Phenylalanine-rich foods

Foods rich in phenylalanine are those that contain many proteins, such as meat, fish and milk and dairy products. People with phenylketonuria have to control the consumption of phenylalanine, as they accumulate this amino acid in the body, which leads to problems such as delays in psychological development and seizures. We are a family owned and operated business.
