A new consumer guide and recent science reviews clarify eight common myths about dietary protein.
The findings show who needs more protein, how timing matters less than once thought, and why most healthy people need not fear their kidneys (Tasting Table guide).
The debate about protein confuses many readers.
Nutrition messages have swung wildly for decades.
Experts still use the RDA of 0.8 grams per kilogram of body weight.
This level prevents deficiency in sedentary adults (Harvard Health).
Newer studies suggest many adults may benefit from more protein than the RDA.
Research finds benefits for muscle, strength, and body composition at higher intakes (Revised Reference Values review).
Protein supports many daily functions in the body.
It helps hormones, digestion, blood clotting, and cell repair (Tasting Table guide).
The body contains thousands of different proteins.
Most of the body’s protein mass sits in skeletal muscle (Tasting Table guide).
Strength training builds muscle, not protein alone.
You need both resistance exercise and adequate protein to grow muscle (Tasting Table guide).
Protein alone will not make a person very muscular.
Exercise stimulates muscle growth and protein supports recovery.
For many adults the best protein range lies between 0.9 and 1.6 g/kg.
Intakes above about 2.0 g/kg show no additional benefit and may risk harm (Revised Reference Values review).
Slight increases above 0.8 g/kg help maintain muscle.
Some studies show benefits from moving to about 1.0–1.2 g/kg for active adults (Personalized dietary advice trial).
Higher-protein diets can support weight loss.
They improve satiety and protect lean muscle during calorie reduction (systematic review).
Excess protein calories convert to fat.
The body cannot store unused amino acids as muscle.
The so-called “anabolic window” after exercise is longer than once thought.
Researchers now say the effective window may stretch for hours, not minutes (Nutrient timing review).
Pre-exercise meals reduce urgency for a post-workout protein dose.
If you ate protein before training, you have more time after exercise.
If you train fasted, you should eat protein sooner after exercise.

Clinic nutritionists should assess protein needs by age and activity.
They must tailor advice for body weight, health status, and goals.
Primary care providers should screen kidney patients before suggesting high protein.
Doctors must personalise protein targets for chronic disease patients (Mayo Clinic guidance).
Nutrition education should teach practical protein portions.
Examples help readers translate grams into common Thai foods.
A 75 kg adult needs about 60 grams at 0.8 g/kg.
At 1.0 g/kg they need 75 grams, an easy shift with small food swaps (Tasting Table guide).
Two ounces of cooked chicken provides about 15 grams of protein.
Five ounces of Greek yogurt can also give about 15 grams.
Older adults should aim for protein at each meal.
Distributing intake across the day supports muscle protein synthesis (protein distribution research).
