Do humans need dairy? Here’s the science

TheConversation: A lot of people will have already made up their mind about whether humans need dairy in their diet and will be thinking that the answer is obviously “yes” or obviously “no”. But nutrition is based on science not opinion – so, here’s the latest research on the matter. Milk is an interesting foodstuff. The sugar in it is called lactose and lactose requires a chemical or enzyme called lactase to allow it to pass across the walls of the gut into the blood stream. When we are babies, we all produce plenty of the lactase enzyme which allows us to absorb our mother’s milk. In populations where milk consumption has been historically low, such as Japan and China, most children will have stopped producing lactase soon after weaning and – producing almost entire populations that may be unable to absorb the lactose in milk – this we call “lactose intolerance”.

High-fat dairy products linked to reduced type 2 diabetes risk

Lund: Consumption of high-fat yoghurt and cheese are linked to a reduction in the risk of type 2 diabetes by as much as a fifth, according to new research from Lund University in Sweden. High meat consumption, on the other hand, is linked to a higher risk.
