In recent years, the popularity of plant-based diets has surged, especially since the pandemic. Many have turned to these diets with the belief that they’re making healthier choices for both their bodies and the planet. But as with any trend, it’s essential to dig a little deeper. Are all plant-based options as healthy as they seem, or are we being misled by clever marketing? A recent study published in The Lancet sheds some light on this very question, revealing that ultra-processed plant-based foods may be as harmful as their non-plant-based counterparts.
You’ve probably seen them in supermarkets—vegan sausages, plant-based nuggets, and dairy-free milks. These products are often hailed as healthier alternatives to traditional animal products. But, according to the study, these ultra-processed versions can actually increase the risk of cardiovascular disease (CVD) and mortality, negating many of the benefits we typically associate with a plant-based diet. It’s a shocking revelation, especially for those who switched to plant-based diets hoping to reduce health risks like heart disease.
The problem lies in the level of processing. Just like their meat-based counterparts, ultra-processed plant-based foods are loaded with additives, and high levels of salt, fat, and sugar—all things that contribute to health issues like dyslipidemia (an abnormal amount of lipids in the blood) and hypertension. As Eszter Vamos, one of the study’s authors, points out: “While ultra-processed foods are often marketed as healthy, they are linked to poor health outcomes.” The buzzwords ‘plant-based’ and ‘vegan’ don’t automatically equate to healthy, especially when those foods have undergone significant industrial processing.
This raises a crucial question: if plant-based diets can include such unhealthy foods, are they truly the beacon of health they’re often touted as?
Nutritional Deficiencies and Health Risks
Another concern with plant-based diets, even those that steer clear of ultra-processed foods, is the potential for nutritional deficiencies. Vitamins D, B12, calcium, and zinc, which are abundant in animal products, are harder to come by in plant-based diets. Without careful attention to nutrition, vegans and vegetarians can risk deficiencies that may lead to serious health problems over time.
Studies have also highlighted a potential increase in the risk of haemorrhagic strokes in vegetarians and vegans compared to meat-eaters. While this is still being researched, it suggests that the plant-based diet’s health benefits are more complex than we’ve been led to believe. It’s not just about cutting out meat; it’s about making informed choices and ensuring you’re still getting the right nutrients.
Rethinking Ultra-Processed Foods
The key takeaway from these studies isn’t to give up on plant-based diets altogether. Rather, it’s a reminder to be cautious of ultra-processed foods, regardless of whether they’re plant-based or not. A diet rich in whole, minimally processed foods—fruits, vegetables, legumes, and grains—remains one of the best ways to support long-term health.
In contrast, consuming heavily processed foods—whether plant-based or animal-derived—comes with similar risks, undermining the very benefits many seek from a plant-based lifestyle.
Is the Grass Greener on the Other Side?
There’s also an alternative to consider. The traditional Japanese diet, for instance, offers a balanced approach to health without giving up animal protein. It emphasises whole grains, vegetables, and fish while avoiding processed foods. This diet has been linked to lower rates of CVD and longer life expectancy, without the need for ultra-processed substitutes. It might just be a gentler path to health for those unsure about diving fully into the plant-based trend.
At the end of the day, it’s essential to remember that not all plant-based foods are created equal. Being mindful of how processed your food is could be the difference between a healthy diet and one that falls short of its promises.
This discussion serves as a timely reminder: don’t be swayed by labels alone. “Plant-based” doesn’t always mean “healthy.” So, next time you’re choosing between a vegan sausage and a whole grain salad, consider what’s really going into your body. It might just be a game-changer for your health.
