Fructose is converted to glucose or stored as fat. Your body converts fructose to glucose in the liver to use it for energy. Excess fructose places a burden on your liver, which may lead to a series of metabolic problems Several studies have demonstrated the harmful effects of high fructose consumption. These include insulin resistance, type 2 diabetes, obesity, fatty liver disease and metabolic syndrome 14 , 15 , In one week study, people who drank fructose-sweetened beverages had an 8.
Another study found that while all added sugars can increase your risk of type 2 diabetes and obesity, fructose may be the most harmful Since fructose is metabolized in your liver like alcohol, some evidence suggests that it may be similarly addictive.
One study found that it activates the reward pathway in your brain, which may lead to increased sugar cravings 20 , Fructose has been linked to several negative health effects, including obesity, type 2 diabetes, insulin resistance and fatty liver disease. Consuming fructose may also increase feelings of hunger and sugar cravings.
There is no need to avoid sugars that are naturally found in whole foods, such as fruits, vegetables and dairy products.
These foods also contain nutrients, fiber and water, which counter any of their negative effects. The harmful health effects associated with sugar consumption are due to the high amount of added sugar in the typical Western diet. To put that into perspective, one ounce ml can of soda contains about 30 grams of added sugar, which is enough to push you over your daily limit When buying processed foods, always read the ingredient list carefully to look for hidden sugars.
Keep in mind that sugar can be listed by over 50 different names. The most effective way to reduce your sugar intake is to eat mostly whole and unprocessed foods. Added sugars should be limited, but there is no need to worry about those found naturally in foods.
Consuming a diet high in whole foods and low in processed foods is the best way to avoid added sugars. Your body can absorb them more easily than the disaccharide sucrose, which must be broken down first.
Fructose may have the most negative health effects, but experts agree that you should limit your intake of added sugar, regardless of the type. To ensure a healthy diet, eat whole foods whenever possible and save added sugars for the occasional special treat.
It is broken down slowly and helps to increase the absorption of minerals such as calcium, magnesium and zinc. Some people experience lactose intolerance — an inability to produce the lactase enzyme that breaks down milk. Lactose intolerance can lead to diarrheoa, bloating and other gastrointestinal symptoms.
There are two types of sugar: naturally occurring sugar like lactose in milk and added sugar, which includes table sugar sucrose as well as concentrated sources like fruit juice. This equates to approximately seven teaspoons 30g for an adult. Virtually all the fibre, phytochemical, vitamin and mineral content have been removed from white sugar sucrose. Eating too many carbohydrates, particularly simple sugars, can be harmful to blood sugar control , especially if you are insulin resistant, experience reactive hypoglycaemia or are diabetic.
Eating excess sugar can lead to weight gain, which increases the risk of heart disease and type 2 diabetes. All you need to know about sugar How much sugar should I eat?

I see tons of recipes using honey and dates as sweeteners and I WANT those to be better grams to grams than added sugar, but I have not seen the evidence. Sugar is sugar no matter where it comes from.
Your body cannot distinguish a source. A chemistry lab cannot distinguish a source. Sugar that is the monosaccharides of fructose and glucose, which is the form that sugar exists once it is in your body.
The sugar from sugar cane is identical to the sugar from honey, apples, pears, dates, HFCS. They all break down to fructose and glucose in your body and look and act identically. Added sugars are identical to natural sugars. The take home message is all sugar is identical. Just reduce your overall sugar intake for overall health benefits. I also experienced a much clearer mind and had much more energy.
I would argue that if I were to become addicted to anything, it would be healthier to go with the natural whole food approach than eat overly processed foods with added ingredients.
Bravo Colin! And keep up that attitude and determination and I promise your body will thank you for it. I was expecting something better from Harvard, I was wrong. You need to do more research. These articles are fairly close and I think its people just trying to find fault and be skeptical. At some point you have to find your source and trust it, but please pick worthy sources.
Yes apples have high fructose but the fiber controls its release and we get the benefits of the fruit while the sugar slowly enters the body and a healthy level. All we can do is our best homework, trust your doctor or find a new one!
Thanks for your Comment! I think the author is probably a smart person… therefore probably on the HFCS payroll. Everyone agrees HFCS is the cheaper option that industry wants. The industry pays these people off to pass the buck along. How they sleep at night is what I want to know? The good news, amazing news, is that the FDA made the added sugar labels.
It is actually fantastic triumph against these people. I use these labels all the time when making food choices to reduce my sugar intake. I am not alone it seems and I have noticed a trend that products are containing less and less added sugar. It used to be difficult, for example, to find peanut butter with zero added sugar.
Less so these days. Comparing 1 orange to a 16 oz glass of orange juice is very misleading. Consuming the recommended amount of orange juice with zero added sugar has been found to have no association with the development of type 2 diabetes in many literature reviews. When consumed in moderation, it is a healthy source of vitamins and flavonoids which actually help protect against cerebrovascular disease.
Considering this article has come out of Harvard, I expect better as you must be aware of the effect your publications have on the behaviour of the general public. To avoid occasional heartburn, the best solution is to change eating habits and to avoid foods that affect the esophageal valve and cause it to soften which allows food and acid to back up.
But, for a short-term relief, we take antacids, to neutralize stomach acid that is in the esophagus, and a teaspoon of sodium bicarbonate in a glass of water usually bring almost instant relief. This is amazing. Added sugar are the problems with the processed foods today.
