Dietary modifications refer to changes made to a person's eating habits to improve health or manage specific conditions. These changes can include altering portion sizes, selecting healthier food options, or eliminating certain ingredients. For example, someone with diabetes may need to monitor their carbohydrate intake, while individuals with food allergies might avoid specific allergens. These modifications can be guided by healthcare professionals, such as dietitians or nutritionists, who provide personalized advice based on individual needs. Implementing dietary modifications can lead to better overall health, weight management, and improved well-being, making it an essential aspect of preventive care.
