Sodium

Source: Sodium is provided through food. It is found in most foods, but especially in table salt, milk and its derivatives, seafood, fish, water (whether mineral or source water) and vegetables.

What does it do? It is an element essential for life. It is particularly involved in hydration of the body, nervous system function and muscular contraction. It also helps maintain normal digestion, through the production of hydrochloric acid in the stomach. Be careful with table salt: Heavy consumption of table salt (sodium chloride) leads to an excess of sodium in the body and is a risk factor for high blood pressure.

For whom? Only sporting people should be careful about taking in sufficient sodium, because of the losses caused by sweating during exercise, but also because it facilitates good hydration when taken in with an energy drink, favouring its absorption (it helps make the drink "isotonic").

Recommended intake

There is no recommended intake for sodium. Sodium requirements are estimated at 1.5-2 g daily, that is, 3-5 g of table salt; however, consumption levels have reached 8-15 g!
