Why is food addictive?
As for "why junk food is addictive", sweets have been widely studied at home and abroad.
If you feel satisfied when eating carbohydrates such as desserts, biscuits and sweets, but feel uneasy and anxious when eating a low-carbohydrate diet, then you may be addicted to sweets.
Carbohydrate addiction may be more appropriate than addiction.
The influence of food on mood is related to these factors.
Dopamine brings pleasure.
High-sugar food can stimulate the brain to release dopamine, which makes people feel happy.
Increased blood sugar brings satisfaction.
When the blood sugar level of human body is relatively high, the mood is relatively stable and happy; When the blood sugar level is low, it is easier to be irritable, irritable and depressed.
Starch, sugar and other carbohydrates can quickly increase blood sugar after entering the human body, which makes people feel psychologically happy and satisfied.
The "Reward Path" is activated.
Delicious food can activate the midbrain-limbic dopamine nervous system that regulates emotions, promote the release of dopamine, make people feel euphoric and enhance related behaviors. This is the so-called "reward pathway" 1.
Other viewpoints
At present, some scholars do not support the view of "food addiction". They believe that many defining characteristics of drug addiction do not appear in dietary behavior. Whether food will be "addictive" is still unclear.
Who's messing with your "glutton"?
Sweet food is a broad concept, which can make people feel longing and other emotions, mainly including these two foods.
High sugar food
Sugar here actually refers to carbohydrates, including glucose, maltose, sucrose, starch and other substances that provide heat for the human body.
High GI food
The glycemic index (GI) of food refers to the relative speed at which carbohydrates in a certain food can increase blood sugar within two hours after entering the human body.
70% of GI> is a high GI food. This kind of food raises blood sugar faster, but the pleasure often comes and goes quickly. When the blood sugar level drops, this pleasure will disappear, and you will feel hungry and eager.
So exquisite foods such as desserts and white bread will make people want to eat more and more.
Low-carbohydrate foods, such as miscellaneous grains, raise blood sugar slowly, but can last for a long time, which will make the mood more stable.
Sweets make you happy and hurt you.
While sweet food brings pleasure, it will also "give away" a lot of calories, and finally let the body pay the bill.
fat
If you eat too much sweets, the calories that your body can't consume will eventually become fat and be stored.
acne
Eating too many sweets can also trigger the body's inflammatory reaction and cause skin problems such as acne.
guilty
After overeating, due to the increase of guilt, it is easy to feel depressed and unstable, which is not conducive to mental health.
chronic ailment
Long-term intake of excessive calories will also increase the risk of chronic diseases such as cardiovascular disease.
How to get rid of the "domination" of sweets?
It doesn't hurt to eat sweets once in a while, but if you are stubborn, you might as well quit.
Eat three meals.
Eating three meals a day on time can reduce the desire for sweets.
When people are hungry, they often want to eat high-sugar and high-calorie foods such as cakes and chocolates, and it is more difficult to resist the temptation of sugar.
When eating, you may wish to increase foods that can enhance satiety, such as vegetables and miscellaneous grains.
Vegetables are more than staple food, so you can eat three dishes and one meal when you eat; Replace some staple foods with miscellaneous grains, such as eating less than half a bowl of white rice and replacing it with the same amount of oat rice.
Take enough protein.
Be picky about food.
Eating dessert occasionally has little effect on health. Instead of eating low-end desserts often, it is better to save money to buy a high-end dessert. I believe you can keep your mouth shut under "economic constraints".
Brain hole said:
Many studies show that people prefer to eat sweets when they are stressed or depressed.
In fact, sports, parties, shopping and other ways can also drive away unhappiness. Long-term exercise can also increase the production and reserve of dopamine, and make people feel a sense of accomplishment and happiness, which is more effective than eating sweets.
