Dietitian says we don't need to fear aspartame

URBANA - With the new year starting this week, your mind may wander back to conflicting summer news about aspartame, an artificial sweetener found in things like diet soda, gum, ice cream, yogurt and other sugar-free foods. The World Health Organization (WHO) cited “limited evidence” of aspartame being “possibly carcinogenic to humans.”

Not so fast, responded the United States Food and Drug Administration (FDA).

“Aspartame is one of the most studied food additives in the human food supply,” the agency said. “FDA scientists do not have safety concerns when aspartame is used under the approved conditions.”

Carly Zimmer, a registered dietitian-nutritionist at OSF HealthCare, explains how we got here.

Zimmer says the agency within WHO that researches cancer has four levels of certainty that a substance can cause the disease. Group one is labeled “carcinogenic to humans.” Things like tobacco, alcohol and solar radiation are here. Group 2A is “probably carcinogenic to humans.” Group 2B is “possibly carcinogenic to humans.” And group three is “not classifiable as to its carcinogenicity to humans.” Coffee and mercury are in this group.

WHO put aspartame in group 2B along with aloe vera plant extract and traditional Asian pickled vegetables.

“That group B classification means there is a possible risk for that substance to cause cancer, not that it’s necessarily linked to cancer,” Zimmer says.

The other thing to consider: Zimmer says the FDA sets an acceptable daily intake for the six sweeteners it has approved. For aspartame, the limit is 50 milligrams per kilogram of body weight. For example, someone who is 60 kilograms (or 132 pounds) would have to consume 75 packets of aspartame (think of brand names like Equal, NutraSweet and Sugar Twin) in a day to reach the limit.

“It would be pretty hard to reach those numbers,” Zimmer says.

That’s not a license to add a lot of sweeteners to your drinks or drink soda with every meal. Sugary foods are bad for your heart, among other things, and should be consumed in moderation. But cancer risk from diet soda? It’s not something to lose sleep over.

“Artificial sweeteners definitely have a place [in diets], but we don’t want to consume them in excess,” Zimmer says. For example, sweeteners can add sweetness to foods without raising blood sugar. That’s helpful for people with diabetes or heart disease. Want to cut aspartame out greatly or all together? Try fruit-infused water, which you can make at home or get at the store. But check the label. Zimmer says drink mixes like Crystal Light often have aspartame. Hint Water is a better choice, she says. Also, look for high levels of added sugar on the food label.

And in general, talk to your health care provider or a dietitian if you have questions about what you should eat and drink.

What we eat is the biggest risk factor for heart disease

URBANA - Philip Ovadia, MD, has a roadmap for the next time you go to the grocery store: stick to the outer sections. That’s where you’ll find fruits, vegetables, dairy and less processed meats.

The further in you go, the more likely you are to encounter sugary, processed foods that can harm your health when consumed en masse.

“What we eat on a daily basis is the biggest risk factor for developing heart disease,” says Dr. Ovadia, an OSF HealthCare cardiothoracic surgeon who, himself, changed his eating habits and went on a weight loss journey.

Moreover, he says, health care experts have moved away from high fat and high cholesterol foods driving heart disease risk. That’s not a license to eat those foods all the time. But it’s more important, experts say, to keep an eye on sugary and processed foods.

Some chief examples: candy, snack cakes, cereal, cookies, chips, crackers and packaged or canned food. Think boxes, bags and colorful labels. After all, the manufacturers want you to buy the products.

And here’s one you’ll hear many doctors say: don’t drink your calories. In other words, avoid excess sugary drinks like soda and juice.

“The problem with fruit juices, as opposed to eating the fruit, is that a lot of the fiber has been stripped out of the juice,” Dr. Ovadia warns. “You’re getting very concentrated levels of sugar.”

For example, Dr. Ovadia says a glass of orange juice may contain the juice of around eight oranges. You wouldn’t think twice about downing the orange juice, but would you eat eight oranges in one sitting?

Consequences

In the short term, Dr. Ovadia says eating a lot of sugary and processed foods will cause your blood sugar level to rise.

“Increased sugar in the bloodstream is directly damaging to our blood vessels,” Dr. Ovadia says. “This is one of the things that can start the process of plaque formation, or blockages, in the blood vessels.”

Long term, Dr. Ovadia says your body can become insulin-resistant. Insulin is the primary hormone your body uses to control blood sugar level. If you’re insulin-resistant, insulin can’t do its job. Dr. Ovadia says this is a precursor to diabetes and metabolic syndrome, a cluster of unhealthy conditions. Both are “major” risks for heart disease, he says.

Some tips:

Look for “added sugar” on the food or drink label, and consider skipping that food.

Find foods that are as close to naturally occurring as possible. As Dr. Ovadia puts it: things that grow in the ground or things that eat things that grow in the ground.

“You should be able to look at your food and know exactly what’s in it,” Dr. Ovadia says. “It should have simple ingredients. You can look at them and know what they are.”

Or ask yourself: would my great grandparents have this food available? Would they even recognize it as food?

For breakfast, try fresh fruit or a hard-boiled egg instead of a biscuit. For lunch, eat a salad with ingredients you mixed instead of a pre-packaged salad. And for dinner, get a lean protein like chicken or fish from the deli counter, not sliced meat in a package.

Pay attention to how you feel after eating.

“If you find yourself getting hungry very quickly after eating, that’s a sign that food is not providing your body with the nutrition it’s looking for,” Dr. Ovadia says.

That means you shouldn’t look at junk food as “in moderation,” Dr. Ovadia says, because you’ll most always be left hungry. He prefers the phrase: “the lower junk food, the better.”

Key takeaways:

• Sugary, processed foods are a big risk for heart disease.
• When shopping, stick to the outer aisles. Buy items with simple ingredients.
• If you feel hungry again soon after eating, the food you ate is likely not providing the body the nutrition it needs.
