Apparently gelatin is the latest “superfood”. Yep, the stuff in jello. Of course, you have to take away the added sugar, colour, and flavour for it to ascend to “superfood” status. You all know how I feel about “superfoods”. They’re a super scam. Sure, many of them are nutritious (think avocados and blueberries) but there’s nothing about them that makes them superior to other fruits and vegetables.
Okay, even if gelatin isn’t a “superfood” is it exceptionally good for you? Should we all be eating plain jello or taking gelatin capsules? Let’s take a look at the specific claims in the article…
Improved digestion – According to pretty much every wellness blog and self-proclaimed nutritionist gelatin improves digestion. However, as far as I can tell there is no scientific basis for this claim. I can’t find any research on the topic. This isn’t to say that gelatin doesn’t help digestion, but we don’t currently have any reason to believe that it does.
Reduced food intolerance and allergy – This is a frightening claim. It would be lovely if it were true; people with peanut allergies could eat some gelatin and then chow down on some peanuts. And what about those people who suffer from gelatin allergy?
Strong bones and flexible joints – Because gelatin is made from animal cartilage (unless it’s the vegetarian variety which is made from seaweed) it’s easy to see how people draw the connection between gelatin and joint and bone health. However, despite this widespread belief, there’s no evidence to support the use of gelatin for bone and joint health. The same applies for Thick hair, strong nails and healthy teeth. Just because a substance (e.g. collagen) acts to strengthen our hair doesn’t mean that it will do so if we consume it orally. Otherwise, we would be able to improve our eye sight by eating eyeballs. A bit of an exaggeration, but you get the point.
Ageless skin – See the last point above. I’d also like to add that skin ages! Sorry, no matter what supplements we take, and what lotions and potions we apply we are all going to get wrinkles. Want to retain your youthful complexion for as long as possible? Eat a healthy diet with a variety of fruits and vegetables and fluids, get enough sleep, exercise, avoid tanning and sunburns.
Improved sleep – I was able to find one study that suggested that 2 grams of glycine ingested at bedtime improved subjective sleep quality. There’s 1.3 g of glycine in one serving of gelatin so it’s possible that you might obtain some benefit from it. However, this quantity may not be present in capsules so before you go running out to buy them before bed you might want to make sure that you’re getting what you’re paying for.
