(Central News Agency reporter Chen Chieh-ling, Taipei, 4th) With rising health awareness, achieving a standard physique is a life pursuit for many. Many choose methods like 168 fasting and low-calorie diets. Nutritionists warn that these special dietary patterns hide pitfalls; once nutrition is imbalanced, it can cause thyroid dysfunction, affecting metabolism.
Liu Jieyun, a nutritionist at Lianan Preventive Medicine Institution's Lianqing Clinic, reminded today via a press release that thyroid problems, often referred to as the 'endocrine commander' in the body, are common during weight management or reduction. When the body faces long-term calorie deficiency, it enters starvation mode, activating a conservation mechanism that slows down overall metabolism, potentially inhibiting thyroid hormone production.
When the thyroid's rhythm is disturbed, it's not just about metabolic speed; it's closely related to the overall physical state and can lead to daily feelings of fatigue. Liu Jieyun said that when it comes to thyroid care, many people immediately think of seaweed because it is rich in iodine. In fact, besides iodine, many other nutrients are involved in thyroid hormone synthesis, and a balanced and diverse daily diet should still be prioritized.
Liu Jieyun stated that the body's ability to synthesize thyroid hormones is closely related to its nutritional status. Zinc, iodine, iron, selenium, and vitamins A, C, D, E, B2, B3, among others, are important nutrients involved in thyroid hormone production. Sources of these nutrients include oysters, shellfish, red amaranth, Brazil nuts, egg yolks, carrots, guava, kiwi, salmon, sun-dried mushrooms, olive oil, and almonds.
Liu Jieyun pointed out that groups needing to pay attention to thyroid dysfunction are not only those on special diets. For most people who frequently eat out, a long-term single-food diet can also easily lead to imbalanced nutrient intake, thereby affecting normal thyroid function.
In addition, long-term stress, exposure to environmental toxins like plasticizers, heavy metals, imbalanced gut flora, or habits like smoking and drinking can also interfere with the normal production of thyroid hormones. Liu Jieyun suggests early detection and intervention through comprehensive thyroid examinations, such as thyroid ultrasound, which can lead to adjustments. (Edited by Chen Ching-fang)
