Is Aspartame Safe? Aspartame Side Effects to Know

Aspartame is one of the top sugar substitutes of choice. This handy chemical compound tastes sweet, dissolves readily and is easily substituted for sugar in most sugar free, low calorie treats. It was created in the 1965 and infiltrated our food supply in the 1980s after gaining the go ahead nod from the Food and Drug Administration.

Aspartame is not the only name this sugar substitute goes by. NutraSweet is probably much more a household name than aspartame. Even so, aspartame is not usually advertised in big lettering on the label. What is much more prominent are the words ‘sugar free’ or ‘diet’. These words say almost the same thing as simply printing aspartame in bold across the front.

Aspartame held the lion’s share of the sugar substitute market for years, but in recent years is losing market share to brands like Splenda. The only way to know what you are eating or drinking for sure is to read the fine print under ingredients. But is it safe? Let's find out.

Aspartame Side Effects

Now, sugar free snacks are rampant on grocery shelves. These guilt-free treats are accepted with delight by dieters and diabetics alike. There is only one problem: aspartame is not the sweet solution it is cracked up to be.

The FDA receives thousands of complaints about the real and perceived dangers of approved foods and drugs every year. Of those thousands, roughly 80% relate directly to aspartame and its derivatives.

That’s nothing to scoff at, yet it goes one step further. The FDA keeps lists of known negative side affects for each of its approved items. The list belonging to Aspartame is comprised of over 92 documented complaints, including death.

Less dramatic possible side effects, yet still scary enough to make the average Joe put down his diet soda and walk away include: headaches, blindness in one or both eyes, damage to night vision, ringing in the ears, seizures, trouble concentrating and sluggish cognition, anxiety, insomnia and the list goes on.

One of the most ironic side effects is weight gain. Persons seeking relief from a few pesky pounds turn to aspartame laden treats to aid them in their weight loss efforts only to find themselves rewarded with even more to lose.

Sugar in large quantities is not great for your health. That is an easily acceptable fact. What might be a bit tougher to swallow is that you can’t have your cake and eat it too. Aspartame fails miserably in this effort. It is a better idea for your health to stick to sugar, but less of it. Or, try an alternative artificial sweetener with fewer issues.

A Final Note About Aspartame

While all of this may seem scary and turn you off from aspartame entirely, it's important to remember that research is not completely conclusive. Some research has found conclusive evidence to point to the danger of aspartame, while other research is less conclusive. It seems more research is needed to firmly establish the specific risks of aspartame.

Until then, it may be worthwhile to consider other artificial sweeteners. As aspartame becomes less popular, choosing a different alternative sweetener has never been easier. Splenda is a very popular artificial sweetener, and does not contain aspartame. Of course, you should still consume other artificial sweeteners in moderation.

If you still have questions or concerns about aspartame, consult with your doctor. They can provide you with all of the answers! A qualified nutritional specialist is also a good person to consult with questions about aspartame and other artificial sweeteners. Remember to only ever trust well-vetted, reputable scientific research and articles that cite such research.
