily Harvest meal delivery service. The study meals and smoothies will follow either a dietary pattern thought to improve brain and heart health (MIND), or a control diet, and will include foods commonly found in grocery stores. Participants will not know which diet they are assigned to (active or control). Participants will also be asked to follow simple dietary guidance on a healthy diet in addition to the meals provided. Participants will complete a series of online forms or surveys. Additionally, participants will come to 4 in-person laboratory visits to complete several computer-based tests of memory and attention while wearing an EEG cap. Participants will also be asked to complete an eye test, a heart rate and blood pressure assessment, a bone and body scan called DXA, and a blood draw at the beginning of the study and again at the end of the 12-week diet period.

Study Groups

MIND Diet

Participants in the active MIND diet group will be asked to consume one ready-to-eat meal per day from Daily Harvest® meal delivery service. The treatment meals will follow MIND diet guidelines and include leafy green vegetables, nuts, legumes, whole grains, berries, and extra virgin olive oil.

Group Type: EXPERIMENTAL

MIND Diet

Intervention Type: OTHER

Daily meals designed to increase adherence to the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) dietary pattern.

Control Diet

Participants in the control diet group will be asked to consume one ready-to-eat meal per day from Daily Harvest® meal delivery service. The Control group will receive daily meals that are isocaloric with the active/experimental meals but will follow a general diet based on the average American diet and Dietary Guidelines for Americans (i.e., vegetables, fruits, nuts, whole grains, and unsaturated fats).

Group Type: ACTIVE_COMPARATOR

Control Diet

Intervention Type: OTHER

Daily meals designed to increase fruit, vegetable, and whole grain intake consistent with a healthy American diet.
