On such a hot day, watermelon must be eaten to relieve the heat, but did you know that watermelon skin is also a treasure for health preservation. There are also apple peels, corn peels, eggplant peels… well matched, even more nutritious than the food itself!
Don’t waste these skins, they are all “health treasures”
Watermelon rind
The green part of the watermelon rind after removing the outer hard skin is called the watermelon cuiyi.
Compared with watermelon meat, it is low in sugar, low in calories, less burden on the body, and rich in malic acid, lycopene and citrulline, etc., which help to improve immunity, promote metabolism, and protect cardiovascular and cerebrovascular. Eating it in summer also has the functions of dispelling summer heat and producing body fluid, quenching thirst, diuretic, and removing dampness.
There are many ways to eat watermelon rind. It can be stir-fried, stewed with white fungus in sweet soup, or eaten cold.
To tell you the truth, this is the first time Xiao Er eats boiled watermelon. The taste is salty and fresh. The shrimp balls also have the fruity aroma of watermelon.
Watermelon promotes body fluids, white fungus skin cares and moisturises the lungs, and is decorated with fresh longan and wolfberry, which is pleasing to the eye. These two creative watermelon dishes are cool and refreshing, cool off the heat, very suitable for hot summer~
apple peel
Half of the dietary fiber in apples is in the peel. Not only that, the content of nutrients such as chromium and zinc in apple peel is also much higher than that of pulp. It also contains a lot of polyphenols and flavonoids, which are very beneficial for the prevention of chronic diseases such as coronary heart disease and hypertension.
Therefore, it is better to eat apples with the skin on.
Tips
Some friends may be worried that the apples are waxed so they are afraid to eat the peels. But usually, the wax on the peel is the natural fruit wax produced by itself or the edible wax that meets the “Hygienic Standard for the Use of Food Additives”, soaked in water, and then washed with running water, which can basically be removed.
If you are worried about pesticide residues, you can put a small amount of baking soda in the water, then put the vegetables and fruits in it for 5 to 10 minutes, and then rinse with running water. Baking soda is an alkaline substance, while pesticides are mostly acidic, and the two can undergo a neutralization reaction, thereby promoting the rapid decomposition of pesticide residues.
eggplant skin
Most of the anthocyanins in eggplant are concentrated in the eggplant skin. In addition, eggplant skin is rich in vitamin E, which can resist oxidation. It contains more iron than eggplant meat and has high nutritional value.
In terms of eating methods, in addition to serving with eggplant meat, eggplant skin can actually be eaten as a separate ingredient.
Corn husks
Summer corn is very fresh and tender. As a “golden staple”, it is full of treasures. The corn kernels can be eaten, and the corn husks can be used as containers.
Similar to corn silk, corn husks have the effect of diuretic, drenching, and swelling. It is good to soak in water instead of tea in summer.
Corn husks instead of tea
Ingredients: corn silk, corn husk, ginger shreds
Methods: Remove the outer green husk of the corn, keep the light yellow outer skin of the inner layer, cut off the rotten whiskers on the top, keep the fresh and tender corn silk, and make tea with shredded ginger.
Ginger shreds are pungent and warm to dispel cold, warm the stomach, and the corn silk is sweet, diuretic and swelling, and the corn husk is fragrant.
It is better not to eat these two kinds of skins
Sweet potato peel
Nutritionally speaking, sweet potato peel is not bad, but it contains alkaloids, which may cause dizziness, diarrhea and other adverse reactions after eating a lot.
Especially sweet potato skins infected with black spot bacteria and with brown or dark brown spots on the skin are not suitable for consumption, because the toxins discharged by black spot bacteria contain sweet potato ketone alcohol, which cannot be eaten after cooking or grilling. After being killed, it will cause great damage to the liver after entering the human body.
Potato peels
Everyone knows that potatoes will produce a large amount of toxic substance solanine after germination, so they should not be eaten. In fact, this toxin is also contained in unsprouted potatoes, but the content is extremely low, generally within 90-400 mg per kilogram.
However, 30% to 80% of the solanine in potatoes is concentrated on the outer skin. Although eating normal potatoes with the skin on will not pose a threat to health, from the perspective of minimizing the intake of solanine, it is recommended that you peel off the skin, which is safer and has a better taste.
