Step-by-step explanation:
A sign of poor nutrition is hair that is stringy, dull, brittle, dry, friable, and depigmented. This is because the body may not be getting enough nutrients, such as protein and vitamins, to support healthy hair growth and maintenance. Other signs of poor nutrition include loss of appetite, poor growth, weight loss, skin problems, hair loss, vision problems, and lack of taste or smell.
In severe cases of malnutrition, individuals may experience symptoms like dry and scaly skin, slow wound healing, easy bruising, compromised immunity, and diseases like scurvy. These symptoms are a result of nutrient deficiencies and a weakened body.
Overall, a proper diet that includes a variety of nutritious foods is important for maintaining good overall health and preventing the signs of poor nutrition.
