很多人喜欢烟熏，预制火腿腊肠等等食品。

走进超市，货架上的香肠、可乐、零食常被轻易选走，可这些日常选择正悄然改写健康。“吃得开心”的背后，慢性炎症、胰岛素抵抗等问题在身体里潜伏。

 从亚硝酸盐到隐形糖，从反式脂肪到“健康光环”标签，食品工业的化学手段与生活习惯，将疾病风险包装成“适量即可”的谎言。

There Is No Safe Amount of Processed Meat to Eat

There is strong evidence that there is "no safe amount" of processed meat to eat, nutrition experts say in response to a new study on the connection between diet and the risk of major diseases, including cancer, type 2 diabetes and heart disease. The researchers also found elevated risks from the consumption of sugar-sweetened beverages and trans fatty acids.

Why are meats, drinks and fats linked to disease? Sugar-sweetened beverages and processed meat –– such as sausages, bacon, salami and burgers –– can increase inflammation, which plays a big part in a variety of chronic diseases. Processed meats are also often cured with nitrite, which is converted to carcinogenic nitrosamines in the stomach, said Dr. Gunter Kuhnle, professor of nutrition and food science at the University of Reading.

The problem with sugary drinks is that they are a quick way to consume large amounts of sugar, he added. Not only can that cause weight gain, but it also influences metabolic pathways that affect heart disease and diabetes risk, Kuhnle said. Trans fatty acids reduce levels of good cholesterol and increase the bad, which is known to increase the risk of plaque buildup in arteries and heart disease, he added.

Other potential connections to consider are that people who are more likely to eat processed meats, sugar-sweetened beverages and trans-fats are often also at a higher risk of diseases because of "lifestyle factors (smoking, lack of exercise), but also social factors such as education and income, chronic stress and limited access to health care," Kuhnle said. "It is very difficult to take these apart."

A sensible approach is to follow a varied and balanced diet that avoids excess, Kuhnle said. A good diet isn't just about what to avoid. It's also important to get good nutrients. Wider research has shown us that overall dietary patterns that include higher consumption of fruit and vegetables, whole grains, legumes, nuts and fermented dairy products like yogurt are good for health and longevity.

答案与解析

1. 答案：D
解析：文章开篇即提出“加工肉制品没有安全食用量”，随后又指出含糖饮料和反式脂肪酸也会增加患病风险，核心围绕这三类食物的安全问题展开。A选项错误，文中明确加工肉制品并非重大疾病的唯一诱因；B选项是文章结尾提到的细节建议，并非主旨；C选项无依据，文章未对含糖饮料和加工肉制品的危害进行对比。因此D选项符合主旨。

2. 答案：B
解析：根据第二段内容，冈特·库恩勒博士提到“加工肉制品常使用亚硝酸盐腌制，亚硝酸盐在胃中会转化为致癌的亚硝胺”，这是加工肉制品与疾病相关的直接原因。A选项是反式脂肪酸的作用，与加工肉制品无关；C选项是导致疾病的其他社会和生活方式因素，并非加工肉制品本身的原因；D选项是含糖饮料的特点，并非加工肉制品。因此B选项正确。

3. 答案：C
解析：第三段明确说明“含糖饮料会影响代谢途径，进而增加患心脏病和糖尿病的风险”。A选项错误，文中提到含糖饮料是“快速摄入大量糖分”的方式；B选项错误，除体重增加外，含糖饮料还会影响代谢途径；D选项是反式脂肪酸的作用，与含糖饮料无关。因此C选项正确。

4. 答案：C
解析：最后一段中，库恩勒博士提出建议“遵循多样化、均衡的饮食，避免过量摄入，同时摄入足够的有益营养”。A选项错误，文中强调“良好饮食不仅是避免某些食物”；B选项与原文相悖，文章明确建议减少加工肉制品、增加蔬果摄入；D选项错误，酸奶等发酵乳制品是健康饮食的一部分，而非唯一依赖。因此C选项正确。
