In today's era of technological and information explosion, influenced by media publicity or enticed by advertisements, more and more people, especially urban white-collar workers, are keen on taking nutritional supplements to aid their health. Some even take pills as a substitute for meals. This is truly a misconception.
Modern society is filled with intense competition, and work is stressful and demanding. Especially for white-collar workers, who mostly bear the heavy pressure of their jobs, they need to consume a large amount of nutrients daily. However, due to the nature of their work and irregular diet and daily routines, coupled with a lack of time for physical exercise, the exaggerated effects of certain advertising campaigns, and a lack of correct understanding of health, or excessive dieting by some young women to pursue a certain body shape, nutritional supplements have naturally become the best choice for the aforementioned groups.
Is taking more nutritional supplements healthy? No. Nutrition experts believe that if healthy people use nutritional supplements indiscriminately, it can harm their health. A balanced diet and appropriate exercise are the fundamental measures to ensure good health. As the saying goes, "all medicine has some toxicity," and this is no exception for nutritional supplements taken in excess. For example, pregnant women, lactating women, or the elderly may be prone to calcium deficiency, but excessive calcium supplementation can deposit in tissues outside the bones. If it deposits in the joints, it can cause joint pain; if it deposits in the muscles, it can form hard nodules; if it deposits in the heart, it can cause conduction disorders, leading to arrhythmia. Everyone knows that vitamins are beneficial to the human body, but if the daily intake of Vitamin A exceeds 3000 micrograms, it can damage the liver and also cause congenital defects in infants; an overdose of Vitamin E can cause a tendency to bleed; and large amounts of Vitamin C supplementation can form urate, cysteinate, or oxalate crystals in the body, leading to kidney stones.
Nutrition experts believe that normal people do not suffer from a lack of nutrients. People ingest large amounts of protein, fat, sugar, vitamins, minerals, and trace elements from their diet every day. Supplementation is only necessary in special circumstances or for specific populations. Moreover, it should be used correctly under the guidance of a doctor, and one should not use a single health supplement for long periods or in high doses. For normal people, there is no need to purchase expensive so-called nutritional supplements or health products, let alone take them in large quantities over the long term.
