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.

When we mention goji berries, we often think of dishes like longan jujube tea, ginseng chicken soup, or stir-fried veggies with sesame oil. Why? Because goji berries often play a supporting role in these dishes. But if you think that’s all goji berries are good for, you’re completely mistaken. Goji berries are often overlooked as a superfood, so don’t just use them to brew tea. Next time, wash them thoroughly, don’t cook them, soak them in cold water to soften them, and then eat them directly. Goji berries are rich in vitamins C and B, as well as calcium and iron. Additionally, their beta-carotene content is three times that of carrots, and their lutein is five times that of carrots. While the anthocyanin content in red goji berries is comparable to that in blueberries, black goji berries, which are rarer, contain up to 20 times the anthocyanins of blueberries. However, since black goji berries cannot yet be mass-cultivated, they are expensive. If you can't find them, just eat red goji berries. Besides these nutrients, goji berry polysaccharides are another component that has gained attention in recent years. They can manipulate white blood cells to attack cancer cells, such as breast cancer cells. Why is manipulating white blood cells important? Because in cancer patients, not all white blood cells are good. Tumors have the ability to release chemicals that encourage some white blood cells to turn against us, helping cancer cells grow and divide, and even helping tumors build new blood vessels to supply them with nutrients. In cancer medicine, we call these traitorous white blood cells M2 TAMs (tumor-associated macrophages). On the other hand, the body can also issue commands to release chemicals that turn another group of white blood cells into tumor-fighting cells. We call these loyal soldiers M1 TAMs. Goji berry polysaccharides play a role here by converting the already traitorous M2 cells back into M1, helping the body fight the tumor. In cancer treatment, many drugs are being developed to strengthen the tumor-fighting effect of M1 cells. You only need to eat about 20 to 30 goji berries a day, as they are a nutrient-dense food, so you don’t need to eat a lot. The key is to avoid heating them, as most of their phytonutrients are heat-sensitive. Also, be mindful that goji berries are relatively high in sugar, containing 10 to 20 grams of sugar per 100 grams, so if you eat too many, you may unknowingly consume too much sugar. Lastly, news reports occasionally mention excessive pesticide residues on goji berries, so be cautious. Although government agencies regularly test goji berries on the market, the safest approach is still to rely on ourselves. Before eating goji berries, rinse them under running water for five minutes, drain them, and ideally blanch them in hot water for a few seconds to remove harmful substances. While washing, observe the color of the water-if it turns bright red, it’s likely food coloring, indicating low-quality goji berries that are best avoided. The third great, overlooked food is sweet potato leaves. Every living organism continuously produces toxic substances during its operations. Among these toxins, free radicals-molecules that oxidize other molecules and damage bodily functions-are particularly harmful. Of course, the body can clear free radicals, primarily in the liver. But when the amount of free radicals exceeds the body’s capacity, external help is needed to remove the excess. Polyphenols from food are especially effective in helping the body eliminate free radicals, so the total polyphenol content (TPC) of a food is often used to represent its nutritional value and its potential for preventing diseases like cardiovascular and neurodegenerative diseases and cancer. Among all foods, dark green vegetables have some of the highest TPC levels. In many comparative studies on dark green vegetables, sweet potato leaves consistently rank among the top, often coming in first. Kaohsiung Veterans General Hospital once analyzed the lifestyles of 300 lung cancer patients and another 600 controls to determine which dietary habits particularly reduce lung cancer risk. The results showed that people who ate more of two specific vegetables had significantly lower chances of developing lung cancer-one was sweet potato leaves, and the other was garland chrysanthemum. This shows that regularly eating foods rich in antioxidants and high in polyphenols, like sweet potato leaves, is incredibly beneficial for health. Additionally, sweet potato leaves are rich in calcium, lutein, dietary fiber, and vitamins A, D, and K. I would like to specifically mention vitamin K here. The K2 in vitamin K needs to work together with vitamin D3 for the calcium we consume to be efficiently absorbed into our bones. First, D3 helps calcium get absorbed from the intestines into the bloodstream, and then K2 allows this calcium in the blood to enter the bones. This is why it’s often recommended to take D3 and K2 together when using supplements. What's even better is that sweet potato leaves rarely have issues with pests, so they almost never require pesticides. However, there have been cases where excessive pesticide residues were detected on sweet potato leaves, though these are rare. So, before cooking them, make sure to thoroughly wash them in water for 5 to 10 minutes to remove as much dirt and residue as possible. And be sure to cook them completely! So, these are the three foods you should pay extra attention to, often hidden on supermarket shelves and rarely mentioned. To be honest, every time I go to Costco to buy organic black beans, I've never encountered anyone else rushing to grab them. Hopefully, next time, I’ll see you there, also buying black beans! That’s all for today’s video. Thank you all for watching, and special thanks to the members who have supported me over these past few months. See you in the next episode. Bye-bye!
