Are you vegetarian, vegan, reducetarian, flexitarian, or planetarian? Because of all the hype around new diets that are better for the planet and our health, the team at Real Foods decided that it was time to give the lowdown, so you can determine the best vegetarian diet for you.
Maybe you think that vegetarianism has only just reached a mainstream audience? In 2015, the celebrity chef and healthy eating campaigner Jamie Oliver publicly declared, “I’m eating meat as little as possible now. I’m nearly vegetarian.”
While there are more variances of vegetarianism today, the concept is far from new. Many people in countries around the world – for reasons of culture, religion or social status – have chosen a vegetarian diet as standard.
As the world looks at how we can all collectively reduce our environmental impact and mitigate the challenges of climate change, more experts are recommending plant-based diets.
The facts about meat consumption
- Animal farming is responsible for around a 30% loss in global biodiversity due to deforestation, pollution, and climate change. Likewise, it’s also a leading air and water pollutant, posing health risks to local communities
- It takes over 7,000 litres of water to produce a single pound of meat. In contrast, it takes less than 750 litres of water to produce a pound of potatoes or wheat (Source: National Geographic)
- Every year, over 70 billion factory farmed animals are killed for the meat industry. The meat industry alone accounts for 20% of global greenhouse gas emission (Source: United Nations Food and Agriculture Organization)
- Overfishing of our oceans, freshwater rivers and fishery exploitation could create fishless oceans by the year 2050 (Source: Science Journal, 2006)
- Furthermore, if plant crops were fed directly to humans instead of as animal feed for the meat industry, there would be a 70% increase in the world’s food supply. This could feed the one billion undernourished people four times over. (Source: United Nations Food and Agriculture Organization).
There are pros and cons of every single vegetarian diet – so, we’re going to give you the lowdown, in a nutshell!
Vegetarian diets & vegetarianism
What is a vegetarian diet?
A vegetarian diet is one that does not include any meat, poultry, or fish.
What can vegetarians eat?
There are three sub-types of vegetarian diets:
- Lacto-ovo vegetarian diet, where meat, fish, poultry are avoided but dairy and eggs are eaten. This is the predominant vegetarian diet for most communities in Europe and North America.
- Lacto-vegetarian diet, where meat, fish, poultry and eggs are avoided but dairy products are eaten. This is the most popular vegetarian diet for many communities in Asia.
- Ovo-vegetarian diet, where meat, fish, poultry and dairy products are avoided but eggs are eaten.
What are the benefits of a vegetarian diet?
Individuals choose to adopt vegetarianism for health, religious and spiritual reasons, and for ethical and environmental issues.
- Spiritual reasons for being vegetarian: Many religions, such as Jainism, Hinduism, and Buddhism have their roots in a vegetarian lifestyle as it supports the concept of unity with other sentient beings. Many spiritual leaders such as priests and monks refrain from eating meat believing that it is impure, unnatural, and engenders aggression. Some religions abstain from eating meat during periods of significant, annual religious events.
- Ethical reasons for being vegetarian: Animal welfare, particularly in mass production.
- Environmental reasons for being vegetarian: Many worry about how livestock production requires more land and is more water and energy intensive than other modes of farming.
- Health reasons for being vegetarian: Public opinion, backed up with research, show that vegetarians can be healthier due to a higher nutritional intake, such as fibre, vitamins and minerals. Studies show that it can reduce your risk of cancer. Also, stabilize your blood sugar level, reduce your risk of diabetes and major cardiovascular problems. It may even aid weight loss. Vegetarians on average weigh 15% less than non-vegetarians, according to Nutrition Reviews, 2006.
Is vegetarianism healthy?
Vegetarianism can be healthy if you eat real foods. However vegetarians who eat a lot of saturated fats and processed, low-nutrient vegetarian food will not benefit. There is also a danger that vegetarians who do not eat a well-balanced diet that includes wholegrains, nuts, leafy green vegetables, and proteins can be deficient in vitamin B12, iron, calcium and zinc.
When did vegetarianism become popular?
Vegetarianism has been around for centuries! It has been recorded in history across the globe, from India to Greece since the sixth century.
By 1839, the word vegetarian popped up in our vocabulary in European society, and today over three million people in the UK adopt a vegetarian lifestyle, which is around 6% of the population.
Where can I get advice about vegetarianism?
British charity The Vegetarian Society was established in 1847 to promote vegetarianism as a form of religious temperance in the modern Western world. The society continues to be a strong advocate and is a valuable source of information.
Vegan diets & veganism
What is a vegan diet?
Discerning vegan consumers require more familiarity with product labelling as to be a true vegan you would need to exclude a range of ingredients such as gelatin, whey, cochineal, casein, lactose, egg white albumen, or carmine, isinglass, shellac, L-cysteine, fish-derived omega-3 fatty acid and animal-derived vitamin D3.
What can vegans eat?
There are four sub-types of vegan diets:
- Wholefood vegan diets, which are the most typical, is a purely plant-based diet compromising of vegetables, grains, nuts, seeds, fruits, and soya products.
- Raw vegan or thrive diets, where followers only eat raw plant-based foods or cook food at temperatures below 48°C.
- Raw til 4 diet, a low-fat vegan diet in which only raw foods are consumed before 4pm.
- Starch solution diet, a low-fat, high-carbohydrate vegan diet that focuses on cooked starches such as potatoes, corn and rice instead of fruit.
What are the benefits of a vegan diet?
Just like vegetarianism, there are many environmental and ethical benefits of a vegan diet. Vegans often advocate for sustainability and are against mass livestock production and factory farming. The vegan community frequently campaigns against fishing, hunting or trapping animals.
Vegans often have lower blood sugar levels, blood pressure and cholesterol, which in turn reduces heart disease, arthritis, Alzheimer’s disease, and the risk of cancer. Veganism can improve kidney function too!
Is veganism healthy?
A vegan diet isn’t always healthy. If you opt to be a “junk food vegan”, then all the health benefits of veganism will disappear.
When did veganism become popular?
The English animal rights advocate Donald Watson, first coined the term vegan in 1944 for vegetarians like himself who abstained from eating animal and dairy products.

Flexitarian, Reducetarianism & Planetary diets
What is the reducetarian (planetary) or flexitarian diet?
Many flexitarians limit processed and heavily sugared foods, opting for natural, healthier whole foods. It is not a diet per se, more a lifestyle; you are a casual vegetarian who is predominantly vegetarian but chomps on the occasional meat dish when the urge is there or at social events where meat is served.
When did flexitarian and planetary diets become popular?
Flexitarian was allegedly coined by the American dietician Dawn Jackson Blatner in 2009.
Flexitarian has increased in popularity in the last two decades. Notably, the flexitarian movement received hard epidemiological evidence at the beginning of 2019 when a group of 37 leading scientists were brought together for the EAT-Lancet Commission on Food, Planet, Health to reach a scientific consensus that defines a healthy and sustainable diet.
These scientists were looking for a diet that could work for 10 billion people, the number of people estimated to be alive in the year 2050.
They studied the most sustainable diets on the planet. The result of the commission highlighted a broken global food system.
“The food we eat and how we produce it determines the health of people and the planet, and we are currently getting this seriously wrong. We need a significant overhaul, changing the global food system on a scale not seen before in ways appropriate to each country’s circumstances.” – Professor Tim Lang, City, University of London
The published EAT-Lancet Commission report highlighted that, in order to prevent a global food crisis and improve global health:
- North Americans and Europeans need to reduce their red meat intake by about 80%
- East Asia needs to cut back on fish
- Africa needs to stop eating so many starchy vegetables, such as potato and cassava.
- Globally, we need all need to eat 15 times the current intake of nuts and seeds, and halve our food waste.
Because of this groundbreaking report, the flexitarian diet has been overshadowed with a more scientifically-backed reducetarian diet known as the planetary diet, which has set manageable, actionable goals.
The report’s authors highlight that, if the entire world adopt the planetary diet we could stop 11 million deaths that have been caused by unhealthy diets annually.
What can flexitarians and reducetarians eat?
The Mediterranean diet of continental Europe and the traditional Okinawa diet of Japan probably resemble the recommended planetary diet the most.
The planetary diet is more prescriptive than flexitarianism, recommending the following portion sizes per day:
- Red meat (beef, lamb, pork): 14 g
- Chicken: 29 g
- Fish: 28 g
- Whole grains (bread, rice, pasta): 232 g
- Starchy vegetables (potatoes, cassava): 50 g
- Dairy: 250 g
- Eggs: 13 g
- Vegetables: 300 g
- Fruits: 200 g
- Legumes: 75 g
- Sugar: 31 g
- Oils: 50 g

Largely plant-based with vegetables making up more than half of every meal, the planetary diet allows for an average of 2,500 calories a day and, with no exotic ingredients needed, provides wiggle room for individual tastes and budget.
What are the benefits of a reducetarian diet?
A flexitarian or reducetarian diet is beneficial because they are convenient and flexible, and you don’t have to stick to strict rules every day. If you feel like you can’t give up meat entirely then this is a good middle-ground for you. Recipes are also simple to follow.
While the definition of flexitarian/reducetarian can vary, there are studies that substantiate that these diets share many the same health, ethical and environmental health benefits of other vegetarian diets.
Environmental benefits: A 2014 study on the sustainability of plant-based diets by the American Society for Nutrition highlights that plant proteins use 11 times less energy during their production compared with animal protein. A 2016 review revealed that individuals on a typical Western diet who then switch to a flexitarian diet are believed to decrease greenhouse gas emissions by 7%.
Health benefits: According to a 2003 report by the International Journal of Obesity, even semi-vegetarians weigh less than fully-fledged carnivores.
Are reducetarian diets healthy?
Reducetarian and flexitarian diets are healthy as long as you are eating well-balanced, nutritious meals and cut out processed foods, so that you avoid the risk of nutritional deficiencies.
Where can I get advice about reducetarian diets?
You can find a useful list of resources from The Reducetarian Foundation including access to The Reducetarian Cookbook, which is endorsed by the British singer-songwriter of The Beatles’ fame, and vegetarian advocate Sir Paul McCartney.
Fruitarian diets & Fruitarianism
What is a fruitarian diet?
A fruitarian diet is one that primarily focuses on eating raw fruit, making up around 75 per cent of the food you eat.
What can fruitarians eat?
What are the benefits of a fruitarian diet?
Fruitarians advocate that the diet is as close to the natural foraging diet of our hunter-gatherer ancestors, prior to the onset of widespread agriculture.
Is fruitarianism healthy?
Fruitarian diets are restrictive and so you should speak to a doctor before beginning a predominant fruit-based diet.
Some nutritionists and doctors argue that fruitarians do not receive a fully balanced diet and can it cause severe nutritional deficiencies if not managed properly. Some fruitarians use supplements to prevent malnourishment.
Signs of nutritional deficiency on a fruitarian diet include feeling tired, being anaemic, having poor metabolism and immunity, and getting brittle bones from osteoporosis due to a low calcium intake.
While you can lose weight on a fruitarian diet, if you stop the diet for any reason you may have more long-term weight gain due to the high sugar content. Sugar can also speed up tooth decay.
Fruitarianism is not suitable for diabetics or pre-diabetics or if you have any pancreatic or kidney disorders.
When did fruitarianism become popular?
The word fruitarian was first coined in1893 and has gained momentum from those seeking an alternative plant-based diet in the last two decades.
Steve Jobs, founder of the supertech company Apple, was an advocate of this diet.
