The phrase that the poison is hidden in the dose is familiar to all of us. We offer you another proof of the truth of these words, indicating a list of otherwise useful foods that can be dangerous to health if not consumed properly and in reasonable quantities.

You can hardly imagine that nuts, fish and leafy vegetables are toxic to the body if large doses of them are taken. Let's find out why this is so!

Useful foods that can be dangerous to health

Spinach, beets, chard (spinach or beets)

Needless to say, vegetables are useful, including green leafy vegetables. They are recommended by nutritionists around the world not only because of their low caloric content, but also because of the rich content of vitamins and minerals. Apart from them, however, they contain natural compounds such as oxalates. The latter work as prebiotics in the body and are a favorable environment for the development of beneficial intestinal bacteria.
So far so good, but if you are prone to kidney stones, oxalates will catalyze this process. The kidneys need to filter the compounds and remove them from the body, but in people who are at risk of developing gallstones, the formation of stones is accelerated.
If in doubt, consult your doctor.

Canned tuna

Of course, canned foods cannot replace natural ones, but when it comes to tuna, nutritionists are in favor. The trade-off is due to the fact that it is an affordable source of protein and omega-3 fatty acids. But! There is always a "BUT". We can not ignore the fact that canned tuna contains a certain amount of mercury, which affects the nervous system and the brain of the developing fetus in pregnant women. Excessive concentrations of the substance are dangerous for adults, and the symptoms of poisoning are: tingling and tingling, vision and memory problems.
Experts do not provide information on a specific amount of canned fish, which could have an adverse effect on health, but it is recommended not to eat more than 120 grams of the product per week.

In the next part we will find out how and why Brazil nuts, brown rice, red meat and white beans can harm us.
