我在日本长大,在那里我从小就被教导要将食物视为药物。 我的祖母今年 92 岁,她也将自己的长寿归功于吃对了食物。

日本是世界上一些寿命最长的人的故乡:现在有90,526 名百岁老人,即 100 岁及以上的人。 根据厚生劳动省 2022 年的一份报告,这是二十年前的五倍多。

日本偏远的小岛冲绳岛被选为世界上百岁老人最集中的地方。

作为一名遵循传统日本饮食的营养师,这里有五种我和我的家人每天吃的食物,以保持健康和长寿:

1. 日本红薯。

这些紫甘薯(日语称为“imo”)来自冲绳,通常作为零食或甜点食用。

它们富含健康的碳水化合物和花青素,这是一组存在于红色和紫色蔬菜中的抗氧化剂,具有抗衰老特性。

研究还表明,它们可以帮助改善血糖水平并降低患心血管疾病的风险。

2.味噌汤(酱汤)。

日本人的饮食中包含各种含有发酵食品的菜肴,味噌汤是其中一种很受欢迎的。 味噌是由发酵的大豆和谷物制成的糊状物(黄酱)。

发酵食品中的益生菌、活细菌或酵母可以帮助平衡我们的肠道健康并增强免疫系统。

一项研究发现,与很少食用这些食物的人相比,食用最多发酵大豆(如味噌、豆腐和豆豉)的男性和女性因各种原因早逝的几率要低 10%。

3.白萝卜。

根茎类蔬菜在日本烹饪中很受欢迎,并提供许多独特的健康益处。

众所周知,萝卜有助于预防感冒和增强免疫系统。 一个萝卜含有每日推荐摄入量的 124% 的维生素 C。

其他健康的根茎类蔬菜(在美国杂货店可能更容易找到)包括胡萝卜、甜菜、防风草和萝卜。

4.海带。

海藻富含铁、钙、叶酸和镁等重要矿物质。

每天吃它有助于在我的饮食中添加纤维。 摄入足够的纤维与降低患心脏病、中风、高血压和 2 型糖尿病的风险有关。

海藻还含有岩藻黄质和岩藻依聚糖等抗氧化剂,它们都具有抗炎、抗衰老和抗癌的特性。

5.鱼。

我总是在日常饮食中加入一些蛋白质,尤其是鲑鱼和金枪鱼等富含脂肪的鱼类。 鱼中的 omega-3 脂肪有助于降低血压、降低甘油三酯和缓解炎症。

在日本,我们经常在饭前说“itadakimasu”,意思是“我谦卑地接受”,以表达我们对动物和农民的感激之情。我相信这种正念饮食的做法有助于我们的健康和生活质量。

  1. Water and life

    Lightning is a dramatic display of electrical power, but it is also sporadic and unpredictable. Even on a volatile Earth billions of years ago, lightning may have been too infrequent to produce amino acids in quantities sufficient for life — a fact that has cast doubt on such theories in the past, Zare said.

    Water spray, however, would have been more common than lightning. A more likely scenario is that mist-generated microlightning constantly zapped amino acids into existence from pools and puddles, where the molecules could accumulate and form more complex molecules, eventually leading to the evolution of life.

    “Microdischarges between obviously charged water microdroplets make all the organic molecules observed previously in the Miller-Urey experiment,” Zare said. “We propose that this is a new mechanism for the prebiotic synthesis of molecules that constitute the building blocks of life.”

    However, even with the new findings about microlightning, questions remain about life’s origins, he added. While some scientists support the notion of electrically charged beginnings for life’s earliest building blocks, an alternative abiogenesis hypothesis proposes that Earth’s first amino acids were cooked up around hydrothermal vents on the seafloor, produced by a combination of seawater, hydrogen-rich fluids and extreme pressure.
    Yet another hypothesis suggests that organic molecules didn’t originate on Earth at all. Rather, they formed in space and were carried here by comets or fragments of asteroids, a process known as panspermia.

    “We still don’t know the answer to this question,” Zare said. “But I think we’re closer to understanding something more about what could have happened.”

    Though the details of life’s origins on Earth may never be fully explained, “this study provides another avenue for the formation of molecules crucial to the origin of life,” Williams said. “Water is a ubiquitous aspect of our world, giving rise to the moniker ‘Blue Marble’ to describe the Earth from space. Perhaps the falling of water, the most crucial element that sustains us, also played a greater role in the origin of life on Earth than we previously recognized.”

  2. It is appropriate time to make some plans for the future and it is time
    to be happy. I’ve read this post and if I could I wish to suggest you some interesting things or tips.
    Maybe you can write next articles referring
    to this article. I desire to read even more things about it!
