18. Some Populations are at Higher Risk for Deficiency
Generally speaking, people in developed countries get plenty of protein in their diet. Protein deficiency is most common in developing countries, where widespread poverty leads to malnutrition (via Healthline). Some specific populations in the US and other developed countries are at particular risk for deficiency, most prominently older adults, especially those who live in nursing homes. People with cancer also tend to have difficulty eating as much protein as they need, and malnutrition in cancer patients can lead to more severe complications (via WebMD).
