Ask anyone who eats mostly plants which question they field most, and it’s this one. Where do you get your protein? It’s a fair question and it deserves an answer with research attached.
Plant Protein Is Harder For Your Body To Use
Animal and plant proteins differ in molecular structure, amino acid profile and digestibility, and those differences change how much of what you eat your body can actually use. Plant based foods generally deliver less complete protein because of lower digestibility and shortfalls in specific essential amino acids. That gap matters most for infants and young children because of their developmental needs, and less for adults.¹ For a healthy adult the difference is real, but it mostly means finding enough variety and enough total protein.
You Don’t Have To Pair Proteins At Every Meal
Older nutrition advice told vegetarians to combine foods at a single sitting, rice with beans or peanut butter with bread, so every meal delivered a full set of essential amino acids. That rule has loosened. What counts most is getting adequate essential amino acids throughout the whole day and paying attention to the amino acid profile of the proteins you choose.² Different plant foods run low in different essential amino acids,¹ so eating a range of them across the day is the practical approach. In older adults, 25 to 30 grams of protein per meal was enough to maximize muscle protein synthesis, and plant sources did that as effectively as animal ones.³ That research points toward spreading protein across the day instead of stacking it all at dinner. A plate built around lentils, beans or tofu at each meal does that without much planning.
Protein Needs Climb After Sixty Five
Older adults often fall short. In the U.S., roughly 30 percent of men and 50 percent of women over 71 don’t get enough protein, for reasons that include changes in gut function, appetite loss, tooth loss, cost and social isolation. The literature recommends roughly half a gram of protein per pound of body weight daily for healthy older adults, which comes to about 68 to 82 grams for someone weighing 150 pounds. The number climbs from there, to around two thirds of a gram per pound for those managing chronic or acute conditions and close to a full gram per pound in severe illness or malnutrition.³ A separate review of older adults with type 2 diabetes lands in the same place, about half a gram per pound daily spread evenly across meals, plus enough total calories to keep the body from breaking muscle protein down.⁴
Pregnancy Works With Supplements And Planning
Varied and well balanced vegetarian and vegan diets are considered safe and sufficient during pregnancy and lactation, as long as folate, vitamin B12 and vitamin D supplements are taken regularly and calcium, protein and iron intake stays adequate. Protein requirements may run higher for vegetarians and especially vegans, though the same guideline notes that the evidence behind that increase is limited.⁵ If you’re pregnant and eating plant based, this belongs in a conversation with your doctor or midwife early.
Meeting your protein needs on a plant based diet is doable. Lentils, beans, tofu, nuts and whole grains add up when you eat a range of them and pay attention to your daily total. So this week, look for the spots where your protein is thinnest and fill one with a source you don’t usually reach for. Taking care of the body God gave you is worth it, even in choices this small.
