BEETS
Beets are a good source of betaine, also known as trimethylglycine. This nutrient not only enhances liver and joint repair, but also has been shown in clinical research to increase muscle strength and power. Beets have recently been found to increase the diameter of blood vessels by boosting nitric oxide (NO) levels. That’s because beets provide a rich source of nitrates. Nitrates are nitrogen-containing compounds that contribute to the production of NO. Nitrate in beets is converted by bacteria living on the tongue into the chemical nitrite. After nitrite is digested it becomes NO. This molecule relaxes the muscles in blood vessels, widening them, which allows more blood to flow through them. This greater blood flow means that muscles get more blood along with more nutrients like amino acids and glucose, as well as oxygen, which can enhance energy and aid recovery.
Recommendation:
Try adding some beetroot juice to your preworkout protein shakes. Each cup provides about 100 calories, 24 g of carbs, 2 grams of protein and no fat.
