Health experts warn of colorectal cancer risks from improper food storage
Medical experts and international health organizations are highlighting the risks associated with dietary habits and food storage. According to the International Agency for Research on Cancer (IARC), colorectal cancer is the third most common malignancy worldwide, with over 1.9 million new cases and 900,000 deaths annually. In Vietnam, Globocan reports approximately 16,835 new cases each year, noting a trend toward younger patients.
Zhu Xishan, head of Oncology at Peking University First Hospital, warns that refrigerators do not eliminate chemical toxins. Specifically, processed meats like ham and sausages stored for more than three days can see nitrite levels rise to unsafe amounts. These nitrites can combine with proteins to form nitrosamines, which are classified by the WHO as top-tier carcinogens that damage DNA in the intestinal lining. Additionally, starchy leftovers can develop denatured toxins over time.
To support health during seasonal transitions, nutritional advice suggests incorporating warming foods such as chicken and seasonal items like pork liver to regulate blood circulation and support liver health.
