The Health Benefits of Protein
Protein is one of the most important nutrients in your diet. It builds and repairs pretty much everything in your body, from muscles to skin to hormones.
Research backs this up. A review of 65 clinical trials (nearly 3,000 people) found that getting enough protein helped people build and keep lean body mass, whether they were young or older adults. A large study following over 416,000 people also found that choosing more plant protein over animal protein was linked to a lower risk of dying from any cause, including cardiovascular disease. Beyond muscle, protein plays a role in a healthy immune system, brain development in babies, and countless other body functions.
Key takeaway: Protein isn't just for athletes. Everyone needs it for basic body maintenance and long-term health.
How Much Protein Do You Actually Need?
The standard recommendation (RDA) is 0.8 grams per kilogram of body weight per day. This includes a built-in safety cushion above the bare minimum your body needs.
Newer 2025 to 2030 Dietary Guidelines suggest aiming higher, around 1.2 to 1.6 grams per kilogram per day (about 16 to 21% of your daily calories), a target that is not universally endorsed by nutrition experts. That said, this higher amount seems to help most when it's paired with regular strength training. Without that, the extra benefit isn't as clear.
Don't go too low or too high. Dropping below 0.4 to 0.5 grams per kilogram can lead to muscle loss, while eating more than 2 grams per kilogram for a long time may cause problems.
For most people over age 3, protein should make up 10 to 35% of total daily calories.
Best Protein Choices for Your Heart
Both the American Heart Association (2026) and the American College of Cardiology (2025) recommend leaning toward more plant-based proteins for heart health.
Beans, peas, and lentils: Packed with protein, fiber, and healthy fats. Diets higher in these and lower in red or processed meat are linked to lower heart disease risk.
Nuts and seeds: Eating more nuts is linked to a lower risk of heart disease and early death.
Fish and seafood: The omega-3 fats in fish help protect your heart rhythm and lower cardiovascular death risk.
Poultry: A solid swap for red meat, though it doesn't offer quite the same heart benefits as plant proteins or fish.
Low-fat dairy: The research here is mixed, but some studies link dairy protein to lower cardiovascular death rates.
Processed meats like bacon, sausage, hot dogs, and deli meats are best kept to a minimum. They're consistently linked to higher risk of heart disease, cancer, and diabetes.
Worth noting: One large study found that eating just 2 extra servings of processed meat per week was linked to a 1.74% 30-year absolute risk difference of heart disease. Unprocessed red meat showed a smaller, but still real, increase (0.62%).
Where to Find Protein?
Animal sources like milk, beef, eggs, poultry, and fish contain all 9 essential amino acids your body needs, and they're easy for your body to absorb.
Plant sources are great too. Soy is the highest-quality plant protein, followed by beans and legumes, whole grains, nuts, and seeds.
If you're vegetarian or vegan, you can absolutely get enough protein by eating a variety of plant foods. Just keep an eye on vitamin B12, vitamin D, calcium, iron, zinc, and iodine, since these can be harder to get without animal products.
Who Should Be Careful With High-Protein Diets?
While protein is important for most people, eating a lot of it isn't the right approach for everyone. Here's what you need to know:
Chronic Kidney Disease (CKD): This is the group that needs to be most careful. If you have kidney disease, too much protein can put extra strain on your kidneys and speed up damage. Your doctor or dietitian will likely recommend limiting protein.
Inherited Metabolic Conditions (such as Phenylketonuria): People born with phenylketonuria (PKU) must strictly limit high-protein foods like meat, fish, cheese, and eggs because their bodies cannot properly break down an amino acid called phenylalanine. They need lifelong dietary management with special amino acid supplements.
Gout and High Uric Acid: If you have gout, the issue isn't protein itself, it's the type of protein you eat. Red meat, organ meats, and shellfish can raise uric acid levels and trigger flare-ups. However, plant-based proteins (beans, nuts, seeds), dairy, and eggs may actually be protective. So rather than cutting protein overall, focus on choosing the right sources. Healthy eating patterns like the Mediterranean or DASH diets are now recommended over the old-fashioned blanket low-protein approach.
Bottom line: If you have any of these conditions, talk to your doctor or a registered dietitian about the right amount and type of protein for you.
Not Sure How Much Protein Is Right for You?
Everyone's protein needs are different, depending on your age, activity level, health history, and goals. Guessing can leave you eating too little or too much, and if you have a health condition like kidney disease, getting it wrong can actually cause harm.

How Much Protein Do You Really Need? A Dietitian's Guide (Cedar Park, TX)
Protein plays a huge role in keeping your body strong, from building muscle to supporting your immune system. But how much you need, and whether more is always better, depends a lot on your individual health. Most healthy adults benefit from meeting or slightly exceeding the standard recommendations, especially when paired with regular exercise. However, high protein intake isn't right for everyone. People with chronic kidney disease, certain liver conditions, some metabolic disorders, and specific inherited health conditions need to approach protein very differently, since too much can actually do more harm than good. This guide breaks down how much protein you really need, the best heart-healthy sources to reach for, and who should talk to a professional before upping their intake. If you're in the Cedar Park or greater Austin area and want a plan built around your health, not a generic chart, Hita Nutrition is here to help.
