Solid foods are items that have a firm texture and do not contain significant amounts of liquid. They are typically consumed as part of a balanced diet and can include fruits, vegetables, grains, meats, and dairy products. Solid foods provide essential nutrients, such as vitamins, minerals, proteins, and carbohydrates, which are important for overall health and growth. When introducing solid foods to infants, it is recommended to start with pureed or mashed options to ensure safety and ease of digestion. Common first solid foods include rice cereal, pureed carrots, and mashed bananas. As children grow, they can gradually progress to more complex textures and flavors, promoting healthy eating habits.
