Mayo Clinic Diet: Is It Truly Plant-Based?

The Mayo Clinic encourages a predominantly plant-based diet for patients with cancer, which includes whole foods, fruits, vegetables, whole grains, beans, nuts, and seeds. This is supported by the American Institute for Cancer Research and the American Cancer Society. The clinic also recommends a plant-based diet for cancer patients to boost their immune system and lower the risk of chronic diseases. However, it is important to note that the Mayo Clinic does not advocate for a solely plant-based diet, as it can be challenging to obtain sufficient protein, vitamin B12, calcium, iron, and vitamin D from plant sources alone. Thus, the clinic suggests that a balanced approach, including both plant-based and animal-based sources, can be beneficial.

The Mayo Clinic diet is not strictly plant-based

The Mayo Clinic diet is flexible and can include animal products. In fact, it is described as an umbrella term that can encompass a range of eating styles and diets, from vegan to flexitarian. For example, the Mediterranean diet, which includes fish and poultry, is often considered one of the healthiest eating styles and falls under the plant-based umbrella.

The key to the Mayo Clinic diet is striving for minimally processed foods. This includes whole grains, fruits, vegetables, beans, nuts, seeds, herbs, and spices. It is recommended to avoid highly processed items like frozen meals, snack foods, and sugar-sweetened beverages.

The Mayo Clinic diet acknowledges that it can be challenging to shift towards a plant-based diet, especially for those who enjoy the taste of meat or consider it the "main event" of a meal. Therefore, it suggests taking a gradual approach, such as starting with one plant-based meal or day per week.

The diet also emphasizes the importance of planning and ensuring adequate nutrient intake. For example, vitamin B12 and vitamin D may need to be supplemented, and it is essential to talk to a healthcare professional before making any significant dietary changes.

In summary, while the Mayo Clinic diet emphasizes plant-based foods and can include fully plant-based variations, it is not strictly plant-based and allows for flexibility and individual preferences.

The benefits of a plant-based diet

A plant-based diet focuses on eating foods that are primarily derived from plants. This includes fruits and vegetables, nuts, seeds, oils, whole grains, legumes, and beans. It does not necessarily mean that you are vegetarian or vegan and never eat meat or dairy. Rather, it involves choosing more of your foods from plant sources.

The Benefits

Cancer Prevention

A plant-based diet is the only diet that has been consistently proven over two decades to reduce your risk of cancer. Plant foods contain essential nutrients, vitamins, and minerals that help keep your cells healthy and your body in balance so that your immune system can function at its best. Plant-based diets have also been shown to reduce inflammation, which is linked to cancer and other inflammatory diseases like arthritis.

Weight Management

Plant-based diets are high in fiber, which is present in all unprocessed plant foods. Eating a plant-based diet improves the health of your gut, allowing you to better absorb nutrients, support your immune system, and reduce inflammation. Fiber can also lower cholesterol and stabilize blood sugar, aiding in weight management.

Heart Health

Vegetarian diets have been linked to a lower risk of developing coronary heart disease, high blood pressure, and diabetes. Plant-based diets are often higher in fiber and phytonutrients, which are beneficial for heart health. Research has also shown that plant-based diets may lower cholesterol levels and blood pressure, contributing to improved cardiovascular health.

Nutritional Adequacy

Plant-based diets offer all the necessary protein, fats, carbohydrates, vitamins, and minerals for optimal health. Concerns about protein deficiency are unfounded, as plant-based sources such as legumes, lentils, tofu, nuts, and seeds can provide sufficient protein. However, some vegans may need to supplement their diet with vitamin B12 to ensure they receive all the required nutrients.

Environmental Impact

In addition to the health benefits, a plant-based diet can also reduce your environmental footprint.

A plant-based diet offers a variety of health benefits, including cancer prevention, improved weight management, better heart health, and adequate nutrition. It is a sustainable and nutritious way to improve your overall health and well-being.

Getting enough protein on a plant-based diet

Protein is an important macronutrient to keep track of as you age. It can help to muffle hunger and stall age-related losses in muscle, physical function and bone mass. According to Andrew R. Jagim, Ph.D., director of Sports Medicine Research at the Mayo Clinic, it is probably the most undereaten nutrient.

If you follow a plant-based diet, it can be more challenging to reach your protein goals, but it is not impossible. It will require more planning and effort, and possibly a protein powder supplement.

The Dietary Guidelines for Americans recommend that adults eat a variety of proteins that add up to about 50 grams a day, or 10% to 35% of your calories. Another way to calculate your protein needs is to aim for at least 0.8 grams of protein per day for every kilogram of body weight. For example, a person who weighs 165 pounds, or 75 kilograms, should consume 60 grams of protein per day. If you are over 40 or 50, your protein needs increase to about 1-1.2 grams per kilogram, or 75-90 grams per day for a 165-pound person, to prevent sarcopenia and maintain muscle mass. If you exercise regularly, your protein needs are even higher, ranging from 1.1-1.7 grams per kilogram.

Protein-rich plant foods include beans, legumes, lentils, tofu, nuts, seeds, edamame, hummus, quinoa, whole grains, artichokes, asparagus, broccoli, spinach, and soy products like tempeh.

Tips for getting enough protein on a plant-based diet:

• Monitor your protein intake by tracking the grams of protein you consume in a day.
• Distribute protein throughout the day by including one or two servings of protein-rich plant foods at every meal and snack.
• Match high-protein days with workout days.
• Try a protein powder supplement. When choosing one, look for a powder that provides 20 to 25 grams of protein per serving and contains all nine essential amino acids.

Sample plant-based meals containing protein:

• Peanut butter and chia overnight oats (16 grams of protein)
• 1 cup cubed tofu on a salad (20 grams of protein)
• 1 cup steamed edamame (17 grams of protein)
• 1 cup cooked lentils over 1 cup brown rice (23 grams of protein)
• 1 cup cooked lentils over 1 cup quinoa and 1 tablespoon pumpkin seeds (28 grams of protein)

Tips for starting a plant-based diet

A plant-based diet has numerous health benefits, and it can be easy to start and stick to. Here are some tips to help you get started on your plant-based journey:

Understand the Basics

Firstly, it's important to understand the key ingredients of a plant-based diet. This includes minimally processed vegetables, fruits, grains, nuts, seeds, herbs, and spices. There are variations within this diet, such as vegan, vegetarian, and flexitarian. Vegan diets include only plant foods, while vegetarians may also consume dairy and eggs. Flexitarians mostly eat plants but occasionally include meat or fish.

Focus on Whole Foods

When starting a plant-based diet, it's best to focus on whole foods that are not heavily processed. This means choosing natural, unrefined, or minimally refined ingredients. Opt for whole grains, fruits, vegetables, beans, and legumes.

Get Creative with Recipes

There are plenty of plant-based recipes available online and in cookbooks. Experiment with different ingredients and cuisines to find what you like. You can also adapt your favourite recipes by substituting meat with plant-based options like tofu or beans.

Take a Gradual Approach

You don't have to go completely plant-based overnight. A gradual approach can make the transition easier. Start by adding more plant-based meals to your diet, such as going meatless one day a week or making breakfast mostly plant-based.

Ensure Proper Nutrition

While plant-based diets are nutritious, it's important to ensure you're getting all the necessary nutrients. Focus on including a variety of whole foods in your diet to meet your nutritional needs. You may also want to consider taking supplements for vitamin B12 and vitamin D, as these nutrients can be lacking in a purely plant-based diet.

Find Support

Making any dietary change is easier when you have support. Consider finding a friend or family member who can join you in your plant-based journey. You can also seek advice from a registered dietitian or healthcare professional to ensure you're getting the right nutrients.

Plant-based diets and cancer

Plant-based diets are full of fruits, vegetables, legumes, whole grains, beans, nuts, and seeds, with little to no meat or other animal products. Research has shown that a plant-based diet can be an effective way to lower the risk of cancer. In this article, we will explore the benefits of a plant-based diet for cancer prevention and discuss the latest research on the link between plant-based diets and cancer.

The Benefits of a Plant-Based Diet for Cancer Prevention

A plant-based diet is encouraged for cancer patients by the Mayo Clinic. Dr Dawn Mussallem, an integrative health specialist at the clinic, recommends a predominant plant-based diet that is high in fibre. She states that 97% of Americans do not get enough fibre, which is crucial for cancer prevention. The American Institute for Cancer Research and the American Cancer Society also recommend a plant-based diet to reduce cancer risk.

Research has shown that a plant-based diet can effectively lower the risk of cancer. A study by the American Cancer Society found that nearly 25% of overall cancer cases could be prevented with diet and nutrition alone. Plant-based diets are rich in phytochemicals, which are chemicals that protect the body from damage and interrupt processes in the body that encourage cancer production. Additionally, plant-based diets are high in fibre, which has been linked to a reduced risk of breast and colorectal cancer.

The Role of Phytochemicals

Phytochemicals are naturally occurring compounds in plant-based foods that offer a range of health benefits. They work to protect the body from damage, decrease inflammation, and interrupt processes that encourage cancer production. Two of the most beneficial phytochemicals are antioxidants and carotenoids.

Antioxidants

Antioxidants protect the body from damage caused by radiation, viruses, and exposure to other chemicals. They neutralise damage-causing processes and help restore cells. Antioxidant-rich foods include dark chocolate, apples, avocados, artichokes, red cabbage, tea, coffee, nuts, and grains.

Carotenoids

Carotenoids are fat-soluble compounds found in carrots, sweet potatoes, squash, spinach, apricots, green peppers, and leafy greens. They are highly pigmented and have been linked to a reduced risk of heart disease, cancer, macular degeneration, and cataracts. Carotenoids include beta carotene, lycopene, and lutein.

The Importance of Fibre

Plant-based diets are high in natural fibre, which has been shown to reduce cancer risk and moderate insulin levels. A study found that young women who ate a high-fibre diet were 25% less likely to develop breast cancer later in life. Additionally, for every 10 grams of daily fibre intake, the risk of colorectal cancer decreases by 10%. Fibre also promotes the growth of healthy bacteria in the digestive tract, which can help reduce inflammation and improve overall colon health.

Incorporating a Plant-Based Diet

Shifting to a plant-based diet can be gradual and does not have to be an all-or-nothing change. Here are some tips to incorporate more plant-based foods into your diet:

• Start your day with a healthy breakfast of whole grains such as oatmeal, buckwheat, or quinoa, along with fruit.
• Experiment with meatless meals, such as meatless Mondays, and try new recipes.
• Use meat as a condiment rather than the main dish.
• Increase the amount of beans, lentils, or vegetables in your recipes to reduce the amount of meat.
• Fill half of your plate with fruits and vegetables at lunch and dinner.

A plant-based diet offers a variety of health benefits and can be an effective way to lower the risk of cancer. By incorporating more plant-based foods into your diet, you can improve your overall health and reduce your cancer risk. However, it is important to note that more research is needed to fully understand the link between plant-based diets and cancer.
