Food relates to Cancer

After reading an article related to toxic substances, it appears that these substances did appear in our food especially processed food or packaged food. An example is the DEHP that appears in the pearl of milk bubble tea and also instant noodles. 

There are some studies found that excess energy intake was more dangerous than excess fat intake in increasing tumor yield in various chemical carcinogenesis models; excess fat induced more tumors than excess carbohydrates or excess protein when tested in isocaloric diets. Excess body mass (high level of body mass index, BMI) is associated with increased risk of cancer of endometrium, breast and colon adipose tissue is rich in aromatase which converts androstenedione to estrone, thus increase the stimulation of endogenous steroid hormones (estrogens and testosterone). Therefore, maintaining an ideal body weight is very important to reduce risk of cancer and others type of diseases.

For example, if you are taking western dish or buffet, try avoid choosing chicken wings (fatty skin), charred part of meats or internal organs that cooked at high temperatures.There are foods contain substances such as heterocyclic amines (HCA) and polycyclic aromatic hydrocarbons (PAHs) that found in charred part of fried, grilled or barbeque meats (steak, hamburger patty, pork chops or bacon which is a cancer causing substances (carcinogens) ). HCAs form on the surface of meat from creatinine, amino acids, and sugars. PAHs can be found in other charred foods, as well as in cigarette smoke and car exhaust fumes. To reduce the risk of pancreatic cancer, again, reduce your meat consumption or adopt simple changes in meat preparation techniques that reduce or eliminate production of these compounds.

This article might sounds like a theory of a subject. However, there is actually no any food that can fully reduce the risk of getting cancer, but there are some sort of “good” combination of foods to maintain your health status. We always emphasize on balance meal. Balance meal is the best combination of foods to ensure adequate nutrients with appropriate amount of variety food intake. Don’t be a picky eater, get more variety in your dish especially vegetables, good source of complex carbohydrate as well as protein.

最近，我们在食物选购方面必须提高警惕，尤其是对有毒物质的出现，特别是加工食品及包装食品。在此之前，我们听到关于珍珠奶茶的问题, 最近又听到方便面的有毒事件。

根据一些研究显示过量的能量摄入比起多余的脂肪摄入量的危险性更能增加肿瘤产量，另外在同样的能量摄入里，摄入过多的脂肪比起碳水化合物或多余的蛋白质等热量饮食，会引起更多的肿瘤。过重（身体质量指数，BMI）会使癌症的风险增加，尤其是子宫内膜癌，乳腺癌和结肠癌，从而增加内源性类固醇激素（雌激素和睾丸激素的刺激）。因此，保持一个健康的体重可以帮助减少癌症和其他类型疾病的风险。

例如，如果你正在服用的西餐或自助餐，尽量避免选择的鸡翅（脂肪），烧焦部分。在高温下烤焦的肉类是不健康的食物，因为含有杂环胺（HCA）和多环芳香烃碳氢化合物（PAHs，通常出现在炸，烤或烧烤肉类（牛排，汉堡肉饼，猪排或腊肉，这是一种人类致癌物质））。HCAs的形式是表面上的肉肌酐，氨基酸和糖。多环芳烃，可以发现在其他烧焦的食物，以及在香烟烟雾和汽车排出的废气。为了降低患上胰腺癌的风险，最好还是减少肉类摄取，或通过简单的烹饪如蒸，焖，清炒等，以减少致癌物的产生。

其实没有一个单一的食物可以降低患癌症的风险，但有些食物的配合是能够保持你的健康状况处于“良好”。我们始终强调平衡膳食。平衡膳食可以确保足够的营养，适量地摄取各种食物是最好的组合。尽量不要挑剔食物的选择，多摄取各种蔬菜类，高纤维的碳水化合物以及蛋白质是必然的选择。
