简要总结
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. Our research team will evaluate three different groups: the first group will be chosen using a predictive analytics model that predicts who will benefit most from the MIND diet, the second group will follow the MIND diet without being pre-selected, and the third group will eat a standard healthy diet to serve as a comparison.
The main questions it aims to answer are:
Does the MIND diet improve cognitive performance and heart health relative to a control diet? How does the health impact of the MIND diet in participants pre-identified through predictive analytics compare to those without such pre-selection? Which of the three groups - predictive analytics selected MIND diet group, standard MIND diet group, or healthy control - demonstrate the most significant improvements in cognitive and cardiovascular health over the course of the trial?
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.
详细描述
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.

研究组 & 干预措施
Standard 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. This will be a standard treatment arm without prior selection through predictive analytics. The treatment meals will follow MIND diet guidelines and include leafy green vegetables, nuts, legumes, whole grains, berries, and extra virgin olive oil.
干预措施: MIND Diet (Other)
Predictive Analytics informed MIND Diet
Participants in the active MIND diet group informed by predictive analytics will be pre-identified based on the results of a machine learning model that predicts who will most likely benefit from the MIND diet. The participants in this 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.
干预措施: MIND Diet (Other)
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).
干预措施: Control Diet (Other)
