5 Food Additives That Harm Your Brain

These common food additives are neurotoxins that can alter brain chemistry, memory, and more. These are easy to avoid and there are healthy alternatives.

surprised women eating popcornThe Food and Drug Administration allows 3,000 food additives to be used in the US food supply. (1)

When you get down to reading food labels, it gets confusing.

Not all additives are unhealthy.

You will find everyday items on the list like salt, vitamin C, and acetic acid (vinegar).

You’ll also find long-winded names like Eleutherococcus senticosus which sounds suspicious, but is actually the healthy herb Siberian ginseng.

And some of the worst health offenders are not required to be put on food labels!

I’ve highlighted a handful of worst additives that are harmful to the brain.

These are highly suspected of causing brain fog, headaches, anxiety, brain tumors, and even Alzheimer’s.

Here is my “Top 5 Hit List” that have no place in a brain-healthy diet, plus easy tips to minimize your exposure.


diet sodaThis artificial sweetener is bad news any way you look at it.

Currently, there are 92 categories of complaints filed against aspartame with the FDA. (2)

And ironically, it is highly suspected of making people who use it fatter!

Original studies were falsified to hide the fact that animals fed aspartame developed seizures and brain tumors, but the FDA approved it anyway. (3)

The FDA has a history of caring more about big business than your well-being.

Aspartame is made up of three brain-damaging chemicals — aspartic acid, phenylalanine, and methanol.

  • Aspartic acid elevates levels of aspartate and glutamate which are brain neurotransmitters. Aspartate and glutamate are “excitotoxins,” meaning that in high amounts they “excite” or stimulate brain cells to death.
  • Phenylalanine is an amino acid normally found in the brain. Ingesting aspartame can lead to excess levels of phenylalanine in the brain which disturbs the normal balance of an important brain chemical, serotonin.
  • Methanol is wood alcohol, the kind of alcohol that is extremely poisonous.

Formerly known as Nutrasweet, but now called AminoSweet, this is one of the easiest brain-damaging chemicals to avoid since it is clearly labeled.

The most common sources of aspartame include diet sodas, any product that says sugar-free, and those little blue packages that go by the brand names Equal or NutraSweet.

The FDA recently approved a new high-intensity sweetener, Advantame. 

“High-intensity” (not “artificial” sweetener) is now the preferred industry term.

It’s made from aspartame plus the artificial flavor vanillin. 

The purported benefit to consumers is that it’s 20,000 times sweeter than sugar.

(By comparison, aspartame, sucralose and saccharin range from 200 to 700 times sweeter than table sugar.) 


While the affects of aspartame have been well-publicized, those of the artificial sweetener sucralose are not as well known.

Sucralose is marketed as Splenda whose ads say “made from sugar so it tastes like sugar.”

woman with headacheWhat the ads don’t tell you is that sucralose is sugar bonded to chlorine, making it a toxic chlorocarbon.

And that there’s a long list of common neurological side effects including headaches, migraines, dizziness, brain fog, anxiety, depression, and tinnitus. (4)

Another side effect is weight gain which rather defeats the purpose.

Sucralose prevents nutrient absorption and reduces the amount of good bacteria in your intestines by 50%. (5)

This leads to an overabundance of bad bacteria which has numerous negative effects on your brain including damage to the hippocampus, the part of the brain where memories are stored.

Stop drinking diet soda or eating foods with this or any other artificial sweetener.

You’d probably be better off going back to sugar!

My favorite healthy sweetener is stevia.

This naturally sweet herb can be used to sweeten foods and drinks with zero calories, naturally.


Americans love their popcorn, munching down 17.3 billion quarts of popped corn each year! (6)

But home-popped microwave popcorn usually contains butter flavoring with the additive diacetyl.

It’s already established that this chemical causes a serious condition called “microwave popcorn lung.”

Diacetyl is able to cross the blood-brain barrier, a defense which prevents harmful substances from entering the brain.

It causes beta-amyloid clumping which is a significant indicator of Alzheimer’s. (7)

surprised women eating popcornYou won’t see the word diacetyl on the label, but if you see “artificial butter flavor” or “natural flavors” on the label, assume the product contains diacetyl.

I’m as bummed about this as you are. But you can eat popcorn safely.

The best way to get healthy popcorn is to pop your own.

It’s fast, fun, and highly economical.

Kids of all ages will get a kick of out making popcorn the old-fashioned way.

If you like butter flavor, just use the real thing.

Turns out there is nothing wrong with using a little butter, anyway.

Butter is a particularly good source of vitamin A and the fatty acid butyrate.

Butyrate reduces chronic inflammation and counters neurodegenerative disorders like Alzheimer’s and Parkinson’s. (8, 9)

Monosodium Glutamate

Monosodium glutamate, usually referred to simply as MSG, is ubiquitous in processed foods.

It breaks down in the body into glutamate, a known excitotoxin — a substance that literally stimulates brain cells to death!

A truly alarming thing about MSG is that it is in just about everything, yet it is not required to be on labels. (10)

This makes it very difficult to avoid.

It is required to be listed on a label only if it’s 100% pure MSG.

Spices, flavorings, and natural flavorings can all contain up to 99% MSG with no mention on the label!

Generally the saltier the food, the more MSG it will have, with worst offenders including canned soups, snacks, and ramen noodles.

And don’t think that shopping at a health food store will protect you.

Health food items are not immune, especially refined soy products like veggie burgers.

If you’ve ever felt weird after a Chinese restaurant meal, you’ve probably experienced MSG-induced “Chinese restaurant syndrome.”

Many people get headaches, feel dizzy, or get flushed after eating just one meal containing MSG.

Larger amounts of MSG cause arterial dilatation, migraines, upset stomach, fuzzy thinking, diarrhea, heart irregularities, asthma, and mood swings. (11)

Top MSG Sources

Here are some ingredients to watch out for that always contain MSG: (12)

• Hydrolyzed vegetable protein
• Hydrolyzed plant protein
• Hydrolyzed protein
• Plant protein extract
• Calcium caseinate
• Sodium caseinate
• Yeast extract
• Textured protein
• Autolyzed yeast

ramen noodle explosionThese ingredients may contain MSG:

• Malt extract
• Malt flavoring
• Bouillon
• Broth
• Stock
• Flavoring
• Natural flavoring
• Beef flavoring
• Chicken flavoring
• Seasoning
• Spices

Another major source of MSG is fast food restaurants. MSGTruth.org has a list of the worst offenders with KFC restaurants at the top of the list.

Even their salads and green beans contain MSG!


Aluminum is an additive in baking powder and anti-caking agents, but it is used as much more than just a food ingredient.

It is the most abundant metal in the the earth’s crust so is hard to avoid.

It’s in drinking water, antacids, deodorant, cans, foil, and is commonly used in cookware.

Aluminum is suspected of contributing to Alzheimer’s.

In the 1970′s, autopsies revealed that people that had Alzheimer’s had a larger than normal concentration of aluminum in the brain.

This understandably began a scare that aluminum was the cause of Alzheimer’s.

woman cookingMany people consequently stopped using aluminum cookware.

This soft metal leeches into food especially when cooking acidic foods like tomato, lemon, or vinegar.

Stainless steel is the better cookware choice.

It is more durable, scratch-resistant, and less reactive than aluminum.

It’s easier to keep looking good for the long haul, too.

You can also find aluminum-free deodorants, baking powder and antacids.

You can cook on parchment paper instead of foil. But is all this necessary?

Scientific proof can come slowly.

It’s been 40 years since the aluminum-Alzheimer’s correlation was made, but science has still not determined for certain whether ingesting aluminum contributes to this disease for sure. (13)

But since it is a known neurotoxin, it only makes sense to minimize your exposure.

Avoiding these five chemicals is not that difficult.

There are healthy alternatives, so you can reduce your exposure with little effort.

Taking action will help you reduce exposure to brain toxins, a key factor in keeping your brain mentally sharp for a lifetime.

Subject: The #1 nutrient every brain needs

You've probably heard that fish is brain food. That's because it's the main dietary source of omega-3 fats, essential building blocks of every cell in your brain.

But unless you eat wild-caught, oily fish like salmon or sardines EVERY day, you're not getting the omega-3s you need.

One solution is to take a fish oil supplement. But only around 10% of the fish oil you take is absorbed.

Some people take krill oil instead. But it's low in DHA, the omega-3 your brain really thrives on.

Here's a solution we found to this dilemma:
