Raw Vegan Diet: Sustainable Or Sensational?

The raw vegan diet is a subset of veganism, which involves eating only plant-based foods that are either completely raw or heated at temperatures below 104–118°F (40–48°C). While some people may choose this diet for ethical or environmental reasons, most do it for its purported health benefits, such as weight loss, improved heart health, and a lower risk of diabetes. However, is this diet sustainable?

There are several challenges and potential health risks associated with a raw vegan diet. Firstly, it can be difficult to obtain all the necessary vitamins and minerals, leading to potential deficiencies in vitamin B12, calcium, vitamin D, iodine, and iron. Secondly, the diet tends to be low in calories and protein, which can result in weight loss and may impact muscle and bone strength. Additionally, the high consumption of fruits and natural sugars can increase the risk of tooth decay. Furthermore, the restrictive nature of the diet may lead to difficulties in feeling full and finding suitable dishes when dining out. From a practical standpoint, the diet can be time-consuming and expensive due to the need for frequent meals and specialised preparation methods.

While a raw vegan diet may offer some health benefits, it is important to carefully consider the potential challenges and risks associated with this restrictive dietary approach.

Weight loss

A raw vegan diet can be an effective way to lose weight. It is high in fibre and low in calorie density, which helps with weight loss and maintaining a lower weight.

One study found that people who followed a raw vegan diet for over 3.5 years lost around 22-26 pounds (10-12 kg). The participants with the highest percentage of raw foods in their diet also had the lowest body mass indexes (BMIs). Another study found that men who stuck with a raw food diet long-term (three-plus years) lost an average of about 22 pounds, while women lost about 26 pounds.

A raw vegan diet is generally rich in fruits and vegetables, which are low in calories. The diet is also high in fibre, which helps you feel fuller for longer. In addition, the diet excludes high-calorie processed foods like chips, cookies, and fast food.

However, there is a risk of losing too much weight on a raw vegan diet. In one study, around 14-25% of participants became underweight. In the same study, about 30% of women under 45 experienced amenorrhea, or the cessation of menstruation, possibly due to low body weight.

A raw vegan diet can be an effective way to lose weight, but it is important to monitor your weight and overall health to ensure you are getting adequate nutrition and maintaining a healthy weight.

Health benefits

A raw vegan diet is believed to be the healthiest as it preserves all the nutrients and enzymes found in food that could otherwise be destroyed by high cooking temperatures. Here are some of the health benefits of a raw vegan diet:

Incredibly Nutritious

Fruits and vegetables are packed with vitamins, minerals, and antioxidants, and are a good source of fibre, which is important for digestive health. Nuts and seeds are a great source of protein and healthy fats, which can help to improve heart health and reduce inflammation.

Weight Loss

A raw vegan diet is typically very low in calories as it is based mostly on fruits and vegetables. It is also often high in fibre, which can help to keep you feeling full and satisfied throughout the day. In one study, people on a raw vegan diet for three and a half years exhibited very low body mass indexes.

Cardiovascular Health

Observational studies show that vegan diets, especially those rich in fruits, vegetables, nuts, and whole grains, can be great for promoting cardiovascular health. A raw vegan diet is naturally low in cholesterol and saturated fats and high in fibre, antioxidants, and omega-3 fatty acids, which are important for maintaining a healthy heart and preventing heart disease and stroke.

Reduced Risk of Type 2 Diabetes

A raw vegan diet is naturally high in fibre and low in sugar, two key factors in preventing the onset of diabetes. It is also packed with nutrients and antioxidants that can help keep blood sugar levels stable.

Increased Energy Levels

A raw vegan diet is rich in various nutrients that have been shown to increase energy levels, including B vitamins, iron, magnesium, and protein.

Improved Skin Health

A raw vegan diet can do wonders for your skin! By eating plenty of fresh fruits and vegetables, you’ll be getting all the vitamins and minerals your skin needs to stay healthy. Plus, the antioxidants in plant-based foods can help protect your skin from damage, and the low fat and sugar content can help keep your skin looking its best.

Lower Risk of Cancer

Some research suggests that a raw vegan diet can help protect against cancer, especially colon cancer, due to its high fibre and antioxidant content, and its ability to reduce inflammation.

Promotes Body Detoxification

When you eat a raw plant-based diet, you are consuming more fibre, which helps to bind and eliminate toxins from the intestine. Plants also contain phytochemicals that protect cells and promote detoxification enzymes in the liver. Raw vegan foods are also rich in water, which helps flush out toxins and byproducts that can build up in the body.

Nutritional deficiencies

A raw vegan diet may be deficient in vitamin B12, vitamin D, calcium, iodine, and iron. Vitamin B12 is one example of a nutrient that is naturally lacking in a raw vegan diet. A deficiency in this vitamin can lead to anaemia, nervous system damage, infertility, heart disease, and poor bone health. A 2019 study found that 38% of participants following a raw food diet were deficient in vitamin B12.

Raw vegan diets may also be low in protein, often providing less than 10% of your total daily calories. Protein is important for preserving muscle mass, especially during periods of low-calorie intake and weight loss.

Additionally, the diet may be low in calories, making it challenging to meet your daily calorie needs. This can lead to unintended weight loss, which may further increase the risk of nutritional deficiencies.

To avoid nutritional deficiencies, it is important to carefully plan your diet and consider adding supplements to ensure you are getting all the necessary nutrients.

Food preparation

For example, grains and legumes are often included in a raw vegan diet but must be soaked or sprouted before eating. This process can be time-consuming and requires planning. Additionally, raw vegans may use food dehydrators, juicers, and blenders to prepare their meals.

A raw vegan diet typically consists of foods that are eaten uncooked or heated at temperatures below 104–118°F (40–48°C). This means that cooking methods such as roasting, steaming, frying, sautéing, boiling, pressure-cooking, searing, broiling, and grilling are avoided.

• Breakfast could be a smoothie made with frozen bananas, fresh berries, spinach, and raw almond butter, or smashed avocado with minced cilantro and diced tomatoes over raw bread made from nuts and seeds in a dehydrator.
• Lunch could be a chopped broccoli salad with red cabbage, unroasted sunflower seeds, dried fruit, and raw vegan cheese, dressed with cold-pressed olive oil, lemon juice, fresh garlic, and raw tahini.
• Dinner options include raw vegan tostadas, raw pad thai with almond butter sauce and zucchini noodles, or raw vegan enchiladas with salsa and nut-based "meat".
• Dessert options include no-bake key lime pies or raw vegan brownies.
• Snacks could include grapes, trail mix with dried fruit and raw nuts, or homemade energy bites made with dates.

It is important to note that a raw vegan diet may not provide all the necessary nutrients, so supplementation may be required to avoid deficiencies.

Sustainability

A raw vegan diet is a subset of the vegan diet. It involves eating only plant-based, raw, and unprocessed foods. Raw vegans do not heat, cook, or process the food they eat. The diet is considered "raw" if the food has not been exposed to temperatures higher than 104–118 °F (40–48 °C).

Environmental Sustainability

Some people follow a raw vegan diet for ethical and ecological reasons. The diet is considered environmentally sustainable because it is plant-based and avoids animal products, which have a higher environmental impact.

Financial Sustainability

A raw vegan diet may not be financially sustainable for everyone due to the cost of ingredients and equipment. Fresh, organic produce can be expensive, and some preparation methods, such as dehydrating, chopping produce, juicing, and sprouting, can be time-consuming.

Long-term Sustainability

A raw vegan diet may not be sustainable in the long term due to its restrictive nature. The lack of cooked grains and legumes can make it challenging to get enough calories, and the limited food choices may make it difficult to stick to the diet. Some people may also find it socially isolating.

Health Sustainability

A raw vegan diet can be challenging to maintain due to the risk of nutritional deficiencies, particularly vitamins B12 and D, calcium, and iron. It may also lead to a reduced intake of protein, vitamin D, and iodine. These deficiencies can have negative health consequences, such as tooth decay, irregular menstrual cycles, and weaker muscles and bones.
