A sweet treat that can’t be beat.

With summer in full swing, nothing sounds better than ending a long, hot day with a slew of desserts that delight the senses.

But one stands above the rest, delivering a boost to gut health, joint pain relief and anti-aging benefits — and it’s probably already in your pantry.

While the “Jell-O diet” of nothing but gelatin, vinegar and baking soda is a fake AI diet that causes stomach issues, the gelatinous dessert itself could have some sweet health benefits.

A primary ingredient in Jell-O, animal gelatin, can deliver an important material that makes up our entire body, including bones, cartilage and skin — collagen.

Gelatin is a flavorless, colorless thickening agent derived from animal collagen, namely the skin, bones and connective tissues.

But a jiggly Jell-O mold isn’t the only use for gelatin, as it’s commonly added to broths, soups, marshmallows, gummy candies, sauces and even some medications.

Since it’s derived from connective tissues and tendons that contain collagen, gelatin is chock full of the same proteins and amino acids.

Many even take it as a supplement to reap the benefits.

Similar to collagen, gelatin may promote skin, joint, hair and nail health, thanks to its amino acid content, which are the building blocks of protein.

Gelatin may also provide a boost of hydration to skin from replenishing collagen that people tend to lose as they age, leading to a loss of elasticity and development of wrinkles.

The thickening ingredient may also reduce joint pain by increasing the density of the cartilage and connective tissues.

And thanks to lysine, gelatin can also help improve calcium absorption to strengthen bones and reduce the risk of osteoporosis, or the thinning of bones.

Eating Jell-O made with animal gelatin could also improve gut health by supporting the intestinal walls and building the protective mucus lining.

While further research is needed in humans, some studies showed promising effects on rats’ intestinal health after consuming gelatin.

One amino acid in gelatin in particular, glutamic acid, can also protect the intestinal wall from damage and prevent leaky gut, a condition that causes bloating, constipation and acid reflux.

Another amino acid, glycine, has been shown to help manage blood sugar levels in those with type 2 diabetes, as well as reduce inflammation.

Nutritionally, gelatin is low in calories, with a tablespoon only containing 10 calories, 6 grams of protein, 2 grams of sugar and zero grams of fat.

If taken as a supplement, the National Institutes of Health suggests between 5 and 15 grams a day for up to six months is safest.
