Final answer:
Registered Dietitians are healthcare professionals specializing in nutrition who assist in managing and preventing obesity-related diseases by designing personalized nutrition plans and educating on healthier food choices.
Step-by-step explanation:
Registered Dietitians (RDs) are vital professionals in managing and preventing obesity, which has become a worldwide health concern. RDs complete a rigorous educational pathway that includes courses in nutrition, chemistry, biochemistry, biology, microbiology, and human physiology. They are required to undergo a supervised internship program and pass a national examination to become experts in the chemistry and physiology of food, particularly in proteins, carbohydrates, and fats.
These nutritional professionals use their expertise to design personalized nutrition plans in healthcare facilities, nursing homes, schools, and private practices. For instance, they guide patients with diabetes on how to manage their blood sugar levels by making informed decisions about their carbohydrate intake. By understanding nutrient and energy density, RDs help clients make healthier food choices to treat and prevent diseases related to obesity, such as diabetes and heart disease, enhancing patient health and wellbeing.
