Main sources of protein
Protein is an essential macronutrient that plays a vital role in many bodily functions. It is the building block of muscles, bones, skin, hair, and nails. Protein is also needed to produce hormones and enzymes, which regulate various bodily processes.
Here are some of the main sources of protein:
- Animal sources: Meat, poultry, fish, eggs, dairy products
- Plant-based sources: Legumes, beans, nuts, seeds, whole grains, tofu, tempeh
Animal sources of protein
Animal sources of protein are generally considered to be complete proteins, meaning that they contain all nine essential amino acids that the body cannot produce on its own. Essential amino acids are needed for building and repairing muscle tissue.
Some good examples of animal sources of protein include:
- Meat: Chicken, beef, lamb
- Poultry: Chicken, turkey, duck
- Fish: Salmon, tuna, mackerel, sardines
- Eggs: Whole eggs, egg whites
- Dairy products: Milk, yogurt, cheese
Plant-based sources of protein
Plant-based sources of protein are not generally considered to be complete proteins, but they can still be good sources of protein. However, it is important to eat a variety of plant-based protein sources throughout the day to ensure that you are getting all nine essential amino acids.
Some good examples of plant-based sources of protein include:
- Legumes: Beans, lentils, peas
- Nuts: Almonds, walnuts, cashews, peanuts
- Seeds: Chia seeds, pumpkin seeds, sunflower seeds
- Whole grains: Quinoa, oats, brown rice
- Tofu and tempeh
How much protein do you need?
The recommended daily intake of protein for adults is 0.8 grams per kilogram of body weight. However, some people may need more protein, such as athletes, pregnant women, and breastfeeding mothers.
Tips for getting enough protein
Here are a few tips for getting enough protein:
- Include a source of protein at every meal.
- Choose lean protein sources, such as chicken, fish, and beans.
- Snack on nuts, seeds, or hard-boiled eggs.
- Add protein powder to smoothies or yogurt.
If you are struggling to get enough protein from food alone, you may want to consider taking a protein supplement. However, it is important to talk to your doctor before taking any supplements.
