She found it difficult to accept the diagnosis. It was only after discussing her eating habits with her doctor that she realized her diet might have contributed to the illness.
Living alone and working hard in another city, Ms. Fang knew how difficult it was to earn a living. She was very frugal, always trying to use up all her food, even if it had been sitting in the fridge for a long time. Due to her busy work schedule, she often ate leftovers stored in the refrigerator.
However, low temperature ≠ sterilization! While refrigeration slows down food spoilage, it does not completely stop bacterial growth or the formation of harmful substances.
Studies show that 44% of refrigerators have mold contamination issues, with some bacteria exceeding safe levels by up to 750 times. Bacteria like Salmonella and Listeria monocytogenes—so-called "cold-resistant bacteria"—can survive in refrigerators for months. An unclean fridge, especially the crisper drawer, can become a breeding ground for bacteria.
Foods Stored Too Long in the Fridge | Potential "Accomplices" to Cancer
1. Leftover Seafood
Fish, shrimp, and other seafood can produce protein degradation compounds such as ammonia and hydrogen sulfide after being left overnight, which may harm liver and kidney function. Additionally, long-stored seafood increases the risk of Helicobacter pylori (H. pylori) infection—a major factor linked to stomach cancer.
2. Fruits, Vegetables, and Nuts
Leafy greens, one of the most common items in refrigerators, naturally contain nitrates. However, if stored for too long, they may produce nitrites, which can then form nitrosamines, a known carcinogen.
Spinach, in particular, has significantly increased nitrite levels after cooking and refrigeration, sometimes exceeding national safety standards.
Besides leafy greens, staple foods and nuts are also commonly stored in the fridge. If kept for too long, they can absorb moisture and develop mold, leading to the production of aflatoxins—highly toxic carcinogenic substances.
Aflatoxins are far more toxic than cyanide and arsenic. They can damage human DNA and trigger cancerous mutations, significantly increasing cancer risk.
3. Rice, Flour, and Other Starchy Foods
Besides leafy greens, staple foods and nuts are also commonly stored in the fridge. If kept for too long, they can absorb moisture and develop mold, leading to the production of aflatoxins—highly toxic carcinogenic substances.
Aflatoxins are far more toxic than cyanide and arsenic. They can damage human DNA and trigger cancerous mutations, significantly increasing cancer risk.
According to the 2022 Stomach Cancer Diagnosis and Treatment Guidelines, China records 679,000 new stomach cancer cases annually, with most patients already in the middle or late stages when diagnosed, missing the best treatment window.
Dr. Cai Yaoqing, Associate Chief Physician of the First Gastrointestinal Surgery Ward (Minimally Invasive Surgery) at Hainan Cancer Hospital, stated that early-stage stomach cancer symptoms are often atypical. Many people mistake them for benign conditions such as gastritis or gastric ulcers, failing to seek timely medical intervention, which leads to delayed treatment.
How to Tell the Difference Between Stomach Cancer and Common Stomach Problems? Experts warn that five unusual symptoms could signal stomach cancer!!!
1. Changes in Pain Patterns
Gastritis and ulcers usually cause predictable stomach pain. For instance, gastric ulcers typically cause discomfort about an hour after eating. If the pain pattern suddenly changes, it may indicate a malignant transformation.
2. Rapid Weight Loss
Stomach cancer can severely impair nutrient absorption, leading to a sudden and significant drop in weight, often accompanied by loss of appetite, diarrhea, and fatigue.
3. A Hard Lump in the Upper Abdomen
If you feel a firm, painful lump around your upper stomach (near the sternum), it may be a sign of stomach cancer and should not be ignored.
4. Heartburn and Acid Reflux
Heartburn typically occurs just below the breastbone, causing a burning sensation. Acid reflux feels like stomach acids moving back into the mouth, creating strong discomfort. Persistent symptoms may indicate a more serious condition.
5. Black Stools
Unexplained black stools lasting for an extended period may be a sign of ulcer malignancy and should be checked by a doctor as soon as possible.
Preventing Stomach Cancer | Safe Refrigerator Use Tips
1. Keep Your Fridge Clean
Clean your fridge at least once a month. Wipe away food residue and spills immediately.
2. Store Foods Separately to Prevent Cross-Contamination
Keep fruits and vegetables separate from meats to prevent bacterial transfer and unwanted odors.
3. Cook Only What You Need, Reduce Storage Time
The fridge is not a cure-all—try to reduce the amount of stored food and shorten its storage time. Cook only as much as you need to ensure freshness and avoid waste.
4. Don t Wait for Food to Cool Completely Before Refrigerating
If you don t want to waste leftovers, don t wait for them to cool completely before putting them in the fridge. Storing hot food directly can reduce the chance of bacterial growth. When taking leftovers out of the fridge, always reheat them thoroughly before eating.
