1 Isn't yoghurt an ultra-processed, sugar-laden snack that we should avoid buying when we're in the supermarket? The truth is a bit more complicated, and it all depends on the yoghurt. Some do have a high sugar and fat content and offer few other health benefits. But when it comes to yoghurt, they are not the whole story.

2 Let's look at some of the potential benefits. Yoghurt is made by fermenting milk, which produces a number of live bacterial cultures. These helpful bacteria interact with our gut flora and have been associated with better digestive health. It's possible that this could lead to reduced symptoms in people with conditions such as irritable bowel syndrome. It's also been suggested that regularly consuming yoghurt could reduce inflammation and the risk of developing some kinds of bowel cancer. However, many types of yoghurt available in shops are pasteurised, which kills most of the helpful bacteria.

3 As well as providing calcium, B vitamins and phosphorus, yoghurt is high in protein. Protein can be important for muscle development, bone strength, and for controlling our appetites. Again, the choice of yoghurt can be important. Strained, Greek-style yoghurt is thicker than regular yoghurt and is particularly high in protein. 200g contains around double the amount of protein found in 200ml of milk.

4 The effect of fat in yoghurt is more complex. It is high in saturated fat, which could be a risk factor for heart disease. However, some studies suggest that saturated fat from whole milk, can provide beneficial forms of cholesterol, which might protect heart health. However, more research in this area is needed, and current UK government advice is to look for low-fat yoghurt.

5 There are many potential benefits as long as we choose the right yoghurt. Unsweetened Greek yoghurt that retains live bacteria is likely to be the best choice for our health.
