The Canadian Cancer Society is recommending that people stay within existing daily limits of aspartame consumption and is encouraging more studies on the artificial sweetener after the World Health Organization deemed it 香蕉视频直播減ossibly carcinogenic.香蕉视频直播�

The classification 香蕉视频直播渕eans that there香蕉视频直播檚 limited evidence suggesting that it may cause cancer in humans and that additional research is needed,香蕉视频直播� said Elizabeth Holmes, director of health policy at the Canadian Cancer Society, in an interview on Friday.

Holmes said the society welcomes research proposals on aspartame and will consider funding them.

Two WHO-affiliated agencies conducted two independent reviews to assess health risks associated with consumption of aspartame, which is commonly found in diet beverages, gum and sugar-free sweet treats such as syrup or gelatin dessert.

In reviewing available studies in both humans and animals, the International Agency for Research on Cancer (IARC) and the Food and Agriculture Organization Joint Expert Committee on Food Additives (JECFA) found limited evidence that aspartame could be associated with a type of liver cancer.But the findings could not rule out the possibility that other variables might account for the link.

Better studies, including randomized controlled trials, are needed to determine more definitively whether or not aspartame causes cancer, the study summary said.

There was 香蕉视频直播渘o convincing evidence香蕉视频直播� to suggest current recommendations on safely eating or drinking aspartame should be changed, it said.

Health Canada and the WHO both recommend a daily limit of 40 mg of aspartame per kilogram of body weight.

A WHO news release breaks it down: since a can of diet soda contains about 200 香蕉视频直播� 300 mg of aspartame, an adult who weighs 70 kg would need to consume more than nine to 14 cans per day to exceed that limit.

David Ma, a professor of nutritional sciences at the University of Guelph, said the daily aspartame consumption of most Canadians likely falls within that limit.

香蕉视频直播淯nfortunately, there are probably a few individuals drinking (above) that level. So those would be the ones that should be most concerned about their intake,香蕉视频直播� Ma said.

In an emailed statement, Health Canada said it will review the research and 香蕉视频直播渄etermine whether action is needed for aspartame in Canada based on the scientific data in the full reports.香蕉视频直播�

The WHO has four classification levels for items assessed for their potential to cause cancer: carcinogenic to humans, probably carcinogenic to humans, possibly carcinogenic to humans, and not classifiable as to its carcinogenicity to humans.

Those levels are based on how strong the evidence is that something, including food, drink, chemicals and environmental hazards, is linked with cancer. The classification levels aren香蕉视频直播檛 a statement about the 香蕉视频直播渄egree of risk香蕉视频直播� of developing cancer. The risk often varies with the amount consumed or levels of exposure. The type of cancer the food or drink is linked to also varies.

Tobacco, alcohol and processed meat are among more than 120 items currently classified as carcinogenic on the WHO香蕉视频直播檚 website. There are more than 90 items listed as 香蕉视频直播減robable香蕉视频直播� carcinogens, including red meat.

When it comes to 香蕉视频直播減ossible香蕉视频直播� carcinogens such as aspartame, more than 320 items are listed. They include many chemicals, such as chloroform and lead.

It香蕉视频直播檚 important to think of substances listed as carcinogenic, probably carcinogenic or possibly carcinogenic as 香蕉视频直播渉azards香蕉视频直播� rather than 香蕉视频直播渞isks,香蕉视频直播� Ma said.

For example, driving a car is inherently a hazard, he said. But the risk of injury is lowered by actions that we take.

香蕉视频直播淲e accept that because overall, on a daily basis, millions and millions of people drive and the risk is relatively low because we put on our seat belt, we follow the rules of the road, we do not drive dangerously at high speeds,香蕉视频直播� Ma said.

Similarly, aspartame is a 香蕉视频直播渉azard香蕉视频直播� but 香蕉视频直播渢he level of risk is low香蕉视频直播� if we don香蕉视频直播檛 consume too much, he said.
