Iron deficiency is the most common nutritional deficiency worldwide and is one of the main factors contributing to the global burden of disease. Iron deficiency can also lead to anemia, a blood condition that causes fatigue, weakness, dizziness, and a low level of immune support. Iron deficiency is one of the most common nutrient deficiencies in the world, affecting more than 25% of people worldwide (1,. About 30% of menstruating women may also have a deficiency due to monthly blood loss, and up to 42% of young pregnant women may also have a deficiency.
In addition, vegetarians and vegans are at greater risk of deficiency because they only consume non-heme iron, which is not absorbed as well as heme iron (3,. Symptoms often include tiredness, weakness, weakening of the immune system, and impaired brain function (5,. Iron deficiency is very common, especially among young women, children and vegetarians. May cause anemia, fatigue, weakening of the immune system and deterioration of brain function.
The most common symptom of iodine deficiency is an enlarged thyroid gland, also known as a goiter. It can also cause an increase in heart rate, shortness of breath, and weight gain (. Severe iodine deficiency is linked to serious harm, especially in children. It can cause mental retardation and developmental abnormalities (8,.
Some countries require the enrichment of table salt with iodine, which has successfully reduced the incidence of deficiencies (1). Iodine is one of the most common nutrient deficiencies in the world.). May cause thyroid gland enlargement. Severe iodine deficiency can cause mental retardation and developmental abnormalities in children.
Vitamin D is produced from cholesterol in the skin when exposed to sunlight. Therefore, people who live far from the equator are likely to have a deficiency, unless their dietary intake is adequate or they supplement with vitamin D (13, 1). In the United States, about 42% of people may be deficient in this vitamin. This figure rises to 74% in older adults and 82% in people with dark skin, since their skin produces less vitamin D in response to sunlight (15, 1) Vitamin D deficiency is not usually evident, since its symptoms are subtle and can develop over years or decades (17, 1).
Adults with vitamin D deficiency may experience muscle weakness, bone loss, and an increased risk of fractures. In children, it can cause growth delays and soft bones (rickets) (17, 20, 2). In addition, vitamin D deficiency may contribute to reduced immune function and increase the risk of cancer (2). Vitamin B12, also known as cobalamin, is a water-soluble vitamin.
Every cell in the body needs vitamin B12 to function normally, but the body can't produce it. Therefore, you should get it from food or supplements. Vitamin B12 is only found in sufficient amounts in animal foods, although certain types of seaweed may provide small amounts. Therefore, people who do not eat animal products are at greater risk of deficiency.
More than 20% of older adults may also be deficient in this vitamin, as absorption decreases with age (26, 27, 2). A common symptom of vitamin B12 deficiency is megaloblastic anemia, which is a blood disorder that increases the size of red blood cells. Other symptoms include impaired brain function and high levels of homocysteine, which is a risk factor for several diseases (29, 30). Vitamin B12 deficiency is very common, especially in vegetarians, vegans and older adults.
The most common symptoms include blood disorders, impaired brain function, and high homocysteine levels. A survey conducted in the United States revealed that less than 15% of adolescent girls, less than 10% of women over 50, and less than 22% of adolescents and men over 50 years of age met the recommended calcium intake (3). Symptoms of more severe dietary calcium deficiency include soft bones (rickets) in children and osteoporosis, especially in older adults (32, 35). 3.Vitamin A is an essential fat-soluble vitamin.
Helps form and maintain healthy skin, teeth, bones, and cell membranes. In addition, it produces eye pigments, which are necessary for vision (3). More than 75% of people who follow a Western diet get more than enough vitamin A and don't have to worry about its deficiency (3). Vitamin A deficiency can also suppress immune function and increase mortality, especially among children and women who are pregnant or breastfeeding (40).
About 70% of the U.S. population under 71 and approximately 80% over 71 years of age consume less than the required amount of magnesium. Low magnesium intake and blood levels are associated with several conditions, such as type 2 diabetes, metabolic syndrome, heart disease, and osteoporosis (4). Deficiency may be due to illness, drug use, reduced digestive function, or inadequate magnesium intake).
The main symptoms of severe magnesium deficiency include an abnormal heart rhythm, muscle cramps, restless legs syndrome, fatigue, and migraines (49, 50, 5). Nutrient deficiencies can also lead to illness. Calcium is important for keeping bones strong and controlling muscle and nerve function, according to the National Institutes of Health (NIH). Signs of a very low calcium level include numbness, tingling in the fingers and abnormal heart rhythms, according to the Cleveland Clinic.
That said, there are no obvious, short-term symptoms of calcium deficiency. Most adults need 1,000 milligrams (mg) of calcium per day, although women over 50 and men over 70 need 1200 mg, according to the Mayo Clinic. Patton says you're likely to get enough with at least three servings of milk or yogurt a day. Cheese is another good source of calcium, but if you don't like dairy, you can find this nutrient in calcium-fortified orange juice or breakfast cereals (check the food's nutrition label to see if calcium has been added) and in dark leafy vegetables such as kale and broccoli, according to the NIH.
This vitamin is another one that is crucial for bone health and may also prevent some types of cancer, according to the Cleveland Clinic. Symptoms of vitamin D deficiency can include vague fatigue, bone pain, mood swings, and the onset of muscle aches or weakness. According to the Mayo Clinic, you could have low potassium levels in the short term due to diarrhea or vomiting, excessive sweating, antibiotics, laxatives or diuretics, excessive alcohol consumption, or because of a chronic condition, such as kidney disease. Symptoms of a deficiency include muscle weakness, contractions or cramps; constipation; tingling and numbness; and abnormal heart rate or palpitations, according to MedlinePlus.
For natural sources of potassium, try bananas, milk, acorn squash, lentils and red beans, and other legumes. Adult men need 3,400 mg per day and women need 2,600 mg, according to the NIH. To increase iron levels, Patton recommends eating iron-fortified cereals, beef, oysters, beans (especially lima, white beans, and red beans), lentils, and spinach. Adult men and women over 50 need 8 mg per day, and adult women under 50 need 18 mg a day, according to the NIH.
Vitamin B12 helps the production of red blood cells and DNA, and also improves neurotransmitter function, according to the NIH. Vegetarians and vegans may be at special risk of suffering from vitamin B12 deficiency because plants don't produce the nutrient, and people who have undergone weight-loss surgery may also lack vitamin B12 because the procedure makes it difficult for the body to extract the nutrient from food, according to Harvard Health Publishing. Symptoms of severe B12 deficiency include numbness in the legs, hands, or feet; problems walking and maintaining balance; anemia; fatigue; weakness; a swollen and swollen tongue; memory loss and difficulty thinking, according to Harvard Health Publishing. These symptoms can appear quickly or gradually, and because there is such a wide variety of symptoms, you may not notice them for a while.
Magnesium helps maintain bone health and helps energy production, and adults need between 310 and 420 mg, depending on gender and age, according to the NIH. While deficiency is fairly rare in otherwise healthy people, certain medications (including some antibiotics and diuretics) and health problems (such as type 2 diabetes and Crohn's disease) can limit magnesium absorption or increase the loss of this nutrient from the body.
