Why healthier children begin with healthier families, food environments and communities
When we talk about improving children’s nutrition, we often focus on changing the child. We scrutinise the lunchbox, negotiate over veggies and wonder how something can be “disgusting” on Tuesday when it was perfectly acceptable last Thursday.
But children do not make food choices in isolation. They eat what is available, affordable, familiar and accepted in the homes and communities around them. Sending a child home with a nutrition leaflet and expecting the household food environment to change is a little like teaching someone to swim without ever putting them in water. The information may be correct, but the environment still determines what happens next.
August is Child Health Month, an opportunity to think not only about how we care for children when they become unwell, but also about the conditions that shape their health long before disease develops.
At The Noakes Foundation, our Eat Better South Africa (EBSA) programme primarily works with adults living with, or at risk of, diet-related chronic diseases such as type 2 diabetes, obesity and hypertension. We have not measured health outcomes in their children, so we can’t claim that changing an adult’s diet automatically improves a child’s health.
What our work has shown us, however, is that food choices are rarely individual. They are woven into family routines, household budgets, cultural traditions, social expectations, and the realities of the local food environment. When we help the adults who buy the food, prepare the meals, and decide what is considered “normal” at home, it is reasonable to think that the effects may extend beyond the individual participant.
Children inherit habits before they inherit knowledge
Children learn about food long before they understand nutrients, blood glucose, or metabolic health. They learn by watching what appears on the table, what is packed for school, what is used as a reward, what adults reach for when they are tired, and which foods are treated as everyday staples. Most children do not wake up one morning and independently decide that sugary cereal, fruit juice and ultra-processed snacks should form the basis of their diet. Those foods are simply part of the environment they have inherited.
This is why nutrition education aimed only at children can have limited reach. A child may learn at school that sugary drinks should not be an everyday choice, but that knowledge is difficult to apply if those drinks remain routinely available at home, and vice versa. Conversely, when a household begins drinking more water, preparing more whole foods and reducing highly processed products, healthier behaviour becomes part of ordinary family life rather than another rule imposed on the child.
Don’t forget that children are remarkably observant, particularly when we would prefer that they were not. They notice what adults do, not only what adults tell them to do.
Parents do not make choices in a vacuum
It is easy to speak about “healthy choices” as though every family is standing in the same supermarket aisle with the same budget, the same amount of time and the same options available. The reality is anything but. In South Africa, food decisions are shaped by income, transport, time, electricity, cooking facilities, local shops, family expectations and the need to stretch limited resources across an entire household. Food insecurity and the dual burden of malnutrition mean that undernutrition and excess weight can exist in the same community, and sometimes in the same family.
For a parent under pressure, the cheapest calories, the quickest meal or the food most likely to fill a hungry tummy may be the only option. A vegetable does not suddenly become affordable because an infographic says it is healthy, and a complicated recipe is not especially helpful to someone with limited time, equipment or electricity.
Recognising these constraints does not mean lowering our standards for good nutrition. It means starting with reality. If nutrition guidance cannot survive contact with a family’s budget, kitchen and daily routine, it is unlikely to survive for very long.
Culture is an asset, not a barrier
Improving nutrition should not require families to abandon familiar foods or adopt a diet that feels imported, expensive or entirely disconnected from daily life. Healthy eating should not require a second salary, a degree in biochemistry or ingredients that can only be found in a shop 40 kilometres away.
Traditional food knowledge, shared meals and local cooking practices can provide a powerful foundation for change. Culture is not the enemy, and traditional foods are not automatically the problem.
The practical task is to work alongside families to adapt familiar meals in ways that better support metabolic health. This may include reducing added sugar and refined carbohydrates, limiting ultra-processed foods and refined oils, and building meals around affordable whole-food options that are locally available and culturally acceptable. People are far more likely to sustain change when advice acknowledges who they are, what they eat and how they live. A theoretically perfect diet that no one wants (or can afford) to follow is never going to be a useful intervention.
Knowledge is necessary
Helping people understand food is an important starting point. Seeing how much sugar is contained in a fizzy drink can be eye-opening. Understanding how bread, cereal, juice, pasta and potatoes contribute to the carbohydrate content of a meal can help make an otherwise invisible problem visible.
But knowledge alone does not answer the questions that arrive as soon as someone gets home:
What can I buy instead? How do I feed the family on the same budget? What happens when cravings start? What do I serve at a social gathering? How do I make changes when the rest of the household is not interested? This is where nutrition advice often falls apart, not because people do not care, but because real life has entered the chat.
Through EBSA, we combine practical nutrition education with individual coaching, group sessions, demonstrations, follow-up measurements, and ongoing WhatsApp support. Participants can ask questions, share meals, discuss challenges, and encourage one another.
Our most meaningful successes have not come from simply handing someone a food list and wishing them luck. They have grown through confidence, practical problem-solving, accountability, shared experience, and the reassurance that someone is available when things do not go according to plan, which, in most households, is fairly regular.
Communities change families. Families shape children.
Behaviour change is social. One person may begin the process, but meals are shared, groceries are negotiated, and habits are reinforced, or undermined, by the people around them.
This is why community coaches are so valuable to EBSA. They understand local constraints, communicate in familiar and relatable ways, and can translate broad nutrition principles into something that works in a real home, with a real budget and real people who may have strong opinions about what should be served for supper.
When healthier choices are supported not only by one determined parent, but also by other family members, peers, community coaches, clinics, schools and local organisations, they have a better chance of becoming normal.
That is the “village” in child health. It is not an abstract ideal or a collection of people standing around offering unsolicited parenting advice. It is a network of adults and institutions whose everyday decisions create the conditions in which children grow.
Creating the conditions for healthier childhoods
Child Health Month should remind us that responsibility for children’s health cannot sit with children alone, but it cannot sit with parents alone either. Families need practical knowledge, but they also need affordable food, accessible support, realistic guidance and local environments that make healthier choices possible. Schools, clinics, community organisations, policymakers, researchers and the food industry all form part of the village, whether they acknowledge that responsibility or not.
The question is therefore not only: “How do we improve children’s health?”
Perhaps the more useful question is: “How do we create homes and communities in which the healthier choice becomes the normal choice?”
Children do not grow up inside nutrition guidelines. They grow up inside families. If we want to help shape healthier children, we must help create healthier families, and build healthier villages around them.
