Published in Cell Reports Medicine, the research from the Centre for Nutrition, Exercise, and Metabolism involved 53 healthy adults for up to 12 weeks. Participants followed either a moderate sugar diet (control), a low-sugar diet (less than 5% of calories from sugar), or a ketogenic (keto) low-carbohydrate diet (less than 8% of calories from carbohydrates).

Key findings include:

Increased Cholesterol: The keto diet raised cholesterol levels, particularly in small and medium sized LDL particles. The diet increased apolipoproteinB (apoB), which causes plaque buildup in arteries. In contrast, the low-sugar diet significantly reduced cholesterol in LDL particles.

Reduced Favourable Gut Bacteria: The keto diet altered gut microbiome composition, notably decreas...

First evidence that a beneficial gut bacterium can grow when fed a carbohydrate in cranberries. Many scientists are paying new attention to prebiotics, that is, molecules we eat but cannot digest, because some may promote the growth and health of beneficial microorganisms in our intestines, says nutritional microbiologist David Sela at the University of Massachusetts Amherst. In a new study, he and colleagues report the first evidence that certain beneficial gut bacteria are able to grow when fed a carbohydrate found in cranberries and further, that they exhibit a special nontypical metabolism.

Findings could add value to future food products or lead to a new supplement based on the cranberry, of which Massachusetts is a major producer.

What we eat not only nourishes us but also feeds the...
