What is the aim of this study?

ShinDig stands for 'Sheep milk nutrient bioavailability and digestive comfort'. We're trying to find out how sheep's milk is digested compared to cow's milk and whether the process is different in people who are dairy intolerant.

We’re looking at the different effects two milk products have on gut comfort, digestion and metabolism in women aged 18 - 35, and measuring the digestive and metabolic response after the women drink each type of milk.

Why is this study important?

Lots of people report digestive problems after having dairy, but not all of these people are intolerant to the lactose in milk. Instead, sensitivity to dairy might be caused by other components in milk, proteins and fat.

Sheep's milk has different major proteins and fats compared to cow's milk. These proteins and fats are digested differently, which might affect how well milk is tolerated, and how the body is able to use the nutrients in milk.

This study will help us understand if people who usually have trouble with milk digest and tolerate sheep's milk differently from cow's milk.
