Signs You're Not Getting Enough Protein

Signs You're Not Getting Enough Protein

Swelling

One of the most common signs that you're not getting enough protein is swelling (also called edema), especially in your abdomen, legs, feet, and hands. A possible explanation: The proteins that circulate in your blood -- albumin, in particular -- help keep fluid from building up in your tissues. But many things can cause edema, so be sure to check with your doctor in case it's more serious.

Mood Changes

Your brain uses chemicals called neurotransmitters to relay information between cells. Many of these neurotransmitters are made of amino acids, which are the building blocks of protein. So a lack of protein in your diet could mean your body can't make enough of those neurotransmitters, and that would change how your brain works. With low levels of dopamine and serotonin, for example, you may feel depressed or overly aggressive.

Hair, Nail, and Skin Problems

These are made up of proteins like elastin, collagen, and keratin. When your body can't make them, you could have brittle or thinning hair, dry and flaky skin, and deep ridges on your fingernails. Your diet isn't the only possible cause, of course, but it's something to consider.

Weakness and Fatigue

Research shows that just a week of not eating enough protein can affect the muscles responsible for your posture and movement, especially if you're 55 or older. And over time, a lack of protein can make you lose muscle mass, which in turn cuts your strength, makes it harder to keep your balance, and slows your metabolism. It can also lead to anemia, when your cells don't get enough oxygen, which makes you tired.

Hunger

This one might seem obvious. Protein fuels you. It's one of three sources of calories, along with carbs and fats. If you want to eat a lot of the time even though you have regular meals, you may need more protein. Studies have found that eating foods with protein helps you feel fuller throughout the day.

Slow-Healing Injuries

People who are low on protein often find their cuts and scrapes take longer to get better. The same seems to be true of sprains and other exercise-related mishaps. It could be another effect of your body not making enough collagen. It's found in connective tissues as well as your skin. To make blood clot, you need proteins, too.

Getting or Staying Sick

Amino acids in your blood help your immune system make antibodies that activate white blood cells to fight off viruses, bacteria, and toxins. You need protein to digest and absorb other nutrients that keep you healthy. There's also evidence that protein can change the levels of disease-fighting "good" bacteria in your gut.

Who Might Come Up Short?

Most Americans get plenty of protein. People who don't get enough usually have an overall poor diet. Elderly people and people with cancer may have trouble eating as much protein as they need. Severe malnutrition from lack of protein is called kwashiorkor. It's more common in developing countries, especially with children, or after a natural disaster.
