The causes of nutrition-related diseases are multifaceted and often involve a combination of genetic, environmental, and lifestyle factors. Poor dietary choices, lack of physical activity, and genetic predispositions can all contribute to these conditions. For instance, diets high in saturated fats, sugars, and processed foods are linked to obesity and cardiovascular diseases, while diets lacking in essential vitamins and minerals can lead to malnutrition and micronutrient deficiencies.
