How Much Protein Is Too Much for Daily Health
Protein helps your muscles, skin, hair, nails, immune system, and bones.
Your body needs a certain amount each day, but more is not always better.
Most healthy adults with little physical activity need about 0.8 grams per kilogram of body weight.
People who exercise may need more protein.
Eating too much protein can make some people thirsty or dehydrated.
It may also cause bad breath, stomach problems, tiredness, or weight gain.
Focusing only on protein can mean missing carbohydrates, fats, fiber, and other nutrients.
Eating different kinds of foods and asking a health professional about supplements can help keep your diet balanced.
Healthy adults with minimal activity generally need 0.8 grams of protein per kilogram of body weight daily.
Moderate exercisers may need 1.0 to 1.3 grams per kilogram, while intense athletes may need 1.6 to 2.0 grams.
Excessive protein intake may contribute to dehydration, digestive problems, bad breath, and unintended weight gain.
Very high-protein diets can reduce intake of carbohydrates, fats, fiber, and other essential nutrients.
A balanced diet and professional advice about supplements can help people meet protein needs safely.
