Should a Paleolithic diet be offered at early childhood education and care services?
Supporting Nutrition for Australian Childcare (SNAC) was developed by researchers at the School of Medical and Health Sciences at Edith Cowan University. The website provides guidance and resources about nutrition and healthy eating environments for children’s education and care services, as well as an online community focused on supporting practice. Dr Ruth Wallace and Angela Genoni from SNAC talk to We Hear You about the key elements of a Paleolithic diet and how the diet might impact on children’s growth, development and health.
The idea of offering children Paleo foods – more lean meat and fish and less discretionary foods – may sound like a healthy way to go, but is it? Before you go down that road, let’s stop to consider whether such a diet will give the children you nurture and care for enough energy to grow, play and learn. There is a lot more you should understand about the Paleo way of eating before you offer this at your early childhood education and care (ECEC) service.
What does it mean to be Paleo?
The main principle of following a Paleo diet is to eat the foods our ancestors ate thousands of years ago during the Paleolithic Age. These foods include lean meats, fish, fruit, vegetables, nuts and seeds. Foods that became staples when farming began around 10,000 years ago are not typically included in a paleo diet. For example, grains such as wheat and barley (used to bake bread), pasta and rice, beans and other legumes, dairy products, potatoes and other starchy vegetables, and more recently highly processed foods such as chips, cakes, cookies, processed meats and ready meals (Cordain, 2011).
So can Paleo foods provide enough fuel for children?
Some research has shown that adults following a strict Paleo diet have reported losing weight, lowered blood pressure and other benefits from ‘going paleo’ (Masharani, et al., 2015), since this way of eating typically cuts out added sugars, salt and discretionary foods. While eating more vegetables and fruit is a positive, there is no research showing the diet is beneficial over the longer term (Mellberg, et al., 2014; Genoni, et al., 2016).
Children are a different story as their bodies and brains are growing and developing rapidly. They need a wide range of healthy foods from all five core food groups to ensure a sufficient intake of energy and nutrients to fuel this period of rapid growth and development, and to ensure they remain fit and healthy (NHMRC, 2013). Providing children with foods only from the Paleo diet actually removes two whole core food groups (dairy and cereals/grains), and even some vegetables that are recommended as part of a balanced diet. Most health professionals would not recommend the Paleo diet for young children.
What else should you know?
Eating the Paleo way takes a lot of planning: Since the diet relies heavily on nuts, and many ECEC services are nut-free, children may not consume sufficient energy without the inclusion of nuts at mealtime. It is also likely to blow the food budget as protein sources such as meat and fish are more expensive than vegetables and grains that are the bulk of a healthy balanced diet.
Children will need to find sufficient fuel from other foods: Complex carbohydrates such as whole grains readily provide sufficient energy and B vitamins to allow children to grow and be active. If foods such as rice and wholegrain bread are not provided, children will have to use other key macronutrients for fuel such as protein and fat, which may result in stunted growth, failure to thrive and other nutrient deficiencies (Brown, 2008; Desrosiers, et al., 2018).
Too much meat may be harmful to children’s health: Following the Paleo diet focuses heavily on meat, so children could be eating more unhealthy saturated fat than is recommended (NHMRC, 2013).
Future harms: Teaching children to avoid whole food groups may also lead to disordered eating in later life (Hart, et al., 2014).
Avoiding discretionary foods is a positive aspect of the Paleo diet, but existing guidelines already stipulate that discretionary foods should be limited in early childhood education and care and should not feature on the daily menu. More importantly, there is no research evidence to suggest following a Paleo diet is safe for the health of young children.
To ensure children optimise their growth and development, and have the energy to play and enjoy life, here are some simple, yet healthy tips to follow:
- Offer a wide variety of foods daily from all five core food groups, including lots of different colours and textures.
- Choose nutritious whole foods that have been minimally processed.
- Limit discretionary foods, which are energy dense and nutrient poor, and which displace other nutritious foods important for children’s growth and development.
- Allow children to self-serve at mealtimes from a wide range of healthy foods – this will support social and emotional development, and help children recognise their own hunger cues.
- Be a good role model. Sit with children at mealtimes, share the same healthy food, and offer them gentle encouragement to try foods they are unsure about.
As early years educators, yours is an important role in teaching children about healthy food choices that will enable them to be active and engaged learners, and for long-term health benefits later in life. If you should receive any special dietary requests that are not supported by a medical certificate, do not comply with Element 2.1.3 (food and drinks provided should be in accordance with the Australian Dietary Guidelines), or you are simply not sure about, seek further advice from your service director, or visit the SNAC website.
