  • High In Antioxidants
    Sesame seeds contain several antioxidants including sesamin and sesamolin as well as vitamin E. These antioxidants may help to prevent illnesses that can result from chronic oxidative stress such as cancer and cardiovascular disease.
  • High In Vitamin E
    Vitamin E can help boost the immune system, reduce the risk of heart attacks and protect the eyes from cataracts. Vitamin E is also believed to have anti-aging effects.
  • Bone Health
    Sesame seeds are a great source of calcium, zinc and several other vitamins and minerals that can help maintain proper bone density and prevent conditions that result from mineral deficiencies like osteoporosis.
  • Respiratory Health
    The magnesium in sesame seeds may help aid the respiratory system and treat certain side effects of asthma.
  • Anti-Inflammatory & Pain Relief
    Sesame seeds are a good source of copper, a mineral known to aid in pain relief from rheumatoid arthritis. Sesame seeds may help reduce swelling and have additional anti-inflammatory benefits as well.
  • Cancer Prevention
    One of the most important benefits of sesame seeds is their potential in the war against cancer. They are high in antioxidants as well as compounds called lignans, which have been found in lab tests to have anti-cancer properties. These substances may inhibit processes that contribute to cancer cell growth while inducing cancer cell death. Studies have shown eating sesame seeds to have positive effects on breast cancer treatment and one study associated daily sesame seed consumption with reduced risk of stomach cancer.
  • High In B-Vitamins
    The many complex B vitamins found in sesame seeds help the body extract energy from food and keep red blood cells healthy.
  • Lower Cholesterol
    The phytosterols in sesame seeds help the body absorb cholesterol and may help balance good and bad cholesterol levels.
  • Lower Blood Pressure
    The compounds in sesame seeds have been shown to relax blood vessels in lab tests and there by reduce blood pressure levels.

未來食物 Future Food?

今天,人們面對著食品價格上漲、人口增長和環境變化(如氣候變化)等問題,全球糧食供應正面臨鉅大考驗。這促使專家們、科學家們、還有相關組織和未來學家努力尋找解決問題的方法,著手研究我們的「未來食物」。

「未來食物」一: 昆蟲。建議,昆蟲的養殖成本遠低於飼養牛隻。荷蘭科學家的研究指出,昆蟲包含與肉類相同的營養價值,並含豐富的蛋白質。現時己有不少國家將昆蟲烹調美味佳餚。

「未來食物」二:利用聲波改變食物的味道。有研究指出,食物的味道會隨著味覺、嗅覺、甚至聽覺而改變;進食時聽著不同的聲音會改變食物的味道,比如說,人們聽著海浪聲進食會覺得食物比較新鮮。然而,食物和聲音的關係暫時只屬研究課題,還有待專家找出當中的關係。

「未來食物」三:人造肉。荷蘭的科學家們正在進行「人造肉」的研究,嘗試在實驗室製造「肉 」,並已成功製造出第一個「人造肉漢堡包」。 牛津大學的一項研究發現,從實驗室培殖出來的「肉 」與透過傳統屠宰動物而獲取的肉相比,其溫室氣體排放、能源和水的使用均顯著較低。但由於「人造肉」 尚未被測試,目前很難說明它會否成為全球糧食需求不斷增加 下而衍生的「未來食物」。

「未來食物」四:海藻。雖然海藻是食物鏈架構中屬最低層,但它們有助於解決糧食短缺的問題。 一些可持續發展食品行業更預測藻類養殖可以成為世界上最大的種植業。 海藻可能是很好的糧食來源,然而,專家們還未全面研究其所有用途。

很難想像二十年、三十年後的「未來食物」會是什麼樣,就讓我們拭目以待⋯⋯

Because of the rising food prices, growing population and environmental issues like climate change, experts, scientists, organizations and futurologist are dealing with the problem of how and what we are going to eat in the future.

It is proposed that insects cost less than raising cattle and according to scientists in a researching facility in the Netherlands, they contain the same nutritional value of meat and is also a good source of protein. Countries across the globe have already started to consume and include insects in some of their delicacies.

Sonic-enhanced food, food whose taste has been altered to fit our taste has also been proposed. It has been found that taste can be adjusted by changing the sonic of a background track. The relationship of food and sound is still a researching topic as experts are not yet sure what exactly happens in the brain to trigger the outcome.

Dutch scientists were able to grown “lab-grown” meat or “cultured meat” and produced the first “test-tube” burger. A study by “Oxford University found growing meat in a lab rather than slaughtering animals would significantly reduce greenhouse gases, along with energy and water use.” But because it is not yet commonly used nor tested, it would be difficult to make it a source of production in the future with the increasing demand for food.

Despite being under the food chain, Algae helps solve the problem of food shortages. “Some in the sustainable food industry predict algae farming could become the world’s biggest cropping industry.” Algae’s are good sources; however, experts have not yet done sufficient research to find out all its uses.

So, wait and see what we are really going to have in the future…

包裝如何協助減少食物浪費 The Naked Truth about How Packaging Can Help You Waste Less Food

 

package vs food waste

關於食物浪費,我們說過了不少。最近看到一個關於包裝如何協助減少食物浪費的信息圖表(infographic), 相當有趣。需然研究數據是以英國作為基礎,但也值得我們參考。

– 每年有多達 720萬噸食品和飲料被拋棄,佔我們買回家的所有食品的19%,足以填滿9個溫布萊球場

– 當中,有440萬公噸食物是還可食用的,生產他們需消耗 1700萬噸二氧化碳,即所有汽車加起來所排放的二氧化碳的五分一

– 有260萬公噸的食物因過了食用期而被丟棄,然而人們是花了67億元英鎊(約824億港元)購買回來的

– 88%的人認為包裝為環境帶來的問題比食物浪費大或差不多,然而,食品生產過程的碳排放量是包裝生產的15倍

– 61%的人認為,水果和蔬菜儲存在包裝下更快壞掉;只有13%的人知道,食品存儲在其原有的包裝更能保持新鮮。
