SACN Carbohydrates and Health Report

The Scientific Advisory Committee on Nutrition (SACN) was asked by the Department of Health and the Food Standards Agency to examine the latest evidence on the links between consumption of carbohydrates, sugars, starch and fibre and a range of health outcomes (such as heart disease, type 2 diabetes, bowel health and tooth decay) to ensure the government’s position on consumption was up-to-date. In addition to the main report, you can read the SACN press release In its review of the evidence, SACN found that: High levels of sugar consumption are associated with a greater risk of tooth decay. The higher the proportion of sugar in the diet, the greater the risk of high energy intake. Drinking high-sugar beverages results in weight gain and increases in BMI in teenagers and children. Consuming too many high-sugar beverages increases the risk of developing type 2 diabetes. In light of these findings, SACN recommends that: Free sugars should account for no more than 5% daily dietary energy intake. The term free sugars is adopted, replacing the terms Non Milk Extrinsic Sugars (NMES) and added sugars. Free sugars are those added to food or those naturally present in honey, syrups and unsweetened fruit juices, but exclude lactose in milk and milk products. The consumption of sugar-sweetened beverages (e.g. fizzy drinks, soft drinks and squash) should be minimised by both children and adults.

SACN Carbohydrates and Health Report

Carbohydrates are a major source of energy in the diet. Classified according to their chemistry, carbohydrates can be divided into sugars (monosaccharides and disaccharides), polyols, oligosaccharides (malto-oligosaccharides and non-digestible oligosaccharides) and polysaccharides (starch and non-starch polysaccharides). However, this classification does not allow a simple translation into nutritional effects since each class of carbohydrates has overlapping physiological properties and effects on health. Carbohydrates can also be classified according to their digestion and absorption in the human small intestine. Digestible carbohydrates are absorbed and digested in the small intestine; non-digestible carbohydrates are resistant to hydrolysis in the small intestine and reach the large intestine where they are at least partially fermented by the commensal bacteria present in the colon. There is no universal definition of the term ‘dietary fibre’; broadly speaking, it refers to some or all of the constituents of non-digestible carbohydrates and may also include other quantitatively minor components (e.g.lignin) that are associated with non-digestible carbohydrates in plant cell walls.  

Wholegrains

With all the choice available these days it can be easy to forget just how good regular foods can be. Take wholegrain breads for example. They contain carbohydrates, fiber, iron and B vitamins. They're real superfoods that can keep you going for longer and take care of your digestive system.

Sugar Reduction: Responding to the Challenge

In ‘Sugar Reduction: Responding to the Challenge’, PHE is calling on charities, non-governmental organisations (NGOs), academics, businesses, retailers and consumers to work together to reduce the amount of sugar we eat as a nation. By analysing dietary data and discussing food habits with stakeholders, we have identified a range of areas that need exploring further. PHE already runs successful marketing campaigns designed to promote healthy living. To build on this, we also want to look at the way foods are being advertised to children, financial measures that relate to sugar sweetened drinks, food procurement across the public sector and education and training. Today, PHE received a draft report from the Scientific Advisory Committee on Nutrition (SACN): ‘Carbohydrates and Health’. PHE is particularly interested in SACN’s research because it is clear that the nation is consuming more sugar than the UK’s current recommendations. Diets high in sugar can contribute to excess calorie intake, which can lead to weight gain and obesity.
