The idea that some people need meat in their diet is a highly contested topic. Meat is a good source of protein, vitamins, and minerals, and can be part of a healthy, balanced diet. However, it is recommended that people do not consume too much red, processed, or fatty meat, as this can lead to health problems. The carnivore diet, which consists entirely of animal products, has been promoted as a way to aid weight loss and improve health. However, there is no reliable research to support these claims, and the diet is considered unnecessarily restrictive and difficult to maintain long-term. Some people may struggle to meet their nutrient requirements on a vegan or vegetarian diet and may need to work harder to obtain all the necessary nutrients or take appropriate supplements. Individual nutrient needs vary, and some people may thrive on a meat-inclusive diet, while others do well without it.

What You'll Learn
Meat as a source of protein, vitamins and minerals
Meat is a good source of protein, vitamins, and minerals, and is considered the most nutrient-dense food on earth. Proteins are the building blocks of the body, essential for growth and development, and are made from amino acids. Meat is a source of "complete proteins", meaning it contains all the essential amino acids the body needs. Lean meats such as chicken, turkey, beef, and pork are excellent sources of high-quality protein and important nutrients like iron and zinc. Red meat is among the best sources of dietary zinc, which is hard to get enough of on a vegan or vegetarian diet. Beef liver is also a good source of preformed vitamin A, which is important for eye and skin health.
Meat also contains vitamin D3, which is more absorbable than its plant-based counterpart, ergocalciferol (D2). Fatty fish, beef organs, and egg yolks are the best sources of vitamin D3. People who don't get enough vitamin D3 from their diet or sunlight may experience negative symptoms like depression, multiple sclerosis, and an impaired immune response.
Meat is also a source of selenium, which is important for immune health. Selenium is becoming harder to obtain from plant sources due to depletion in the soil.
However, it is important to note that a balanced diet with a variety of healthy foods is recommended, as a carnivore diet consisting only of meat, fish, eggs, and small amounts of low-lactose dairy is extremely restrictive and high in fat. It also contains no fiber or beneficial plant compounds and is difficult to maintain long-term.

The restrictive nature of the carnivore diet
The carnivore diet is a highly restrictive diet that consists solely of animal products, including meat, poultry, eggs, seafood, fish, and some dairy products. All other food groups, such as vegetables, fruits, grains, legumes, seeds, and nuts, are excluded. This elimination of entire food groups is a significant departure from the dietary guidelines recommended by organizations like the NHS, which advocate for a balanced diet that includes a variety of nutritious foods from different groups.
One of the main concerns with the carnivore diet is its restrictiveness and the potential for nutrient deficiencies. By cutting out fruits and vegetables, the diet eliminates important sources of vitamins, minerals, fiber, and beneficial plant compounds. This can lead to an increased risk of certain health conditions, such as heart disease, certain cancers, Alzheimer's, and type 2 diabetes. Additionally, the diet is high in saturated fat and cholesterol, which can negatively impact cholesterol levels and increase the risk of heart disease and stroke.
The carnivore diet is also criticized for being difficult to follow long-term due to its lack of variety and strict restrictions. It may lead to food cravings and is not considered a sustainable way of eating. Some people may also experience negative side effects, such as nutrient deficiencies, high cholesterol, and increased risk of certain health conditions. It is especially important for certain populations, such as children, pregnant or lactating women, and those with kidney disease or a history of disordered eating, to avoid this diet due to its potential negative impacts.
While proponents of the carnivore diet claim that it aids weight loss and improves various health issues, these claims are not supported by reliable research. The weight loss associated with the diet is likely due to the initial elimination of calorie-dense, sugary junk foods and the high protein and fat content that helps prevent hunger. However, the restrictive nature of the diet makes it challenging to maintain, and any weight loss may be short-lived as individuals are likely to return to their previous eating habits.

Health benefits and risks of the carnivore diet
The carnivore diet is a highly restrictive diet that consists solely of animal products, including meat, fish, eggs, and small amounts of low-lactose dairy. It is claimed to aid weight loss, improve mood issues, and regulate blood sugar, among other health benefits.
Health Benefits
The carnivore diet eliminates highly processed carbohydrates, which can lead to early benefits such as improved blood pressure, reduced belly fat, and improved cardiovascular health. It is also claimed to aid in the management of type 2 diabetes by improving blood sugar levels. A 2021 study found that most people on the diet experienced a high level of satisfaction, general health improvements, and few adverse effects.
Health Risks
The long-term health implications of the carnivore diet are largely unknown due to a lack of research. However, it is speculated that the diet may lead to nutrient deficiencies, as it eliminates highly nutritious foods like fruits, vegetables, legumes, and whole grains, which contain essential vitamins and minerals. The diet is also high in saturated fat and cholesterol, which may increase the risk of heart disease and stroke. Additionally, processed meats allowed on the diet are often high in salt, which can lead to an increased risk of high blood pressure and kidney disease. The very high protein intake associated with the diet can also lead to impaired kidney function. Furthermore, the restrictive nature of the diet may make it challenging to maintain and can result in food cravings.
While the carnivore diet may provide some initial health benefits, there are significant concerns regarding its long-term sustainability and potential negative health consequences. More research is needed to fully understand the impact of this diet on overall health.

Meat preparation and food safety
Meat can be a good source of protein, vitamins, and minerals. However, it is recommended not to consume too much red, processed, or fatty meat. Meat can be included in a healthy balanced diet, but it is important to prepare and cook it safely.
Meat safety is an important aspect of a meat-inclusive diet. Proper handling, storage, and cooking of meat are crucial to prevent foodborne illnesses, commonly known as food poisoning. Here are some detailed guidelines for meat preparation and food safety:
Cleanliness and Sanitation:
- Wash hands thoroughly before and after handling meat.
- Keep your kitchen and utensils clean. Wash cutting boards, dishes, utensils, and countertops with hot soapy water, especially after they've come into contact with raw meat.
- Use separate cutting boards and utensils for raw meat and other foods to avoid cross-contamination.
- Avoid washing raw meat before cooking, as it can spread bacteria to other surfaces and increase the risk of food poisoning.
Storage and Separation:
- Store meat separately from other foods in the refrigerator or freezer.
- Use airtight containers or sealed plastic bags to prevent meat juices from leaking and contaminating other foods.
- Follow storage guidelines for different types of meat. Some meats can be stored for a week after preparation, while others should be consumed or frozen within a few days.
- Always buy meat before other grocery items to minimise the time it spends outside refrigeration.
Cooking:
- Cook meat thoroughly to kill harmful bacteria. Use a food thermometer to ensure that meat reaches a safe minimum internal temperature.
- For beef lovers who prefer rare meat, stick to steaks, roasts, and chops.
- Poultry, such as chicken, turkey, duck, and goose, including liver, should be cooked all the way through until the juices run clear, and there is no pink or red meat inside.
- Fish should generally be cooked to a minimum internal temperature of 145°F (62.8°C) but can be medium-rare for certain types. Raw fish for sushi should be frozen at -4°F (-20°C) for at least a week to reduce the risk of contamination.
Chilling:
- Refrigerate or freeze meat within 2 hours of cooking or purchasing to prevent bacterial growth.
- Maintain refrigerator and freezer temperatures at 40° F (4° C) and 0° F (-18° C), respectively.
By following these guidelines for meat preparation and food safety, you can significantly reduce the risk of foodborne illnesses and enjoy meat as part of a healthy and balanced diet.
