We do love sweet foods. Alas, sugars have calories but nothing else of nutritional value and they are associated with poor health.

What are the poor makers of sugary foods and beverages to do? Here are some recent approaches:

Sugar cubes

And then there are the safety questions.

But questions about sugar substitutes have been swirling for decades, with scientists and public health officials suggesting they might come with certain health risks of their own. The research on how sugar substitutes affect our bodies is preliminary, complex and sometimes contradictory.

 

…But longer-term studies on sugar substitutes have found no weight loss benefits, and even some harms. For this reason, the World Health Organization recommended in 2023 that people avoid using sugar substitutes for weight control or better health, citing research that linked them to greater risks of health concerns like Type 2 diabetescardiovascular diseaseobesity and earlier death. The sugar alcohols erythritol and xylitol have also been associated with a greater risk of heart attack and stroke.

What to do? For me this is easy.

  • I don’t like the way they taste.
  • They are a marker of ultra-processed foods.
  • I don’t eat anything artificial if I can avoid it.

How harmful are they? I don’t know for sure but would prefer not to be a guinea pig.
