6. Poor diet
Our diet affects our brain, which is why it’s so important to eat well. Poor nutrition weakens mental functions and causes us to under-perform. A healthy diet doesn’t only help our brains work better, but it also improves our physical health and our self-esteem.
What to do: To make sure that our bodies and brains are getting all of the nutrients it needs, you don’t necessarily need to only eat those “miracle” foods that everyone is talking about. Eat more fruits and vegetables and cut down on processed meat (like hamburgers, hotdogs, and cold-cuts). Also try to reduce your intake of sugars and salt, especially in pre-packaged foods. Drink water when you’re thirsty and stay away from sugary drinks (even if they’re diet).
