The glycemic index provides a scientifically valid fascinating way of evaluating the type of carbohydrates we should prefer to consume. It makes an estimation of how well these carbohydrates enter the bloodstream. And in so doing, offers a way to approach a meal in a way that is both nutritionally valuable and prevents hunger pangs. This is of course one way to avoid overeating. And it’s a perfect way for parents trying and curbing their children’s desire to eat unhealthy foods between meals.
The glycemic index categorizes the carbohydrates as being a high, medium or low glycemic index. Those foods that have a low or medium glycemic index should be eaten more as compared to those with a high glycemic index. Foods with a low glycemic index enter the bloodstream more slowly and therefore do not increase blood sugar levels like foods with a high glycemic index.
So what do you mean by carbohydrate? All foods or sugars that are broken down into sugar, are carbohydrates. This constitutes regular sugar, maltose (found in malt which is often used to flavor cereals), fructose (in fruit), lactose (found in milk and similar products like yogurt), glucose (often used in sports drinks), all types of starches, and legumes, such as lentils and peas (although these also contain protein).
Fruits are considered to have a low GI (but fruit juices are not). The recent research has found there can be a link between an obesity and fructose. The corn syrup, which is a refined and concentrated form of fructose was the kind of fructose that was studied. It also lacks the beneficial fiber, antioxidants, and other phytochemicals that fruits have. This was also preliminary research done on an animal model, so it may not be valid for human beings. Researchers at the University of Florida have found that fructose can make people think they are hungrier than they should be. And when these researchers interrupted the way fructose was metabolized, the rats they worked upon didn’t gain weight, even after eating the fructose.
This isn’t the first research to suggest that fructose may be linked to a propensity to gain weight, more than other types of food. A study conducted at the University of Cincinnati found that consuming fructose (high fructose corn syrup) resulted in greater fat storage. They say the body treats fructose differently from other types of sugars, but again, it is not clear whether this is possibly alleviated by the lower concentration of fructose in the fruit compared to the corn syrup used. in the study.
Research from the University of Florida revealed that there are greater levels of uric acid in the blood after the consumption of fructose. This uric acid surge affects insulin, blocking it. Insulin does the task of regulating the way our cells store and use fat. If uric acid levels are very high, symptoms of metabolic syndrome may develop. These symptoms include high cholesterol, high blood pressure and heavy weight gain. What can worry people is that fructose is used in many carbonated drinks, so if you drink a lot of soda it will be quite easy to increase uric acid levels in the blood frequently. Metabolic syndrome is also a precursor to type 2 diabetes.
Signs of metabolic syndrome include fat on the abdomen, so the waist looks as big as the hips or wider. There are usually lower amounts of the right kind of cholesterol in the blood and high levels of triglycerides which make the blood sticky. Metabolic syndrome is connected with the way the body reacts to insulin so that there are higher levels of glucose in the blood.
