Chemists first recognized the importance of protein in 1838. Since then, the macronutrient has been in and out of the spotlight countless times as diet trends and exercise fads come and go.
What hasn’t changed is that protein remains one of our three primary sources of calories, along with carbohydrates and fats.
And while protein is currently getting a lot of attention thanks to its role in the latest high fat, low carb craze, we’ve always been a fan because of its long list of benefits.
About 20% of the human body is made up of proteins—large, complex molecules that play an important role in your body.
Weight Loss and Maintenance
Protein is the single most important nutrient for weight loss. Along with fat, it’s digested slower than carbohydrates, making you feel fuller for longer. That appetite suppressing benefit can make it easier to eat fewer calories in a day, without feeling hungry. Eating *enough protein-rich food also boosts your metabolism and improves your weight-regulating hormones. And protein helps prevent muscle loss when you’re working hard to reduce your body fat.
Your Cells Depend on It
Protein is an important part of every cell in your body. It’s used to build and repair tissues, and to make enzymes, hormones, and other body chemicals. It’s also an important building block of skin, bones, muscles, cartilage, and blood.
Bolster Your Immune System
Antibodies are proteins in your blood that help protect you from infections. They’re crucial for fighting disease. Without them, bacteria and viruses would be free to grow and invade your body. When your antibodies are in check, your body works harder to develop immunity against diseases it’s exposed to.
Reduce the Wrinkle Factor
Collagen is the most abundant protein in your body and is the structural protein of your bones, tendons, ligaments, and skin. It works to reduce the appearance of wrinkles, lines, and indentations because it helps your skin retain its elasticity.
Best High Protein Food Sources
Your body doesn’t store protein, which is why it’s important to get enough from your daily diet. And the sources are plentiful, from lean meats to nuts, seeds, eggs, and dairy products. One cup of Ocean’s sustainably caught tuna packs a whopping 39 grams of protein per cup. Try it in our Tuna Grain Bowl for an easy-to-make, high protein dinner or lunch option.
*Everybody’s body is different, and your protein requirements will vary from those of others. While you can calculate average consumption needs based on body weight and fitness goals, we recommend consulting your doctor before making any dietary changes.
