A study published in August in BMJ Ope n found that cutting back on sugar may save you money, as the aforementioned diseases are associated with high medical bills. None of this suggests all sugar is bad. But the sugars found in a can of cola are not the same as those in a cup of fresh berries. Natural sugars are the ones found in whole, unprocessed foods — such as the fructose in bananas or berries , or lactose in a glass of skim milk, says Vanessa Voltolina, RDN , a clinical dietitian in Westchester, New York.
And the lactose in milk comes with a healthy serving of protein that provides sustained energy, so you feel full longer than after a sugar-packed soda. Added sugars , like the ones in doughnuts and soda, are the ones to be more concerned about. Put simply, added sugar is any sugar that gets added to a food — either by you, a chef, or a food manufacturer — before it goes in your mouth, notes the U.
Added sugars include the high fructose corn syrup lurking in some ketchups and breads, as well as the honey or agave you might add to a mug of tea or smoothie. Because they don't necessarily come packaged with other good-for-you nutrients, like protein and fiber, our bodies digest them more quickly, which can cause a rapid increase in blood glucose sugar.
And over time having consistently high blood glucose contributes to health problems such as obesity , type 2 diabetes , and heart disease , according to a study publishedin the journal JAMA Internal Medicine. The high amounts of refined and added sugars in snack foods, sweets, and sodas have been linked with weight gain and the development of obesity in the United States, as they tend to be calorie dense with none of the nutritive benefits, says Voltolina. These types of sugars can cause rapid increases in blood sugar, which may increase the risk of insulin resistance and eventually type 2 diabetes.
Extra sugar may also increase risk of developing nonalcoholic fatty liver disease , as well as increased triglyceride levels , which may contribute to cardiovascular disease. In a statement published in February in the journal Circulation , the American Heart Association AHA linked high intakes of added sugars with heightened rates of obesity and heart disease.
To avoid these risks, the Dietary Guidelines for Americans — recommends limiting added sugar to less than 10 percent of your daily calories. The AHA recommends women consume no more than 6 teaspoons tsp of added sugar daily 25 grams [g] or about calories , and that men should limit their added sugar intake to 9 tsp or less 36 g or about calories.
For instance, are some types of sugar healthier than others? And will cutting it out really put you on the fast track to losing weight, easing acne, staving off mood swings, or any other health woes? Turns out, the answers might not be what you think. But what experts really mean is that we should be eating less added sugar. Added sugar is different than the sugar that occurs naturally in some foods, like fruit or milk. The takeaway? Sources of added sugar — desserts, sugary drinks, or packaged foods — are the things you need to keep an eye on.
To your body, all sources of sugar are the same. The digestive tract breaks down all sources of sugar into simple sugars called monosaccharides. And all of these sugars deliver 4 calories per gram, so they all have the same impact on your weight. Different health organizations have different recommendations for the amount of sugar you should limit yourself per day.
The U. Dietary Guidelines say that an adult eating 2, calories per day should have less than But the American Heart Association says women should have less than 6 teaspoons 25 grams , and men should have less than 9 teaspoons 36 grams per day.
So having less is better, says Fear. A whopping 75 percent of Americans eat more sugar than they should, according to the U. Dietary Guidelines. Try logging your food intake in a food-tracking app for a few days. Instead of swearing off your favorite sweet treats, try having smaller portions.
Keep an eye on packaged foods, too. Things like bread, flavored yogurt, cereal, and even tomato sauce can all have more added sugar than you might expect.
An American Journal of Clinical Nutrition study that followed more than , adults for over a decade found that added sugar consumption was not linked to an increased risk for death. The study authors found that removing sugar from the diet reversed leptin resistance.
Another study from found that sugary drinks could be a particular problem for leptin resistance. It is important to note that sugar does not cause weight gain and obesity by itself. Sugar is one of several causes. Being overweight or obese is the result of a complex interaction between diet, physical activity, genetics, and social and environmental factors.
However, limiting the amount of sugar in a diet is one of the simplest ways to prevent weight gain. There is a link between consuming sugary drinks and developing type 2 diabetes. It is not true that sugar causes diabetes. A high-calorie diet of any kind can lead to type 2 diabetes.
However, in most cases, diets high in sugar are high in calories. This can increase the risk of diabetes. A meta-analysis of data from , people found that those with a high consumption of sugary drinks had a 26 percent greater risk of type 2 diabetes than those with a low consumption. The American Diabetes Association recommend avoiding sugary drinks to prevent type 2 diabetes. After eating sugar, bacteria in the mouth form a thin layer of plaque over the teeth.
These bacteria react with the sugars present in foods and drinks. This reaction triggers the release of an acid that damages teeth. It is possible for the body to repair some of this damage itself. Over time, however, a diet high in sugar will cause lasting damage.
This can lead to tooth cavities. Cavities are permeant holes that form on teeth. Limiting the intake of foods high in sugar is one effective way to prevent tooth cavities.
High-sugar diets may increase the risk of heart disease. The results of a year study suggest that people with a lot of added sugar in their diet are significantly more likely to die from heart disease than people with minimal amounts of added sugar in their diet. Again, research suggests that sugary drinks may be particularly problematic for increasing the risk of heart disease. This association may be because sugary drinks are high in calories, do not affect hunger, and provide an insufficient amount of energy.
Although there is a clear link, more research will be necessary to better understand the relationship between sugar and heart disease. Added sugars can appear in many surprising products. Checking the contents of food before buying it is one way to avoid added sugar. However, some food labels make it difficult to tell whether they contain added sugar, as there are many different names for it.
