There are many reasons people go vegan, from wanting to be healthier, to reducing their environmental footprint, to concerns about animal welfare.
人們吃素的原因有很多種，例如，想要變得更健康，減少對環境的影響，以及關注動物福祉。
No matter what the reason, many people find it difficult to meet the nutrient intake targets for specific vitamins and minerals while on a vegan diet. These include vitamin B12, iron, calcium, and iodine.
不論大家吃素的原因是什麼，許多人發現，吃素無法滿足對特定維生素和礦物質的營養攝入量的需求，其中包括維生素B12、鐵、鈣和碘。
min B12
維生素B12
Vitamin B12, or cobalamin, is essential for making red blood cells, DNA (your genetic code), fatty acids located in myelin (which insulate nerves), and some neurotransmitters needed for brain function.
維生素B12也就是鈷胺素，它是形成紅細胞、DNA（你的基因序列）、髓磷脂（隔離神經的物質）中的脂肪酸以及發揮大腦機能所需的部分神經介質的必要物質。
Vitamin B12 is stored in the liver, so a deficiency probably won't happen in adults in the short term.
維生素B12可以貯存在肝臟中，所以成年人短期內不會出現維生素B12缺乏的症狀。

鈣
Calcium is needed to develop and maintain the skeleton bones, and is stored in the teeth and bones. It is also essential for heart, muscle and nerve function.
鈣是骨骼生長髮育所需的元素，它可以貯存在牙齒和骨骼中。它也是發揮心臟、肌肉和神經功能的必要元素。

Iodine is needed to make thyroxine, a thyroid hormone used in normal growth, regulation of metabolic rate, and development of the central nervous system. Iodine is concentrated in the thyroid gland.
碘是合成甲狀腺素所需的元素，這是一種甲狀腺激素，可以控制並促進正常的新陳代謝，也有助於中樞神經系統的發育。碘主要貯存於甲狀腺中。
鐵
Iron is needed to make haemoglobin in red blood cells, which carries oxygen around your body.
鐵是合成血紅蛋白所需的元素，而血紅蛋白是人體內運輸氧的物質。
Iron is also needed for the production of energy in your muscles, and for concentration and a healthy immune system.
鐵也是肌肉產生力量所需的元素，而且它可以提高人體免疫力並有助於維持免疫系統的健康。
