Nutrition in early childhood is important part for toddler growth. In the age group of 2 to 6 years, toddlers go through rapid physical growth, significant cognitive development, and noticeable changes in their eating patterns. Protein for toddlers plays an indispensable role in numerous physiological functions. In these formative years, the body requires steady supply of nutrients especially proteins. As toddlers grow older, become active and independent, their nutritional requirements need to be met through well-planned, balanced and nutritious meals.1
Protein is an essential nutrient found in every cell of the body. It supplies amino acids, which act as the building blocks for muscles, skin, organs, blood components, and vital substances such as enzymes and hormones.2
During early childhood, dietary protein supports overall growth as well as key metabolic functions. At this stage, protein needs per kilogram of body weight are greater than in later years, owing to the rapid growth and development characteristic of the toddler period.3
The sources for protein vary in quality and including variety of sources can contribute to the overall toddler growth and development. Protein usually increases during the complementary feeding period as the requirements for proteins increase during this phase of growth.4
Protein for toddlers can be obtained from both plant as well as animal sources and including variety of them can help with improving the overall nutrient balance.5
Toddlers usually have unpredictable eating patterns. One day they might eat well and the next they may refuse the same food. Overtime, limited quantities and variety can reduce the protein intake.6
Here are few simple signs that parents can watch out for to check if toddler is getting enough protein.
Kids can become picky eaters and chose only particular foods like rice, roti or biscuits. If the protein containing foods like dal, eggs, paneer or curd are often refused, the overall nutrient balance is disturbed and protein intake is reduced.6
The toddler years are periods filled with movement and curiosity. If the child becomes less active than usual or gets tired easily while playing, it may be a sign to review the quality and quantity of protein intake. This is because proteins help with muscle building and maintenance that supports the daily activities of toddlers.7
Toddlerhood is the period of steady growth. If during this phase the physical development like height growth and weight gain appear to be slower than expected for that age, the dietary consumption especially protein for toddlers should be assessed.8
Snacking is a common habit seen among toddlers. When these snacks start to replace the major meals of the day, like breakfast, lunch or dinner the protein intake can drop. Packaged foods or junk do not provide the same nutritional profile that meals including all diverse food groups especially protein sources will do.9
Toddlers can become picky and choose to eat only a few protein sources repeatedly; there may be a lack of variety in amino acids from different foods. Including both plant and animal sources can help with improving overall dietary balance.6
Protein does not just support growth but also take part in other daily body processes enzyme and hormone synthesis, along with other essential nutrients. During childhood, nutrient gaps can lead to nutritional deficiencies. Regular meals that are well- balanced with all nutrients, can help toddlers meet their daily nutritional requirements. A balanced toddler nutrition includes:
In the toddler phase, the growth and development is gradual but continuous. The body weight of toddlers is lower compared to older children, but protein requirements per kilogram are relatively higher. That is why consistent protein intake is crucial. A combination of protein sources like milk and its products like curd, buttermilk, paneer, pulses, eggs, chicken, fish, and soy can help meet protein needs.10
One does not need to focus on eating large portions in one sitting, instead spacing the sources across every meal can be more practical. Maintaining a simple food dairy or record can help to identify whether protein for toddler is adequate. Sometimes it becomes difficult in a busy hold to maintain balanced toddler nutrition every single day.9
This is where options like Complan Nutrigro can help complement balanced meals. NutriGro is a nutritional drink for toddlers which has a 50:50 blend of whey and casein and 33 vital nutrients including iron, calcium, selenium, DHA and probiotic Bifidobacterium Lactis making it a different choice from regular health drinks. Including it along with balanced meals helps support physical growth, strong and healthy bones, cognitive and immune system development.
One must always review their toddler’s nutrition intake if –
Toddler years are a foundation phase for lifelong habits. Balanced nutrition does not need complex planning. A combination of plant and animal protein options, regular meal timings and multiple options across week can help to maintain appropriate nutrient intake. Protein for toddlers is an important part of growth.1 Hence including Complan Nutrigro along with balanced meals can make toddler nutrition more nutrient focused and practical. Simple choices made every day can contribute to growth and active play important during this phase.
