In our daily lives, there are all kinds of gossip about food, especially about seafood. For example, you may have heard that "the whiter the skin of the hairtail, the higher the nutritional value", or that "eating fish eyes regularly will make your eyes clearer". These statements sound plausible, and even seem to be the inheritance of ancient wisdom. But are these widely circulated claims really scientific? For those of us who care about healthy eating, it's important to distinguish between authentic and fake food messages.
As one of the common seafood, hairtail is widely loved, especially its skin, which has attracted attention for its unique taste and nutritional value. There is a saying in the market: "The whiter the skin of the hairtail,."The higher the nutritional value. But in reality, there is no scientific basis for this claim.
First of all, the color change of the skin of the fish is mainly affected by its living environment and feeding conditions. In the natural environment, the skin color of hairtail fish may vary depending on the water in which they live. The skin color of farmed hairtail fish may be affected by feed and farming techniques. Therefore, the color of the skin is not a direct criterion for judging its nutritional value.
Secondly, the nutritional value of hairtail mainly comes from its rich protein, unsaturated fatty acids (such as omega-3 fatty acids), and various vitamins and minerals. These nutrients are especially important for middle-aged and older adults, which helps maintain heart health, lower blood lipids, improve brain function, and more. These nutrients have nothing to do with the color of the skin.
In addition, when buying hairtail, you should pay attention to its freshness rather than just the skin color. Fresh hairtail with firm flesh and clear eyes and no peculiar smell. These characteristics are more reflective of the freshness and edible value of the hairtail than the skin color.
Finally, for middle-aged and elderly people, a reasonable diet is more important. The nutritional value of food should not be judged solely by its appearance, but should also be taken into account its nutritional content, freshness and personal health.
In our daily life, we often hear a saying: "Eating fish eyes can brighten the eyes." This traditional notion stems from the traditional understanding of the function of food, but it should be revisited in the light of modern medical research.
Nutrient composition analysis in the eyes of fish.
First, let's take a look at the main ingredients of fisheye. Fisheye contains a certain amount of protein, fat and trace elements, among which DHA (a polyunsaturated fatty acid) and vitamin A are of particular concern. DHA plays an important role in the brain and retina, while vitamin A is an essential nutrient for maintaining normal vision and eye health.
The truth from the perspective of modern medicine
However, modern medical research has shown that while fish eyes contain nutrients that are beneficial to the eyes, they are relatively low in amount and are not the only or optimal**. For example, DHA and vitamin A are found in higher levels in fish and other foods such as green leafy vegetables and carrots, which are more easily absorbed and utilized by the body.
Healthy Diet Recommendations
Therefore, if we want to protect our eye health, we don't have to rely too much on eating fish eyes. It is advisable to eat a balanced diet with plenty of foods rich in DHA and vitamin A. In addition, it is equally important to have regular eye exams and maintain good eye habits.
Nutritional value analysis
Next, let's ** the nutritional value of fish. Fish is an important protein for good quality and is rich in unsaturated fatty acids, especially -3 fatty acids (such as EPA and DHA). These fatty acids are extremely beneficial for heart health and may reduce the risk of cardiovascular disease.
Special benefits for middle-aged and older people
For middle-aged and elderly people, fish not only contributes to heart health, but also improves arthritis symptoms and cognitive function. The high-quality protein in fish is equally important for maintaining muscle strength and function, which is especially critical for age-induced muscle loss.
Suggested way to consume
In order to maximize the nutritional value of the fish, it is recommended to minimize the use of oil when choosing a cooking methodsuch as steaming, boiling, or baking. At the same time, attention should be paid to the ** and type of fish, and try to choose wild fish to avoid the risk of heavy metals and pollutants.
