Cheese has been made and eaten by humans for thousands of years. Cheese is easy to digest and is very rich in some nutrients such as protein, fat, calcium, and potassium. On the negative side, some older aged cheese like Roquefort can contain molds and mycotoxins.
Like yogurt, cheese can also be used to carry probiotic or good bacteria like Lactobacillus. Such probiotic bacteria can reduce risk of intestinal infections and boost the body’s immunity. A Finnish study of 31 adults aged 72 to 103 years reported that consumption of a cheese containing Lactobacillus bacteria significantly improved the immune system. Immune system function was measured by increased activity of natural killer cells in the blood.
