More people are cutting out meat in favour of plant-based diets for ethical, environmental and health reasons. But not all plant-based foods - either vegetarian or vegan - are as healthy as we think they are. In fact, some are classed as ultra-processed foods, which have been linked to heart disease and cancer.
Following a plant-based diet is a great way to eat more fruits, vegetables and pulses. These foods contain lots of nutrients that are good for us - as well as plenty of fibre to keep our digestive systems healthy.
Vegetarians, vegans, and pescatarians - those that only eat fish - also avoid eating red meat or processed meat like sausages and bacon, which contain more nitrates, salt, and fat and have been linked to cancer. And of course, there are environmental benefits to eating less meat, including lowering carbon emissions.
Eating more plants and less meat also reduces your chance of developing health problems like heart disease. Studies show that people on plant-based diets have a lower likelihood of heart attack and stroke compared to those on omnivorous diets - eating meat and vegetables.
However, research also shows a plant-based diet isn’t always healthy. Imitation meats or meat substitutes - such as vegan nuggets, sausages, and burgers or fake chicken pieces and ready meals - are sometimes classified as ultra-processed foods.
These are convenience foods that contain additives like sweeteners, salt, and artificial flavours but contain few nutrients.
Why are some plant-based foods ultra-processed?
Reema Pillai, a registered dietitian at Dietitian Fit, says that the rise in vegetarianism and veganism has led to a demand for meat alternatives in recent years.
She says that while these may seem like a great way to help reduce meat consumption - if that is your aim - it is also important to keep in mind that many of these alternatives would be classed as ultra-processed foods.
"Often, these foods contain additives such as emulsifiers, texturisers and colours," she explains. "They may also be classed as high added salt, fat or sugar foods.
It’s important to look at the overall processing of a plant-based product to understand its nutritional profile and to ensure it is actually a more nutritious option."
There’s no denying that eating less meat - and particularly red meat - can come with health benefits. But ultimately, meat and fish in their purest form are unlikely to be heavily processed because they are a single ingredient food.
When we try to recreate them using ingredients like soya, bean or pea protein, we have to process them to make them look and taste palatable. This means adding salt, sugar, fat and other additives to increase taste and prolong their shelf-life. However, we assume they’re healthy because of the 'plant-based' label.
Should we be eating plant-based alternatives?
Often, vegan or vegetarian meat alternatives or ready meals contain less saturated fat than animal-based products. So ultra-processed or not, you’ll be eating less saturated fat and that’s a good thing. However, any ultra-processed foods still contain more sugar, salt and other additives to provide flavour or texture.
Eating ultra-processed plant-based foods every so often is unlikely to cause any health problems. But overall - as is the case with any ultra-processed foods - it is probably better to eat them in moderation.
How to eat less vegan or vegetarian ultra-processed foods
Pillai advises you pay attention to the nutrient content of convenience foods when at the supermarket. Look at the ingredients list - if it’s very long and contains things you’ve not heard of, it’s probably very processed.
It’s not easy to eat healthily all the time when you’re busy. But cooking meals or sauces in batches and freezing them can make things easier when you’re tired or don’t have much time.
Lentils, beans or other pulses like chickpeas can bulk up a meal easily without the need for fake meats. Garlic, herbs and spices can make a dish tasty without additives like sweeteners or artificial flavours.
Pillai says: "Overall, whole foods that are plant based, are considered the most beneficial to our health, such as fruits, vegetables, grains, pulses, unprocessed soy, nuts and seeds, rather than vegan products which have undergone a high level of processing."

Thinking about going vegan? Here's how to do it healthily
Once the preserve of hippies and activists, veganism has now hit the mainstream. Forgoing meat, dairy and eggs is more popular than ever. Even beloved UK bakery chain Greggs has added a vegan sausage roll to its product line. It's undoubtedly great that people are taking a more ethically-conscious approach to the big shop, but what nutrients could vegetarians and vegans put themselves at risk of losing out on? And how can you approach animal-free consumption in a healthy way? We ask the experts.

A vegan diet improves heart health, according to a study of identical twins
An increasing number of people are turning vegan to improve their health as eating less meat is known to lower the risk of heart disease and stroke. However, diet studies are often limited by factors like genetic differences. Now, a groundbreaking study involving identical twins suggests that a vegan diet can improve cardiovascular health in just eight weeks.
