Part 2: Men's nutrients - walnut? 男士营养 - 核桃?

In America, prostate cancer is the second most common cancer in men,   next to skin cancer, and is the second-leading cause of cancer death in American men, behind lung cancer.

在美国，前列腺癌是男性第二最常见癌症，仅次于皮肤癌。也是美国男性的第二大癌症死亡原因，仅次于肺癌。

• The American Cancer Society estimates about 241,740 new cases and about 28,170 men will die of prostate cancer during 2012
• 1 in 6 men will be diagnosed with prostate cancer during his lifetime 
• 1 in 36 men will die of prostate cancer

• 据美国癌​​症协会估计，2012年约有 241,740个新病例，而约有28,170人将死于前列腺癌 
• 每6 位男士中，就有1名被诊断出患有前列腺癌 
• 每36名男士中，就有1名死于前列腺癌 

The most beneficial antioxidant for prostate health is lycopene (a red carotenoid in tomatoes). Do keep in mind that a cooked tomato is more bio-available, up to 4 times of a raw tomato. Cook your tomato!

番茄红素（一种在番茄的胡萝卜素）是对前列腺最有益的抗氧化剂。食用时请记得将番茄煮熟，因为熟番茄比生番茄更能被人体运用，高出4倍！

Another men food that is worth exploring is -- Walnut. Previous studies indicated healthy young men eating 75grams of walnuts a day would not result in weight gain but would improve their blood lipid levels (triglycerides, LDL, HDL). 75grams of walnuts is equivalent to about 8 whole walnuts (of cause size matters).

另一个男士最值得探讨的食物是 - 核桃。以往的研究显示健康的年轻男士每天吃75克的核桃，并不会导致体重增加，而会改善血脂（甘油三酯，低密度脂蛋白，高密度脂蛋白胆固醇）。 75克的核桃相当于8粒核桃仁 （当然因核桃的大小而异）。

Published in Biology of Reproduction, a study conducted by University of California, Los Angeles, the research team revealed that eating 75grams of walnuts a day improves the vitality, motility and morphology of sperm in healthy young men aged 21-35. Whether birth outcomes can be improved, will require further research.

发表在 Biology of Reproduction，由美国加州大学洛杉矶分校的研究发现，21岁至35岁的健康年轻男士，每天吃75克的核桃仁，可提高精子的生命力，活力和形态。至于可不可以因此提高生育力则需要进一步研究。
