Does yoghurt help in prevention of diabetes and obesity?

Yoghurt, a low-calorie fermented dairy product, offers a balanced mix of proteins, essential nutrients, and beneficial bacteria. Studies have linked yoghurt consumption to lower risks of obesity, diabetes, osteoporosis, and heart disease while improving gut health and boosting immune function. According to an economic model for yoghurt use in diabetes risk reduction, the consumption of 100 grams of yogurt each day by adults can lead to 388,000 fewer people developing diabetes in the next 25 years.

In the study, researchers analyzed yogurt consumption data in the Argentine population, revealing an average annual intake of four kilograms per person. Over the past decade, both full-fat and skim yogurt consumption has declined by 44%. In 2019, diabetes prevalence was estimated at 13%.

Low-fat yogurt's anti-diabetic properties stem from its low glycemic load and nutrient content, including proteins, calcium, magnesium, and vitamin D. Certain saturated fatty acids in yogurt are linked to reduced diabetes risk, with daily consumption of 50 grams associated with a 7% lower risk.Yogurt's beneficial bacteria improve blood lipid profiles, lower cholesterol, and boost antioxidant status in diabetic patients. Additionally, yogurt's organic acids, like lactic acid, reduce postprandial blood glucose and insulin levels.

Gut microbiota imbalance is a key factor in obesity, causing changes like increased fat deposition and metabolic dysfunction. Yoghurt, with its nutritious elements and beneficial bacteria, can mitigate obesity risk by replacing unhealthy foods. It also influences appetite regulation, energy balance, and body mass index (BMI).

The findings of the study indicated that yogurt consumption could be beneficial for the prevention and management of both diabetes and obesity. The rising prevalence of these chronic diseases throughout the world emphasizes the importance of encouraging people to incorporate yogurt as part of their healthy diet to improve public health.
