Is seedless watermelon too high on the glycemic index?

And I personally LOVE to eat watermelon at any time of the day, but particularly in the morning or after or during a workout. Watermelon juice is by far my favorite juice of all!

Of course, pretty much all the watermelon you find everywhere is SEEDLESS.

Watermelon is also “pretty high” on the glycemic index compared to other fruits (at 72 compared with pure table sugar at 58).

For those reasons, a lot of people are avoiding watermelon and instead consume low-sugar fruits such as little green, acidic/tart apples or grapefruits.

And that my friend, is a big mistake.

You’re missing out on one of the best fruits on the planet just because you’re getting caught in numbers or the unverified hype of some “expert”.

First, let’s talk about the seedless issue.

The reason why seedless watermelon is popular is because people don’t really like to eat watermelon seeds or spit them out, and also because seedless watermelons have a longer shelf life.

They last longer because they’re more dense and have no seeds inside to break down the flesh.

The process for growing seedless watermelon might sound a little complicated, but it’s actually not anything GMO-related. It’s just a matter of crossing two plants together with the right set of chromosomes.

It’s been discovered over 40 years ago that if you cross breed a watermelon with four sets of chromosomes with one that has only two, you end up with a watermelon with three sets of chromosomes.

Follow so far?

The result is something that’s called a triploid seed (“tri” stands for three) and when grown the watermelon won’t reproduce itself and thus has no viable seeds.

They’re not always completely seedless by the way, and you may have noticed they often contain little edible white seeds.

You might not know that in order to produce seedless watermelons, seeded watermelons are planted *just for their seeds*, and in a big field of seedless watermelon you’ll find about 25% regular seeded watermelons that are used for their pollen so that bees can cross pollinate the other melons.

It’s actually not that much more complicated than the other cross-breeding techniques and grafting techniques that have been used in agriculture for thousands of years.

People who call seedless watermelon “unnatural” are eating a ton of foods that are cross-bred also without even knowing it, yet turning their nose up to seedless watermelon.
If you want to go full-on “natural”, the only way to go is to eat only truly wild foods and I don’t see a lot of benefits for doing that. If you are foraging all of your own food and taking only what was not planted by humans, you’re going to be doing a lot of work just to get enough to eat.

*What About the Glycemic Index?*

People like to get caught up in numbers for no reason, and avoid perfectly healthy foods like seedless watermelon just because someone created a neat little chart they could follow with foods to eat and foods to avoid.

But based on what?

The glycemic index measures the rise in blood sugar after eating specific foods. I’ve already debunked the myth that the glycemic index is terribly important in my new book “The Raw Vegan Coach” (which is no longer available on its own but is now included as part of the Raw Health Starter Kit:

The truth is, a higher glycemic index is sometimes a good thing.

Sometimes you DO want to eat something that will bring your blood sugar back up.

That’s why I find watermelon to be the perfect post-workout food, as well as a “lift-me up” kind of fruit when your energy is low.

Also, you have to take into account your entire state of health and the ability for your body to handle sugar and carbohydrates.

On a low-fat diet, with enough exercise, you will improve your insulin sensitivity and therefore you should be able to eat all kinds of fruit without problems.

But if you keep eating oil and fat every day, then any carbohydrate you eat will send you into an unnecessary blood sugar swing.

Watermelon is very high in water content and electrolytes, it is a food that is assimilated very quickly and helps rehydrate your body. Which means it’s perfectly healthy to eat a large bowl of watermelon for breakfast. You’ll feel instantly refreshed and rehydrated without the need to drink copious amounts of water to flush out your system every morning.
