Alimenti

Alimenti are substances suitable for human consumption that provide energy and nutrients necessary for the body's functioning, growth, and health. The term encompasses a broad range of edible products of plant, animal, or microbial origin, consumed in meals or as snacks. In nutrition, attention is given to how different alimenti contribute calories, macronutrients, micronutrients, and hydration, as well as to their impact on health outcomes.

Alimenti can be categorized by origin (vegetal or animal), by processing level (natural, minimally processed, or highly transformed), and by their nutritional role (staple foods, protein sources, dairy, fats and oils, fruits and vegetables). Common groups include cereals and cereal products, legumes, fruits and vegetables, meat and fish, dairy, eggs, and fats and oils. Water and dietary fiber are essential components commonly associated with these foods.

Some alimenti are fortified with vitamins and minerals to address gaps in the diet; others are marketed as functional foods with health benefits beyond basic nutrition. Regulatory frameworks in many countries require safety assessments, accurate labeling, and disclosure of major allergens.

Dietary guidelines advocate variety, moderation, and balance among alimenti to meet energy and nutrient needs while supporting long-term health. Choices are shaped by culture, economy, and sustainability considerations, including environmental impact and food security.
