Healthy strong muscles are important throughout the lifespan. Resistance training and sufficient dietary protein help support muscle maintenance and strength. Research has shown the importance of both the total amount of protein consumed each day as well as the amount of protein per meal. However, emerging research is showing other factors within food, besides protein, influence the synthesis of new proteins in muscle.
Over the past several years, scientists have examined how amino acids and isolated sources of protein impact muscle protein synthesis. This research serves as a foundation to better examine aspects beyond protein. Leucine, an essential amino acid, turns on the machinery driving the synthesis of new proteins in muscle. While leucine is the switch turning this process on, all essential amino acids are necessary to provide the building blocks for muscle protein synthesis to be running optimally. Quality sources of protein including whey, egg, soy and beef contain all essential amino acids in appreciable quantities to support this process. Yet studies comparing protein-rich drinks and whole foods have led to results that cannot be explained by differences in leucine or the amount of high quality protein consumed.

Eggs have a unique nutrition profile that is great for athletes of all ages. While they make a nice addition to any meal of the day, the nutrients in eggs can help with recovery after exercise. Just as stretching and cooling down is important after a workout, recovery nutrition is vital for repairing worn down muscle and revitalizing energy stores. But it’s not just the protein in eggs that make them a recovery food. Let’s take a look at the plethora of nutrients in eggs that help refuel a healthy athlete.
Protein: Research indicates that eating 20-30 grams of protein from foods that include leucine, such as eggs, may promote muscle repair after exercise1. One large egg contains 6 grams of high-quality protein with all nine essential amino acids. The International Society of Sports Nutrition recommends athletes focus on whole food sources of protein that contain all of the essential amino acids to aid in muscle protein synthesis2.
Vitamin D: This micronutrient is critical for bone health, and research suggests that adequate vitamin D intake reduces the risk of stress fracture, total body inflammation, illness, and impaired muscle function3. Unfortunately, adequate vitamin D intake is difficult to achieve due to variations in skin color, the time spent outdoors and geographic location. Eggs are one of the only natural food sources of vitamin D, with one large egg containing 6% of the daily value.
Lutein: This antioxidant has been known to accumulate in the eye, and scientists have recently discovered that it’s also present in the brain. Lutein in the eye may help athletes with visual performance and protecting the retina from damaging light4. Plus, new research in children suggests that lutein could have cognitive boosting capabilities and may even improve academic performance5. Luckily, lutein bioavailability is enhanced when it is consumed with dietary fat, making lutein from eggs a more absorbable source of lutein than many other foods6.
Other Benefits
Besides the impressive nutrient profile, eggs also have other practical applications for recovery, such as:

Optimal recovery protocols for athletes are critical to physical performance. Athletes and coaches often ask: What should an athlete eat after a workout? How much protein does an athlete need aft er a workout? What are easy and affordable options for post-workout recovery nutrition?
It’s no surprise that your normal fitness routine can take a hit while traveling for the holidays. But the following FIVE tips include some surprisingly simple ways to get your sweat on even in the face of a demanding holiday travel schedule.
In nutrition science, individual nutrients are often recognized for their specific roles in physiology. We know that calcium is critical for bone health, choline is important for brain development and a lack of vitamin C will result in scurvy. However, whole foods are complex and contain numerous compounds, often leading to effects that extend beyond the sum of their parts.
