Eggs are highly nutritious due to their ideal balance of proteins, fats, vitamins, and minerals. Their structure—shell, white, and yolk—each provides specific benefits. The white is rich in coagulating and foaming proteins, while the yolk contains phospholipids, cholesterol, and carotenoids. Raw consumption is not recommended because of antinutrients like avidin. Beyond nutrition, eggs have significant industrial culinary uses in baking and food preparation.

Fish and shellfish are highly nutritious foods, rich in high biological value proteins, antioxidant vitamins (A, D, E), and essential minerals such as iodine. Their low fat and connective tissue content makes them easy to digest. Classification by type (fresh, frozen, salted, smoked, dried) and by fat content (lean, fatty, semi-fatty) is key to understanding their nutritional and culinary value. It's important to consider freshness, potential natural or environmental toxins, and the use of additives.

Rice, the staple food for half the world, is an excellent source of energy, high-quality protein and nutrients. Brown rice is notable for its fibre, vitamins and minerals, while parboiled rice offers enhanced nutritional value. Encouraging its consumption is key to healthier eating.

Eating whole grains isn’t just for weight loss—they are essential for a balanced diet. They provide fibre, vitamins, minerals and antioxidants, support healthy digestion, regulate blood sugar, and lower the risk of chronic diseases such as type 2 diabetes, obesity, and some cancers. Choose whole over refined whenever possible.
