Protein is a nutritional powerhouse. Absolutely. It helps build muscle, repair tissues,
keep you full, and support your immune system. No wonder it’s the center of so many
diets! But here’s the truth: while getting enough protein is important, getting too much
can actually cause more harm than good.
The average adult needs about 0.8 grams of protein per kilogram of body weight. Yes,
this is a generalization. Athletes and active people will need more, sure — but chugging
protein shakes and doubling up on meat at every meal can easily push you into excess
territory. And over time, that can put unnecessary strain on your kidneys, especially if
you already have any kidney concerns. High protein intake can also lead to dehydration,
calcium loss, and possibly kidney stones.
The other unintended consequence of excess protein consumption is that when protein
takes over your plate, other important foods — like fiber-packed fruits, veggies, and
whole grains — can get left out. This means you might miss out on essential nutrients
that keep your heart healthy, your digestion smooth, and your body and mind running at
its best. And if your high-protein meal plan is heavy on red or processed meats, your
long-term heart health could take a hit, too.
Bottom line: protein is important, but, as with everything, moderation matters. You can
absolutely meet your needs through food without going overboard. Aim for variety,
balance, and quality sources.
