Bananas are quite caloric fruits, with a rather high carbohydrate intake. Together with grapes, mandarin and kako (in addition to a lot of tropical fruit, such as coconut, avocado, etc.), it could be called a winter fruit. Contains an average amount of fiber and little water.
Its portion must take into account that the mature ones possess a rather important glycemic index and therefore (in the sedentary) it is recommended not to eat more than 150g at a time. In the case of diabetes, hypertriglyceridemia and overweight, bananas are not the most recommended fruits for daily and customary consumption.
Furthermore, we recall that bananas are foreign plantation fruits (except for some small exceptions in the Sicily region) and therefore they do not necessarily have to respect hygienic protocols and European regulations regarding the use of chemical products.
Bananas are an excellent source of vitamin B6 and contain fair amounts of vitamin C and manganese.
Although bananas are considered an exceptionally potassium-rich food, their actual content is relatively moderate; in fact 100g of banana comply with only 8% of the average daily need. Since a medium banana with no skin weighs less than 200g, to reach even 60% of the recommended potassium intake for a sedentary subject would take about 4 bananas a day.
A list of common foods used in the United States shows that bananas rank at 1, 611, as they provide 358mg of potassium per 100g of edible portion. Foods that bring more potassium than bananas include: beans, milk, apricots, carrots, sweet green peppers and potatoes.
Banana intake can affect dopamine production (a nerotrasmitter) in people suffering from a tyrosine deficiency (ordinary amino acid); this, which is a precursor of dopamine itself, is contained in good quantities in the fruit.
Individuals suffering from latex allergies may be hypersensitive (cross-reactivity) to banana ingestion.
The presence of serotonin, dopamine and noradrenaline was observed in very ripe bananas.
