"Is Leftover Pizza Safe to Eat the Next Day?"... Even Scholars Puzzled by Surprising Results Stir Debate

A microbiologist in the United States has sparked curiosity among internet users by releasing a video in which he personally experiments to see how bacteria multiply on leftover pizza. While the intention was to show how microorganisms increase on everyday foods, some unexpected results led to considerable debate online. According to reports from the UK’s Daily Mail and others, Nicholas Eicher, a microbiologist conducting research in Chicago, conducted an experiment comparing the degree of bacterial growth by sampling slices of takeout pizza immediately after purchase and again after one day. He released a video of this process on his social media account. In the video, Eicher is seen swabbing samples from freshly delivered cheese and pepperoni pizzas, transferring them to petri dishes, and then repeating the same procedure with slices left at room temperature for a day. He then cultured the samples to observe bacterial growth. The results of the cultures both aligned with and contradi

Frequent Consumption Raises Cancer Risk... The Refrigerator Food You Should Stop Eating Now

A domestic study has found that women who frequently consume processed meat have a significantly higher risk of developing breast cancer. In contrast, the study also revealed the intriguing finding that beef consumption may lower the risk of breast cancer.Breast cancer, the most common cancer among women in Korea, sees nearly 30,000 new diagnoses each year. Experts cite Westernized dietary habits, alcohol consumption, smoking, lack of exercise, obesity, and genetic factors as causes of breast cancer. Recently, a research team led by Professors Kang Daehee and Lee Hyobin from the Department of Preventive Medicine at Seoul National University, Professor Han Wonsik from the Department of Breast Surgery, and Professor Lee Jungeun from the Department of Food and Nutrition analyzed the correlation between processed meat consumption and breast cancer incidence using the urban-based cohort study (HEXA study).

Don't Just Blame Genetics... Foods That Can Cause Hair Loss Revealed

Experts have advised that dietary management is key to preventing hair loss.

Dermatologist Dr. Elly Rashid explained, "Diet can either accelerate or alleviate hair loss," adding, "If the nutrients required for hair production and maintenance are lacking, hair can become weaker or fall out more quickly." Key nutrients for hair health include iron, zinc, vitamin D, and folic acid. Dr. Rashid advised, "It is important to check the levels of these nutrients through regular blood tests and maintain a balanced diet." Iron can be obtained from red meat and g

"After Eating Freshwater Snails"...Rare Parasitic Infection Reappears in South Korea After 10 Years

Experts are urging heightened caution to prevent parasitic infections after a rare case was recently confirmed in South Korea. This case, discovered during a routine endoscopic health check, marks the first report of this rare fluke infection in the country in a decade. The Medichek Research Institute of the Korea Association of Health Promotion announced on the 11th that four adult parasites were found during a colonoscopy in a woman in her 60s. The patient, who had long suffered from indigestion, constipation, and intermittent diarrhea, visited an internal medicine clinic, where flukes were detected in the terminal ileum and colon during the examination. Genetic analysis and morphological review identified the parasite as Echinostoma cinetorchis, a species rarely reported in South Korea, with the last known domestic case occurring in 2014. Notably, while most flukes typically inhabit the small intestine, adult flukes were also detected in the colon in this case. This finding was pub

A new study has found that intermittent fasting, a popular weight loss method, may increase the risk of death from cardiovascular disease. On August 31 (local time), the BBC in the United Kingdom reported findings from a team of researchers at Shanghai Jiao Tong University School of Medicine in China and Northwestern University's Feinberg School of Medicine in the United States. The researchers tracked and analyzed the eating habits and health data of about 19,000 American adults over eight years.

[Kim Jaeho's Life Story] <271> Protecting Knee Cartilage Health

Diseases affecting the knee joint are not life-threatening, but they can significantly reduce quality of life due to the various inconveniences experienced in daily activities. The number of people receiving treatment for various knee joint diseases has steadily increased from 2.72 million in 2016 to 3.31 million in 2024, which is only slightly less than the 3.96 million patients treated for diabetes. Knee joint diseases include knee osteoarthritis, which involves inflammation and pain as the cartilage in the knee joint wears away; chondromalacia patellae, where the cartilage in the knee joint weakens or becomes damaged; and patellar tendinitis, which is inflammation of the patellar tendon that connects the kneecap (patella) to the shinbone (tibia). Among these, knee osteoarthritis is the most common, so this article will mainly focus on it. The knee joint is where the femur (thigh bone) above the knee, the tibia (shinbone) below the knee, and the patella (kneecap) in front of the knee
