[Financial News] Singer Jang Yoon-jeong has shared her usual eating habits, along with her experience trying a once-popular method said to block blood sugar spikes.
On the 11th, a video titled "We came here not to get hate comments... No sugar, no additives, no hate comments, let's go negotiate snacks" was uploaded to the YouTube channel Dalla Studio.
In the video, Jang responded to a question about whether she usually eats snacks by saying, "I don't eat them. I hardly eat meals either."
When asked what snacks her children like, she said, "They like chips, but I try to get them to eat healthy snacks."
Jang also talked about her experience eating peanut butter, saying, "It was trendy for a while. I heard that if you spread peanut butter on an apple and eat it on an empty stomach, it helps prevent blood sugar spikes. So I just ate it."
A blood sugar spike refers to a phenomenon in which blood glucose rises sharply after a meal and then drops relatively quickly. When blood sugar rises rapidly, the body increases insulin secretion to regulate it, and the quick drop that follows can cause fatigue and reduced concentration. If this process repeats, insulin resistance can develop. It can also make body fat easier to accumulate and may increase the risk of obesity, diabetes mellitus, and CVD, so caution is needed.
According to Health Chosun, the apple and peanut butter combination mentioned by Jang is considered one of the representative breakfast pairings that can help manage blood sugar.
The dietary fiber and pectin in apples slow the digestion and absorption of carbohydrates, while the protein and unsaturated fats in peanut butter help slow gastric emptying and reduce the rise in blood sugar after meals. As a result, eating apples and peanut butter together can ease sharp post-meal blood sugar spikes and increase satiety, which may also help control appetite.
