Health status and conditions: Conditions like Coeliac disease, lactose intolerance, or allergies dictate certain food exclusions, while illnesses like heart disease might require reduced saturated fat levels.
Age: Dietary needs change throughout life. For instance, growing children need more protein, while the elderly might need higher nutrient-dense, low energy foods.

Micronutrients: Vitamins and minerals are needed in smaller quantities but are equally important. Deficiencies or excesses can have serious health implications.
Special dietary needs: Those with health conditions may have specific needs. For example, someone with high blood pressure should limit sodium intake, while a pregnant woman needs higher iron and calcium.
