Nowadays, there are many people who love beauty, and there are also many people who pursue good health. Additionally, due to the fact that many people work overtime and sit for long periods, it is easier to accumulate excess fat around the abdomen. Some people with experience in weight loss choose to replace staple foods with other foods to reduce calorie intake and achieve weight loss effects without feeling hungry. Many people choose to replace staple foods with sweet potatoes because sweet potatoes are not only filling but also have a laxative effect. Some even believe that the effect of purple sweet potatoes is better than that of sweet potatoes. At this point, some people may be undecided about whether to choose sweet potatoes or purple sweet potatoes. By reading the following analysis, you will understand.
First, let’s talk about sweet potatoes. Sweet potatoes are very nutritious, containing vitamin C, dietary fiber, and a large amount of carotene, all of which are greatly beneficial to the body. Sweet potatoes are known to have a laxative effect, and people with constipation may choose to eat some sweet potatoes to relieve their condition. Purple sweet potatoes are equally nutritious but do not contain carotene; instead, they contain abundant anthocyanins. Anthocyanins can effectively enhance the body’s resistance. They are found in fruits with darker colors such as grapes, mulberries, blueberries, and have excellent antioxidant properties, which are beneficial for beauty and skin care.
Secondly, under equal quality conditions, purple sweet potatoes have lower sugar and starch content than sweet potatoes, meaning that when replacing staple foods to create a weight-loss diet, purple sweet potatoes have an advantage over sweet potatoes. This implies that purple sweet potatoes are better for weight loss than sweet potatoes.
However, this does not mean that sweet potatoes are not good. Compared to purple sweet potatoes, sweet potatoes have a softer texture, and they have higher starch and sugar content, making them more popular among the general population. If you do not have hypertension, hyperglycemia, hyperlipidemia, or do not specifically aim for weight loss, eating sweet potatoes is still beneficial, as they can also help relieve constipation. In terms of price, sweet potatoes are relatively cheaper.
Lastly, it is important to note that although purple sweet potatoes are low in sugar and starch and are suitable for weight loss, if they are prepared in a method such as candied or deep-fried, it will only add to their calorie content. Therefore, the cooking method is crucial for weight loss. For those who pursue taste, purple sweet potatoes can be made into mashed salad. Peel and cut 1–2 purple sweet potatoes into pieces, boil them until a chopstick can easily pierce through, drain them, and mash them in a bowl.
You can add yogurt, vegetables, or fruits according to your preference, making it tasty, healthy, and low in calories. If you are not inclined toward these options, simply steam the purple sweet potatoes and eat them after peeling; this is the most convenient and effective method. Of course, purple sweet potatoes must be fully cooked before consumption; uncooked purple sweet potatoes contain starch that is difficult to digest, increasing the digestive burden on the stomach and intestines.
