Glycemic Index and sugar on your health



You must have sugar to survive. But sugar is bad for you, right? It all depends on the way sugar is presented to your body. That’s where glycemic index comes in. Let’s look at the ways sugar heals…or kills you.

Sugar is not sugar is not sugar!

Your brain cells must have enough sugar for you to stay conscious. Your heart and muscles require sugar to be active. In fact, the basic molecule that every cell in your body absolutely must have…is sugar.

Then why all the fuss about sugar? I’ll tell you why.

Depending on the way sugar gets to your cells, it will heal you or kill you! So, you must learn about the new standard that helps measure this process. Its call glycemic index (GI). The glycemic index is a measure of how quickly 50 grams of carbohydrate in a particular food is converted to glucose (the simplest sugar molecule) in your body. Unless you go exercise shortly after eating, the higher the glycemic index of food you consume, the faster it causes all sorts of diseases.

In fact, consuming high glycemic foods has been biochemically proven to promoting obesity, diabetes, cancer, poor immune system and generalized body inflammation.

For example, since glycemic index was first described in 1981 by Jenkins,[1] it has become the new standard for diabetes management in France, United Kingdom, Australia, Canada, and New Zealand.

Now that you are getting a hint about the power of consuming sugar. Before I explain more about how the glycemic index can guide you to preventing and reversing disease, let’s look a just a few of the proven adverse effects of consuming sugar.

Sugar can do all this damage?

There are a multitude of illnesses that are caused by ingesting sugar. Let me just give you a few. First off, we know that sugar contributes to obesity.[2] Sugar can increase the systolic blood pressure.[3] Sugar spikes insulin which leads to metabolic syndrome, heart disease, and diabetes (explained more in my next article).

Moreover, sugar basically feeds cancer.[4] In fact, sugar consumption plays a key role in the development of many cancers, including:

  • pancreatic cancer in women[5]

  • stomach cancer[6]

  • biliary tract[7] and gall bladder cancer[8]

  • colon cancer[9]

  • lung cancer[10]

  • prostate cancer[11]

  • breast cancer[12]

  • small intestinal cancer[13]

  • laryngeal cancer[14]

  • rectal cancer[15]

  • kidney cancer[16]

  • liver tumors[17] and

  • endometrial cancer[18]

Have I gotten your attention? Essentially, high glycemic foods load your body with dangerous sugar, while low glycemic foods give nutrients that naturally convert to the amount of sugar your body needs. And this pathway to providing sugar to your cells makes all the difference! That’s why I want so badly to explain glycemic index in a bit more detail here.

Understand glycemic index (GI) for your health

Interestingly, GI does not take into account portion size and total amount of

carbohydrate in a meal or food type. Instead it is the measure of how quickly carbohydrate is converted to glucose in your body.

Glycemic index (GI) scores are 100 for glucose in most scales and 100 for white bread in other scales. It actually is not a measurement of calories. The GI goes beyond the simple versus complex carbohydrate classification. It actually will guide you to health.

In my next article I’ll explain which are the high GI foods, and how they cause obesity, metabolic syndrome / insulin resistance syndrome, diabetes, and heart disease. Wow, did I say sugary foods promote even heart attacks? Yes, that’s right!

To nutrient rich, low glycemic foods for health,

Michael Cutler, M.D.
