1. Toxic: Blueberry stone contains copper ions, and excessive intake of copper ions will have a negative impact on human health. Excessive accumulation of copper in the body may lead to digestive symptoms such as poisoning, nausea, vomiting, diarrhea, abdominal pain, and even damage to organs such as liver and kidney.
2. Carcinogenicity: Copper cuprate in blueberry stone is considered to be carcinogenic. Long-term exposure to copper cuprate may increase the risk of cancer, especially malignant tumors such as liver cancer and lung cancer.
3. Food safety: Blueberry kernels are usually not used as food additives, but are used for industrial purposes, such as dyes and wood preservatives. Therefore, the existence of blueberry stone may mean that food or drink is polluted and may contain other harmful substances.
It should be noted that although blueberry stone is harmful to human body, it may be specially treated and controlled in some specific circumstances, such as medical or industrial applications. But for ordinary people, we should try to avoid contacting blueberry stones or eating foods that may contain blueberry stones. Ensuring the safety and quality of food is very important to protect our health.
