Is a vegan diet really better for you?

4 January 2019

When you compare a plant-based diet to a meat and dairy diet, there are three areas where you’ll notice big differences – money, health, and environmental impact. We’ve looked at each of these areas to see if following a vegan diet really can make a difference.



A vegan diet can also make a massive difference to your health. Eating plant-based food doesn’t mean that you’ll miss out on any protein, calcium or other vital nutrients – you just have to be careful to look for natural sources of these.

Research has linked vegan diets to lower blood pressure and cholesterol, and lower rates of heart disease. Scientists have also found that there are fewer cases of type two diabetes with people following a plant-based diet and that it can even reverse type two diabetes. It could also prevent some types of cancer.

A common myth is that a vegan diets lacks protein and could leave you less physically fit. But this couldn’t be further from the truth – in fact, vegans tend to have improved fitness levels, they recover quicker and are less likely to suffer injuries. Many well-known sports stars have moved to a plant-based diet and this hasn’t affected their performance at all, including Serena Williams, David Haye, Lewis Hamilton and Jermaine Defoe.

As if these health benefits weren’t enough, a plant-based diet can help you lose weight – animal products are higher in fat, so they tend to be high in calories too.



There’s no denying that the lowest carbon diet is a vegan one. Even without cutting out dairy and eggs, cutting meat out of your diet can reduce your carbon footprint by a third.

A recent study found that the carbon emissions of a meat-heavy diet (someone who eats more than 3.5 ounces of meat a day – or about one chicken breast) produce around 15.8 pounds of carbon dioxide a day. In comparison, a vegan diet produces 6.4 pounds of carbon dioxide a day – that’s less than half the amount of carbon.

If you’re trying to cut your carbon footprint when it comes to food, check out the Eat Low Carbon website – it has a huge variety of meals featured on it, and tells you the carbon footprint of every single one – helping you to make greener decisions with your food.



It’s a common misconception that eating vegan is super expensive – but that couldn’t be more wrong. The most expensive parts of a meal tend to be the meat and dairy, so by cutting those out you could do your bank account a favour.

We looked at some typical foods and their vegan alternatives to see if going plant-based really is going to really break the bank.

All of the prices are correct as of December 2018.

Vegan baking can be slightly more expensive if you have to buy more specialised ingredients, but in general the price difference between making plant-based and meat and dairy based meals isn’t huge. When you add the costs up over a week, you could see some serious savings.


Going vegan can make a huge difference to your bank account, your health and your environmental impact – even if it’s just for a couple of days a week. There are plenty of great resources to help you switch to a plant-based diet – check out our guide to going vegan, as well as The Vegan Society and Veganuary’s websites.
