**7. Conclusion**

Researches are evident that the DASH diet and the Mediterranean diet improve cognitive function and development [35, 36]. By the support of these studies, the two diets have been combined to construct a hybrid MIND diet which is specifically designed to improve brain health. The MIND diet lays emphasis on the regular intake of leafy green vegetables, other vegetables, berries, legumes, fish, nuts, and whole grains whereas it limits butter, cheese, and red meat consumption. Studies suggested that the MIND diet can slow down age-related cognitive decline and reduce the risk of Alzheimer's disease [37, 38]. The Dukan and Atkins diets radically cut carbohydrates and fat in favor of protein, while the Palaeolithic diet greatly restricts starch in favor of fat and protein. These nutrient imbalances have beneficial effects only in the short term, especially on weight loss, but there are serious doubts about their long-term results. Whereas in the MIND diet, all the nutrient groups are included and a variety of nutrient sources are recommended in the right proportions, as per international nutritional recommendations. The MIND diet is also found to be a good source of carbohydrates, protein fat, and all other nutrients. Adherence to the MIND diet will improve brain health, and slow down cognitive decline in individuals with Alzheimer's disease.
