Scientists from Rutgers University found that spinach really does boost strength. The secret behind this, they reveal, is that this green vegetable contains phytoecdysteroids, a type of steroid that increases the development of muscles.
As a part of their study the researchers used extracts of phytoecdysteriods on lab samples of human muscle, and found that it speeded up muscle growth by 20%. According to the New Scientist, on conducting trials on rats, the researchers found that spinach extracts made the rodents stronger within a month.
Researchers state that eating spinach is not only a good idea if you want strong muscles, but also if you want to keep eye disease, teeth, gum problems and anaemia at bay. Apart from this, it has also been found to have heart benefits. Research has shown that the vegetable can strengthen hearts, reduce the risk of a heart attack and boost survival rates by a third for attack victims.
