3. Lowered Immune Functioning
A low protein level may also make susceptible to diseases and sickness.
Since the immune cells are mostly made from proteins, they help keep your immune system functioning properly.
Proteins make up white blood cells (WBC), antibodies, blood proteins and a host of immune molecules, including cytokines and interleukins.
All these molecules work together to combat invading foreign particles, both biological and chemical.
So, if you don’t eat sufficient protein, it can compromise your body’s ability to produce enough immune molecules and weaken your immunity.
This is often seen in frequent and severe infections or illness.
4. Poor Hair Health
Your hair is made mostly of a protein known as keratin, and this makes protein essential for hair health.
Protein is the building block of all cells and tissues; in fact, your hair follicle is made up of protein. Each and every of your hair strand requires an adequate dose of protein to grow.
So, when your body does not have sufficient protein, it starts conserving the little one and thus limiting protein output. The resulting effect is uncontrolled hair loss.
Apart from that, your hair also becomes dry and brittle.
5. Weak and Brittle Nails
Weak and brittle nails are one of the first common signs of lack of proteins.
Just like the hair, nails are also made up of keratins protein. So, to have a strong and healthy nail, you need to up your protein intake.
When your body doesn’t have sufficient protein, it does not have enough protein to grow strong nails. In addition, inadequate protein intake can cause white spots on your nails.
Furthermore, the lack of protein may lead to more frequent hangnails as well as cracks and tears in the nails. This can make your nails susceptible to infections such as nail fungus.
