When talking about a healthy diet, most of us tend to focus mainly on the ratio between carbohydrates, fats and proteins, but as you probably know, a truly high-quality menu is based on dozens of much smaller components, without which the body simply does not function properly. A deficiency in them is not always felt immediately, but when it does manifest, it does so in surprising and sometimes misleading ways.
Vitamins and minerals are required in relatively small quantities, but they are involved in almost every biological process – from blood clotting to normal vision, from bone health to energy production. Health organizations emphasize again and again that a balanced diet is supposed to provide daily needs without the need for supplements, but in practice quite a few people suffer from subclinical deficiencies that are not immediately diagnosed because they do not cause obvious damage, yet may negatively affect health in the long term.
So here are some of the signs of deficiencies that must not be ignored – and the meanings that are important to know:
When it is difficult to see in the dark: Vitamin A
Vitamin A is, as is known, an essential component for normal vision, immune system function, growth and development. Among other things, many studies conducted over the years have shown that it participates in processes that enable the retina to absorb light properly. Its main sources are fish, liver, dairy products and eggs, as well as orange and red vegetables and fruits that contain carotenoids that the body converts into vitamin A.
One of the first signs of a deficiency in it is difficulty with night vision. Before more serious complications appear, people report that they have difficulty adapting to darkness or seeing well in low-light conditions. This is sometimes an early warning sign that the vitamin reserves in the body are depleted and it is important to address it before the situation worsens.
Increased tendency for wounds and bruises: Vitamin K
Vitamin K is essential for proper blood clotting and also participates in maintaining bone health. It is found mainly in dark green vegetables such as spinach and broccoli, as well as in vegetable oils and grains.
One of the early signs of a deficiency in this important vitamin is an increased tendency for wounds and bruises, even after minor blows. When the body does not produce clotting factors efficiently, even a minor injury can leave a noticeable mark on the skin.
Tingling around the mouth: Calcium
Calcium is the most common mineral in the body and constitutes a central component in the structure of bones and teeth. Beyond that, and what people do not always know, is that it is essential for muscle contraction and the transmission of nerve signals. Dairy products are, as is known, a major source of calcium, but green vegetables and fish with bones also help reach the daily quota.
One of the first signs of calcium deficiency may be a sensation of numbness or tingling around the mouth and in the fingers. This is a reaction of the nervous system to changes in calcium levels in the blood and sometimes it is an early stage before the appearance of muscle contractions.
Sores in the mouth and fatigue: Folic acid
Folic acid, or vitamin B9, is essential for the creation of DNA and proper cell division. It is especially important during pregnancy and periods of growth and is found mainly in dark green vegetables, legumes, eggs, fortified grains and fruits.
One of the first signs of folic acid deficiency is the appearance of canker sores or sores in the mouth. Later, fatigue and weakness may also appear due to impaired production of red blood cells.
Swelling in the neck: Iodine
Iodine is an essential mineral for the production of thyroid hormones. It is found in iodized salt, seafood, seaweed and eggs. When the body does not receive enough iodine, the thyroid gland tries to compensate and may enlarge, a phenomenon known as goiter.
Swelling in the front area of the neck may be an early sign that the thyroid gland is working too hard in an attempt to produce hormones and therefore it is important to identify and treat the deficiency before the situation worsens.
Bleeding gums: Vitamin C
Vitamin C, or ascorbic acid, contributes significantly to the protection of blood vessels, skin, bones and connective tissues. Apart from citrus fruits that are known to contain it in high amounts, it is also found in peppers, strawberries and berries.
One of the classic signs of a deficiency in this important vitamin is bleeding gums. This is because it is essential for collagen production and when it is lacking, the tissues become more vulnerable to bleeding.
Cracks at the side of the mouth: Vitamin B6
Vitamin B6, or pyridoxine, is involved in the metabolism of proteins and carbohydrates and in the formation of hemoglobin. It can be found in beef, chicken, fish, legumes, bananas and whole grains.
One of the first signs of deficiency is painful cracks at the corners of the mouth. Sometimes this is accompanied by dryness or local inflammation and hints that the body is not getting enough of this important vitamin.
Bottom line, it is important to remember that a deficiency in nutritional components does not always manifest immediately in a serious disease, but rather in small signs that the body sends. Listening to these clues, alongside a varied diet rich in vegetables, fruits, whole grains, nuts and seeds, can prevent deterioration and restore balance long before the situation worsens and turns into a chronic disease.
