Can lack of protein in a diet cause side effects or harm to overall health?

Question

What kind of signs should I look for in my body?

Answer 1

Symptoms of protein deficiency
The human body can’t store protein, so it must be supplied on a daily basis from the foods we eat. Strict vegetarians who don’t consume any animal products at all are at increased risk of protein deficiency if they don’t eat a wide range of complementary plant proteins. Symptoms of protein deficiency include:
Wasting and shrinkage of muscle tissue
Oedema (build-up of fluids, particularly in the feet and ankles)
Anaemia (the blood’s inability to deliver sufficient oxygen to the cells, usually caused by dietary deficiencies such as lack of iron)
Slow growth (in children).
