7 Canned Tuna
Another product with a lot of vitamin D is tuna. Its advantages are availability and low cost. 100 g of canned tuna contains up to 236 IU of vitamin D. In addition, tuna is a source of vitamin K and niacin.
However, doctors do not recommend eating tuna often. This is because the product may contain traces of mercury and other toxins that, when accumulated in the body, cause health problems. Therefore, you should not eat more than 100-150 g per week.
