Artificial Sweeteners: Keto Friend Or Foe?

Artificial sweeteners are a hot topic in the keto community. While they are sugar and calorie-free, some artificial sweeteners can still affect your blood sugar and insulin levels. Sucralose, for example, is often used in baked goods and drinks, but it has been found to produce harmful compounds when exposed to high temperatures. Other artificial sweeteners such as aspartame and saccharin have been linked to health issues including headaches, dizziness, and in some cases, cancer. Natural sweeteners like stevia, monk fruit, and erythritol are considered safer alternatives as they have little to no impact on blood sugar and insulin levels. However, even natural sweeteners should be consumed in moderation as they can stimulate sugar cravings and lead to increased calorie consumption.

Natural sweeteners like honey and maple syrup are not keto-friendly

Honey is 100% carbohydrate, with one tablespoon containing 17.2 grams of sugar. This makes it very similar to refined sugars like sucrose and high-fructose corn syrup, which have been linked to obesity, type 2 diabetes, heart disease, cancer, and other degenerative conditions. Honey is also high in calories, which can interfere with weight loss goals.

Maple syrup is also full of antioxidants and oligosaccharides, which have been shown to improve blood glucose regulation in rats. However, it is still just glucose and fructose, and high intakes of these refined sugars can lead to health problems. Maple syrup is also high in calories and carbs, which are not suitable for a keto diet as they can interrupt ketosis.

Both honey and maple syrup are considered healthier alternatives to refined sugar and are often marketed as such. While they do contain some beneficial compounds, the high levels of glucose and fructose mean they are not suitable for a keto diet.

Instead, those on a keto diet can opt for keto-friendly sweeteners like stevia, sucralose, erythritol, xylitol, monk fruit, and yacon syrup. These sweeteners are low in carbs and calories and can be used to sweeten beverages, baked goods, sauces, and dressings without derailing ketosis.

Artificial sweeteners like saccharin, sucralose, aspartame, etc. don't raise blood sugar levels

Artificial sweeteners are a great alternative to sugar for those on a keto diet. They can be used to sweeten everything from drinks to desserts without compromising the health benefits of the diet. Sucralose, saccharin, aspartame, and other artificial sweeteners are popular choices for those following a keto diet as they are calorie-free and do not affect blood glucose levels.

Sucralose, for example, is an artificial sweetener that passes through the body undigested, providing no calories or carbs. It is commonly found in the market under the brand name Splenda. While sucralose itself is calorie-free, Splenda contains other ingredients that contribute a small number of calories and carbs. It is important to check the labels of such products to ensure they align with your dietary needs.

Aspartame is another commonly used artificial sweetener. It is the only artificial sweetener that is considered a nutritive sweetener as it contains more than 2% calories. However, it still has a minimal impact on blood sugar levels.

Saccharin, often found under brand names like Sweet'N Low and Sweet Twin, is another artificial sweetener that can be used to sweeten foods and beverages. It does not enter the bloodstream and does not directly affect blood sugar levels.

These artificial sweeteners can be a great tool for managing blood sugar, especially for those with diabetes or prediabetes. Mag Ayyad, a dietitian specializing in weight management, states that artificial sweeteners are "definitely the lesser of two evils" when compared to regular sugar. By switching from sugar to artificial sweeteners, you can significantly impact blood sugar levels and work towards improving your overall health profile.

It is worth noting that while artificial sweeteners themselves do not raise blood sugar levels, they are often added to foods that contain other ingredients like fat, which can still cause a spike in blood sugar. Therefore, it is important to read nutrition labels and be mindful of the total calorie and nutrient content of the product, rather than solely relying on marketing labels like "No Sugar" or "Keto-Friendly."

In conclusion, artificial sweeteners like saccharin, sucralose, and aspartame are excellent options for those on a keto diet as they do not raise blood sugar levels. They can help manage blood sugar spikes, especially for those with diabetes or prediabetes, and are generally considered safe for consumption. However, it is always recommended to consume them in moderation and be mindful of the other ingredients in the products you are consuming.

Sugar alcohols like erythritol, xylitol, and maltitol can cause digestive issues

Sugar alcohols are a category of sweet carbohydrates that are partially resistant to digestion. They are like hybrids of sugar molecules and alcohol molecules. However, these alcohol molecules will not get you drunk. The name "sugar alcohol" refers to a category of chemical compounds, not ethanol (which is the alcohol molecule that intoxicates us).

Because sugar alcohols have a similar chemical structure to sugar, they activate the sweet taste receptors on your tongue. Unlike most artificial and natural sweeteners, sugar alcohols contain calories and net carbs, just fewer than plain table sugar.

If you have irritable bowel syndrome (IBS) or an intolerance to FODMAPs, it is advisable to limit your intake of sugar alcohols or avoid them altogether.

Erythritol and stevia are good keto-friendly sweeteners

Erythritol is a naturally occurring sugar alcohol found in fruits like grapes and watermelon. It can also be found in some fermented foods like cheese and soy sauce. Erythritol has zero calories and is about 60% to 80% as sweet as table sugar. The FDA considers erythritol to be safe, and it does not cause blood sugar spikes or promote tooth decay. Erythritol might cause fewer problems than other sugar alcohols, and it is also easy on the stomach and doesn't cause bloating or gas.

Stevia is a low-carb sweetener native to South America and is found in Argentina, Brazil, and Paraguay. It is about 200-400 times sweeter than table sugar and has little to no carbohydrates. It is also generally recognized as safe (GRAS) by the FDA, making it a good alternative to table sugar in food and drinks. Stevia might lower blood sugar, which can be beneficial for people with diabetes, but it could be dangerous for those taking insulin. It may also lower blood pressure, so it is important to talk to a healthcare provider before trying stevia if you take blood pressure medication.

While Erythritol and stevia are good keto-friendly sweeteners, it is important to use them in moderation. Erythritol, for example, has a cooling effect on the tongue and might be unpleasant in large doses. Stevia also has a unique aftertaste and might not work well in large quantities, such as in baked goods. Additionally, some people worry that stevia may be an endocrine disruptor that interferes with sex hormones, although this fear is based on test tube data.

Monk fruit is a relatively new keto-friendly sweetener

The sweetness of monk fruit comes from a chemical within the fruit called mogrosides, which are antioxidants that comprise much of the fruit's sweetness. Monk fruit has zero calories and does not spike insulin. It is also generally free of side effects, although there are some suggestions that it may have anti-inflammatory benefits. Monk fruit can be used as a sugar substitute in baked recipes and beverages, although it is recommended to start with a small amount to avoid oversweetening.

Monk fruit gets its name from the Buddhist monks who would collect the melon-type fruit, dry it, and use it in herbal teas for medicinal and ceremonial purposes. It is a modern-day superfood and can be used to enhance any type of diet, including Mediterranean, ketogenic, DASH, diabetic, candida, paleo, and vegan diets. It is also a good option for those pursuing a low-sugar lifestyle. Monk fruit sweetener may help with weight loss and can be beneficial for overall health and fitness.
