Kale helps with liver, stomach and intestinal problems. Thanks to its high fiber content, it has a beneficial effect on digestion. It also helps in lowering cholesterol, strengthens blood vessels and the immune system. It's an significant source of folic acid, which is important for the blood-forming and healthy development of the fetus. It also protects against breast and prostate cancer. Minerals such as manganese, sodium, potassium, magnesium, copper and iron are widely represented.

100g (3.5oz) of kale contains up to 308% of reference daily intake (RDI) of vitamin A, 200% RDI vitamin C and 1021% RDI vitamin K. Vitamins A and K are soluble in fats, that's why I recommend using tuna in olive oil, not in water for this recipe.

After a gentle heat treatment, the kale will even give you some more health beneficial substances than raw kale. So come to try this tasty kale salad with pineapple, tuna and arugula.
