Who remembers Popeye's favorite food? Spinach, not for nothing, was chosen by the character of the drawing as allies to have more strength. This vegetable is rich in iron (important for the oxygenation of the blood), calcium, magnesium and potbadium, it participates in the formation of bones and teeth, muscle health and the prevention of cramps. It is also a source of vitamins such as complex A, B and folic acid, C, E and K. However, this high nutritional value can have its potentiated effect depending on the process of preparation.
DO NOT STOP NOW … YOU HAVE MORE
Researchers at the University of Linköping, Sweden, conducted a study, published in the journal Food Chemistry, to find the most effective way healthy to make the most of this potential.
Do not stop now … eat spinach. They examined the level of lutein in food, which is a fat-soluble natural pigment found in dark green vegetables. This antioxidant is important because it can reduce the immune cell inflammation of patients with coronary artery disease.
For evaluation, scientists bought spinach in a supermarket and cooked it in different ways. They fried, boiled and boiled for up to 90 minutes and measured the level of lutein. They also studied the level of lutein when spinach was chopped for salads and smoothies.

What is the best way to consume spinach? In badyzing the results, they found that the best way to get lutein was to mix raw spinach in a smoothie or fruit juice. It is even more advantageous to add a dairy product such as milk or yoghurt. In fact, when the spinach is cut into small pieces, the leaves release more lutein and the fat of the dairy ingredient increases the solubility of lutein in the liquid.
They also found that spinach heating by boiling or frying, for example, eliminates much of the lutein. In fact, when it is fried at high temperature, much of the lutein is degraded in just two minutes.
