Antioxidants such as vitamin A and beta carotenes are important vitamins for memory. Antioxidants prevent some of the damage to cells in the body (and brain cells) from free radicals. As described in this article, antioxidants in fruits and vegetables may have improved health effects compared to antioxidants consumed through supplements.
Another study, which is discussed below, suggests that not all natural sources of antioxidants have similar effects on our health. The researchers tried to answer the question ‘how do the antioxidants from different fruits perform in our body?’ Antioxidants from a kiwi turn out to have far more effects on our health than antioxidants from a plum, for example.

Antioxidants’ reputation has been built up, and broken down by scientific research. Although some studies have found great health benefits after subjects took supplements with antioxidants, others did not find these health benefits of these supplements – and even warn for taking too many antioxidants. On the other hand, many researchers and health experts point to the many benefits of having a diet with high antioxidant levels. How can you make sure you get enough of these vitamins for memory?

Some vitamins for memory, such as caffeine, have an effect on the reward system in the brain. One important neurotransmitter (a chemical through which the brain cells communicate) in this reward system is dopamine. Dopamine is tightly related to learning and memory, because it is thought to control the reward system that helps positive experiences.
Dopamine has been studied extensively, but never have the levels of dopamine been decreased to almost zero in a living being. This would almost certainly kill any living creature, because it would not be motivated (to eat, for example) nor would it be able to learn. Or would it? Riemensperger and his colleagues tried to answer that question by eliminating dopamine in a fruit fly called Drosophila melanogaster. (more…)
