Summary

This study tests whether the MIND diet, a mix of the Mediterranean and DASH diets, can improve thinking, memory, and energy in breast cancer survivors who have ongoing brain fog. Two hundred survivors who finished treatment 6 months to 3 years ago will either follow the MIND diet or their usual diet for 12 weeks, then be monitored for another 12 weeks. The goal is to see if eating more leafy greens, berries, nuts, and fish while cutting back on sugar and processed foods can ease cognitive complaints and fatigue.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
MIND diet (a combination of Mediterranean and DASH diets, emphasizing plant-based foods like leafy greens, nuts, berries, fish, and olive oil, while limiting saturated fats, sugar, and processed meats)
What this could lead to
If it works, this could point toward a simple, non-drug way to improve memory, focus, and energy in breast cancer survivors.
What could go wrong
This is an early-stage study with only 200 participants, and results rely on self-reported questionnaires. The diet may be hard to stick to, and any benefits might not be large or lasting.
