The secret to staying slim in your 50s... Shin Ae-ra goes crazy over 'this😱😱' while eating rice

Actress Shin Ae-ra (55) revealed that chewing food until it turns into water and swallowing it is her secret to maintaining her figure without gaining weight.

 

On the 18th, the YouTube channel 'A-grade Jang Youngran' posted a video titled 'Jang Youngran's Respectful Sister Shin Ae-ra's "How to Captivate Your Husband" (Cha In-pyo)'. Jang Youngran asked Shin Ae-ra questions and inquired, "Many people are curious about your body secret." It is known that Shin Ae-ra maintains a weight of less than 50kg. Shin Ae-ra said, "Once you pass 50, the secret is just eating less," and "Exercise alone definitely doesn't work." She added, "I love eating too much," and "When I tried to cut back, I wanted to eat so much that I couldn't find a way." She then revealed her method, saying, "The way I found is to chew like crazy," and explained, "If you don't chew for long and just swallow quickly, you'll want to eat more, so when I eat one piece, I put down the chopsticks and keep chewing until the water comes out." What are the actual health benefits of the habit of thoroughly chewing food like Shin Ae-ra?

 

First, chewing food for a long time can prevent overeating and help with weight management. The longer you chew, the more saliva is secreted, which contains the enzyme amylase. Amylase is a carbohydrate-digesting enzyme that quickly breaks down starch into sugars. When blood sugar levels reach a certain point, signals are sent to the brain's satiety center (the center that suppresses appetite or thirst when needs are satisfied), indicating fullness. Chewing food thoroughly increases enzyme secretion in the mouth and raises blood sugar levels. Because blood sugar levels rise quickly, you can feel full sooner, preventing overeating. Conversely, if you chew less, enzyme secretion decreases, signals to the brain are delayed, and the feeling of hunger persists longer.

 

It is advisable to take about 20 minutes to eat a meal. When we eat, our body secretes the hormone 'leptin' to induce a feeling of fullness. However, since it takes about 20 minutes for leptin to be secreted, eating quickly before that can lead to overeating without any control, resulting in weight gain. Eating slowly and chewing thoroughly can also trigger 'DIT (Diet Induced Thermogenesis)', which is the increase in energy expenditure after a meal. DIT refers to the phenomenon where the body's energy metabolism increases even when at rest after eating. Generally, about 10-15% of the energy consumed during a meal is used for DIT.

 

Eating slowly and chewing thoroughly also helps with digestion. Salivary amylase is a mildly alkaline enzyme that helps maintain the appropriate acidity level in the stomach and duodenum. Therefore, it is effective in suppressing the impact of highly acidic gastric acid secreted in the stomach from causing esophagitis, ulcers, or gastritis in the esophagus or duodenum.

 

Chewing thoroughly also helps prevent dry mouth. This is because saliva washes away food debris and bacteria, keeping the mouth clean. The main cause of bad breath is dry mouth. When the mouth is dry, bad breath worsens in the morning and evening, and cavities and gum diseases are more likely to develop. Normally, saliva is secreted at a rate of 0.25 to 0.35 milliliters per minute, but when chewing food for a long time, saliva production increases and can reach up to 4 milliliters per minute.

 

Chewing habits are also good for preventing dementia. Chewing thoroughly involves the 'masticatory exercise,' which moves the jaw muscles. Masticatory exercise not only moves the jaw muscles but also helps oxygen enter the body, increasing blood flow to the brain. This can supply the brain with a lot of oxygen, potentially improving memory and concentration. In fact, a research team at Cardiff University in the UK conducted a study to understand the effect of masticatory exercise on memory by having one group chew gum and another group not to do so, then calling out numbers from 1 to 9 for 30 minutes and asking them to remember. As a result, the group chewing gum remembered the numbers faster and more accurately.

Chewing slowly and thoroughly has various benefits.

It's good, but it requires enduring effort until it becomes a habit.

I feel like I need it and that it's a battle with myself.

I have given up before~~ but this time, let's do it together.

How about giving it a try?

Let's try to endure by chewing thoroughly for just 20 minutes🤭🤭
