For new parents, one of the biggest questions is often what a baby should eat and when different foods should be introduced. Sugar is particularly confusing. In many Indian households, babies are traditionally given milk or other foods with added sugar at an early age. But emerging research suggests that limiting added sugar during the earliest years of life could have important long-term health benefits.

A study published in the Proceedings of the National Academy of Sciences (PNAS) has drawn attention to the possible effects of sugar consumption during the first 1,000 days of life. The research suggests that lower sugar exposure during this critical period may be associated with a reduced risk of certain health problems later in life, including a possible reduction in cancer risk.

However, experts caution that the findings should not be interpreted as proof that avoiding sugar completely can prevent cancer. The broader message is that establishing healthier eating habits early in life may have lasting benefits.

What Did the Study Find?

Researchers examined a unique natural experiment in Britain involving the end of post-war sugar rationing.

Sugar rationing was lifted in September 1953, after which sugar consumption increased significantly. Scientists compared the long-term health outcomes of around 64,000 adults who were born around the period when rationing ended.

The comparison provided researchers with an opportunity to examine how differences in early-life sugar exposure could potentially affect health decades later.

The findings indicated that people exposed to lower levels of sugar during early childhood had differences in certain long-term health outcomes compared with those exposed to higher sugar consumption after rationing ended.

Researchers particularly highlighted the potential importance of nutrition during the first 1,000 days of life, a period considered crucial for growth and long-term health.

What Do Doctors Say About Sugar and Children?

Dr. Vipin Chandra Upadhyay of District Hospital, Ghaziabad, says that reducing excessive sugar consumption can help lower the risk of several metabolic problems later in life, including type 2 diabetes.

However, the connection between sugar intake and cancer is much more complicated. It would be incorrect to conclude that simply avoiding sugar during childhood guarantees protection against cancer in adulthood.

Excessive sugar consumption can contribute to excess calorie intake and weight gain. Over time, obesity and metabolic problems such as impaired insulin regulation can increase the risk of several chronic diseases.

Therefore, developing healthy eating habits from an early age can be an important part of maintaining good health throughout life.

Does This Mean Children Can Never Have Sweets?

Not necessarily.

The goal should not be to make children completely afraid of sweets or sugary foods forever. There is an important difference between occasionally having a small sweet treat and regularly consuming sugary drinks, packaged snacks, desserts and other foods with large amounts of added sugar.

Parents should focus primarily on the overall quality of a child's diet and avoid making high-sugar foods a daily habit.

What Should Parents Include in a Child's Diet?

Instead of relying on foods containing added sugar, parents can focus on nutritious options appropriate for the child's age and developmental stage.

A balanced diet can include foods such as:

• Fruits and vegetables

• Milk and other suitable dairy foods

• Pulses and legumes

• Whole grains

• Adequate sources of protein

• Other nutrient-rich foods recommended for the child's age

Parents should also encourage children to remain physically active as they grow.

Early Eating Habits Can Shape Future Choices

Pediatric surgeon Dr. Brahmanand Lal explains that sugar itself does not need to be treated as completely forbidden, but moderation is important.

Children who become accustomed to very sweet foods and drinks from an early age may continue seeking those flavours as they grow older. On the other hand, introducing a variety of nutritious foods and limiting added sugar can help establish healthier eating patterns.

The key takeaway for parents is therefore not simply “never give your child sugar.” Instead, it is about limiting unnecessary added sugar, avoiding excessive consumption and building healthy eating habits from the beginning.

A child's early diet can influence their relationship with food for years to come. Choosing nutritious foods and keeping added sugar to a minimum may be one of the simplest steps parents can take toward better long-term health.
