炎症性肠病患者的营养策略有哪些？
What nutrition strategies help inflammatory bowel disease?
IBD 活动期常需低渣、低纤维饮食减轻肠道刺激，缓解期逐步恢复均衡营养。注意纠正贫血、维生素D和钙缺乏。个体反应差异大，宜在营养科指导下调整。
Active IBD often needs low-residue, low-fiber food to reduce irritation, then a gradual return to balance in remission. Correct anemia, vitamin D, and calcium deficits. Responses vary, so adjust under a nutritionist.

慢性肾病患者如何限制蛋白质摄入？
How do chronic kidney disease patients restrict protein?
非透析期 CKD 患者常需适度低蛋白饮食以减轻肾脏负担，同时保证热量避免营养不良。优选优质蛋白如蛋、奶、鱼。具体限量应由肾内科与营养科共同制定。
Non-dialysis CKD patients often need moderately low protein to ease kidney load while keeping calories to avoid malnutrition. Prefer high-quality protein like eggs, dairy, fish. Exact limits should be set by nephrology and nutrition together.

什么是代谢综合征？为什么它值得重视？
What is metabolic syndrome, and why does it matter?
代谢综合征是指腹型肥胖、血压升高、空腹血糖升高、甘油三酯升高和HDL胆固醇偏低这5项中满足至少3项的状态，核心病理是胰岛素抵抗和内脏脂肪堆积。它使2型糖尿病和心血管疾病的风险成倍增加。好消息是它高度可逆：减重5%-10%、规律有氧运动、改善饮食结构就能显著改善各项指标，常作为治疗第一步。
Metabolic syndrome is defined as meeting at least three of five criteria: abdominal obesity, elevated blood pressure, elevated fasting glucose, high triglycerides, and low HDL cholesterol. Its core pathology is insulin resistance and visceral fat accumulation, and it roughly doubles the risk of type 2 diabetes and cardiovascular disease. The good news is that it is highly reversible: losing 5–10% of body weight, regular aerobic exercise, and improving diet can substantially improve every component, and are usually the first step in treatment.

为什么维生素D这么受关注？
Why is so much attention paid to vitamin D?
维生素D最重要的作用是促进钙的吸收和骨矿化，严重缺乏会让孩子患佝偻病、让成人骨软化或加重骨质疏松。它主要由皮肤在阳光照射下合成，饮食来源有限，因此在北方冬季或室内活动多的人群中常见不足。常规人群适量日晒和食物补充即可，是否需要额外补充应结合检测结果咨询医生。
Vitamin D's key role is promoting calcium absorption and bone mineralization; severe deficiency causes rickets in children and osteomalacia or worsening osteoporosis in adults. It is mostly synthesized in skin exposed to sunlight, with limited dietary sources, so deficiency is common in northern winters and among indoor lifestyles. Reasonable sun exposure and food intake suffice for most people; extra supplements should follow a doctor's advice based on testing.

地中海饮食为什么被认为对健康有益？
Why is the Mediterranean diet considered healthy?
地中海饮食以橄榄油为主要脂肪来源，配大量蔬菜水果、全谷物、豆类和坚果，鱼类适量、红肉和加工食品很少。著名的大型随机试验（PREDIMED）显示，坚持这种饮食能显著降低心血管事件风险。它也被认为是符合“抗炎”原则的可持续饮食模式。
The Mediterranean diet features olive oil as the main fat, plenty of vegetables, fruits, whole grains, legumes, and nuts, moderate fish, and little red meat or processed food. The landmark PREDIMED randomized trial showed it significantly reduces cardiovascular events. It is widely viewed as a sustainable, anti-inflammatory eating pattern.

为什么孕早期过量摄入维生素A可能伤害胎儿？
Why can too much vitamin A in early pregnancy harm the fetus?
维生素A的活性形式视黄酸参与胚胎形态发生，母体摄入过量（尤其动物肝脏、鱼肝油及维A补充剂）可穿过胎盘干扰发育，增加颅面、心脏和中枢神经系统的先天畸形风险。WHO建议孕妇以β-胡萝卜素等植物来源满足需要，并避免高剂量维A补充。计划怀孕者应先核对补充剂剂量。
The active form, retinoic acid, drives embryonic patterning, and excess maternal intake—especially from liver, fish-liver oil and supplements—can cross the placenta and disrupt development, raising the risk of craniofacial, heart and neural-tube defects. WHO advises meeting needs mainly from beta-carotene and avoiding high-dose retinol supplements. Women planning pregnancy should check supplement doses in advance.

Clonorchis sinensis encysts in freshwater fish and shrimp; eating them undercooked lets the larvae mature in the bile ducts, causing cholangitis, stones and even cholangiocarcinoma. It is a foodborne parasitic disease common in East Asia, with high rates where raw-fish dishes are popular. Thorough cooking is the most reliable prevention.

为什么维生素K2有助于把钙“引向骨骼”而非沉积在血管？
Why does vitamin K2 help direct calcium to bone rather than to vessel walls?
维生素K2是激活骨钙素等钙结合蛋白所必需的辅因子，活化的骨钙素把血钙抓进骨骼，同时抑制血管平滑肌的异常钙化。缺乏时钙更易沉积在动脉壁，与动脉硬化相关。维生素K1主要存在于绿叶菜中，而K2（甲萘醌）主要来自动物性食物与发酵食品（如纳豆）；一般饮食常K2不足，需均衡摄取。
Vitamin K2 is the cofactor that activates calcium-binding proteins like osteocalcin, which pulls blood calcium into bone and also checks abnormal calcification of vessel muscle. Without it, calcium more readily lands on artery walls, linking to hardening. Leafy greens are rich in vitamin K1 (phylloquinone), while K2 (menaquinone) comes mainly from animal foods and fermented foods like natto; usual diets often fall short of K2, so balance matters.
