Choosing more plant-based foods has become one of the biggest food trends in recent years. Many people believe plant-based products are automatically healthier than traditional foods made from meat or dairy.
While eating more vegetables, fruits, beans, and whole grains is widely recommended, scientists say packaged plant-based alternatives deserve closer attention.
Researchers from the Institute for Optimum Nutrition in London recently carried out the first study to directly compare the ingredient lists of plant-based supermarket products with similar animal-based foods. Their findings were published in Food Additives & Contaminants: Part A.
The team examined 71 matching pairs of products sold in one UK supermarket. Every plant-based item was matched with a similar animal-based product of comparable size and type.
The comparisons included products such as plant milk and cow’s milk, vegan cakes and regular cakes, meat alternatives and meat products, as well as sauces, ready meals, yogurt, and spreads.
After carefully reviewing the labels, the researchers found that plant-based products generally had longer ingredient lists.
Altogether they contained almost twice as many food additives as the matching animal-based foods. They also included more total ingredients and more E-numbers, which are identification codes used for approved food additives in Europe.
The researchers explained that this result is not surprising. Manufacturers often need extra ingredients to copy the taste, texture, appearance, and cooking qualities of meat, milk, or cheese using plant ingredients. These additives can help improve consistency, prevent spoilage, or extend shelf life.
Importantly, the researchers emphasized that more additives do not automatically mean greater danger. All additives found in the products had already met UK food safety standards. The study also did not measure how much of each additive people actually consume or whether the products affect long-term health.
Interest in plant-based eating has grown rapidly around the world. Some people choose these foods for health reasons, while others want to reduce their environmental impact or improve animal welfare.
As supermarkets continue expanding their plant-based ranges, understanding how these products differ from traditional foods becomes increasingly important.
The scientists also pointed out that their study had important limitations. Only one supermarket range was examined, so the findings cannot represent every brand or every country. More studies involving larger numbers of products are needed before broad conclusions can be made.
One important question remains unanswered: how processed are these foods? Many experts believe the degree of processing may be more important than simply counting additives. A diet based mainly on whole plant foods may differ greatly from one based mostly on highly processed plant-based alternatives.
Looking at the findings as a whole, the study does not suggest people should avoid plant-based diets. Instead, it highlights the difference between whole plant foods and manufactured meat or dairy substitutes.
People can still enjoy the benefits of plant-based eating by focusing on beans, vegetables, fruits, nuts, seeds, and whole grains while using processed alternatives in moderation if they choose.
After reviewing the evidence, the study offers a valuable first look at ingredient differences but does not answer whether these products are healthier or less healthy.
Future research needs to examine many more supermarkets and determine whether additive levels, food processing, and long-term health outcomes are connected. Until then, reading food labels and choosing minimally processed foods remains sensible advice for most people.
