Fruits often are overlooked as part of a nutritional plan for gaining strength and muscle. However, fruits contain important nutrients--and without the unwanted additives in processed food. According to the American Heart Association, you should eat at least eight servings of fruits and vegetables each day. The easy-to-digest sugars found in fruits can provide a quick burst of energy before your workout. Some fruits also contain proteins, the building blocks for muscle growth. So don't overlook these important components of a healthy diet.
Avocado
The avocado contains more protein than most fruit. One average-size avocado contains about 5 grams of protein. Freshly sliced or mashed avocado goes great on a sandwich. One serving size is a fifth of a medium avocado.
Blueberries
Blueberries contain a number of nutrients that are vital to overall health. In particular, they are high in manganese, which plays a role in the metabolism of proteins, fats and carbohydrates, and dietary fiber, which aids digestion. Sprinkle blueberries over your favorite cereal at breakfast. One serving size is half a cup.
Bananas
Bananas are a good source of manganese and potassium. Potassium is an important electrolyte that helps maintain proper blood pressure and heart function, which you should monitor if you work out daily. Bananas also have a reputation for helping to ease an upset stomach. Bananas also are a tasty addition to any smoothie. A serving size is one medium banana.
