Eating organic food will not make you healthier, according to researchers at Stanford University, although it could cut your exposure to pesticides.
They looked at more than 200 studies of the content and associated health gains of organic and non-organic foods. Overall, there was no discernible difference between the nutritional content, although the organic food was 30 percent less likely to contain pesticides.
The research, published in the journal Annals of Internal Medicine, looked at 17 studies comparing people who ate organic with those who did not and 223 studies that compared the levels of nutrients, bacteria, fungus or pesticides in various foods, including fruits, vegetables, grains, meats, milk and eggs.

Fruit and vegetables contained similar amounts of vitamins, and milk the same amount of protein and fat — although a few studies suggested organic milk contained more omega-3. Organic foods did contain more nitrogen, but the researchers say this is probably due to differences in fertilizer use and ripeness at harvest and is unlikely to provide any health benefit.

根據史丹福大學研究人員,吃有機食物不會讓你更健康,但可能減少你和殺蟲劑的接觸。

他們檢視針對有機與非有機食品成分與相關健康益處的兩百多份研究,整體而言,兩者間的營養成分並沒有可識別的不同,但有機食物含殺蟲劑的機率少三成。
這份刊登在《內科醫學誌》期刊的研究,檢視比較吃有機食物與沒吃有機食物者的十七份研究,以及比較水果、蔬菜、穀類、肉類、牛奶和蛋等多種食物中,營養物、細菌、真菌或殺蟲劑含量的二百二十三份研究。
蔬果的維生素含量類似,牛奶的蛋白質與脂肪含量相同,但少數研究顯示有機牛奶的omega-3含量更多。有機食品確實含有較多氮,但研究人員說,這可能是因為肥料使用與收成時的成熟度不同,不可能提供任何營養益處。

The strongest earthquake to hit Taiwan in 25 years killed at least 16 people and damaged dozens of buildings, but the destruction was largely contained thanks to decades of preparedness work. Taiwan sits on the “Ring of Fire,” an arc of intense seismic activity along the Pacific Rim, and — much like neighboring Japan — has a long history of catastrophic quakes. How does April 3 compare with other recent quakes? The April 3 earthquake, which measured 7.4 on the moment magnitude scale, was felt across Taiwan. It was the most severe since a 7.6 magnitude quake in 1999 killed
Around the time of the Dragon Boat Festival in June, the streets of Taiwan are filled with the delightful aroma of zongzi, a traditional snack made of sticky rice wrapped in leaves. The leaves are folded into a cone and then filled with sticky rice and other ingredients such as braised pork belly, peanuts and salted duck egg yolks. The filled leaves are then tightly tied with kitchen twine and ready for cooking. 每到六月端午時節,街頭巷尾就會飄出粽子的香氣。粽子是將糯米包進粽葉的傳統美食,先將粽葉折成圓錐狀塞入糯米,以及紅燒肉、花生、鹹鴨蛋黃等配料,用棉線綁緊後即可烹煮。 Dragon Boat Festival (n. phr.) 端午節 aroma
Everyone has seen a piece of fruit turn brown after being cut. Have you ever wondered why that happens? It is a common phenomenon that occurs due to a chemical reaction called enzymatic browning. The appearance, flavor and nutritional value of the fruit are all affected by this reaction. Some fruits, such as apples, pears, bananas, avocados and peaches, are more prone to enzymatic browning than others. These fruits contain high levels of an enzyme called polyphenol oxidase, or PPO for short. __1__ This causes a chain of chemical reactions that ultimately transforms the phenolic compounds into
A: As well as Eid al-Fitr, Southeast Asia is celebrating the Water Festival this week. B: And this year, Thailand is expanding the celebration between April 12 and 16 for the event, officially known as the Songkran Festival, expecting to make 24.3 billion Thai baht in tourism revenue. A: Does Taiwan celebrate the Water Festival? B: Some local cities and counties do have similar activities. A: Let’s go experience the festival then. A: 除了「開齋節」外,東南亞「潑水節」本週也盛大登場! B: 泰國今年從4月12日到16日擴大「宋干節」連假,預估觀光收入可高達243億泰銖。 A: 台灣會慶祝「潑水節」嗎? B: 有些縣市會舉辦類似活動。 A: 那我們也去體驗一下吧。 (By Eddy Chang, Taipei Times/台北時報張聖恩)
