Plant-Based Power: Dieting For Athletic Performance

A plant-based diet for athletes is one that is high in carbohydrates, low in fat, and rich in vitamins, minerals, and antioxidants. It can support or improve athletic performance, as it provides all the nutrients needed for training and competition.

A plant-based diet has been linked to various benefits for athletes, including improved heart health, performance, and recovery. It can lead to a leaner body mass, as plant-based foods generally have a higher water content, lower fat content, and higher fibre content. This reduced body fat can result in increased aerobic capacity and improved endurance.

Plant-based diets are also associated with improved recovery due to their high content of antioxidants, which neutralise free radicals produced during exercise. Additionally, these diets have been shown to reduce markers of inflammation in the blood, which is beneficial as chronic inflammation may hinder recovery.

A plant-based diet can also positively impact an athlete's energy levels, blood pressure, and endurance. It provides sufficient protein to build and maintain muscle, with beans, soy milk, nuts, seeds, and soy products being good sources.

Some well-known athletes who follow a plant-based diet include Venus Williams, Novak Djokovic, Lewis Hamilton, and Carl Lewis.

A plant-based diet is high in carbohydrates, low in fat, and rich in vitamins, minerals, and antioxidants

Carbohydrates are the primary fuel used during high-intensity exercise. They are also essential for replenishing glycogen stores in the muscles and liver after exercising. The current recommendation from the American College of Sports Medicine is for athletes to consume 5–10 grams of carbohydrates per kilogram body weight per day, depending on the exercise intensity and duration. While complex carbohydrates from whole foods are optimal for health, simple, high-glycemic-index carbohydrates can support athletic performance and glucose delivery during exercise.

A plant-based diet is also rich in vitamins, minerals, and antioxidants, which can improve recovery. Exercise produces free radicals, which can damage cells when their production exceeds the body's ability to neutralize them. Plant-based whole foods are high in antioxidants, which neutralize these free radicals. Plant-based diets have also been shown to reduce markers of inflammation in the blood.

In addition, a plant-based diet is low in fat. While fat is a necessary part of the diet, providing energy and supporting the absorption of fat-soluble vitamins, high-fat diets are not recommended for athletes due to their limitation of important nutrients, especially carbohydrates and fiber. Plant-based omega-3 fats found in nuts are anti-inflammatory and may promote recovery in athletes.

Overall, a plant-based diet provides all the nutrients needed for training and competition and can lead to improvements in heart health, performance, and recovery.

A plant-based diet can support or improve athletic performance

Athletes are increasingly adopting plant-based diets to support their training and improve performance. From tennis player Venus Williams to basketball player Kyrie Irving, many elite athletes are winning while eating plant-based. This has sparked interest among researchers, who are keen to understand the link between plant-based diets and athletic performance.

Weight loss and leaner bodies

Research shows that plant-based diets can help athletes lose weight and achieve leaner bodies. A clinical study by Barnard et al. found that a plant-based diet resulted in a statistically significant mean weight loss of 5.8 kg compared to a weight loss of 3.8 kg in the control group, who followed a meat-inclusive diet. Other studies have shown that plant-based diets are associated with lower body fat percentages and overall leaner bodies. This is desirable for improved athletic performance, as leaner bodies can improve strength and power while maintaining weight classes.

Improved stamina

Plant-based diets can also improve athletic stamina and endurance. Complex carbohydrates, which are abundant in plant-based diets, provide a longer-lasting and more stable supply of energy throughout the day. In addition, plant-based diets improve glycogen storage, which is essential for endurance training lasting more than 90 minutes.

Anti-inflammatory benefits

Plant-based diets are rich in antioxidants, B vitamins, and vitamin C, which can help counteract the inflammation caused by exercise. Dana Hunnes, PhD, MPH, RD, senior dietitian at the Ronald Reagan UCLA Medical Center, advocates for the anti-inflammatory benefits of plant-based diets. She states that a diet rich in fruits and vegetables can help reduce inflammation, leading to quicker recovery and enhanced muscle rejuvenation.

Cardiovascular benefits

Plant-based diets have also been linked to improved cardiovascular health, which is critical for endurance athletes. They can help reduce cardiovascular risk factors such as plasma lipid concentrations, blood pressure, and body weight. In addition, plant-based diets can improve blood flow and tissue oxygenation, which may enhance athletic performance.

Nutrient adequacy

One common concern about plant-based diets is whether they provide sufficient protein. However, this is a myth, as plant-based diets can provide enough protein for athletes. Foods such as lentils, beans, nuts, seeds, tofu, and quinoa are rich in protein and can meet the rigorous demands of athletes. In addition, plant-based diets tend to be high in vitamins, minerals, and fiber, while being low in saturated fat and cholesterol.

A plant-based diet can indeed support and improve athletic performance. It can help athletes achieve leaner bodies, improve stamina, reduce inflammation, and enhance cardiovascular health. With careful planning and a focus on nutrient-rich plants, athletes can meet their performance goals while fostering overall well-being.

A plant-based diet is associated with a lower body mass compared to vegetarian or omnivorous diets

Several studies have found that individuals following a vegetarian or vegan diet had a lower body mass index (BMI) compared to those following an omnivorous diet. One study found that vegans had the lowest average BMI, while non-vegetarians had the highest. Another study found that individuals following a vegetarian diet had a significantly lower body mass index than those following an omnivorous diet.

Furthermore, a plant-based diet can promote weight loss. One study found that individuals following a vegan diet lost significantly more weight than those following an omnivorous diet. Another study found that individuals following a plant-based diet lost an average of 11.5 kg, while those following a standard medical care diet lost only 1.6 kg.

Overall, a plant-based diet is associated with a lower body mass compared to vegetarian or omnivorous diets due to its lower calorie density, improved gut health, and favourable fat composition.

Plant-based diets are anti-inflammatory and can improve recovery

Inflammation is the body's natural response to injury or infection. It is the first step in the healing process, but when it becomes chronic, it can lead to several health issues. A plant-based diet can help reduce inflammation and improve recovery.

Inflammation is the body's natural defence mechanism against harmful stimuli, such as pathogens or injuries. It is characterised by redness, warmth, swelling, and pain. Acute inflammation is a quick and intense reaction that lasts for a few days. On the other hand, chronic inflammation is slow and lasts for months or years, causing damage to organs over time.

A diet high in refined, high-glycemic carbohydrates, trans fats, and omega-6 fatty acids can increase inflammation in the body. In contrast, a plant-based diet rich in fruits, vegetables, whole grains, and healthy fats can help reduce inflammation.

Plant-Based Diets and Inflammation

Plant-based diets are naturally anti-inflammatory as they are typically low in fat and free from animal products, which are high in fat and can trigger inflammation. Plant-based diets are also lower in toxins and bacterial load, reducing the risk of inflammation.

The Impact of Inflammation on Athletes

Inflammation can affect an athlete's performance and recovery. Chronic inflammation can lead to joint pain and fatigue, impacting an athlete's ability to train and perform at their best. A plant-based diet can help reduce inflammation and improve recovery, allowing athletes to train harder and perform better.

Sample Anti-Inflammatory Plant-Based Meals

• Blueberry Anti-Inflammatory Bowl: Quinoa flakes, unsweetened soy milk, vanilla extract, blueberries, and walnuts.
• Creamy Veggie & Hummus Pasta: Chickpea pasta, edamame, olive oil, cherry tomatoes, arugula, lemon juice, and hummus.
• Vegan Chopped Salad: Lentils, corn, red bell pepper, tomato, red onion, avocado, olive oil, lime juice, cilantro, and garlic.

Testimonials from Plant-Based Athletes

Several athletes have reported improved recovery and performance after switching to a plant-based diet:

• Ultrarunner Scott Jurek credits his plant-based diet for his success in endurance races, including setting a record for running the entire length of the Appalachian Trail in 46 days.
• American Olympic silver medallist Dotsie Bausch found that her recovery time decreased, and she could train more often and get stronger, faster.
• NBA veteran Chris Paul ditched animal products and noticed reduced inflammation and muscle pain, allowing him to stay active with his kids.
• Roma defender Chris Smalling adopted a plant-based diet to stay healthy and injury-free, and he found that his recovery time improved significantly.
• Arsenal defender Héctor Bellerín noticed improved recovery and less inflammation in his body after adopting a plant-based diet.

Plant-based diets can provide sufficient protein for athletes

The idea that a plant-based diet and being a strong, fit athlete are mutually exclusive is a myth. There are many world-class athletes who are vegan and have found that their performance has improved since making the switch.

Carbohydrates improve athletic performance

Carbohydrates should form the foundation of a vegan/vegetarian nutrition for athletes. Carbohydrates are vital for the functioning of muscles as well as nerve and brain cells. Complex carbohydrates are found mainly in fruits and vegetables as well as in wholegrain products (pasta, bread, oat flakes, muesli, couscous, brown rice, etc.), potatoes, and pulses. In addition, these foods contain a high proportion of dietary fibre, which prevents blood sugar levels from rising too quickly, thus ensuring stable performance.

Fats bolster energy reserves

Fats are a source of energy and play an important role in athletic success. The share of fats in one’s diet should constitute about 30-35% of overall calories. The German Nutrition Society, along with researchers in the field of nutritional science, states that fats should come primarily from plant-based sources.

Proteins for muscle development

Protein is used primarily to build and maintain body tissue, including muscles. Depending on the type of sport engaged in, a person’s protein requirements may increase.

The increased protein requirement can usually be met by food intake alone, so protein shakes and the like are generally not necessary.

Vitamins, minerals, and trace elements vital for sportspeople

Sportspeople on a vegan/vegetarian diet should keep an eye on critical nutrients such as calcium, zinc, vitamin B12, and iron. The latter is an essential part of the body’s oxygen delivery system, and is found in wholegrain cereals (oats, millet), legumes (lentils, white beans), nuts and seeds (sunflower seeds, pumpkin seeds), as well as vegetables (fennel, rocket, green peas, spinach, and so on).

A well-planned vegan diet really can help to increase and maximise athletic performance.
