While there is no one-size-fits-all answer to this question, here are five fruits that have been shown to improve focus and concentration.
1) Apples: Because of the antioxidants present in apples, they help prevent damage done by unhealthy chemicals in the environment. Additionally, apples contain flavonoids such as quercetin, which has been shown to be helpful for cognitive function and memory recall.
2) Bananas: bananas are a great source of dietary potassium, which helps regulate blood pressure and maintain fluid levels in the body. They also provide muscle support with their high amounts of carbohydrates, fiber, vitamin C (which is important for immune health), and minerals like magnesium and zinc.
3) Grapes: One study showed that those who consumed grapes on a regular basis had improved SAT scores! This may be due to their beneficial effects on brain function, including increased glutathione production and better nerve cell communication.
In addition, grapes are a good source of monounsaturated fatty acids (MUFAs), vitamins A&D (vitamins needed for vision development), chromium (a mineral essential for healthy glucose metabolism), copper (for strong immunity!), manganese (important for energy production), niacin amide(an anti-inflammatory agent).
