Liver and Red Meat
Organ meats contain a lot of nutrients. The most common types include kidneys, heart, brain and liver; all of which are rich in iron. For instance, a beef liver serving that weighs a 100grams (3.5ounce), contains 6.5 mg of iron [6]. Organ meats are also rich in selenium, proteins, copper and vitamin B.
Red meat is quite filling and contains a lot of nutrients. It is also high in zinc, selenium, protein and a lot of B vitamins [7]. According to researchers, individuals who consume a good quantity of poultry, meat and fish regularly, may have a lower chance of iron deficiency.
