Exercising caution when it comes to food safety and being selective about the sources of your food is generally not considered paranoid behavior. It is entirely reasonable to be conscious of food safety and to prefer consuming food prepared by individuals you know well or from reputable establishments.
Foodborne illnesses are a real concern, and many people take precautions to minimize their risk of getting sick. Ensuring that food is prepared and handled properly is essential to prevent contamination and food poisoning. Common precautions include checking food expiration dates, observing proper hygiene during food preparation, and making sure food is cooked to appropriate temperatures.
When people are cautious about food safety and prefer eating food from sources they trust, it shows they are being responsible and looking out for their well-being. This behavior is a normal and healthy response to the potential risks associated with consuming food that may not be adequately prepared or stored.
However, it is essential to strike a balance between being cautious and becoming overly anxious or excessively restrictive about food. If these concerns about food safety start significantly impacting one's daily life, become distressing, or lead to social isolation or malnutrition, it might be helpful to talk to a healthcare professional to address any underlying anxiety or obsessive-compulsive tendencies that could be contributing to these concerns.
