I am glad to be able to speak in this debate and hope that what I say will provide a different kind of insight into the debate on childhood obesity.
I am a great enthusiast for breastfeeding. Breast milk has many exceptional qualities, the most obvious being that it is exactly the right thing for infants to be eating. In the beginning, there is the double cream of breast milk, colostrum, which appears before a baby is even born in preparation for those first feeds. The milk that comes thereafter changes and adapts over time as the baby’s needs change. Breast milk has everything that a baby needs and, taken directly from source, it has the advantage of being at the correct temperature. It is easily absorbed by the infant gut. It is a miracle of nature.
What breastfeeding contributes to this debate is the impact that it can have on reducing childhood obesity. An excellent study was pulled together by UNICEF a few years ago called, “Preventing disease and saving resources: the potential contribution of increasing breastfeeding rates in the UK”. The report analysed data from many studies to ensure that there was a sound scientific basis for the claims that it made. Although I accept that giving precise figures and modelling on this is difficult, the UNICEF report estimates that:
“A modest increase in breastfeeding rates could result in a reduction in childhood obesity by circa 5%. If this was the case, the number of obese young children would fall by approximately 16,300, and annual health-care expenditures would reduce by circa £1.63 million.”
That would be no mean contribution. Breastfeeding starts babies off on the right track and, with the accompanying health benefits, such an increase could result in a generation of healthier babies and young people.
The Government should bear that in mind and ensure that services to promote, protect and support breastfeeding are well maintained. This is too important to be left to the good will of the wonderful network of voluntary organisations across the country. It needs to be an identified priority of this Government. The newly formed all-party parliamentary group on infant feeding and inequalities, which I established this week with colleagues from across the House, aims to examine the matter further. We will consider the issues of inequality, because there are multiple deprivation issues, with lower rates of breastfeeding in deprived communities.
What is less well known about infant formula is the specific contents of that product. It takes a complex chemical process to produce formula that involves either dry blending or wet mixing and spray drying, in which cow’s milk is treated with added lactose or other carbohydrates, vegetable and other oils, vitamins and minerals. According to the First Steps Nutrition Trust, the current regulations require infant formula and follow-on formula to have an energy content of between 60 kcal and 70 kcal per 100 ml. Those figures are based on the energy content of breast milk, but, as I mentioned earlier, breast milk composition changes in response to the baby as it grows. Breast milk also has more unsaturated fats than cow’s milk and the fats in infant formula tend to come from the vegetable oil. If anyone has an interest in finding out more about this, I recommend that they seek out the “Infant milks in the UK” report that is produced by the First Steps Nutrition Trust. The level of detail is fascinating.
There are differences between the growth curves of breastfed and formula-fed babies, with the formula-fed babies gaining more weight in the first year. Some studies suggest that that may, in part, contribute to childhood obesity. Pressure is also put on mothers to ensure that their baby is gaining the correct amount of weight. We should consider how formula milk is delivered. I have heard many people describe how many millilitres of formula their baby has drunk at any given time, comparing and contrasting this with others. There is an expectation of how much is normal.
There is a risk in the making up of formula milk, because one must ensure that the correct dosage of powder is dissolved in the water. If this is not done accurately, there is a risk of babies being overfed or, indeed, underfed. The risk of that is far lower for breastfed babies, although I admit that I could only really tell how much breast milk my babies had by the amount that they both threw up all over me. There is not really any other way of telling.
