Sugar is actually good for your body as long as it doesn't get too much at once. The problem with processed sugar is it gives your body too much sugar at once, and it doesn't give you the other things your body needs.

Your body's main source of energy is a type of sugar called glucose. Glucose is like fuel for your body's gas tank. There are many different kinds of sugar, but your body turns them all into glucose. Then your body uses the glucose as fuel for everything from thinking to moving. Our bodies slowly turn a lot of other food into glucose too, which is why things like bread and rice still give us energy even though they're not sweet.

Because our bodies need sugar, they try to make us eat lots of it. They do this by telling us sugar tastes sweet and good. This is why we like sweet things - it's how our body convinces us to eat the sugar we need for energy.

But sugar isn't the only thing our bodies need. Just like a car also needs oil, your body needs other nutrients, like protein, fiber, vitamins, and of course water. Your body can't taste all of these things, but in nature we would get all of these things anyway just by eating and drinking what we can find when we're hungry or thirsty.

In nature, fruit is one of the foods with the most sugar, and this is part of why it's good for us. Before we invented processed sugar, people loved fruit because they thought it was so sweet. Fruit has a lot of other things our bodies need too, like fiber, water, and vitamins. So when we eat fruit, we get the sugar we need, but also a lot of other things our bodies also need.

Processed sugar is actually made by taking the sugar from fruits and leaving the other good stuff behind. This make processed sugar very sweet, and a powerful source of energy. But because it doesn't have all the good stuff, it's not nearly as good for you as fruit. If all you ate was processed sugar, you'd die because you wouldn't get any of the other stuff your body needs.

Also, getting enough energy from food isn't as big a problem for most people these days like it was when we all lived in nature. In fact, a lot of people get too much energy. When you eat processed sugar, you get way more energy than with fruit, because the sugar's not mixed in with other things. Your body turns the extra energy it doesn't need into fat. This can cause health problems if there's too much.

And because processed sugar isn't mixed in with a whole lot of other food, your body always gets a huge amount of it all at once. This is hard on your body, because it has to suddenly work really hard to turn all of that sugar into glucose all at once. Over time, this can cause things like diabetes. With fruit, your body gets the sugar more slowly. It's like how when just a little bit of gas burns in a car engine, it makes your car move, but if you light a lot of gas on fire suddenly, it can explode.
