What In The World Is The Glycemic Index And What Are Inflammatory Foods
We all know a little about food. So many people come to us saying they already know everything about diet and nutrition, they just don't listen to themselves.
I disagree. I think there's a lot of information out there and it's confusing. They know how to count calories and try to avoid fat and its not working. If it did, everyone who switched from Coke to Diet Coke would be losing weight.
Calories are something I won't have anyone count, and instead of looking at fat content, I have people instead look at the source of the fat (meaning where did the fat come from and what kind of fat is it).
So what is the Glycemic Index and why is it important?
It's a way to measure how quickly blood sugar levels rise after eating a particular type of food. How quickly food breaks down and gets into your bloodstream and raises your blood sugar levels is more important than calories.
You can have 2 foods, food A has higher calories than food B, but food B has a higher GI. According to this index, food B even with the lesser calories would be worse off for you. Not just in health but you will most likely gain more weight from it as well. High GI has also been related to many diseases.
Foods high in GI also cause a lot of inflammation. Inflammation means irritation of the tissue within the body that causes changes in the tissue and also release of substances in the tissue. Common symptoms we are all familiar with is swelling, redness, and heat sensation. Foods that cause a lot of inflammation are typically foods made from corn, soy, processed grains, and sugar. Which from Americans on the standard diet or a form of vegetarian diet still subsidize most of their daily meals with.
So there are some superficial differences with a lot of diets today, but most of them are bad all in the same ways.
Certain foods cause a lot of inflammation and according to David Servan-Schreiber, it is the leading cause of cancer according to his book Anti-Cancer: A New Way Of Life.
This is also why omega-3 fatty acids are all the rage, flax seeds, chia seeds, raw vegetables, super foods, juicing, and so many other foods as well fit into this category.
As far as weight gain and trying to lose weight goes, then looking at fat and counting calories then becomes an inefficient way to get where you need to go. Weight loss and gain are more the functions of how quickly food hits your blood stream, how quickly blood sugar levels rise, if your tissues are being inflamed by your food, and how it all ultimately affects your hormones.
So now you know.
