2024考研英语同源外刊:这些跟健康有关谣言知道几个?
Myth No. 1: Fresh fruits and vegetables are always healthier than canned, frozen or dried varieties. Despite the enduring belief that “fresh is best,” research has found that frozen, canned and dried fruits and vegetables can be just as nutritious as their fresh counterparts. One caveat: Some canned, frozen and dried varieties contain sneaky ingredients like added sugars, saturated fats and sodium, Dr. Bleich said, so be sure to read nutrition labels and opt for products that keep those ingredients to a minimum.
误区一:新鲜水果和蔬菜总是比罐装、冷冻或脱水的水果和蔬菜更健康。尽管人们一直认为“新鲜的是较好的”,但研究发现,冷冻、罐装和脱水的蔬菜,同新鲜水果蔬菜一样有营养。需要注意的是,布莱奇说,一些罐装、冷冻和脱水的蔬果含有添加糖、饱和脂肪和钠等有害成分,所以一定要阅读营养标签,选择将这些成分控制在较低限度的产品。
Myth No. 2: All fat is bad. In reality, Dr. Surampudi added, not all fats are bad. While certain types of fats, including saturated and trans fats, can increase your risk for conditions like heart disease or stroke, healthy fats — like monounsaturated fats (found in olive and other plant oils, avocados and certain nuts and seeds) and polyunsaturated fats (found in sunflower and other plant oils, walnuts, fish and flaxseeds) — actually help reduce your risk. Good fats are also important for supplying energy, producing important hormones, supporting cell function and aiding in the absorption of some nutrients.
误区二:所有脂肪都是不好的。实际上,苏兰普迪还说,并不是所有的脂肪都是有害的。虽然某些类型的脂肪,包括饱和脂肪和反式脂肪,会增加罹患心脏病或中风等疾病的风险,但健康的脂肪——比如单不饱和脂肪(存在于橄榄油和其他植物油、鳄梨和某些坚果和种子中)和多不饱和脂肪(存在于向日葵和其他植物油、核桃、鱼和亚麻籽中)——实际上有助于降低风险。好的脂肪也有助于提供能量、产生重要的激素、支持细胞功能和帮助吸收某些营养物质。
Myth No. 3: ‘Calories in, calories out’ is the most important factor for long-term weight gain. It’s true that if you consume more calories than you burn, you will probably gain weight. And if you burn more calories than you consume, you will probably lose weight — at least for the short term. But the research does not suggest that eating more will cause sustained weight gain that results in becoming overweight or obese. “Rather, it’s the types of foods we eat that may be the long-term drivers” of those conditions, said Dr. Dariush Mozaffarian, a professor of nutrition and medicine at the Friedman School of Nutrition Science and Policy at Tufts University.
误区三:“卡路里摄入大于消耗”是长期体重增加的最重要因素。的确,如果你摄入的卡路里比燃烧的卡路里多,你可能会增重。如果你燃烧的卡路里比摄入的卡路里多,就可能会减肥——至少在短期内是这样。但研究并不表明吃得多会导致体重持续增加,从而导致超重或肥胖。塔夫茨大学弗里德曼营养科学与政策学院的营养与医学教授达里什·莫扎法里安说,“相反,我们吃下的食物类型可能是导致这些情况的长期驱动因素”。
Ultraprocessed foods — such as refined starchy snacks, cereals, crackers, energy bars, baked goods, sodas and sweets — can be particularly harmful for weight gain, as they are rapidly digested and flood the bloodstream with glucose, fructose and amino acids, which are converted to fat by the liver. Instead, what’s needed for maintaining a healthy weight is a shift from counting calories to prioritizing healthy eating overall — quality over quantity.
相反,保持健康体重所需要的,与其说是计算卡路里,不如说是先考虑健康饮食——质量大于数量。
Myth No. 4: Plant milk is healthier than dairy milk. There’s a perception that plant-based milks, such as those made from oats, almonds, rice and hemp, are more nutritious than cow’s milk. “It’s just not true,” said Kathleen Merrigan, a professor of sustainable food systems at Arizona State University and a former U.S. deputy secretary of agriculture. Consider protein: Typically, cow’s milk has about eight grams of protein per cup, whereas almond milk typically has around one or two grams per cup, and oat milk usually has around two or three grams per cup. While the nutrition of plant-based beverages can vary, Dr. Merrigan said, many have more added ingredients — like sodium and added sugars, which can contribute to poor health — than cow’s milk.
误区四:植物奶比牛奶更健康。人们认为植物奶,例如由燕麦、杏仁、大米和大麻籽制成的奶,比牛奶更有营养。“这是错误的,”亚利桑那州立大学可持续食品系统教授、前美国农业部副部长凯瑟琳·梅里根说。就拿蛋白质来说:通常,一杯牛奶(约236毫升)含有约八克蛋白质,而杏仁奶通常每杯含有约一两克蛋白质,燕麦奶每杯通常含有约两三克蛋白质。梅里根说,虽然植物性饮料的营养成分可能有所不同,但许多植物性饮料比牛奶含有更多的添加成分,例如钠和添加糖,这些成分可能不利于身体健康。
