A specialist explains how daily yogurt affects the body
Yogurt has attracted attention in nutritional guidance because it contains several components associated with different areas of health. Products with live cultures may support the balance of intestinal bacteria and aid digestion. The food also provides protein, calcium, phosphorus and vitamins, nutrients relevant to maintaining muscle mass and bone health over the course of life.
Anderson de Souza, a nutrition professor at UNINASSAU Boa Viagem, said scientific interest in yogurt extends beyond the digestive system. He referred to research linking yogurt consumption with a lower risk of type 2 diabetes and metabolic syndrome, as well as studies associating the habit with better cardiovascular outcomes.
Souza also noted a limitation in that body of research: much of it is observational. Such studies identify an association between eating yogurt and particular health results, but they do not establish that yogurt directly caused those results.
The label “probiotic” does not apply automatically to every yogurt containing microorganisms. Classification depends on the strains present, the amount of viable bacteria in the product and scientific evidence demonstrating health benefits. Consumers are therefore advised to examine product labels before buying.
Individual health conditions can affect whether, and which type of, yogurt is suitable. People allergic to milk protein should avoid conventional products containing that ingredient. Those with lactose intolerance may use lactose-free varieties, with guidance appropriate to their circumstances.
People with chronic kidney disease require additional care because yogurt contains protein, phosphorus and potassium. Their intake should be considered alongside individual nutritional needs and assessed by a health professional. The article describes yogurt as compatible with a balanced diet when product selection and consumption patterns take account of both the characteristics of each version and the consumer’s health status.
