How were you able to identify each component in the MIND diet and ensure every part of the diet is good for brain health?

There have been animal models that use different berry extracts, like blueberries for example, which were then given to rodents, who were put through memory exercises. They learned that the berry-fed rodents had better memory function, and when they looked at the brains post-experiment, they saw that the hippocampus was larger in the blueberry-fed rodents. Anthocyanin is a type of nutrient that is very high in blueberries, and they found higher levels of anthocyanin in the rodents’ hippocampus when fed the blueberries. So perhaps anthocyanin has an important role in protecting our memories in the hippocampus.
