Research shows that Artificial Sweeteners increase blood sugar, May lead to Diabetes

Standard

The journal Nature has recently published an article that shows that artificial sweeteners increase blood sugar, and may lead to type 2 diabetes as directly as eating sugar does. The use of artificial sweeteners has been a contentious topic for decades. The new research, from the Weizmann Institute of Science in Israel, finds that differences in gut microbes may explain why some people can handle artificial sweeteners just fine while for others the sweeteners lead to blood sugar problems.

The human digestive system is home to millions of microbes, largely bacteria, that help digest food and play a major role in one’s health.

Eran Elinav, who studies the link between an individual’s immune system, gut microbes and health at the Weizmann Institute admitted that his research has soured him on sweetening the coffee he needs to get through his day.  “I’ve consumed very large amounts of coffee and extensively used sweeteners, thinking that they were at least not harmful and perhaps even beneficial,” Elinav said at a telephone news conference Tuesday. “Given the surprising result we got in our study, I made a decision to stop using artificial sweeteners.”

Artificial sweeteners are not digested, so it was assumed that there would be no way for them to lead to diabetes. Microbes commonly found in the human gut, however, seem to be affected by these indigestible sugars.  In a series of experiments in mice and people, the researchers examined the interaction between gut microbes and consumption of the sweeteners aspartame (found in NutraSweet and Equal), sucralose (found in Splenda) and saccharine (found in Sweet’n Low). Depending on the types of microbes they had in their intestines, some people and mice saw a two to fourfold increase in blood sugars after consuming the artificial sweeteners for just a short time. These increased levels of blood sugar can easily lead to diabetes over time.

Researchers began by testing the three widely used sweeteners in mice. Some mice got one of the artificial sweeteners in their water, and others got sugar water or just water. After 11 weeks, researchers gave all the mice a dose of sugar and monitored the response in their blood sugar levels.

“The magnitude of the differences were not just a few percentages. These were very dramatic differences,” said Eran Segal, a study co-author who is a computational biologist at the Weizmann Institute.

A diet study of 400 people found that those who consumed the most artificial sweeteners were more likely to have problems controlling blood sugar.

In another part of the study, researchers gave seven individuals a high dose of saccharin, 5 milligrams per kilogram of body weight, the Food and Drug Administration’s maximum daily intake, for 6 consecutive days.  Four of these individuals also began showing signs of glucose intolerance.  The researchers report suggested that artificial sweeteners “may have directly contributed to enhancing the exact [diabetes] epidemic that they themselves were intended to fight.”

So next time you want a diet drink reach for a water and add a squeeze of fresh lemon or lime.

Hidden Health Risks in Beauty Products

Standard

Europe’s regulatory system bans close to 1,400 ingredients in cosmetic products, including carcinogens like parabens and toxic chemicals that can cause reproductive and developmental-health risks. The United States bans 11. Here are the top few on the watch list from Consumer Reports, found in their publication, ShopSmart.

  • Formaldehyde releasers and 1,4 dioxane, both possible carcinogens, may be found in some anti-wrinkle creams, mascaras, makeup removers, hair conditioners and body washes. They can contain preservatives that release formaldehyde over time when mixed with water. Avoid products with quaternium-15 and DMDM hydantoin listed as ingredients.
  • Phthalates. Diethyl phthalate (DEP), which is found in fragrance, and dibutyl phthalate (DBP), a plasticizer in nail polish, have both been deemed toxic by the Federal Hazardous Substances Act. Steer clear of products with ingredients lists that include the word “fragrance,” and look for nail polishes that do not have DEP or DBP in the ingredients lists.
  • Triclosan and Triclocarban. Found in hand and body washes, deodorants, toothpastes, and some cosmetics, these antibacterial agents can affect reproductive growth and developmental systems. Choose products that do not list triclosan or triclocarban on their ingredients list.

 

Solution: Lisa Freeman, the editor of Consumer Report’s ShopSmart Magazine, says the easiest way to avoid phthalates, formaldehyde, nanomaterials and other potentially harmful chemicals is to shop for health and beauty aids at Whole Foods Market.Toxic Chemicals

Meaningful Labels

The terms “natural,” “dermatologist tested,” and “hypoallergenic” aren’t meaningful because they aren’t independently verified. Below are some examples of terms and seals that are legit according to ShopSmart’s safety experts:

  • USDA Organic. Requires that at least 95 percent of the ingredients be organically grown and prohibits the use of all potentially harmful synthetic ingredients.
  • Natural Products Association Certified (NPA) and Design for the Environment (DfE).Standards include bans on triclosan, phthalates, formaldehyde, and formaldehyde releasers.
  • Non-GMO Project Verified. The product contains no genetically engineered ingredients. 

Beauty Product Shopping Apps

When shopping for beauty products, ShopSmart recommends using these free apps to evaluate ingredients and help narrow down choices: Think Dirty, Skin Deep Cosmetics, and GoodGuide.
