Plant-based diets have surged in popularity during the past few years. As a result, there is been a boom in demand for plant-based alternatives to favourite foods - including meats, such as sausages and burgers. The plant-based meat alternatives industry is projected to see massive growth over the next few years. But there is still a lot we don't know about these food products - including whether they are as healthy as some may think.

Although many of these products claim to be made primarily from plants, they aren't all that different to other ultra-processed food products. They often contain many similar ingredients - including protein isolates, emulsifiers, binders and other additives - and are made using industrial processing methods, so can be considered an ultra-processed food product.

Plenty of evidence links ultra-processed foods to obesity, type 2 diabetes, cancer and other chronic diseases. This is probably due to a combination of their poor nutritional content, synthetic additives and lack of fibre, which is important for giving a feeling of fullness. These types of foods are also a reason why poor diet has become the world's top cause of death from chronic diseases, as they're readily available, easy to overeat, lack nutrients and now provide around a half or more of the calories consumed in countries such as the US, UK, Australia and Canada.
