For groceries, one meal at a time in the south and a ton at a time in the north
Winter, northerners freeze into dogs in the south
Southerners think the north is really warm
North and South have saucy operations
that each other will never understand
Life differences also hide many health secrets
Today’s Competition
(The last one is too exciting, please pull down to the “seventh round” in a hurry)
Pull down to see Southerners’ counterattack
Competition results: North wins
Heat and dry vs. wet and cold, both north and south are uncomfortable indoors in winter
Tips
Ambient temperature18℃~25℃
RH40%~70%Most comfortable[1]
Winter indoor temperature is best controlled at 20℃~21℃
Too low may induce respiratory and cardiovascular diseases[2]
Too hot, the temperature difference between indoor and outdoor is large, and it is easy to catch cold when going out
Keep humidity at 40%~70%[1]
Too wet will accelerate heat dissipation and make people feel very cold
Too dry, people will feel like they are all dry! Dry! Dry!
Tips
Buy a thermo-hygrometer and keep the pointer in the green area
When the temperature in the northern home is higher than 25℃, you can turn down the heating
Or call the heat company to handle it
The humidity in the south exceeds 70%, and the dehumidification function of the air conditioner can be turned on
Pull down to see Southerners’ counterattack
Competition results: North wins!
Heating is an artifact
Roasted sweet potatoes, roasted insoles, roasted socks, roasted panties
Unexpected, no bake
Note that food and clothing cannot be grilled together
Avoid the embarrassment of insole smelling sweet potato or sweet potato smelling insoles
Tips
Underwear must withstand the baptism of feces and farts
Often carry Escherichia coli, Salmonella, etc.
Put food on the radiator and bacteria have a chance to slip into the digestive tract
You may have diarrhea
Do not bake insoles, socks, and panties together
Shoes are relatively airtight and moist, which is conducive to fungal growth
And the bacteria on the underwear come together with each other
May cause tinea corporis, jock itch, itching all over
Tips
The rainy season in the south, back to the south
Mould infests walls, furniture, clothing, food…
You can add some disinfectant to the laundry, and then dry it before drying
If it’s not dry and musty after 2 days, it needs to be rewashed
If possible, it is best to buy a clothes dryer
No conditions, I can only make do with a hair dryer…
Keep some clothes desiccant in the closet
Scroll down to see what happened to the Southerners
Competition results: Southern wins!
Tips
Storing vegetables at room temperature compared to refrigeration
will produce more nitrite[3]
And the longer the storage time, the higher the content
Nitrite decreases after cooking
But leftover vegetables can be stored at room temperature or refrigerated
Nitrite levels will rise[4]
Long-term, small amount intake may cause cancer! [5]
Tips
Buy and eat vegetables, buy 1~2days‘s amount
at a time
If you can’t finish eating, wrap it in plastic wrap and put it in the refrigerator
As for the behavior of hoarding Chinese cabbage and green onions, it still needs to be changed
After all, it is 2022, so there is no shortage of food and drink!
Competition results: South wins!
Southern exquisite, small dishes and small bowls, with meat and vegetables
Northern boldness, potatoes, beans, ribs in one pot
Stewing is a healthy way to cook
But the portion is so big and the stew is so fragrant, it’s easy to eat
North and South have different definitions of “vegetable”
Overall, the South is better when it comes to nutritional balance
Tips
How to learn from each other’s strengths in the diet of the North and the South[6]?
Daily Salt intake should not exceed 6 grams, cooking oil 25~30 grams
Add no more than 50 grams of added sugar per day
preferably less than 25 grams[6]
It is recommended to eat 250~400 grams of grains, potatoes and mixed beans per day
300~500 grams of fresh vegetables, 200~350 grams of fruits
Fish, poultry, livestock, eggs 120~200 grams
Milk and dairy products 300g, soy nuts 25~35g
Pull down to see Southerner’s explanation
Competition results: Southern wins!
Tips
“Rice” is completely different in the concept of northerners and southerners
Rice is nutritious[7], but not superior to other grains
For example, protein, 100 grams of milled rice contains 7.3 grams
The same weight of oats contains 16.9 grams[6]
Improving the nutritional structure of rice is simple – cook multigrain rice
North’s problem is a staple too! many! !
Rougamo+Saozi Noodles+Lamb Soup
Boiled fire + sesame biscuits
It’s a “carb bomb”
The Lancet-Public Health study points out
Low-carb diet (carbs make up less than 40% of total calories)
and a high-carb diet (carbs make up more than 70% of total calories)
both are associated with an increased risk of premature death
and moderate carb diets
(Carbohydrates account for 50%~55% of total calorie intake)
Lowest risk associated with premature death[8]
Therefore, it is not healthy to abstain from staple foods and eat too much
Tips
How many staple foods are appropriate for each meal?
About 75~160 grams of grains per meal is enough
About 1 fist-sized bun + 1 sweet potato[6]
Results: Tie
Northerners are amazed by the tolerance of bath towels
Southerners’ pursuit of frequency of bathing leaves northerners unmatched
However, always rubbing and washing is not good!
Tips
Old use towel, bath ball, loofah rubbing vigorously
Or washing too often can damage the sebum membrane
Skin can become dry, itchy, sensitive, prone to infection, and allergies[9]
Tips
A shower every 2-3 days is enough[10]
It’s okay to wash every day, it’s just a personal habit
In dry areas and in severe cold seasons
Elderly people with little activity can wash once every 1-2 weeks[10]
The time is controlled at about 10 minutes[10]
Just use a soft towel + shower gel
Households using natural gas, gas
Pay attention to ventilation when bathing and do not wash for too long
Beware of carbon monoxide poisoning
Competition results: both! lose! !
Xiaoqiang is one of the oldest creatures in the world
One small strong can breed thousands of offspring in one year
Some species of females are still alive! sex! complex! Breed!
If you see a little strong at home, congratulations
You have uncovered the tip of the iceberg
There must be nothing under the iceberg! number! only!
Whether it is the agile “little strong” (German cockroach) in the north
Or the “big power” (Periplaneta americana) that can fly in the south
both carry approximately 40 bacteria-causing species
Including Mycobacterium leprae, Yersinia pestis, Shigella, etc.
Can also carry the eggs of viruses, fungi, protozoa and parasitic worms[11]
Xiaoqiang’s feces, eggs and shells can also cause allergies
OMG! The scalp is numb and the back is cold!
Tips
Slippers have a strong “slap” and are a skill that every Cantonese person is born with
But I have to advise you to give up physical attacks!
Female Xiaoqiang has a device called “egg sheath” in her body
Full of eggs
The scabbard is very hard and cannot be damaged by stepping or tapping
Let the “strong egg” stick to the ground and the “drag child” instead
And spreads to every corner as you walk along
To deal with Brother Qiang, chemical weapons are more reliable
Xiaoqiang will not hang up immediately after some cockroach-killing bait is eaten
But after returning to the old nest, slowly poisoned to death
Xiaoqiang has the ability to eat corpses and feces
The toxicity spreads slowly through the family
Check for these active ingredients when purchasing:
Acephate, Phorphos, Chlorpyrifos, Proxacarb
Fipronil, Fipronil, Imidacloprid and Sulfluramid, etc.[12]
Which small and strong medicine should I buy?
Sorry, no ads here!
Write at the back
North and South people have lived like this for thousands of years
No one is healthier
Some of the health problems mentioned above
Just pay attention, Remember to forward it to the family group~
