Neither proteins nor carbs play a significant role on one’s concentration; it takes a while for carbs to convert into glucose in our body up to four hours and proteins are not available till at least after four hours as well. Even then, that mix of foods is not guaranteed to target the brain and make you more alert.
Experts advise us with balanced diets containing various nutrients such as vegetables, fruits, whole grains and proteins. If we consistently eat a healthy diet, our performance in general will be enhanced and if not, this will decrease our ability to focus.
If you need to concentrate, you are advised not to eat too much or a heavy meal because this will make you feel sluggish due to the blood being diverted to the stomach – instead of the brain – for digestion.
On the other hand, people who do not eat enough because they are on a restrictive diet or they skip meals would experience hunger which is certainly distracting. Studies reveal that children who eat breakfast tend to have better memory than those who do not, nevertheless beware of the high- caloric breakfast as it impairs concentration.
High- fat diets can negatively affect our alertness. A study on rats revealed that rats fed with high- fat meals have poorer memory and learning than those fed with balanced diets. There are many vitamins and minerals claiming to enhance mental and physical health; if you are seeking to boost your concentration, magnesium and beta- carotene in addition to vitamins B& C are said to enhance brain power.
However, there is no definitive evidence – according to experts – that the aforementioned can help particularly with memory and concentration. Experts say you can take supplements but they cannot substitute the whole foods; you can take vitamin C as a pill but better by eating citrus fruits.
