cheese rich in tyrosine
The U.S. Department of Agriculture reports that cheese contains one of the highest natural concentrations of tyrosine. Grated Parmesan cheese has the most, with 1 cup containing 2.3 grams of the amino acid. Swiss cheese has 2.2 grams per cup, provolone contains 2 grams and mozzarella has 1.6 grams in each cup. A single serving of cheese is equivalent to 1 1/2 ounces of hard cheese or 1/3 cup of shredded cheese. To limit your fat, saturated fat and cholesterol intake, eat cheese in moderation and choose reduced-fat brands. Dry-roasted, unsalted peanuts contain 1.4 grams of tyrosine in each cup.
