Ask a Dietitian – What’s the latest news about aspartame?

 

Aspartame is a low-calorie, artificial sweetener that is about 200 times sweeter than white sugar. It’s found in some diet soft drinks, desserts, yogurt, chewing gum and even some chewable vitamins. In Canada, aspartame has been approved for use as a food additive since 1981.

You may have seen recent news headlines about aspartame and cancer. Here’s what you need to know.

Two different groups did two different types of reviews

The health impacts of aspartame were assessed by two different organizations and they looked at two different things.

Review #1 by IARC – International Agency for Research on Cancer

The IARC conducted a HAZARD analysis. This type of review assesses the level of certainty that a substance can cause cancer. It does not consider dose or amount. Aspartame was classified as a Group 2B carcinogen, meaning that it is possibly carcinogenic with “limited evidence in humans and less than sufficient evidence in experimental animals.”

For background, substances classed in Group 1 are considered carcinogenic with “sufficient evidence in humans”, and those in Group 2A are considered probably carcinogenic with “limited evidence in humans and sufficient evidence in experimental animals.

Review #2 by JECFA – Joint Expert Committee on Food Additives (a joint working group of the World Health Organization and the Food & Agriculture Organization)

A second review of aspartame was undertaken by JECFA where they conducted a RISK analysis. This type of review assesses the exposure level or amount consumed that can pose a risk to health. They concluded that aspartame does not pose a safety risk in the amounts that people typically consume.

JECFA also confirmed that the Acceptable Daily Intake (ADI) of 40 mg aspartame per kg body weight is still appropriate. This is the same limit set by Health Canada. In USA, the limit is 50 mg aspartame per kg body weight per day.

What does 40 mg aspartame per kg body weight per day look like?

For a 70 kg adult, the Acceptable Daily Intake of aspartame would be 40 x 70 = 2,800 mg.

One standard can of diet soft drink contains between 200-300 mg of aspartame. In other words, you would need to consume 9-14 cans of diet soft drink in a day to reach the maximum limit of 2,800 mg of aspartame, assuming that you don’t get aspartame from other sources. This is the maximum amount of aspartame that can be consumed daily over a lifetime without presenting an appreciable risk to health.

Read labels carefully for aspartame

Currently, aspartame is listed on the food label along with the aspartame content per serving. However, Health Canada has just announced new food labelling regulations for aspartame and other sweeteners.

By January 1, 2026:

  • Aspartame will no longer need to be listed on the front of packages.
  • Aspartame will still appear in the ingredients list, but the amount of aspartame (in mg) per serving will no longer be shown.
  • Foods sweetened with aspartame must still include a statement at the end of the ingredients list that warns individuals with phenylketonuria (PKU) that the food contains phenylalanine (this is a type of amino acid found in aspartame and needs to be avoided by people who have PKU).

See images below for a comparison of the original / current labelling of aspartame compared to the new labelling rules.

The Bottom Line

  • Remember that the amount or dose of any substance is important when thinking about the risk to your health. According to the WHO and FAO, aspartame is safe in amounts that people typically consume.
  • Look at all the products you consume which may contain aspartame such as diet drinks, sugar-free gum, dairy products and chewable vitamins. Stay within the Acceptable Daily Intake of 40 mg per kg body weight per day.
  • Enjoy eating a variety of wholesome foods to lower your cancer risk: whole grains, nuts, seeds, vegetables, fruit and healthy fats.
  • Take other healthy actions to lower your cancer risk: live smoke-free; be sun safe; move more and sit less; eat well; limit alcohol; and get screened for different types of cancer as recommended by your health care practitioner.

New Front-of-Package Nutrition Labels are Coming to Canada

A magnifying glass with the words "High in sat fat, sugars, sodium"

 

 

 

 

 

This article originally appeared on Canadian Food Focus, and I received monetary compensation from them to research and write this information. My articles represent my personal and professional views. I am one of many dietitian writers for Canadian Food Focus, which is a source for Canadian food and farming stories that provide advice to help you make confident food choices.

 

You’re probably already familiar with the Nutrition Facts information found on the back of food packages. Health Canada is now introducing a new nutrition symbol that will appear on the front of food packages. This new front-of-package (FOP) nutrition symbol will help consumers quickly identify foods which are high in saturated fats, sugars and / or sodium. Here’s what you need to know.

Watch my national TV interview about Front of Package labelling.

Background

According to Heart and Stroke, 60% of the food we buy is prepackaged and processed, and many of these foods may be high in saturated fats, sugars and / or sodium. Eating a diet that’s high in these nutrients of concern is linked to a higher risk of heart disease, stroke, high blood pressure, obesity, diabetes and some types of cancer. At the same time, 8 out of 10 Canadians say that nutrition is important when choosing foods.

To help Canadians make informed choices, Health Canada is introducing a new front-of-package (FOP) nutrition symbol to identify packaged foods which are high in saturated fats, sugars and / or sodium. The regulations came into effect on July 20, 2022 and food companies have until January 1, 2026 to update their packaging their labels. Over 40 countries including Chile, Argentina, Mexico and New Zealand, currently have a front-of-package nutrition labelling system.

 

What does the new front-of-package (FOP) symbol look like?

The new FOP symbol is a black and white image of a magnifying glass along with the name(s) of the nutrient(s) of concern – saturated fat, sugars and / or sodium – that are deemed high in the packaged food or beverage. It may appear either as a horizontal or vertical symbol. The FOP symbol may appear on the food package as one bilingual symbol or as two separate symbols in both official languages.

The FOP symbol will always appear on the upper right half of the food package. In the sample chocolate bar below, the symbol indicates that the food is high in saturated fat and sugars.Sample chocolate bar with the front-of-package symbol for high saturated fat and sugars

 

 

 

 

 

Which foods will need to show the FOP symbol?

For most packaged products, the definition of “high” means that the food or beverage contains 15% or more of the Daily Value for saturated fat or sugars and / or sodium per serving.

For example, take a look at the nutrition facts information below for a can of soup. The saturated fat is at 5% DV, the sugars is at 2% DV but the sodium is at 36% DV. So this soup would need to show the front-of-package nutrition symbol with the word sodium to let consumers know that this product is high in sodium.

Nutrition facts table for a can of soup

For foods with a small serving size such as salad dressings or pickles, the criteria is 10% DV instead of 15% DV for saturated fat, sugars and sodium. And for pre-packaged main dishes that have a larger serving size, such as a frozen pizza or frozen lasagna, the criteria is 30% DV for those nutrients.

Which foods are exempted from the FOP symbol?

This is a list of some foods which are exempted either because of a recognized health benefit, technical or practical reasons. 

  • Plain fruits and vegetables
  • Plain, unsweetened 2% milk & whole milk
  • Plain cheese and yogurt*
  • Plain nuts / seeds & nut / seed butter
  • Eggs
  • Raw, plain single ingredient meat, poultry & fish, including ground meat
  • Butter, margarine, ghee; Vegetable oils; Sugar, honey, molasses, maple syrup; Salt (e.g. table salt, sea salt, Kosher salt, garlic salt, onion salt, celery salt, etc.) – It would simply be redundant and impractical to put a FOP symbol on these foods.

Any of the foods noted above are no longer exempt if they’re made with an ingredient that contains saturated fat, sugars and / or sodium. For example, a bag of plain salad is exempt from the FOP regulations. But is the bag of salad contains bacon bits and salad dressing, the FOP symbol may apply. Similarly, if salt is added to plain nuts, the FOP symbol may apply.

*Cheese and yogurt made from dairy these foods naturally contain saturated fat, sugars (lactose) and sodium (needed in the cheese-making process). However, these foods contain calcium which is considered a “shortfall nutrient” since many Canadians may not be getting enough and calcium. Any plain cheese or yogurt is only exempt from the FOP symbol if a serving of the food contains at least 15% DV for calcium (or at least 10% DV for calcium in foods with a serving size of 30 grams / 30 mL or less). The ongoing need for this exemption will be reassessed after 10 years.

Other exemptions include:

  • Foods that are only sold at a farmer’s market, flea market, craft show, road-side stand or sugar bush by the person who prepared and processed the product
  • Packaged individual portions of foods that are only intended to be served by a restaurant to accompany a meal or snack, such as coffee creamers or individually packaged crackers often served with soups at restaurants
  • Foods sold in very small packages or with limited display space, such as milk, cream and goat’s milk which are sold in refillable glass containers since there available labelling space is limited to the lid

Pros and Cons

Pros: The FOP symbol will help consumers make informed food choices. In Chile, where a similar FOP labelling system has been in effect since 2016, 92% of consumers said that the FOP label influenced their food purchase. And overall household food purchases in Chile contained 37% less sodium and 27% less sugars.

Another pro is that this new nutrition labelling policy will inspire food companies to reformulate their products. In the next four years, expect to see new and improved products containing less saturated fat, sugars and sodium.

Cons: The FOP symbol could promote a “good food vs bad food” mentality which supports diet culture. Remember that we eat food for more than just nutrition. We eat food for celebration, comfort and connection.

Sue’s advice

Use the new FOP symbol as another tool to help you make informed choices. Read the Nutrition Facts table on the back of the package to see what other nutrients are offered in the food. Look at the ingredients list to determine whether any fat, sugars or sodium have been added to the product. If you happen to occasionally eat a food / beverage that has a FOP symbol, don’t feel guilty or ashamed. All foods can be enjoyed in moderation and fit into a healthy, balanced diet.

 

 

Does diet affect erectile function?

It’s the question you may have always wondered, but were too shy to ask!

June is Men’s Health Month, so let’s take a look at some of the research on this topic.

A study published in the Journal of the American Association Network Open journal suggests that a healthy dietary pattern may play a role in maintaining erectile function in men. Researchers from the University of California and Harvard University looked at the food and nutrient data from over 21,000 healthy men aged 40 to 75 who had no previous diagnosis of erectile dysfunction or diabetes or heart disease. The men were part of the Health Professionals Follow-up Study. The researchers found that men at all ages who followed a Mediterranean-style diet had the lowest risk of erectile dysfunction. A Mediterranean-style diet focuses on fruits, vegetables, nuts, legumes and fish.

Fruits and vegetables contain special plant nutrients called flavonoids.  Researchers in Greece found that eating fruits and vegetables lowered the risk for erectile dysfunction by 32% in men aged 18 to 40 years.

Another study from researchers in Spain looked at 83 healthy men aged 18-35. For 14 weeks, these men were asked to follow their usual diet and were divided into 2 groups – one group also ate 60 grams (about ½ cup) of nuts a day such as walnuts, almonds and hazelnuts; the other group of men did not eat nuts. The study found that a healthy diet supplemented with mixed nuts may help to improve erectile and sexual desire.

Bottom line: Fruits, vegetables and nuts are the foundation of an overall healthy diet that can benefit not only your heart health but also your sexual health.
