The uptick in online activity comes less than a week after Toronto Public Health reported there have been 13 cases of IMD in the city this year, two of which were fatal. According to a press release, the number to date is the highest total number of cases since 2002.

Earlier this year, Manitoba Health and health officials from Kingston, Ont. Both reported increases in cases of IMD.

A new study on the artificial sweetener xylitol, a natural sugar alcohol found in fruits and vegetables, has prompted a 950 per cent increase in web searches. The study, published in the European Heart Journal, found that people who consume the highest levels of xylitol have an increased risk of experiencing heart attack and stroke.

Lead researcher Dr. Stanley Hazel, a physician scientist for the Cleveland Clinic, said via press release, “This is the second sugar alcohol that we’ve identified that at physiologic ranges, the levels that we’re seeing in the blood, is linked to heightened clotting risk, heightened risk for heart attack, stroke and frankly, death.”

In 2023, Hazel published a study on erythritol, a sweetener added to low-calorie and zero-calorie foods and drinks, which also increased risk of cardiac events such as heart attack and stroke.

While Hazel said xylitol isn’t as common as other artificial sweeteners, it is used in some sugar-free, low-calorie and keto-friendly foods, as well as oral products like toothpaste and gum.

“One of the things I would like to see happen out of this research is a reappraisal of the regulatory guidelines around artificial sweeteners, or at least a call for more research on this topic so that we can drill down and make sure we’re not inadvertently having people reach for something they think is a healthy choice, and it not be a healthy choice,” Hazel said.

Researchers suggest opting for eating whole foods or choosing (in moderation) foods sweetened with sugar or honey as a healthy alternative.

Could changing your diet to one that has a low-carbon footprint improve your health and be good for the planet? A study led by Harvard T.H. Chan School of Public Health found that people who followed what’s called the Planetary Health Diet had a 30 per cent lower chance of premature death compared to those who didn’t. According to the study, the diet is associated with lower risks for cancer, heart disease and lung disease.

The findings prompted a 5,000 per cent increase in web searches for the diet — but what is it?

The food plan was created in 2019 by the EAT-Lancet Commision, which created a sustainable food model for 10 billion people by 2050.

The Planetary Health Diet consists of mainly fruits, nuts, vegetables and whole grains. moderate meat and dairy intake and as few processed foods as possible. The diet contains foods that are produced with less greenhouse gas emissions, reduced cropland, fertilizer and water use.
