Is Our Food Becoming Less Nutritious?
推荐理由
has a nice explanation.
说明
这是2018年由Veritasium发布的一部讲解,主题归在Nutrition & diet science。它讲的是crop nutrient decline这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Veritasium examines whether food has become less nutritious, weighing soil depletion, selective breeding and rising atmospheric CO2. It evidences nutrient decline even in weeds over a century and ties it to faster plant growth.这些读者给出的理由,核心是:HN people recommend it as a short, contextualizing explainer on declining crop nutrient density.讲法不绑某一条新闻,过几年仍然可以当材料看。从2019年到2022年,有2位不同的读者在2个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把crop nutrient decline变成能跟着复述的例子。
