In recent years, both parents and doctors have noticed a concerning increase in children with behaviour problems – from chronic irritability and poor concentration to hyperactivity and mood swings.

The increasing reliance on ultra-processed foods, and too much sugar in daily diet, has quietly entered lunchboxes, snacks and celebrations, often replacing meals that would provide balanced nutrition. While foods may be convenient and the ‘easier’ option to rely on, they can play a considerable role in shaping a child’s growing brain.

Dr Poonam Sidana, Director of Neonatology and Paediatrics at CK Birla Hospital, Delhi, tells Moneycontrol that high sugar intake results in dramatic energy levels spikes as well as crashes while ultra-processed foods lack vital nutrients that are responsible for regulating emotions of the healthy function of the mind. Such dietary patterns, if continued through school-life, can affect mood, attention and behaviour.

Health risks of ultra-processed foods

Understanding these relationships is the first step to cultivating healthier choices for children's physical and emotional health.

1. UPFs trigger sudden blood sugar spikes and drops

Foods such as biscuits, chips, instant noodles, and snacks, along with sugary fluids, trigger extreme highs and lows of energy levels, and this cycle tends to make kids irritable and moody.

2. Artificial additives alter emotional/brain chemistry

"Synthetic colours, flavours, preservatives, and emulsifiers commonly found in UPFs can interfere with neurotransmitters," says Dr Sidana. Neurotransmitters are chemicals found in the brain that are necessary for such things as attention, learning, and impulse control.

3. High sugar can impact gut-brain axis

Too much sugar promotes the growth of bad bacteria in the intestines; this may result in inflammation as well as impair the intricate process between the intestines and the brain, often causing high levels of anxiety, aggression, and hyperactivity.

4. UPFs weaken memory and concentration

Studies show that children who are accustomed to eating processed snacks are more likely to underperform in those areas that require intense focus and memory recall.

5. Poor diet models ADHD-like behaviour:

Symptoms including restlessness, impulsiveness, irritability, poor sleep, and difficulty concentrating are now increasingly being found to be caused by a diet rich in sugar and processed foods, and not any neurological disorders.

6. UPFs trigger emotional eating

When kids experience stress or boredom, these can lead to intense cravings for sugary or salty foods. This can create a vicious circle of dependence that can affect emotional regulation because of the changes that occur in the reward pathways of the brain.

What parents can do

Packaged snack foods: Replace them with: Whole foods such as fruits, nuts, homemade chillas, idlis, and sandwiches.

Revise reward systems: Do not use flavored drinks, sugary cereals, and chocolates as immediate rewards for desired behaviour.

Educate early: Teach children how to read labels so they understand what they are consuming.

Build on stabilisation: Serve them fiber and healthy fats to help provide stable levels of enduring energy.

Connect: Eat meals together as a family rather than eating in front of the computer or TV.

Simple dietary changes can have dramatically positive effects upon the child’s behaviour as well as the clarity of his or her mind within just a few weeks.
