When life is fast-paced, many people will have hasty meals to continue with work and study. Because they do not have time to pay attention to the nutritional issues in their meals, it is easy to lead to malnutrition, according to the health website Healthline (USA).

Symptoms that may be warning signs of vitamin deficiency include:

Mouth ulcers

Mouth ulcers or cracks at the corners of the lips can be caused by a lack of vitamin B2. This vitamin is essential for cell function. Deficiencies of iron and other B vitamins can also cause similar symptoms. To get these vitamins, people should eat meat, fish, cereals, and drink milk.

Bleeding gums

Poor oral hygiene is a common cause of bleeding gums. Vitamin C deficiency can also lead to this symptom. Vitamin C is essential for collagen synthesis and maintaining gum health.

Along with bleeding gums, vitamin C deficiency can also lead to easy bruising, dry skin, and slow wound healing. Foods rich in vitamin C include broccoli, strawberries, bell peppers, and citrus fruits.

Hair loss

Hair loss can be a worrying sign of iron, zinc, linoleic acid or vitamin B3 deficiency. Iron deficiency is also a common cause of hemoglobin deficiency, a protein that helps blood transport oxygen throughout the body, including hair follicles.

Hair follicles that do not receive enough oxygen will weaken and cause hair loss. To supplement iron, people should eat iron-rich foods such as red meat, spinach, lentils and some other beans.

Reduced vision

Poor vision and poor night vision can be signs of vitamin A deficiency. This vitamin plays an important role in vision, helps maintain immunity and skin health. To prevent vitamin A deficiency, we can eat foods rich in this vitamin such as carrots, sweet potatoes and apricots.

Restless legs syndrome

Restless legs syndrome is characterized by an uncomfortable feeling and urge to move your legs. The condition is linked to low levels of magnesium and iron in your blood. Supplementing with these two minerals may help relieve symptoms. Foods rich in magnesium include whole grains, nuts, and seeds, according to Healthline .
