Diet changes refer to any modifications made in one's eating habits or food choices. This can include altering what types of food are consumed, such as increasing intake of fruits and vegetables, reducing processed foods, or eliminating certain food groups altogether (such as gluten-free diets). Diet changes may also involve adjustments in portion sizes, meal frequency, or eating habits. The goal of these modifications can vary from improving overall health to managing specific medical conditions like high blood pressure or diabetes.
