The living food diet, also known as the raw food diet or raw veganism, has garnered attention for its potential health benefits and environmental impact. This article delves into the principles of the living food diet, its purported advantages, potential drawbacks, and practical considerations for those considering this dietary approach.
What is the Living Food Diet?
The living food diet centers on consuming foods in their natural state, with minimal processing or cooking. A food is typically considered raw if it has never been heated above 104-118°F (40-48°C) or subjected to refining, pasteurization, pesticide treatment, or other forms of processing. Instead, the diet emphasizes preparation methods such as juicing, blending, dehydrating, soaking, and sprouting.
While predominantly plant-based, some variations of the living food diet may include raw eggs, dairy, or, less commonly, raw fish and meat. Proponents often discourage the use of supplements, asserting that the diet provides all necessary nutrients.
Types of Living Food Diets
Within the realm of living food diets, several variations exist:
- Raw Vegan: This approach consists primarily of unprocessed, plant-based foods that are either entirely raw or heated at very low temperatures.
- Raw Vegetarian: This diet focuses on unprocessed, plant-based foods that are heated at very low temperatures, while also allowing for the consumption of dairy and eggs.
- Raw Omnivorous: This involves consuming unprocessed plant-based and animal foods from all major food groups with minimal to no cooking.
All three dietary approaches emphasize the consumption of fruits, vegetables, nuts, seeds, and whole grains.

Purported Benefits of the Living Food Diet
Advocates of the living food diet believe that it offers a range of benefits, including:
- Weight Loss: The emphasis on fresh fruits, vegetables, nuts, and seeds, which are naturally low in calories, can contribute to weight loss. High-fiber foods also promote satiety, potentially reducing overall calorie intake.
- Improved Vitality and Energy: Proponents believe that the diet's focus on nutrient-rich foods can lead to increased energy levels and overall vitality.
- Improvement in Chronic Diseases: Some individuals report improvements in chronic conditions as a result of adopting a living food diet.
- Improved Overall Health: The high intake of vitamins, minerals, and antioxidants from raw fruits and vegetables is believed to promote overall health and well-being.
- Reduced Impact on the Environment: The diet's emphasis on plant-based foods and minimal processing can contribute to a smaller carbon footprint and reduced waste.
- Better Gut Health: Raw produce is generally high in fiber, which feeds the gut microbiome, the community of helpful bacteria and yeasts that live in the gut. A healthy microbiome helps prevent digestive issues such as diarrhea or constipation. It may also boost the immune system and help fight off conditions including heart disease and Type 2 diabetes.
- High Nutrient Intake: Fruits, vegetables, nuts and seeds - the bulk of the raw diet - are high in vitamins, minerals and antioxidants. These types of foods may help prevent diseases such as Type 2 diabetes, some types of cancer and obesity.
- Sustainability: The raw food diet can be beneficial to the environment because it offers less waste and lower greenhouse gases.
- No Ultra-Processed Foods: Research suggests that ultra-processed foods are linked to more than 30 different health problems, including heart disease, Type 2 diabetes and some cancers.
Potential Risks and Drawbacks
Despite the purported benefits, the living food diet also carries potential risks and drawbacks:
- Reduced Calorie Intake: The diet's restrictive nature can lead to a reduced calorie intake, making it difficult to meet daily energy needs.
- Reduced Digestibility of Food: Raw foods can be more difficult to digest, potentially hindering the body's ability to absorb calories and nutrients.
- Decreased Amount of Certain Nutrients and Antioxidants: Cooking can increase the availability of certain nutrients and antioxidants, which may be limited in a raw food diet.
- Unbalanced Nutrient Intake: The diet can be unbalanced, often being excessively high in either fats or fruits to meet calorie needs.
- Potential Nutrient Deficiencies: The diet may be deficient in essential vitamins, minerals, and protein, such as vitamin B-12, vitamin D, iron, calcium and omega-3 fats.
- Increased Risk of Tooth Erosion: The high fruit content of some raw food diets can increase the risk of tooth erosion.
- Menstrual Irregularities and Lower Bone Mass: Some studies have linked raw food diets to menstrual irregularities and lower bone mass, particularly in women.
- Food-Related Illness: Eating a raw diet that includes animal foods can be dangerous. Raw dairy, eggs and meat may contain harmful bacteria such as E. coli, listeria and salmonella that can cause serious illness. Even raw fruits and vegetables can be contaminated with germs, so washing raw produce thoroughly is essential.
- Practical Challenges: It can be difficult to stick to a raw food diet. Family gatherings and restaurants may not have raw options. It’s also difficult to travel because raw foods often need to be kept clean and refrigerated.
Is Raw Food Healthier Than Cooked Food?
A common belief among raw food diet supporters is that eating mostly or all raw food is ideal for human health. However, scientific evidence does not fully support this notion. Research indicates that both cooked and raw foods offer health benefits.
While cooking can decrease certain nutrients, particularly water-soluble vitamins like vitamin C and B vitamins, it can also increase the availability of other nutrients and antioxidants, such as lycopene and beta-carotene. Additionally, cooking helps inactivate or destroy antinutrients in food, such as lectins and phytic acid found in grains and legumes, which can hinder mineral absorption in large quantities. Cooking also destroys harmful bacteria, reducing the risk of foodborne illness.
Practical Considerations for Following a Living Food Diet
For individuals considering a living food diet, several practical considerations are essential:

- Start Gradually: To avoid digestive upset and potential withdrawal symptoms, gradually incorporate more raw foods into your diet.
- Focus on Variety: Consume a wide variety of fruits, vegetables, nuts, and seeds to ensure adequate nutrient intake.
- Proper Food Handling: Thoroughly wash all raw produce to minimize the risk of foodborne illness.
- Supplementation: Consider supplementing with vitamin B-12 and other nutrients that may be lacking in a strict raw vegan diet.
- Consult a Healthcare Professional: Before making significant dietary changes, consult with a healthcare professional or registered dietitian, especially if you have underlying health conditions or are pregnant or breastfeeding.
- Kitchen Skills: You may need to ramp up your kitchen skills. Eating out can be tricky, and if you go organic, you may need to go to specialty stores for a wider selection than your usual grocery store.
- Prep Work: Prep work can be extensive. Many raw food fans become experts at blending and dehydrating foods. Some germinate nuts and sprout seeds.

The Middle Road: Embracing a "Mostly Raw" Approach
While a strict raw food diet may not be suitable for everyone, a modified version, often referred to as a "mostly raw" diet, can be a healthier and more sustainable option. This approach involves:
- Cooked Legumes and Whole Grains: Incorporating cooked legumes and whole grains, such as black beans, lentils, and whole wheat, provides essential protein, vitamins, and fiber that are not safely consumed raw.
- Plenty of Produce: Emphasizing a variety of colorful fruits, vegetables, nuts, and seeds to obtain important nutrients.
- Small Amounts of Animal Products: Including occasional servings of cooked eggs, fish, poultry, and meat, while choosing pasteurized dairy products to minimize the risk of foodborne illness.
- Whole Foods Over Ultra-Processed Foods: Replacing processed snacks with whole food alternatives, such as celery and carrots instead of crackers or chips, and fresh fruit instead of cookies.
