2. Arginine

Arginine, an amino acid, increases HGH. Studies indicate that you need about 15-20 grams per day. That is quite a bit, so choose foods carefully. Turkey breast is the highest in arginine, at 16 grams per breast.

Other foods high in arginine include pork loin, chicken, pumpkin seeds, soybeans, and peanuts. In order not to gain too much weight, you may need to supplement your arginine-rich foods with a supplement.
