".How Sugar Really Affects Your Cholesterol.
If you’re like most people, you probably think it’s high-cholesterol foods like eggs or shrimp that are the worst
for your cholesterol levels But that’s not really the case.
Because it’s not actually the cholesterol in food that’s the problem. Most of the cholesterol that circulates inside
our bodies is made inside our bodies, and not absorbed from the diet. So, it’s not about avoiding foods that naturally
contain cholesterol, it’s about avoiding foods that prompt our bodies to create cholesterol.
The most powerful driver of cholesterol production?
Believe it or not, it’s sugar!
When I say sugar, I mean added sugars and simple carbohydrates that can be rapidly turned into sugar within
our bodies. Think not only sweets (like cakes and cookies, candies and other desserts), but other foods
containing or made from refined grains – like white rice, breads, bagels and pasta.
All carbohydrates are absorbed as sugar. And when blood sugar levels go up (like after eating a bagel), the body
responds by releasing insulin. Insulin is a vital hormone that makes sure sugar is stored in our bodies for use
between meals. But it doesn’t just cause sugar to be stored. It shifts our bodies into storage mode in general.
And what’s the storage form of cholesterol? LDL, bad cholesterol. If insulin levels go up, LDL goes up.
What’s the non-storage form of cholesterol? HDL, good cholesterol. If insulin levels go up, HDL goes down.
And what if you’ve stored all the sugar you can and there’s still excess circulating in your blood stream?
Insulin helps turn that sugar into fat. The result? Triglyceride levels go up.
Some of the worst cholesterol profiles I’ve seen have been in people who eat a low-fat, low-cholesterol diet
but don’t pay attention to the amount, or source, of sugar they’re consuming. Instead of eating fruits and
vegetables and whole grains, they’re eating fat free popcorn, and low cholesterol bread, pasta, and low fat
But to be clear – sugar that occurs naturally, like in fruits – has a very different effect on our biochemistries.
Sugar that comes in the form of a whole food (like an apple) is absorbed slowly because it takes more time to
digest an apple, and this helps insulin levels to stay steadier. Note that I’m talking about a whole apple –
not apple sauce or apple juice (which is digested more quickly, losing some of the positive effect on your
biochemistry). So, when eating carbohydrates, stick as close as you can to the original form
(whole foods and grains). It’ll help you keep your insulin levels – and your cholesterol – in check."
