How To Get Enough Protein On A Bone-Healthy Diet

In recent years, protein has become a major focus in nutrition and healthy-aging discussions, leading many people to reevaluate their intake of this essential macronutrient. At the Save Institute, protein has always been central to a bone-healthy diet, but our approach also includes an important factor often overlooked by the Medical Establishment: pH balance.

Traditional high-protein diets often rely on acid-forming foods that can contribute to bone mineral loss and increase osteoporosis and fracture risk.

In this article, you will learn how to strategically combine alkalizing, plant-based protein sources to maximize muscle growth and protect bones without disrupting pH balance.

Complete Proteins Contain These Nine Amino Acids

Protein is a macronutrient composed of amino acid building blocks. Twenty amino acids combine to create every protein in the human body. The body can produce eleven of those amino acids on its own. The remaining nine are called “essential amino acids” because they must be obtained through the diet.

The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Foods that contain all nine are considered “complete proteins.”

However, the idea of a complete vs an incomplete protein is a bit misleading. All plant foods contain all 20 dietary amino acids, just not in equal measure. “Complete” proteins contain a balance of the nine essential amino acids that mirrors human dietary requirements.¹

Foods considered incomplete proteins have a “limiting amino acid.” If an incomplete protein were the only food you ate, you would have to eat much more of it to get enough of the limiting amino acid to meet your daily protein requirement.

Lysine and methionine are the two amino acids most likely to be limiting. Grains tend to have a low lysine content, and beans tend to be lacking in methionine.

Eating foods with different limiting amino acids within a 24-hour window– for example, eating grains and beans– creates complementary proteins.¹ This occurs naturally through eating a varied diet, and it’s why vegans are able to get all of the protein they need from a totally plant-based diet.

Studies have found that the difference in amino acid balance between a mostly plant-based diet and a more animal-based diet is negligible for most people.¹

Synopsis

There are nine essential amino acids that you can only get from your diet. Sources of complete protein offer all nine in adequate levels, while incomplete proteins have a “limiting” amino acid. Eating foods with different limiting amino acids constructs complementary proteins.

Constructing A Protein-Rich Diet That Won’t Hurt Your Bones

Strategically combined alkalizing plant proteins can provide all the essential amino acids in their ideal ratios to effectively support muscle and bone health. As the studies above demonstrate, this doesn’t require a complicated dietary plan– simply eating a variety of protein-rich plant foods is usually sufficient.

Try some of these high-protein plant food combinations. These complementary plant proteins result in meals with a balanced amino acid profile of a “complete” protein, without causing bone-damaging acidification.

• A lentil and quinoa lunch bowl with your toppings of choice
• Bean salad with hot polenta cakes
• Hummus with whole-grain pita
• Amaranth tabboule with chickpeas
• A breakfast smoothie with organic soy milk, oats, and chia seeds
• Kasha with green peas and lentils
• Split pea soup topped with toasted buckwheat groats
• Lentil soup with whole-grain toast points
• Rice with black beans
• White Beans on whole-grain toast

These combinations provide complete proteins from plant sources, but that doesn’t mean you must avoid protein from animal products. The Save Institute’s Osteoporosis Reversal Program doesn’t exclude animal protein. Savers can eat beef, chicken, eggs, fish, and some dairy, provided they balance those acidifying proteins with alkalizing foods such as vegetables, greens, herbs, and fruits to maintain a bone-healthy pH balance.

Synopsis

Try the combinations of plant-protein sources above to ensure you get the right balance of essential amino acids in your diet. Plant foods can meet your protein needs while helping you maintain a pH-balanced diet. The Osteoporosis Reversal Program doesn’t exclude animal protein; in moderation, animal products can be a part of your bone-building diet.

Protein For Your Bones

Your bones are composed principally of minerals and collagen— not protein. However, adequate protein intake is critical for bone health, primarily because it builds and maintains muscle mass.

Eating protein-rich foods isn’t enough, though; maintaining and growing muscle mass requires exercise. Exercise causes tiny tears in muscle tissue, which the body repairs by building additional tissue, increasing muscle mass.

This is why exercise makes you stronger. Protein provides material for the process, but if you don’t do the exercise, you won’t get all of the benefits protein has to offer.

The timing of your protein intake can also impact muscle growth. A study published in the American Journal of Clinical Nutrition found that older adults who evenly distributed their daily protein intake across meals had greater muscle strength. You can apply that finding by spreading out your protein intake across the day. Instead of protein-loading at breakfast or after your workout, try to eat part of your daily protein at each meal. ²

The updated 2026 food guidelines recommend an increased protein intake of 1.2 to 1.6 grams per kilogram of body weight per day for all adults, up from the previous minimum of 0.8 grams per kilogram. For older adults, especially, getting adequate protein (and adequate exercise!) is essential to avoid muscle loss and protect bone health.

Synopsis

Dietary protein won’t help you build muscle strength unless you exercise. A study of older adults found that spreading out protein intake across the day was associated with greater muscle strength. Getting adequate protein and exercise is essential to avoid muscle loss and protect bone health.

What This Means To You

An alkalizing diet can easily meet your protein needs. Eat a variety of protein-rich plant foods and animal protein balanced with plenty of alkalizing foods throughout the day to support the health of your bones and the strength of your muscles. And remember that protein and exercise work together to build and maintain strong muscles and bones.

The Save Institute created SaveTrainer to make it easy to accomplish the exercise your body needs to keep your muscles and bones healthy and strong.
