Urinary sugars as biomarker for dietary sugar intake; a prospective population study

虽然人们普遍认为饮食中摄入过多的糖对健康有害，但令人惊讶的是，几乎没有科学证据支持这一观点。这可能与我们难以测量饮食中糖的摄入量有关，因为它在食物中广泛存在且含量不一。我们的研究表明，尿液中的糖排泄（蔗糖和果糖）（而不是葡萄糖，这可能预示着糖尿病）是饮食中糖摄入量的一个很好的反映。我们建议研究膳食糖摄入量是否与心脏病、中风和糖尿病等与衰老相关的慢性疾病的长期风险有关，用尿糖排泄量来评估，研究对象是25,000名年龄在40-79岁之间的男性和女性，他们从1993年到现在一直被跟踪调查健康状况。这可能有助于我们更好地了解如何预防与衰老相关的慢性疾病。

Though it is commonly believed that a high dietary intake of sugar is bad for health, there is surprisingly little scientific evidence to support this. This may relate to our difficulty in measuring dietary sugar intake given its widespread presence and variable amounts in foods. Our work suggests that sugar excretion (sucrose and fructose) in the urine (as opposed to glucose, which is may indicate diabetes) is a good reflection of dietary sugar intake. We propose to examine whether dietary sugar intake, as assessed using urine sugar excretion is related to long term risk of chronic diseases associated with ageing such as heart disease, stroke and diabetes in 25,000 men and women aged 40-79 who have been followed up between 1993 to the present for health. This may help us understand better how to prevent chronic diseases associated with ageing.
