Are Artificial Sweeteners Good for Me?

Updated on Aug 29, 2024 | Endocrinology, Your Health

Whether you prefer sugar substitutes in your coffee or enjoy artificially sweetened foods, you may wonder how these products affect your body, and if there are potential health risks.

David Lam, MD

In this Q&A, David Lam, MD, Medical Director of the Clinical Diabetes Institute at the Icahn School of Medicine at Mount Sinai, explains what the research says and how to use artificial sweeteners for weight loss.

What are the health benefits of using artificial sweeteners?

The only demonstrated health benefit of artificial sweeteners is they reduce your chances for developing cavities. These sweeteners have zero or very few calories, compared with sugar. However, for those who are looking to reduce their weight or control diabetes, the research is conflicting. There is some evidence that in the short term, there are some improvements in weight loss and glucose control, but the research is not definitive on whether artificial sweeteners help with weight loss in the long term.

What are the potential risks?

There are concerns about whether sugar substitutes increase your risk for cardiovascular complications and diabetes. However, for each study that shows an increased risk, another shows it’s not so defined. While the research so far is inconclusive, patients should be aware these questions exist.

One thing you do need to be wary of—the blanket terms “artificial sweeteners” and “sugar substitutes” are broad.

What are the different types of artificial sweeteners?

Sugar substitutes generally fall into three categories:

  • Synthetic sugars are made in laboratories and factories. Examples include Sweet’N Low® and Splenda®.
  • Sugar alcohols are often found in processed foods labeled as diet products. Despite the name, these products don’t contain actual alcohol. Unlike synthetic sugar, sugar alcohols can affect your blood sugar, so the marketing labels on these products (e.g., “sugar free”) may be misleading. Additionally, people who have underlying digestive problems may have a negative reaction to sugar alcohols, such as stomach upset and bowel movement changes.
  • Natural sugar substitutes, such as Stevia, are extracted from plants. These sugar substitutes are processed in laboratories and factories, but are essentially natural products, such as agave or honey.

How can I know if a food product contains sugar alcohol?

Sugar alcohols are usually found in diet products labeled “sugar free.” If you look at the food label and see ingredients ending in “ol” as in alcohol—such as sorbitol, xylitol, maltitol—it contains sugar alcohols.

Is there a way I can use artificial sweeteners for weight loss?

Artificial sweeteners are useful for weening yourself off added sugar and gradually adapting a wholefood diet. We know they are not effective long term. A doctor or dietician can guide you on how to create a long-term weight loss plan that works for you.  For example, a nutritionist can help you understand how to integrate whole fruits into your diet. While fruits contain sugar, they also contain fiber and other nutrients that are part of a wholesome diet, and can be a healthy substitute for processed snacks. Ultimately, there is no one perfect solution for weight loss. You need to weigh the pros and cons of artificial sweeteners on an individual level, and a health care professional can help you do that.

The Growing Problem of Diabetes: What Can We Do? (Part 3)

Updated on Jun 30, 2022 | Diabetes, Endocrinology

This post was written by Gerald Bernstein, MD, FACP, Director, Diabetes Management Program, Friedman Diabetes Institute at Mount Sinai Beth Israel.

In part 1 of this series, we looked at the overwhelming numbers of people with diabetes or prediabetes. In part 2, we looked at the critical role of structured education. Now, in part 3, we will look at a potential intervention.

Remember, over 40% of the US population over the age of 20 has either diabetes or prediabetes. Both are progressive stages of the same disorder and both have enormous risks attached to them. The solution to a problem of this enormity can best be approached by a partnership of private philanthropy, governmental support and institutional buy-in. (Although things may change, it does not look like there will be a federally mandated national diabetes program in the near future.) The underlying premise is that great institutions do great things.  (more…)

The Growing Problem of Diabetes — What Can We Do? (Part 2)

Updated on Jun 30, 2022 | Diabetes, Diet and Nutrition, Endocrinology

This post was written by Gerald Bernstein, MD, FACP, Director, Diabetes Management Program, Friedman Diabetes Institute at Mount Sinai Beth Israel.

It was the month of June 1959. I was in the last 30 days of my physician training internship, rotating through pediatrics. A 12-year old girl was admitted with type 1 diabetes mellitus. At that time, the only available tools for diabetes management were testing the urine for glucose and ketones. Other blood tests, including blood glucose, could take hours to perform. Insulin for injection consisted of mixed animal insulin (cows and pigs) and was much longer-acting and less predictable than the type we use today. The patient was a remarkable young woman and took things in stride.

Diabetes No Match for Tennis Champions

Updated on Jun 30, 2022 | Diabetes, Endocrinology, Health Tips

When I was in high school in the late 1940s, I lived a few blocks away from the West Side Tennis Club. This was the home of the United States Championships, which ranked with those of Australia and Wimbledon. It was a different, more amateur era for tennis — players wore all white, including sneakers, and just as white were the tennis balls — yet the play was no less intense than that of today. Back then, there were no “tie breakers,” so matches could go on for hours — a challenge for any player with type 1 diabetes (once known as juvenile diabetes). (more…)

One of today’s greatest public health issues is the growing number of people with diabetes mellitus, most commonly type 2 and most often (but not always) associated with excess weight. To appreciate the scope of the problem, it is important to understand the true nature of the disease. (more…)

Polycystic Ovary Syndrome (PCOS)

Nov 6, 2013 | Common Illness, Diabetes, Endocrinology, LGBT Health, Women's Health

Polycystic ovary syndrome, commonly known as PCOS, is one of the most common female endocrine disorders.

A syndrome is a group of signs and symptoms that occur together to characterize a particular condition. The definition of PCOS includes irregular periods, signs of excess androgenic hormones (masculine hormones) such as acne and excess hair growth, and an exclusion of other causes of an elevation of androgens. Although the name indicates the presence of cysts on the ovaries, not all women with PCOS have cysts (and not all women with ovarian cysts have PCOS). (more…)
