– Spinach, chard and beets: Of course we do not have to remind you that these foods are considered some of the best sources of energy. They are also rich in oxalates that work as a vital element for nourishing the good bacteria in your gut.
However, if you are prone to kidney stones, the excessive intake of these foods will make things worse. In this case, the kidney will not be able to filter these substances causing the formation of these stones. Replace these foods with cabbage and broccoli, for example, because they contain fewer amounts of oxalates.
– Tuna: Tuna contains large amounts of protein and omega-3 fatty acids, but the tuna cans contain mercury, which also contributes to the damage of the nervous system and the brain cells of the fetus and children. As for adults, its effect ranges between numbness, and problems in the vision and weakening of memory if eaten in large quantities.
– Red meat, shellfish and white beans: As for these foods, they are important sources of iron which is the main element in making the red blood cells needed for transferring oxygen to the muscles. While iron deficiency contributes to the feeling of physical weakness, however, the excessive consumption of it causes serious liver problems.
