Plant-Based Diets and Healthy Aging

By Kirsten Maxwell March 17, 2023 17 mins read 94 Views

A plant-based diet promotes healthy aging and reduces the risk of chronic diseases. It also may help slow the decline in cognitive function, according to a new study.

The study was compiled by researchers with the pro-plant-based Physicians Committee for Responsible Medicine, who reviewed clinical trials and epidemiological studies related to aging. It found that aging increases the risk for noncommunicable chronic diseases, but healthful diets can promote healthy aging and mitigate the global burden of disease.

Antioxidants

A diet high in antioxidants has been linked to a lower risk of heart disease, cancer, and diabetes. Antioxidants ward off free radicals, which are atoms with unpaired electrons.

Free radicals are produced naturally in the body and also form from pollution, smoking, and exposure to ultraviolet (UV) rays. Antioxidants counteract these by donating their own electrons, thus protecting healthy cells from damage.

Vitamins C, E and beta-carotene are all powerful antioxidants. However, one of the most important antioxidants in your body is glutathione, which is found in high concentrations in spinach.

A diet high in antioxidants helps to prevent oxidative stress, which is an imbalance between the production and accumulation of oxygen-reactive species. Oxidative stress leads to the onset of diseases like cancer, metabolic disorders and atherosclerosis.

Anti-inflammatory compounds

When your body is exposed to something foreign--a microbe, plant pollen, chemical or other--it responds with an immune response that triggers a process called inflammation. This inflammatory reaction is a necessary part of protecting you from truly dangerous invaders, but sometimes inflammation goes on too long without being directed at a real threat.

Chronic inflammation is a leading cause of many serious diseases, including heart disease, diabetes, dementia and cancer. It can also be the root cause of aches and pains.

A diet rich in anti-inflammatory compounds has been linked to a reduced risk of these diseases. One way to do this is by incorporating a variety of colorful vegetables, fruits and whole grains into your diet.

In addition, anti-inflammatory foods contain nutrients that help protect the arteries, thereby reducing your risk for heart disease. Examples include vitamin E, omega-3 fatty acids and oleocanthal, a compound found in olive oil.

Dietary fiber

Dietary fiber is a key component of plant-based diets and healthy aging. It can prevent or relieve constipation, lower cholesterol and help you maintain a healthy weight. It also helps reduce your risk of diabetes, heart disease and some cancers.

It’s found mainly in fruits, vegetables, whole grains and legumes. The Academy of Nutrition and Dietetics recommends 25-35 grams of fiber daily for adults.

Soluble fiber dissolves in water to form a gel-like substance that can help lower your blood sugar and cholesterol. It’s found in foods like oats, berries, peas and beans.

Other types of dietary fiber include hemicellulose, lignin and pectin. They are classified on the basis of their water solubility or fermentability, as well as on the degree to which they can be metabolized by the gut microbiota.

Vitamin C

Vitamin C is a powerful antioxidant and is found in many fruits and vegetables. It is a very important component of your body's defense system and can help prevent conditions like high blood pressure, gallbladder disease, certain cancers, and atherosclerosis.

While getting adequate amounts of this nutrient from your diet is best, vitamin C supplements may also be beneficial for preventing these diseases and other health problems. However, high doses of vitamin C have been associated with some negative side effects in healthy people, such as kidney stones and digestive upset.

A plant-based diet, especially one that incorporates a variety of colorful fruits and vegetables, is an effective way to promote healthy aging and reduce the risk of chronic diseases. A new study suggests that following a plant-based diet can cut your risk of disease by almost 50% and may even help you live longer.

Frequently Asked Questions

Can you get enough proteins on a plant-based food?

Yes, you can get enough protein on a plant-based diet. You can get amino acids from legumes, nuts, seeds and grains to help build muscle and keep you healthy. Tofu and other soy products contain all the essential amino acids that your body can't make but must obtain from food. If combined with legumes, vegetables such as spinach, kale and other grains, these veggies can provide the necessary protein for proper nutrition. Plant-based protein are better for long-term satisfaction and support longer-lasting satiety. Additional nutrients such as omega-3 fatty acids can be added to plant-based diets through the addition of flaxseeds (chia seeds), walnuts, and hemp seeds.

What are the drawbacks of meat made from plant-based sources?

The main disadvantage of plant-based meat is the lack of essential vitamins and minerals found in animal proteins. Plant-based meat is lower in certain essential amino acids, vitamin B12, and heme iron, all found in higher concentrations in animal protein sources. Because of the large amount of sodium needed to preserve them, some plant-based proteins have higher sodium levels than real meat. Online and in-store purchases of quality vegan products can prove more expensive and more time-consuming. Vegan alternatives might require more work during cooking, and may take longer to prepare.

What are some alternatives to meat protein?

Protein is an essential part of a healthy diet. You can find it in both animal and plant-based foods. The most common plant-based sources of protein include legumes and nuts, seeds, grains, tofu and tempeh, beans and lentils, seitan, wheat gluten, and hemp seeds. High levels of antioxidants in many vegetables and fruits can help reduce inflammation. Some dairy substitutes, such as almond or oat milk, are fortified with proteins, making a great plant-based alternative to cow's milk. Alternatives such as pumpkin seeds or nutritional yeast can give dishes a richer, cheesier flavor than animal-based ones. They also provide more micronutrients. Many vegan protein powders that can be used in smoothies and shakes can provide additional nutrition, without the need to consume animal products.

Is there any athlete or celebrity who advocates a plant-based diet for their health?

Yes, celebrities and athletes are big supporters of a plant based diet. This includes Kyrie Irving, a NBA player, and Lewis Hamilton, Formula 1 World Champion. Also, Natalie Portman, Meghan Trainor, and Kenneth Farrow, the NFL's running back. Each of them have chosen the vegetarian/vegan lifestyle because it was best for them and have had impressive achievements in their respective fields, whether they are athletes or artists. Actress Alicia Silverstone went as far as even writing a book about her experience with the vegan lifestyle titled Kind Diet. Professional tennis player Novak Djokovic has credited his career successes to his unconventional habit of eating primarily organic vegan foods during competitions; his stats have drastically improved since he adopted this regimen. The significant characteristics that all four professional athletes have identified include a greater energy level, faster healing from injuries, and improved health and wellbeing. Plant-based diets can prove to be a useful tool in improving athleticism.

Is a plant-based diet harmful?

While many people have reported health benefits from switching to a plant-based lifestyle, there are risks involved in any type of diet. People who are transitioning to a plant based diet should be careful about their vitamin and mineral intake. Inadequate nutrition can lead to nutritional deficiencies and adverse health effects. In addition, living a vegan/plant based lifestyle may mean that you are unable to consume the valuable protein found in eggs and dairy. This could affect your muscle maintenance. To avoid any potential health problems or nutritional pitfalls, people who follow plant-based diets need to adjust their diets in accordance with their needs.

Supplements are necessary when you eat a plant based diet.

While a healthy, balanced plant-based diet can provide all necessary nutrients for good health and well-being, you should supplement with certain micronutrients to correct any potential deficiencies. Vitamin B12, which is important for cognitive and nervous system health, is typically only found in animals. Supplemental forms of this vitamin might be helpful to vegetarians and vegans. Additionally, many foods on a plant-based diet lack enough iron and zinc, two minerals important for healthy metabolism, red blood cell production, tissue growth, and repair. The normal functions of the body, including controlling inflammation and maintaining proper brain function, are also affected by omega 3 fatty acids. Because of their biochemical nature, many plant-based foods don't contain enough omega-3s. Supplementation could help restore the delicate balance. Calcium is essential for strong bones. However, it can be found in small amounts through foods like broccoli and kale. If you are struggling to meet your daily calcium needs from food, you might consider supplementation. Before you start taking any new supplements, it is a good idea to double-check with your doctor.

Can a plant-based diet reduce the risk of chronic diseases?

Because of its many environmental and health advantages, plant-based eating is growing in popularity. This diet consists of eating mostly fruits, vegetables, whole grains and legumes as well as nuts and seeds. It also eliminates or substantially reduces animal protein such as meat and dairy products. There are many benefits to a plant-based approach to eating, such as improved heart health and digestive health, energy levels, decreased stress hormones, potential environmental protection, and increased energy. A plant-based diet can provide enough protein. There are many excellent alternatives to protein.
