For parents, a child who is a picky eater can turn every meal into a negotiation. A few bites here, a skipped meal there may not seem worrying at first. But when a child consistently eats too little or misses out on important nutrients, it can affect more than their weight.

New research involving Indian children suggests that targeted nutritional support, when combined with dietary counselling, may help children who are undernourished or at risk of undernutrition make stronger gains in height, weight, lean mass and other measures of healthy growth.

The study, conducted by Abbott and published in Children and the Journal of Clinical Medicine, followed 223 Indian children between approximately three and seven years of age who had picky eating habits and were undernourished or at risk of undernutrition.

What did the study find?

The children were followed for six months. All families received dietary counselling, while around half of the children also received additional oral nutritional support.

At the end of the study period, the children who received additional nutritional support showed greater improvements in several measures of growth compared with those who received dietary counselling alone.

One of the notable findings was height gain. The supplemented group had approximately 2.4 times greater height gain over six months. They also gained nearly 15 percent more lean mass.

The children showed improvements in weight and height without evidence of excess fat accumulation when assessed through BMI-for-age and body composition measurements.

The researchers also reported improvements in bone health indicators.

Bone mineral density increased by around 35 percent in the supplemented group, along with improvements in bone mineral content.

Growth is about more than the number on the weighing scale

When we talk about childhood nutrition, weight is often the easiest thing to notice. But healthy growth is more complicated than simply helping a child put on kilos.

Lean mass, for instance, includes muscle, bones, organs and other body tissues apart from body fat. An increase in lean mass can therefore provide a broader picture of physical development than weight alone.

The study found greater gains in lean mass among children who received additional nutritional support. This is important because adequate protein, energy and other nutrients are needed for children's bodies to build tissues as they grow.

The researchers also used dual-energy X-ray absorptiometry, or DXA, to assess body composition and bone health. 

What is catch-up growth?

Some children who have not been getting enough nutrition may experience slower growth than expected for their age. When nutritional needs are adequately addressed and growth begins to improve, this is often referred to as catch-up growth.

In the study, children at nutritional risk who received additional nutritional support showed up to four times greater gains in weight-for-age and height-for-age percentiles over six months compared with children who received dietary counselling alone.

A growth percentile does not mean that a child needs to reach a particular number. Instead, it helps healthcare professionals see how a child's growth compares with other children of the same age and sex and, importantly, whether that growth is following a healthy pattern over time.

Picky eating deserves attention when it affects nutrition

Picky eating is common during childhood. Many children go through phases where they reject certain foods, eat very small portions or suddenly decide that a previously loved food is unacceptable.

Occasional fussiness at mealtimes is not necessarily a sign of undernutrition. The concern is when limited food choices or inadequate intake persist and a child is not getting enough energy or essential nutrients to support normal growth.

The study also found that children receiving additional nutritional support had higher energy, carbohydrate and protein intake at three months, with improvements continuing at six months. They also showed greater improvements in mid-upper arm circumference percentiles, another measure used to assess nutritional status.

For parents, this is a useful reminder that the quality and adequacy of a child's overall diet matter just as much as how much they weigh.

What can parents do?

There is no single approach that works for every child. If a child is consistently eating very little, falling across growth percentiles, losing weight, or showing signs of nutritional deficiency, it is worth discussing the situation with a paediatrician or qualified dietitian rather than trying to correct it through supplements alone.

For children who are simply selective eaters, parents can start with everyday habits such as offering a variety of foods, including protein-rich foods, fruits and vegetables, whole grains and sources of healthy fats.

Repeatedly offering foods without pressuring children to finish everything can also make mealtimes less stressful.

Most importantly, parents should avoid judging a child's growth from weight alone. Height, weight, growth patterns, body composition, dietary intake and overall development all provide pieces of the picture.

Why early nutritional support matters

Childhood is a period of rapid physical development, making adequate nutrition particularly important. India's continuing burden of childhood undernutrition also means that identifying children who are not meeting their nutritional needs remains important.

According to the NFHS-6 data cited in the study, 29.3 percent of children under five in India are stunted and 31.8 percent are underweight nationally.

The new findings add to research suggesting that children at nutritional risk may benefit when dietary counselling is combined with appropriately targeted nutritional support. But the broader message for parents is simple: healthy growth is not just about making a child gain weight. It is about giving a growing body enough of the right nutrients to support height, muscle, bones and overall development.

Any child showing persistent growth concerns should be assessed individually by a paediatrician, who can determine whether dietary changes, monitoring or additional nutritional support may be appropriate.
