Introduction
Given that there is no shortage of varied food groups available in developed countries or those with higher populations of upper socioeconomic status, the problem of nutrient deficiencies remains widespread across the globe. Common deficiencies are still prevalent even in developed countries. Read on to understand the nutritional importance and perspective.
Why Developed Countries Face Nutritional Deficiencies Too?
Even among developed countries, the rise in nutrient deficiencies is certainly concerning. According to nutrition experts, this is due to consuming improper, high, or empty calories from junk or refined foods. This trend, which is increasingly manifesting as fad diets (short-term, restrictive eating plans) even in developing countries, is largely driven by the commercial and increasing availability of junk or refined foods. These foods are major culprits and socioeconomic stressors affecting the nutritional health of individuals.
You might be wondering if eating junk food could make you nutritionally deficient. The answer is certainly yes, individuals who rely heavily on food choices rich in saturated fats, foods derived from refined oils and sugars, added sugars, increased caffeine content (more than 400 mg in a day), sugary or sports beverages, trans fats, creamy commercial or canned sauces, etc., are the ones most prone to developing nutrient deficiencies. According to medical researchers, when individuals stray from nutrient-dense calories obtained through a wholesome and balanced diet whether plant-based, animal-based, or a combination of both they instead consume empty calories from processed foods or alcoholic beverages, which deprive them of their daily nutritional needs.
Common assessments of diet and nutritional needs, especially in the United States and several other developed countries, show that multiple nutrients are lacking due to a market focus on processed foods rather than whole foods. Each nutrient deficiency is associated with specific clinical symptoms that individuals should identify at the earliest onset. Proper nutritional management by a registered healthcare professional or nutritionist can help prevent potentially life-threatening consequences caused by severe nutritional deficiencies and improper dietary habits or food choices. Let us explore below the common nutritional deficiencies in developed countries like the United States of America, the reasons behind them according to the World Health Organization (WHO) and the Second Nutrition Report, and information from the CDC (Centers for Disease Control and Prevention).
What Are the Most Common Nutritional Deficiencies in Developed Countries?
-
Iron: According to the World Health Organization (WHO), iron deficiency is the number one major nutritional disorder across many countries, especially when individuals do not obtain iron through a balanced diet and instead follow fad trends that encourage processed foods. Dietary iron exists mainly in two forms: heme and nonheme. Heme iron is commonly sourced from fish, seafood, red meats, poultry, and other animal proteins, while nonheme iron is an equally important source of plant-based iron found in foods like lentils and beans. Iron deficiency can lead to clinical fatigue, depression, cognitive stress or impairment, lowered immunity, and inflammation of the oral cavity.
-
Zinc: Zinc deficiency is also extremely common in developed countries. Zinc is abundant in lean meats, oysters, nuts, whole grains, poultry, dairy products, and fortified breakfast cereals. Zinc deficiency can lead to various clinical symptoms ranging from retarded growth, sexual impotence in men, and delayed wound healing to altered immune metabolism.
-
Iodine: Iodine deficiency is a major health issue, particularly affecting the thyroid gland. Iodine is essential for the production of thyroid hormones, and obtaining enough dietary iodine from sources like seaweed, shrimp, seafood, whole grains, and some dairy products ensures proper thyroid gland function. In children, even in developed countries, iodine deficiency can lead to possible neurocognitive consequences, impaired memory, loss of neurological functions, reduced productivity, and a lack of focus at work or school.
-
Vitamin D: Commonly known as the sunshine vitamin, it is crucial to obtain enough vitamin D from dietary sources that are whole foods. These include fatty fish like tuna, mackerel, and salmon, fish liver oils, cheese, medicinal mushrooms, fortified breakfast cereals, and egg yolks. Not consuming enough of these dietary elements can lead to a systemic deficiency of vitamin D. Vegans, in particular, may frequently encounter a vitamin D deficiency and should consult with a registered physician or nutritionist to create a personalized diet plan to improve vitamin D metabolism. Vitamin D is a vital regulator of bodily metabolism, playing a key role in calcium synthesis, bone mineralization, and sustaining cell immunity. Recognizing fatigue and clinical symptoms related to bone and muscle issues is useful in diagnosing underlying vitamin D deficiency.
-
Vitamin B12: One of the biggest challenges for purely vegan or vegetarian individuals in developed countries is the deficiency of vitamin B12, which is more commonly found in animal-based products like lean meats, fish, poultry, eggs, and dairy sources. However, vegans can counteract this challenge by including more fortified breakfast cereals or nutritional yeast-based products recommended by a registered physician or nutritionist to boost their vitamin B12 intake. Vitamin B12 is crucial for red blood cell and neurological metabolism in the body, as well as in the synthesis of DNA (deoxyribonucleic acid). Recognizing B12 deficiency symptoms or clinical signs of anemia, such as sudden or chronic weight loss, neurological tingling of the hands and feet, reduced appetite, constipation, depression, and poor memory, is important for timely management and preventing undue complications.
-
Vitamin C: Vitamin C is an essential immunity-boosting vitamin that is a major part of all global health diets. However, when individuals consume fewer whole food sources like citrus fruits, such as tomatoes, potatoes, and lemons, they are prone to this common deficiency. You can obtain vitamin C from vegetables like broccoli, red and green peppers, Brussels sprouts, and hydrating fruits like kiwi, strawberries, and cantaloupe, or even from fortified breakfast cereals. Common symptoms of scurvy resulting from vitamin C deficiency include inflamed oral mucous membranes, delayed wound healing, fatigue, stress, and loose teeth.
Conclusion:
To conclude, these essential nutrient deficiencies are common even in developed countries when individuals fail to obtain them from the recommended dietary sources. If you or your close ones are experiencing clinical fatigue, stress, or common symptoms of nutritional deficiencies, immediately contact your healthcare provider or nutritionist to gain insights on nutrition, receive lifestyle tips, and boost your systemic immunity.
