Does Eating Fruit Make You Fat?
One piece of weight loss advice many diet gurus give is to eat more fruits and vegetables and cut back on processed junk foods. Is that really good advice? Well, you know that enough of anything can make you fat. A new study is out that you may think stands that diet guru advice on its head. The brand new study, just completed at the University of Texas Medical Center came to a conclusion that could lead you to believe that eating fruit will make you fat, and fast!
The study, published in the Journal of Human Nutrition, examines eating fructose, the sugar found in fruits, and the results can have you running, screaming, from the produce aisle. Lead researcher Dr. Elizabeth Parks says her team’s findings indicate “……once you start the process of fat synthesis from fructose, it’s hard to slow it down” That sounds a bit ominous, especially if your goal is to lose fat, not start fat synthesis.
The problem with fructose arises because of how the body metabolizes it. Unlike other sugars, fructose is able to skate by some of the body’s regulation procedures. Typically sugars are processed to determine what should be done with them. Your body has 3 choices, and what it decides has a huge impact on weather or not you’ll be holding a six pack in your hand or on your belly this summer.
Your body can either use the sugars as they are eaten, use them to replace glycogen stores you may have used up during exercise, or turn them into triglycerides. The study indicates that fructose is more easily made into triglycerides than other sugars, meaning that it is already well on its way to your belly.
The double blind study examined 6 test subjects, who drank one of 3 different sugar drinks in the morning, on an empty stomach. One drink contained 100% glucose, one was a 50% / 50% mix of glucose and fructose, and the third contained a 25% / 75% mix of glucose and fructose. All six individuals did 3 separate tests, drinking a different one of the drinks each time, to weed out any differences in individual metabolism and prevent it from skewing the results.
The results of the study showed that not only did the sweet drinks work differently in the body, they also affected the way the body dealt with lunch, 4 hours later. The glucose only drink had the least amount of lipogenesis. Lipogenesis is the process your body uses to transform sugars into fat. Surprisingly, just changing to a 50/50 mix of glucose and fructose caused a massive increase in lipogenic activity. Dr. Parks stated that, because of the way the fructose was processed “…. when the next meal was eaten, the lunch fat was more likely to be stored than burned. “
Does that mean you should rush to your refrigerator and immediately throw all your nectarines, apples and pineapples into the garbage? No, far from it. Fruits are still a valuable part of a healthy diet. The study did suggest that, once again, it is high fructose corn sweetener that should be taken to the trash. It is just another nail in the HFC coffin.
Despite the corn lobby’s commercials to the contrary, it seems evidence is mounting that high fructose corn sweetener really does make you fat. So, actually take the time to read that fine print on the packaging that we call the ingredients label. If you see “high fructose corn sweetener”, put the item back down and look for a different choice, because that nectarine may not make you fat, but it sure looks like HFC can.
