It turns out that artificial sweeteners alter the gut microbiome, specifically the duodenum (the first part of the small intestine after the stomach). And not in a good way.

The gut microbiome is the community of microbes (bacteria, fungi, viruses) that lives in the small intestine - and it looks different in persons who use artificial sweeteners compared to persons who don't.

Researchers found that artificial sweeteners lowered microbial diversity (not good), and increased numbers of harmful bacteria in the duodenum. They also alter inflammation markers that circulate in the blood in a negative way. The use of non-aspartame artificial sweeteners (sucralose, saccharin, stevia) had slightly different effects than aspartame, but both overall had negative effects (when compared to gut microbiomes of persons not ingesting artificial sweeteners in their diet).

You may think that artificial sweeteners can help you lose some weight, but a new study finds they are no good for your gut's microbiome. ...continue reading "Artificial Sweeteners Alter the Gut Microbiome"

Another recent study found that consuming artificial sweeteners do harm. In August a study found that artificial sweeteners alter both the oral and gut microbiomes in a negative way. Other earlier studies found an association with high blood pressure, inflammation, weight gain, vascular dysfunction, and increased risk of cancer.

Now, a large study found that high consumption of artificial sweeteners is associated with increased risk of heart disease (cardiovascular disease), including heart attacks and strokes (cerebrovascular events).

What is high consumption of artificial sweetener? One individual packet of artificial sweetener or a 100 mL of diet soda is about 42.46 mg/day, while in this study high sweetener consumption is about 77.62 mg/day. So high consumption is not even 2 diet sodas or packets per day.

Bottom line: Artificial sweeteners are NOT a healthy or good alternative to sugar (or maple syrup or honey). Also, avoid high fructose corn syrup - that has its own problems. Artificial sweeteners are found in highly processed foods - try to also avoid those for your health.

Cardiovascular diseases are the leading cause of death worldwide. Avoiding sugar and instead consuming artificial sweeteners is not going to help you achieve health. But improving your overall diet will, such as eating a diet rich in whole grains, fruits, vegetables, seeds, nuts, legumes (beans).

A large study of French adults published by The BMJ today suggests a potential direct association between higher artificial sweetener consumption and increased cardiovascular disease risk, including heart attack and stroke. ...continue reading "Health Harms Associated With Artificial Sweeteners"

All of us want to have a healthy gut microbiome (the microbial community of viruses, fungi, and bacteria). For health reasons many people try to lower their intake of sugars. However, ingesting artificial or non-nutritive sweeteners such as stevia, sucralose, aspartame, or saccharin may also have an effect on the body.

A recent study in both humans and mice found that these sugar substitutes cause gut microbiome changes and had an effect on a person's glycemic response (blood sugar levels). Saccharin and sucralose significantly impaired glucose tolerance in healthy adults - it impacted their glycemic response even at doses below FDA allowances (average daily intake or ADI).

The non-nutritive sweeteners also had an effect on the oral (mouth) microbiome. Each sweetener had a different and distinct effect on both oral and gut microbiomes. And the effects varied in each person, due to everyone having a different (unique) microbiome.

Earlier studies found negative health effects from sugar substitutes (e.g., higher incidence of diabetes, higher risk of cancer, gut microbiome changes). So be cautious until more is known. One of this study's researchers suggested drinking only water.

From Medical Xpress: Non-nutritive sweeteners affect human microbiomes and can alter glycemic responses

Since the late 1800s non-nutritive sweeteners have promised to deliver all the sweetness of sugar with none of the calories. They have long been believed to have no effect on the human body, but researchers publishing in the journal Cell on August 19 challenge this notion by finding that these sugar substitutes are not inert, and, in fact, some can alter human consumers' microbiomes in a way that can change their blood sugar levels. ...continue reading "Sugar Substitutes Alter Gut Microbiome"
