Fattening Foods Differ From Person to Person
Food that may be fattening for one person may not be for another, according to research at the Weizmann Institute of Science in Israel.
And that, say the scientists, lends more support to the belief that people need to have diets that are more personalized.
Maintaining normal blood glucose levels is key to avoiding conditions such as obesity, metabolic syndrome, and hyperglycemia - a risk factor for type 2 diabetes. Experts say that because blood glucose is regulated by diet, people need to choose foods that when metabolized, lead to normal glycemic responses.
During its study. the research team tracked the effects of 46,898 meals consumed by 100 people. Data was collected via questionnaires, body measurements, blood and glucose tests, stool samples and a mobile app. As expected, age and body mass index (BMI) affected blood glucose levels.
But what the researchers didn’t expect was the wide variety of responses people had to the exact same meal. One woman who had an obesity diagnosis and was pre-diabetic, showed blood sugar spikes after eating tomatoes -- considered a healthy food.
After conducting a microbiome study, the team found that certain microbes changed the way a person’s blood sugar rose after each meal.
They used this information to fine-tune a personalized dietary plan for 26 participants, which ended up reducing their blood sugar levels and even altered their gut microbes.
