所謂Trans Fat，是指一些加工了的菜油。原來，動物油，例如豬油、牛油，之所以會凝結，是因為其中的脂肪酸（Fatty Acid）都屬於一種不會與氧氣化合的飽和脂肪酸。植物油中的則是一類屬不飽和的脂肪酸。不飽和脂肪酸的分子式因其中氫原子的方位不同，可分為順式及反式的「鍵結」。天然的不飽和脂肪酸幾乎全部屬順式，在動物體內能代謝。人造的反式脂肪，耐高溫、不易變質（產生「益」味）、能存放更久；所以食品業者以植物油為原料，經部分氫化處理，造出反式脂肪。但這種油一旦進入人體，大都滯留其內，能增加罹患多種疾病的機率，包括心臟病、癌症、糖尿病、肝病、不育等。
比反式脂肪更不可思議的人工炸油，是寶潔（Procter & Gamble, P&G）在1968年發明的Olestra（商業名稱Olean）。這是一個蔗糖和脂肪酸的化合物，在1996年經FDA批准出售。不過由於很多人吃過Olestra炸的薯片後，都有肚瀉的徵狀，理由是腸內有太多油，所以這個人造炸油的銷路，一直差強人意。
在過去的五、六十年，化學工業創出了數之不盡的人造化合物，包括塑膠PVC（Poly Vinyl Chloride）、殺蟲劑DDT（Dichloro Diphenyl Trichloroethane）、的確涼（Dacron）的主要成分PET（Polyethylene Terephthalate）、防曬油的主要成分MBC（Methyl Benzylidine Camphor）、洗衣粉的主要成分NPE（Nonyl Phenol Ethoxylates）等。現在很多學者均提出有力證據，指出這些人造成分對人體有害，例如NPE分解後的NP，會引起乳腺細胞增生（Reprod. Biol. Endocrinol. Vol.4 pp.49-50）。下一次去買洗衣粉時，不妨試找一些不含NPE的牌子。

人工智能研究乳腺細胞增生治療方法
乳腺細胞增生是一種常見的疾病，通常通過手術和藥物治療來緩解癥狀。人工智能技術可以輔助醫生進行診斷和治療，具有以下幾種應用方式：
圖像識別：人工智能可以通過對乳腺X線照片、核磁共振圖像等醫學影像的分析，識別出乳腺細胞增生的病變區域和範圍，幫助醫生準確定位病變部位，指導手術治療。
數據分析：人工智能可以通過對大量的病歷數據、病理學數據、臨床試驗數據等進行分析，挖掘出乳腺細胞增生的病因、發病機制和治療效果，指導醫生選擇最佳的治療方案和藥物。
藥物研發：人工智能可以通過對大量的化合物庫進行篩選，找到具有潛在治療效果的藥物，並預測藥物的藥代動力學和毒理學特性，提高藥物研發的效率和準確性。
個性化治療：人工智能可以根據患者的基因型、生物標志物等個體化信息，預測病情發展趨勢和治療效果，為醫生提供個性化的治療方案。
總之，人工智能在乳腺細胞增生治療方面具有廣泛的應用前景，可以輔助醫生進行診斷、治療和藥物研發，提高治療效果和病人的生活質量。

Trans fat is a type of unsaturated fat that has been artificially produced through the process of hydrogenation. Hydrogenation is a chemical process that adds hydrogen atoms to liquid vegetable oils, turning them into solid or semi-solid fats. The process is used to increase the shelf life and stability of the oils, making them useful for a variety of food products, including baked goods, fried foods, and snack foods.
Trans fats are different from other types of unsaturated fats, such as monounsaturated and polyunsaturated fats, which are found naturally in foods like nuts, seeds, and fatty fish. Unlike these healthy fats, trans fats have a negative effect on health and have been linked to a range of health problems, including heart disease, stroke, and type 2 diabetes.
The main reason why trans fats are so harmful is that they raise LDL (bad) cholesterol levels and lower HDL (good) cholesterol levels. This can lead to a buildup of plaque in the arteries, increasing the risk of heart disease and stroke. In addition, trans fats can also cause inflammation in the body, which is a risk factor for a variety of health problems, including heart disease, stroke, and type 2 diabetes.
Trans fats are also harmful because they interfere with the body's ability to absorb essential fatty acids, which are necessary for good health. They can also cause the body to become resistant to insulin, increasing the risk of type 2 diabetes.
To reduce the risk of health problems associated with trans fats, it is important to limit your consumption of them. The best way to do this is to read the labels of the foods you eat and look for products that are free of trans fats. Avoid foods that contain partially hydrogenated oils, as these are a source of trans fats.
In addition to reading labels, it is also important to eat a healthy diet that is rich in fruits, vegetables, whole grains, and lean protein. This type of diet can help to reduce the risk of heart disease, stroke, and type 2 diabetes, and it can also help to improve gut health.
In recent years, the food industry has made progress in reducing the amount of trans fats in foods. In 2015, the Food and Drug Administration (FDA) announced that partially hydrogenated oils are no longer generally recognized as safe, and food companies have been working to reformulate their products to eliminate trans fats.
However, not all foods have been reformulated, and some products still contain trans fats. It is important to continue to be vigilant about checking labels and avoiding foods that contain trans fats.
In conclusion, trans fats are a type of unsaturated fat that have been artificially produced through the process of hydrogenation. They have a negative effect on health, raising LDL (bad) cholesterol levels and lowering HDL (good) cholesterol levels, and have been linked to a range of health problems, including heart disease, stroke, and type 2 diabetes. To reduce the risk of health problems associated with trans fats, it is important to limit your consumption of them and to eat a healthy diet that is rich in fruits, vegetables, whole grains, and lean protein.
