Dirty Keto Ingredient

What is Aspartame?

Aspartame is a synthetic sugar-free, low-calorie sweetener. Aspartame can be found in (or referred to as) Splenda, Sweet n’ Low, Equal, sucralose, saccharin, and NutraSweet.

Keto Status?



While phenylalanine is recognized as being safe in whole food products by the Food and Drug Administration (FDA), it can be toxic in large doses — which is the case with diet soda. Because phenylalanine is chemically bound in aspartame, it can be absorbed immediately. Unfortunately, the third chemical compound in aspartame, methanol, is easily converted to “free methanol” in hot temperatures. Once in this state, free methanol converts to formaldehyde. Formaldehyde is a carcinogen that has the ability to cross the blood-brain barrier, which is a filter of capillaries that carry blood to the brain and spinal cord.

Possible Side Effects From Ingesting Aspartame?

Depression, Anxiety, Fibromyalgia, Epilepsy, Alzheimer’s Disease, Diabetes, Parkinson’s Disease

I Heart Keto Mart Rating Guide

I Heart Keto Mart rates all ingredients through a “keto diet” & “low carb diet” lens. As an example, peas would be rated as “Acceptable” on a non-keto healthy diet; however, due to their carbohydrate level, we rate them “Objectionable”. We also rate all sweeteners that typically cause a rise in blood sugar and insulin levels as “Objectionable”. If you prefer a natural sweetener, like honey, over a sugar alcohol like erythritol, you may not agree with our “Objectionable” rating. I Heart Keto Mart rates all ingredients based first and foremost for those that have a sugar/carbohydrate addiction. Ingredients are rated for those who must moderate if not completely abstain from any sugars. If you have questions about this, please refer to this article: Why Some Whole Foods Are Not Keto Friendly


I Heart Keto Mart is not a health care provider. We are an online keto educational site that shares keto approved products and low carb products and defines and rates their ingredients. I Heart Keto Mart’s hope is that our viewers will educate themselves on “all things ingredients” so they can easily identify keto approved ingredients and eliminate or greatly restrict unacceptable keto ingredients. I Heart Keto Mart is the best online keto store and online low carb store with 1000s of products and an informative blog that shares keto articles and keto recipes, interviews keto coaches and keto product manufacturers and so much more.  We are keto affiliates and each of the keto approved products we rate is linked to the vendor’s site where the product may be purchased. I Heart Keto Mart may earn a small commission from these sales. Amazon is one of these affiliates.
