Super comparison, coffee, milk, tea, which of the three major beverages is the most beneficial to health
Three national beverages: milk, coffee, and tea have great health functions
To compare the pros and cons of these three commonly used beverages, it is necessary to set up several specific comparison indicators for joint inspection.
1. Nutritional ingredients:
Milk: The protein content in fresh milk is above 3% on average, mainly including casein, lactalbumin, lactoglobulin, etc., which are all good-quality proteins. The protein digestibility of cow's milk is 90-100%, and the utilization rate can reach 75- 100%, and the biological value (the percentage of egg whites retained in the body after being absorbed) is as high as 85%, which is only lower than that of eggs. Milk fat is rich in fat-soluble vitamins and free fatty acids, rich in lecithin, cephalin and neurophospholipids, which are essential components for the maintenance of human brain nerves and other cell structures. However, the most important thing is the calcium in milk, which is an important source of promoting the growth of human bones.
Coffee: Let’s talk about the nutritional components of coffee first. The nutritional value of the components in coffee includes fat (acidic fat and volatile fat) and protein. It is not easy to dissolve and difficult to ingest. In addition, the content of minerals such as iron, phosphorus, and sodium carbonate in coffee is also very small.
Tea: Finally, let’s look at the nutrients in tea. Tea contains vitamins A, D, E, K, B1, B2, B3, B5, B6, H, C, P, etc. The vitamin C content is relatively high and average The content of green tea per 100 grams is about 100 to 250 mg. In addition, tea also contains water-soluble protein and 25 kinds of amino acids needed by the human body. In addition, there are a variety of trace elements. Among them, the zinc content is higher, with an average zinc content of 73 micrograms per gram of green bars.
In terms of nutrient content, cow's milk has the best content, which is better than coffee and tea.
2. Antioxidant function:
Milk: The vitamin A in milk can prevent night blindness and has antioxidant properties. A research team from the University of Kansas Medical Center in the United States conducted a study and found that elderly people who drink milk have more glutathione in their brains, and glutathione is a kind of glutathione that exists in the brain. Natural powerful antioxidants can help reduce the oxidative stress of the brain and the damage caused by reactive chemical compounds in the metabolic process. It is inferred that milk may also have antioxidant functions for the brain, and has the effect of reducing the incidence of neurodegenerative diseases, such as dementia.
Coffee: Among all foods, coffee has the most content of chlorogenic acid. Chlorogenic acid has an anti-oxidant effect to reduce the damage of cells by free radicals. Therefore, it is considered to be related to the prevention of chronic diseases or cancer. In addition, coffee contains a large amount of caffeine. Research results published by a research team at a university in Mexico show that caffeine is the main source of antioxidants in coffee ingredients. , Free radicals related to heart disease, and then destroy it. Good for human health.
Tea: As for tea, there are polyphenol antioxidants. Polyphenol antioxidants can effectively scavenge free radicals and inhibit oxidation. A cup of freshly brewed raw leaf tea, about two grams of tea, contains more than 200 milligrams of polyphenols. Antioxidant is considered to be the antioxidant with the highest CP value. In addition, the catechins in green tea can effectively expand blood vessels, accelerate blood circulation, and also have antioxidant functions.
In terms of antioxidant function, coffee and tea perform slightly better than milk.
3. Refreshing effect:
Milk: Clinical experiments have confirmed that drinking more milk can be refreshing, because the amino acids that constitute milk protein in milk can stimulate hypothalamic cells to produce orexin, and orexin is a hormone produced by hypothalamic cells. Only if orexin is sufficient, it is not easy for talents. Lethargy. Studies have also shown that the sugar in milk can concentrate people's attention and moderately boost their spirits.
Coffee: Most people think that the main function of coffee is refreshing. A cup of coffee contains about 75 to 150 mg of caffeine, which can achieve refreshing effect in a short time. However, coffee is not only diuretic, but also inhibits the absorption of body water. The iron is quickly lost, and it takes a long time, resulting in energy consumption. Although it can boost energy in a short time after ingesting coffee, it has a refreshing effect, but it also fades quickly, and many people will feel more tired within a few hours.
Tea: As for the catechins in tea, they can effectively dilate blood vessels, accelerate blood circulation, clear brain thoughts, and activate the brain's memory and cognitive abilities more than coffee. In addition, catechins can slow down the decomposition of dopamine and adrenaline in the brain, which makes people refresh and wake up quickly. Because the content of caffeine in tea soup is much less than that of coffee, it is harmful to the stomach and nerves. The side effects of irritation are also relatively small.
In terms of refreshing effect, coffee and tea have similar effects, and both are better than milk, but coffee can only refresh people quickly in a short period of time, while tea has less side effects than coffee in addition to refreshing.
No matter how much you like to drink these 3 kinds of drinks, they should not completely replace drinking water.
After comparing the benefits of milk, coffee and tea on human health, no matter which of these three beverages, although they can be calculated in the daily water intake, they cannot completely replace the importance of water for human health. Status, I hope everyone still needs to drink enough water, at least 1500cc a day.
