Children 10–18 years

Grandparents can help fight childhood obesity

Grandfather fishing with girlParents and Grandparents can greatly influence the environments that children grow up in and many of the experiences that they have.

Research is now showing that the food preferences that children develop are determined by a combination of both environmental and genetic factors.

For instance there is evidence that genetics affect such things as appetite, the speed of eating, responsiveness to feelings of fullness (satiety) and even the enjoyment of food. However the environmental factors, that also play an important role in modelling eating behaviours, need consideration(1).

Fighting obesity in children is a family affair

In 2021, 68% of New Zealand adults and 31% of children are overweight and obese. So being overweight is becoming accepted as the new norm in many OECD countries.

“Wake up” to obesity

Research in the Netherlands has found that the majority of parents failed to recognise overweight or obesity in their 5 and 11-year-old children. Children with normal weight were considered by their parents as a little too light. Overweight children were regarded as normal weight and obese children were considered normal or a little too heavy. This underestimation of overweight may impair a parents motivation to seek help.(2,3)

Unfortunately, as fat gathers around the abdomen, the function of the organs found here (the liver, pancreas and gallbladder) that normally process fat and sugar, becomes impaired.  This causes the fat and sugar levels in the blood to rise, thereby increasing the risk of developing diseases such as diabetes,  heart disease, some forms of cancer, and respiratory illness.

As children gain weight they experience more fatigue, they feel sluggish and find it difficult to concentrate at school. Obesity leads to problems with bone density as their growing bones struggle to bear their extra body mass. They may also experience a loss of confidence and mood fluctuations as their weight increases.

Grandparents can offer support to parents when they recognise that feeding problems may exist in their children. Also they can help to educate the young about the importance of good nutrition to physical and mental development and disease prevention.

Grandparents need respect

Grandparents are special people who have much to offer the world. No longer considered “old” grand parenting today means being vital, up-to-date, active and involved. (4)

The relationship a grandparent has with their own child changes as they watch them become parents. Where once they may have “jumped right in” and assisted their child to cope with life’s challenges, grand parenting is a time to stand to one side, offering  them support  and wisdom when it is needed.

Grandparents never stop learning

If providing food for young children it is important that Grandparents take the time to learn about current nutritional guidelines as feeding practices for children have changed dramatically over the past 10-20 years: Here are some prime examples:

  • Breast feeding is best and women need to be encouraged and supported to keep feeding for as long as possible.
  • The introduction of solids is usually delayed until 6 months unless there is a food allergy in which case some foods can be introduced by 4-5months on consultation with the child’s doctor or dietitian.(5)
  • When introducing milk,  modified or whole milk is best up until 2 years; then light blue® or mega milk®. Trim® or calcium trim® is preferable from 5 years on. For more information read Lea’s article Milk matters
  • An allergy to cow’s milk, depending on severity may necessitate that a child requires a modified formula to drink for the first 12-18mths and may then move onto soy or rice milk as guided by their paediatrician.
  • Fat is important for the development of brain and nerve tissue however this is available in sufficient amounts in staple foods such as meat and cheese without the addition of butter 62% of which is saturated fat. Polyunsaturated fats in the form of margarines and vegetable oils, fish, avocado and nuts are healthier sources of fat for children.
  • Food allergies need to be respected and Grandparents are advised to avoid trying to set up food challenges if their grandchildren (with known allergies) come to stay. Be guided by the child’s parent or their doctor as to any foods that they should avoid.
  • Trying new foods are to be encouraged. However children should not be pressured to “clean up their plates” if they are feeling full as over-riding a child’s sense of fullness can make it hard for them to regulate their own food intake as they get older. Obviously be guided by a child’s growth rate and for more information read Lea’s article “Who controls feeding the mother or the child” as well as “Picky eating affects all age groups”.
  • Sweetened soft drinks and fruit juice are fine for the odd special occasions but if drunk on a regular basis can be a major source of calories, sugar and salt. Milk and water are kinder to their teeth and weight. For alternative beverage ideas read Lea’s article “What are our children drinking?”
  • Take care with party “treats”. Grandparents need to find other ways to “treat” children rather than feeding them  lollies, crisps, cakes and biscuits when they come to visit If you are needing party ideas refer to Lea’s article “Party plans for children
  • Takeaway foods such as eating fish and chips may have been a “treat” when Grandparents  were young and now and again they do no harm. However there are now much healthier takeaway meals for children to eat. Try hamburgers, subway®, sushi, souvlaki, pizza or Asian meals or for other ideas read  Lea’s articles Healthy ideas for family takeaway meals.

Keeping children active is essential to family health

Being healthy is no longer just about weight control and fitness. It is about helping to develop a child’s talents, giving them job’s to do, having friends and family and  feeling safe and loved. As their confidence and self esteem grows they learn to value their body and the things they can do.  It is never too late to find new talents or activities to occupy the time.


Cooking can be messy but allows children to have fun as they practice how to weigh, measure and count. While making biscuits and sweets can be helpful if running a stall at school or fund-raising, it is important to teach children how to make every day foods. Creating a salad or pizza, a batch of scones, muffins or loaf of bread can prove to be a lot of fun and much healthier options. For more ideas read Lea’s article “Teach your child to cook for better health”


Taking children to the supermarket or growers markets can be fun for young children and a learning opportunity as help to fill bags of fruit and have the chance to see fruits, vegetables, plants and cheeses  and foods that they may not normally see at home.

Make time to play

Taking children to the park, kicking a ball, rowing (with your help), biking, playing field games, learning to vacuum and clean are all opportunities to encourage children to become more active, to expend energy and learn skills that improve their hand and eye co-ordination. For information regarding activities suitable for different age groups read Lea’s article “Playtime helps combat obesity”.

Develop crafts

Teaching children to knit and sew, to build and make things is a luxury that few parents have time for these days. Grandparents can help to fill this important knowledge gap if they introduce children to  activities such as these. Helping to nourish a child’s creativity not only occupies time more constructively than watching a TV set but also helps them to build fine-motor skills and self esteem as they complete new tasks.

Grow gardens

Children love to grow things so teach them how to plant seeds and to garden. If a Grandparent is unable to attend to their own garden then show them how to grow pots of herbs, carrots or radishes.

Care for animals and the environment

Not all households have pets these days. Teaching children how to care for animals helps them develop empathy for others. A trip to a wildlife park, or aquarium, even simply going to feed the ducks helps children to get out doors. Visiting parks and gardens, taking them fishing or camping can also help children to learn more about their environment and how to respect it.

Children are naturally curious

Grandparents can teach children a lot about history simply by taking them to a museum, an Anzac parade,  historic parks, to the art gallery or library. Plenty of people will teach children how to Google for information but taking time to learn first hand about their environment helps them work with and appreciate reality.

Value time

Time is the biggest “treat” to give to our children and is often in short supply in busy modern families. Taking the time to read stories and play games when they are little, to encourage the development of their talents as they grow, to listen to their success stories and be there in times of need all contribute to creating a healthy environment for them to grow up in.

Lead by example

Children are always watching adults and mimicking their behaviour. So in order to be a “good team leader”, Grandparents need to look after their own health as well. Eating regular meals, taking exercise, developing talents, learning new things and asking for help when needed,  encourages children to do the same.
