字幕英文翻譯 第一段 English translation of the video transcript ⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇ Superfoods refer to a group of nutrient-dense and health-beneficial foods. Although in recent years, the term "superfood" has taken on a somewhat over-marketed impression, we cannot deny that being listed as a superfood signifies not only a wide variety of nutrients but also high nutrient density with multiple health benefits. However, every time I see articles introducing superfoods, it always seems to focus on the same types of food. Let me list a few here: quinoa, avocado, berries, pomegranates, cocoa powder, chia seeds, flaxseeds, kale, and many others. I believe that those who talk about or market superfoods would not deny these foods. But when a group of almost "celebrity" foods steals the spotlight, it means another group of foods is destined to be overlooked. They may occasionally get some coverage in health news, but most of the time, they are ignored. Even when a typhoon comes, and people rush to the supermarket to buy all the fresh food, you can still find them lying lonely on the shelves, looking quite pitiful. So today, I have chosen five long-overlooked great foods. Not only are they rich in nutrients, but they also have multiple health benefits, making them perfect for those who want to eat healthy and fight cancer on a budget. However, I want to add that the five foods I chose are more applicable to Taiwan, and they are ones I personally eat very often. Taiwan's climate and natural environment are ideal for their growth, so they are plentiful and of high quality. But in other places, it might be different, so if you're from another country, feel free to leave a comment below and share some nutrient-rich yet affordable foods from your area! Let’s begin. The first low-key, cancer-fighting food is black beans. First, let me tell you about black beans' background. They are actually the same species as soybeans (Glycine max), commonly known as soybeans. The plant has skins in various colors, and if you categorize them carefully, there are said to be nearly 3,000 different colors. Among them, yellow-skinned soybeans and black-skinned black beans are commonly used in daily diets, giving us the impression that soybeans are divided into yellow and black beans. But in reality, there are more than just these two. Additionally, before soybeans are fully mature, their pods are green, and the beans inside are also green. These young, hairy soybeans are called edamame. So, they are all part of the same family. If you split a black bean in half, you’ll see that the inside, or cotyledon, is either yellow or green. This cotyledon is a vital part of the seed, storing many nutrients. When we eat black beans, we usually choose green-cotyledon black beans, as they have much higher nutritional value than yellow-cotyledon black beans. Not only are green-cotyledon black beans better than yellow-cotyledon ones, but they are also much more nutritious than yellow soybeans. Both are rich sources of protein, dietary fiber, and essential minerals such as potassium, calcium, and magnesium. But when it comes to anthocyanins, folic acid, vitamin A, and beta-carotene, black beans far surpass yellow soybeans. However, for a food like black beans that must be cooked thoroughly, emphasizing heat-sensitive phytonutrients isn’t very meaningful. The nutrients mentioned earlier, except for vitamin A, like anthocyanins, folic acid, and beta-carotene, are quite heat-sensitive and will largely be lost once you cook or fry the black beans. This is similar to emphasizing the vitamin C content in bitter melon or broccoli. If you have to cook the food in the end, it doesn’t matter how much vitamin C it has when raw. When it comes to black beans, what is particularly worth mentioning is a more heat-resistant active compound called saponins. Soybeans are rich in saponins, and among all soybeans, black beans contain the most, about two to three times more than yellow soybeans. So, what are saponins? Simply put, they are molecules that are both water- and fat-soluble, allowing water and fats, two liquids that don’t typically mix, to emulsify. In chemistry, saponins are a type of surfactant. If a plant contains saponins, it can be made into a natural cleaning agent, such as black bean shampoo or body wash. Of course, smart humans don’t just use saponins as cleaning agents. Since many saponins exist in edible plants, we’ve started studying their health benefits. Black bean saponins, for example, can lower cholesterol, prevent fat oxidation, and maintain vascular flexibility. In addition to benefiting cardiovascular health, black bean saponins can inhibit the division of colon cancer cells. Epidemiological studies have also found that the more soybeans premenopausal women consume, the lower their risk of colon cancer. However, because black beans must be thoroughly cooked, people with chronic kidney disease are advised not to eat them daily, as their high potassium and phosphorus content can burden the kidneys. If you tend to experience bloating, it's recommended to soak the black beans overnight before cooking, as this reduces oligosaccharides and decreases the chances of bloating.
