A raw food diet consists of at least 70 percent uncooked and unprocessed foods. Most people on a raw food diet eat only plant-based foods, making it a type of vegan diet. However, some people eat raw animal products, such as raw meat, eggs, and dairy. The diet is believed to offer a range of health, environmental, and financial benefits. However, it can also be risky and negatively impact your health in the long term. To follow a raw food diet, you must ensure that you are still getting the vitamins and minerals your body requires.

What You'll Learn
The benefits of a raw food diet
A raw food diet has several purported benefits, which have attracted many people to this way of eating. The diet is based on the idea that cooking destroys the nutrient content of food and that raw foods are more "live" and natural.
Firstly, a raw food diet is likely to lead to weight loss. This is because raw foods are low in calories and fat, and high in fibre. The high fibre content of a raw food diet may also improve digestion, with insoluble fibre helping to move food through the gut and soluble fibre feeding the good bacteria in the intestines.
Secondly, a raw food diet may improve heart health. This is due to its focus on fruits and vegetables, which are linked to lower blood pressure and a reduced risk of heart disease and stroke. The diet is also rich in nuts, seeds, and legumes, which may further lower the risk of heart disease by improving blood cholesterol levels.
Thirdly, a raw food diet may reduce the risk of type 2 diabetes. This is again due to the high levels of fruits and vegetables in the diet, which are linked to lower blood sugar levels and increased insulin sensitivity.
It is important to note that a raw food diet may not be suitable for everyone and can be difficult to follow. It may also be lacking in certain nutrients, such as protein and some vitamins, and can increase the risk of foodborne illness, especially if consuming raw animal products.

What foods to eat
A raw food diet consists of mostly uncooked and unprocessed foods. The diet is mostly plant-based, with raw fruits and vegetables as staples. It may also include nuts, seeds, legumes, sprouted grains, fermented foods, and raw sweeteners. Some people also include raw animal products, such as meat, fish, eggs, and dairy.
To add variety to a raw food diet, some preparation techniques can be used, such as soaking, sprouting, dehydrating, fermenting, juicing, and blending. For example, you can make dehydrated wraps using large leafy greens, such as collard leaves, kale, or romaine lettuce. Smoothies and salads are also popular meals on a raw food diet, as they can include a variety of fruits, nuts, seeds, and nut butter.
It is important to note that a raw food diet may be challenging to maintain in the long term due to the risk of nutritional deficiencies. Cooking can increase the availability of certain nutrients and antioxidants, while also destroying harmful bacteria and other undesirable compounds. Therefore, it is recommended to include a combination of cooked and raw foods in the diet to ensure adequate nutrition.
Additionally, it is important to be mindful of food safety when consuming raw foods. Some foods may not be safe to eat uncooked, and there is a risk of food poisoning from raw animal products and even raw fruits and vegetables. It is always advisable to consult a healthcare professional before starting any new diet, especially if you have specific health concerns or conditions.

What foods to avoid
A raw food diet is made up of mostly or completely raw and unprocessed foods. It is based on the belief that cooking food destroys its nutrients and natural enzymes, which are essential for digestion and fighting chronic diseases. However, to ensure you are getting adequate nutrition on a raw food diet, there are certain foods you should avoid.
Firstly, it is important to avoid highly processed foods. This includes packaged or manufactured foods, which are typically high in salt, added sugars, and unhealthy saturated fats. Instead, focus on fresh, organic produce. Additionally, grains and legumes, while permitted on a raw food diet, should be soaked or sprouted before consuming. This helps to reduce antinutrients like lectins and phytic acid, which can interfere with mineral absorption.
It is also crucial to exercise caution when consuming raw animal products, such as meat, fish, eggs, and dairy. Unpasteurized dairy, in particular, poses a risk of Listeria infection, which can be especially dangerous for pregnant women. According to the Centers for Disease Control (CDC), uncooked animal products are the most likely to cause food poisoning. Therefore, if you choose to include raw animal products in your diet, ensure that they are sourced safely and handled properly to minimize the risk of foodborne illnesses.
Furthermore, certain plant-based foods, such as sprouts, raspberries, green onions, and lettuce, carry a higher risk of food poisoning when consumed raw. To mitigate this risk, it is essential to wash these foods thoroughly and handle them with care. Overall, it is recommended to consult a healthcare professional or dietitian before starting a raw food diet to ensure it meets your individual nutritional needs and does not pose any health risks.

How to prepare raw food
Preparing raw food can be time-consuming, as recipes often require lots of soaking, sprouting, dehydrating, blending, peeling, and chopping. The diet allows for chopping and blending, but excludes any food heated beyond a certain temperature, usually between 104° to 118°F (40° to 48°C), though some sources state 120°F (49°C). The only heating allowed is with a dehydrator, which blows hot air across food.
Raw food diets are typically composed of fruits, vegetables, nuts, seeds, legumes, and grains. Some people also include raw eggs, dairy, fish, and meat. However, it is important to note that some foods, such as grains and legumes, are often consumed after being soaked or sprouted. Olives, for example, are usually too bitter to eat raw, so people on a raw food diet can eat olives if they are sun-cured.
Some common methods for preparing raw foods include:
- Breakfast: "Rawnola" is a raw version of granola made from walnuts, pecans, dates, flaxseed, chia seeds, and old-fashioned oats, served with various fruits and optionally juices, nut milk, or cold-pressed oil.
- Snack: Raw green smoothies can be easily customized.
- Wraps: Large leafy greens, such as collard leaves, kale leaves, or romaine lettuce leaves, can be used as wraps.

The risks of a raw food diet
A raw food diet typically consists of uncooked and unprocessed foods, including fruits, vegetables, nuts, legumes, sprouted grains, and sometimes raw animal products, such as meat, fish, eggs, and dairy. While proponents of the diet claim that it improves health and well-being, there are several risks associated with this dietary approach. Here are some of the key risks of a raw food diet:
Risk of Foodborne Illness: Eating raw foods, especially animal products, increases the risk of foodborne illness. The Centers for Disease Control (CDC) states that uncooked animal products are the most likely to cause food poisoning due to harmful bacteria such as E. coli, Salmonella, and Listeria. Even raw fruits and vegetables can carry a risk of food poisoning, although it is lower compared to raw animal products.
Nutrient Deficiencies: A raw food diet can make it challenging to meet all your nutritional needs. Cooking helps release valuable nutrients, such as lycopene and beta-carotene, and improves the absorption of certain minerals like zinc, iron, calcium, and magnesium. By avoiding cooked foods, you may not get enough of these essential nutrients. Additionally, a raw vegan diet may lead to vitamin B12, vitamin D, or calcium deficiencies.
Digestive Issues: Cooking helps break down fibers and cellular walls, making nutrients more available for absorption. In contrast, a raw food diet may cause digestive problems, such as gas or cramping, due to the high fiber content and the body's difficulty in breaking down certain raw foods.
Reduced Food Choices: A raw food diet significantly reduces the types of foods you can eat. It can be challenging to find a variety of raw, unprocessed foods that meet your nutritional needs and taste preferences. This restriction may lead to a monotonous diet and potentially impact your social life, as dining out or sharing meals with others may become more difficult.
Cost: Adopting a raw food diet can be expensive due to the need to purchase large quantities of fresh, organic produce. The specialized nature of the diet may also require additional expenses, such as investing in juicers, blenders, or dehydrators to prepare raw-friendly meals.
While a raw food diet may offer some potential benefits, it is important to carefully consider the risks outlined above. It is always recommended to consult with a healthcare professional or registered dietitian before making significant dietary changes to ensure your nutritional needs are met and to avoid potential health complications.
