Best High Protein Foods for Healthy Eating
Take a moment to appreciate that beautiful body of yours — that body that supports and guides you through life, fighting to keep you safe, giving you a place to call home. We wouldn’t have this body (or any body for that matter) without protein.
Protein is the foundation of our body. It constructs cells, muscles, enzymes, hormones, neurotransmitters, and immune antibodies. It also helps with growth and repair, keeping us healthy and strong. Just like building a house, we need the right materials to lay the foundations to structure our body.
Types of amino acids
High protein foods are composed of amino acids, the building blocks of life. There are 21 amino acids that arrange themselves in different combinations according to your body’s needs. Just like the building and upkeep of a house, you need the right amount of wood, cement, bricks, piping, plumbing, paint, etc., on hand whenever you need to make additions, changes, or repair your home.
Amino acids are classified as essential, conditionally essential, or nonessential. Consider these classifications as a general — not strict — guideline when designing or selecting a food plan. It’s difficult to know the specifics about each person’s daily amino acid usage and needs as it can depend on many different circumstances (stress, illness, growth, activity).
Nine of those 21 amino acids are essential amino acids, meaning that your body can’t produce them on its own and acquires them from high protein foods. They each serve a different purpose, benefiting everything from brain health and cell formation to detoxing.
Histidine: Used to produce neurotransmitters helpful for sexual, digestion, and sleep cycle functions.
Isoleucine: One of three branch-chain amino acids which help build muscle. It also supports the production of red blood cells and energy metabolism.
Leucine: Another one of the three branch-chain amino acids that enables building muscle. It also assists with wound healing and regulating blood sugar.
Valine: Last of the three branched-chain amino acids known to stimulate muscle growth and energy production.
Lysine: Enables hormone and enzyme production, aiding in the absorption of calcium. It increases energy, improves the immune function, and produces collagen.
Methionine: Needed for tissue growth and absorbing minerals (zinc and selenium). A key player in the detoxification process.
Phenylalanine: Helps produce neurotransmitters epinephrine and norepinephrine, responsible for fight or flight instincts.
Threonine: Supports skin and connective tissue health by producing collagen.
Tryptophan: A precursor to serotonin, the “happy” neurotransmitter that regulates appetite, sleep, and mood.
Conditionally essential amino acids
Considered to be non-essential conditionally essential amino acids may be required in more substantial amounts during certain circumstances such as illness, post-surgery, injury, or stress.
Arginine
Cysteine
Glutamine
Tyrosine
Nonessential amino acids
Required for normal health and growth, nonessential amino acids can be synthesized by the body.
Alanine
Asparagine
Aspartic acid
Glutamic acid
Proline
Serine
Pairing high protein foods
Foods with all of the essential amino acids mainly come from animal products (meat, eggs, poultry, dairy, fish). Soy (like the tofu in our Orange Tofu Stir-Fry photo below), quinoa, and buckwheat are a few of the plant-based variants that contain all of the essential amino acids. Other plant-based foods such as legumes, nuts, seeds, grains, and vegetables are considered to be incomplete as they lack one or more of the essential amino acids. However, you can remedy this by simply mixing and matching your foods.
These pairings of plant-based foods, eaten throughout the day will ensure you meet all of our amino acids needs. Mix and match the foods below while focusing on a consistent variety of high protein foods.
