The proteins found in gelatin, as well as the lithium, phosphorous, and copper, keep the bones strong and increase the mineral density of the skeleton. Gelatin can also be an important defense mechanism against osteoporosis, while the amino acids help fight arthritis.
Gelatin stimulates metabolism through its nutrients and amino acids. Fibre and protein, for example, satisfy and contribute to the feeling of satiety. Gelatin replaces calorie desserts and avoids excessive weight gain.
