Nutrition for children from 1 to 3 years

Proteins and calcium: dairy products, meat, and eggs

Foods with high nutritional value remain the basis of a toddler's diet. A mandatory condition is the daily inclusion of a variety of fermented dairy products. These include kefir, natural yogurt, traditional sour milk (prostokvasha), and acidophilus milk. Pediatricians consider cottage cheese and cheese as key sources of easily digestible protein with maximum biological value.

The meat assortment remains the same as in the first year of life: dietary poultry and rabbit meat, lean pork, horse meat, and venison. An important rule applies to beef and veal: these types of meat can be introduced into the diet only in the complete absence of a history of allergic conditions in the patient.

Special attention is paid to fish, as it possesses exceptional nutritional value. The protein component of fish is absorbed by the child's body much easier than meat proteins, and natural fish oil is a vital source of fat-soluble vitamins. Additionally, chicken or quail eggs must be included in the daily menu.

Macronutrient balance: fats and carbohydrates

The fat component of the diet accounts for a massive share of the energy needs of a rapidly growing body, making up 40 to 50% of the total daily caloric intake. When planning the menu, it is important to maintain the proportion: the quota of plant fats must be at least 10–15% of the total volume of consumed lipids.

The carbohydrate component primarily performs an energy function, covering about 55% of total energy expenditure, and to a lesser extent, a plastic function. The main sources of carbohydrates are various grains, pasta, bakery products, as well as fresh vegetables and fruits. Sugar and certain confectionery products are permitted in the diet. Among the wide variety of grains, buckwheat and oatmeal are given absolute priority as they are the most nutritionally dense products in their category.

The role of vegetables and fruits: prebiotics and synergy

Vegetables and fruits play a crucial role in the children's diet as natural prebiotics. They gently stimulate the growth and development of normal intestinal microflora.

Their synergistic effect in nutrition is of particular interest. Although plant foods themselves are characterized by a very low content of their own protein and practically contain no essential amino acids, their presence on the plate is mandatory. Dietary fiber and specific acids in vegetables and fruits can significantly increase the bioavailability and absorption rate of proteins coming from other food products (for example, from meat or fish).

There are strict recommendations for the thermal processing of plant foods. To preserve maximum benefit, most fruits and berries (more than half of the daily norm) and a significant portion of vegetables (at least a third of the daily norm) must be given to the child in a fresh, i.e., raw state.

Culinary processing and strict dietary restrictions

In the age period from 1 to 1.5 years, a mandatory transition from completely homogenized (pureed) food to denser textures must occur. Food should contain noticeable "pieces." This is critically important for the timely and proper stimulation of the development of the masticatory apparatus.

Regarding restrictions, the use of any spicy condiments is categorically prohibited in the nutrition of young children. There are also strict rules regarding tonic beverages: traditional tea and coffee must be completely excluded from the diet of children under two years of age.

Organization of the feeding schedule: volumes and frequency

The feeding schedule for toddlers is subject to strict rules necessary for the adequate production of digestive juices by the gastrointestinal tract. Time intervals between any meals must be exactly 3.5–4 hours. Strict adherence to feeding hours is required.

The frequency of meals depends on the exact age. Up to 1.5 years of age, a child is offered 4–5 meals per day. For children over one and a half years old, the frequency of feedings is strictly fixed at 4 meals. The single portion volume for a 1–2-year-old child averages between 300 and 350 grams.

The daily caloric value is distributed unevenly:

• Breakfast: provides 25% of energy.
• Lunch: accounts for the maximum energy load — from 35 to 40%.
• Afternoon snack: accounts for about 10% of calories.
• Dinner: makes up 25% of the daily norm.
