A raw food diet consists of mostly uncooked, unprocessed, and organic foods. Foods included in the diet are fruits, vegetables, nuts, seeds, sprouted grains, legumes, and sometimes raw animal products like meat, fish, eggs, and dairy. The diet is likely to cause weight loss but makes it difficult to meet nutritional needs. Cooking food can decrease certain nutrients, but it also increases the availability of other nutrients and antioxidants and kills bacteria. The raw food diet is not recommended for pregnant women, young children, seniors, or people with weak immune systems.

What You'll Learn
Raw fruits and vegetables
A raw food diet is composed of mostly or completely raw and unprocessed foods. Raw fruits and vegetables are a staple of a raw food diet, along with nuts and legumes.
A raw food diet can be beneficial for weight loss since raw foods are usually low in calories and high in fibre, which helps you feel full for longer. However, it can be challenging to get enough calories and certain nutrients, like protein and some vitamins, on a raw food diet. For example, it can be difficult to get enough vitamin B12, iron, calcium, and omega-3 fats, which are mainly found in meat, eggs, and dairy. A long-term raw food diet may also lower levels of "good" cholesterol and raise levels of homocysteine due to a lack of vitamin B-12.
Some common raw food recipes include "rawnola," a raw version of granola made from walnuts, pecans, dates, flaxseed, chia seeds, and old-fashioned oats, typically served with a variety of colourful fruits. Raw green smoothies are another popular option, with common ingredients including bananas, kale, spinach, and blueberries.

Unprocessed foods
A raw food diet is composed mostly or entirely of unprocessed, uncooked foods. It is often called raw veganism, as it is usually plant-based, but some raw food diets may also include raw animal products.
The raw food diet is made up mostly of fruits and vegetables, nuts, and seeds. Grains and legumes are often permitted but usually need to be soaked or sprouted before eating. Common methods for preparing raw foods include making "rawnola" (a raw version of granola made from nuts, dates, seeds, and oats) or raw green smoothies.
Some people on a raw food diet may also consume raw dairy, eggs, meat, or fish. However, raw animal products can be dangerous as they may contain harmful bacteria such as E. coli, Salmonella, and Listeria. The cooking process kills these bacteria, so eating raw animal products can increase the risk of foodborne illness.
It is important to note that a raw food diet can make it difficult to meet your nutritional needs. It may be challenging to get adequate protein, vitamin B12, iron, calcium, omega-3 fatty acids, and vitamin D. While a raw diet may have some benefits, such as weight loss and improved heart health, it is important to ensure it is well-planned and provides all the necessary nutrients.

Raw animal products
When it comes to raw animal products, there are a few key components that form the basis of a raw diet. Firstly, raw meat is a fundamental part of this diet. This includes a variety of raw, fresh, and preferably organic muscle meat, such as beef, chicken, turkey, lamb, and rabbit. These meats provide essential amino acids, which are the building blocks of proteins, and are crucial for maintaining and repairing body tissues, like muscles, skin, and organs.
In addition to muscle meat, including organ meat is vital. Organ meats, also referred to as offal, include items like liver, kidneys, heart, and brain matter. These are nutrient-dense foods, rich in vitamins and minerals that are often deficient in modern diets, such as B vitamins (especially B12), iron, zinc, and essential fatty acids. For example, liver is an excellent source of vitamin A, which supports eye health and immune function. It's important to source these organs from healthy, pasture-raised animals to ensure optimal nutrient profiles.
Raw, fresh, and whole fish is another important component. Fish provides high-quality protein and is an excellent source of omega-3 fatty acids, which are anti-inflammatory and support heart health, cognitive function, and healthy skin and coat. Examples include salmon, sardines, mackerel, and herring. It is important to rotate between different types of fish to minimize the risk of exposure to high levels of mercury, which can be toxic, and to ensure a varied intake of nutrients.
Raw, shelled, or unshelled eggs are also beneficial. They are a complete protein source, meaning they contain all the essential amino acids, and are rich in vitamins and minerals, including choline, which supports brain health, and selenium, a powerful antioxidant. Including eggshells, preferably from organic sources, provides additional calcium for bone health.
Lastly, raw animal products also incorporate raw animal bones, preferably ground or crushed, from non-weight-bearing bones like necks and ribs. These provide calcium and other minerals, as well as natural fats that contribute to a healthy diet. Chewing on raw bones also promotes dental health by helping to scrape away plaque and tartar buildup. It is important to never feed cooked bones as they can splinter and cause internal damage. Always supervise your pet when they are consuming raw bones to ensure safety.

Nutritional deficiencies
A raw food diet is mostly made up of uncooked, unprocessed, and organic foods. It includes fruits, vegetables, nuts, seeds, sprouted grains, legumes, and sometimes raw animal products like meat, fish, eggs, and dairy.
However, this diet is nutritionally inadequate and may lead to deficiencies. Here are some essential nutrients that may be lacking:
Protein
Protein is essential for various bodily functions, including muscle repair and growth. It is typically found in animal products like meat, fish, eggs, and dairy, which are usually cooked. While some plant-based sources of protein exist, such as legumes and nuts, the bioavailability and digestibility of protein from these sources may be lower compared to animal sources.
Vitamin B12
Vitamin B12 is crucial for red blood cell formation, neurological function, and DNA synthesis. It is naturally found in animal products, especially meat, fish, eggs, and dairy. Since the raw food diet is predominantly plant-based, it may be deficient in this critical vitamin.
Iron
Iron is essential for red blood cell formation and transporting oxygen throughout the body. Heme iron, the type found in animal products, is more easily absorbed than non-heme iron, which is present in plant sources such as legumes and spinach. The raw food diet's emphasis on raw plant foods may result in lower iron absorption.
Calcium
Calcium is necessary for bone health, nerve function, and muscle contraction. Dairy products are the richest source of calcium, but they are typically consumed cooked or pasteurized. While some plant sources like leafy greens contain calcium, the amount and absorbability are lower compared to dairy.
Omega-3 Fatty Acids
Omega-3 fatty acids are essential for heart health, brain function, and reducing inflammation. The best sources of omega-3s are fatty fish like salmon, sardines, and anchovies, which are typically cooked. While there are plant sources like flaxseeds and walnuts, the type of omega-3 they provide (ALA) has limited conversion to the more critical forms (EPA and DHA) found in animal sources.
In conclusion, while the raw food diet may offer certain benefits, it is important to be mindful of potential nutritional deficiencies. To ensure adequate nutrient intake, it is advisable to consult a healthcare professional or dietitian before starting this or any restrictive diet.

Preparation methods
A raw food diet consists of mostly or completely raw and unprocessed foods. It is often plant-based, with fruits, vegetables, nuts, seeds, legumes, and grains forming the bulk of the diet. Some people also include raw eggs, dairy, meat, and fish.
To prepare raw foods, there are several techniques you can use:
- Soaking: Soaking is a common technique used for legumes, grains, seeds, and nuts. It helps to reduce anti-nutrients like phytates, which can interfere with nutrient absorption. Soaking also makes these foods softer and easier to digest.
- Dehydrating: Dehydrating is a method of preserving foods by removing their moisture content. A dehydrator is a device that blows hot air across the food to remove the moisture. Dehydrated foods can have a longer shelf life and can be a convenient snack option.
- Juicing: Juicing involves extracting the liquid and nutrients from fruits and vegetables. Fresh fruit and vegetable juices are a popular way to consume a large amount of nutrients in a raw form. Juicing can also be a way to make smoothies or add flavour to other dishes.
- Blending: Blending or pureeing raw ingredients can create smoothies, soups, or sauces. Blending helps to break down the food into a more easily digestible form and can also aid in the absorption of nutrients.
- Sprouting: Sprouting is the process of germinating seeds, legumes, or grains. It increases the nutrient content, making vitamins and minerals more available for absorption. Sprouting also makes these foods easier to digest.
- Chopping: Chopping or mincing raw ingredients can make them easier to eat and can also aid in the release of certain nutrients.
It is important to note that the preparation methods used should not involve heating the food above a certain temperature, typically considered to be between 104°F (40°C) and 118°F (48°C). This is because the raw food diet is based on the belief that heating food destroys important enzymes and reduces nutrient content.
