Glycemic Index Deception Finally Understood

A new study shows that diets based on the glycemic index, like the South Beach Diet, do not effectively control blood sugar levels.

The glycemic index, which measures how quickly carbohydrates convert to sugar in your blood, has never been accepted by many dieticians.

This study, which examined food questionnaires from more than 1,000 people over the course of five years, did not find any link between the glycemic index of foods and the blood-sugar levels of participants.

Previous, smaller studies have had different results, including one that seemed to show that a low-glycemic diet lowered risk of heart disease. Supporters of the index claim that foods lower on the index make a person feel full longer and reduce cravings, helping with weight loss.

What Are GMOs?

From April 19th through April 25th we launch GMO Awareness Week. We set aside an entire week dedicated to providing you with information on GMOs and labeling initiatives.

GMOs are a product of genetic engineering, meaning their genetic makeup has been altered to induce a variety of “unique” traits to crops, such as making them drought-resistant or giving them “more nutrients.” GMO proponents claim that genetic engineering is “safe and beneficial,” and that it advances the agricultural industry. They also say that GMOs help ensure the global food supply and sustainability. But is there any truth to these claims? I believe not. For years, I've stated the belief that GMOs pose one of the greatest threats to life on the planet. Genetic engineering is NOT the safe and beneficial technology that it is touted to be.

Help Support GMO Labeling

The Grocery Manufacturers Association (GMA)—Monsanto’s Evil Twin—is pulling out all the stops to keep you in the dark about what’s in your food. For nearly two decades, Monsanto and corporate agribusiness have exercised near-dictatorial control over American agriculture. For example, Monsanto has made many claims that glyphosate in Roundup is harmless to animals and humans. However, recently the World Health Organization (WHO) had their research team test glyphosate and have labeled it a probable carcinogen.

Public opinion around the biotech industry's contamination of our food supply and destruction of our environment has reached the tipping point. We're fighting back. That's why I was the first to push for GMO labeling. I donated a significant sum to the first ballot initiative in California in 2012, which inspired others to donate to the campaign as well. We technically "lost the vote, but we are winning the war, as these labeling initiatives have raised a considerable amount of public awareness.

The insanity has gone far enough, which is why I encourage you to boycott every single product owned by members of the GMA, including natural and organic brands. More than 80 percent of our support comes from individual consumers like you, who understand that real change comes from the grassroots.

Thankfully, we have organizations like the Organic Consumers Association (OCA) to fight back against these junk food manufacturers, pesticide producers, and corporate giants.

Together, Let's Help OCA Get The Funding They Deserve

Let’s Help OCA get the funding it deserves. I have found very few organizations who are as effective and efficient as OCA. It’s a public interest organization dedicated to promoting health justice and sustainability. A central focus of the OCA is building a healthy, equitable, and sustainable system of food production and consumption. That's why I'm proud to announce I will be matching donations up to $250,000 this week.

Please make a donation to help OCA fight for GMO labeling.

Dr. Mercola's Comments:

Many have long advocated the use of the glycemic index as a useful tool to help you select foods that would have a minimal effect on your blood sugar.

The underlying premise, that some foods can seriously raise your blood sugar and as a result cause harm and damage in your body, is true. The main problem is that the glycemic index is not a valid tool to use to determine which foods will do that for you.

The glycemic index values have far too many exceptions to be consistently useful. A classic example is fructose, which has a very low glycemic index yet has been clearly established as a major reason why many people are overweight. This new data clearly supports my assertion that you should avoid using the glycemic index to select your foods.

The fact is, numerous factors play a role in how a specific food will affect your blood sugar. The glycemic index doesn't, for example, measure how a food, or a specific ingredient, affects you over time.

Moreover, it fails to take into account the harm chemicals like sucralose, sorbitol and refined fructose contained in supposedly low-GI foods do to your body; they convert directly into triglycerides and adipose tissue instead of blood glucose, accelerating obesity, diabetes, hypoglycemia and cardiovascular disease.

Rather than using the glycemic index, you would be better off using more reliable means. This is not hard, folks.

If you have diseases that are clearly worsened by high insulin levels such as:

  • High blood pressure
  • Excess weight
  • High cholesterol levels
  • Diabetes

    Then you should severely restrict all your grains and sugars until these problems normalize. No complex tables are required to reach this conclusion, just common sense. You can fine-tune the program by applying nutritional typing principles, as some people may need far more vegetable carbs than others once the grains and sugars are removed.
