Toxins are often imagined as rare substances found only in polluted rivers, industrial waste sites, or chemical laboratories. In reality, they are woven quietly into everyday life. They enter the body through the air we breathe in traffic, the packaging that touches our food, the drinks we rely on for energy, and the meals we consume without much thought. The modern environment exposes the human body to a constant background of chemical stress, not through dramatic single events, but through small, repeated choices made day after day.

Travel often makes people more alert to danger. You check neighborhoods, avoid risky situations, and take recommended vaccines before stepping on a plane. Most travelers believe they’ve covered all the obvious threats. What often goes unnoticed is something far more ordinary and far more intimate: food. What ends up on your plate can sometimes pose risks that are just as serious as environmental hazards or infectious diseases

Natural toxins are poisonous chemical compounds that are produced naturally by living organisms. These substances serve important biological purposes for the organisms that make them, such as defense against predators, insects, or competing microorganisms. While harmless to the plants, fungi, algae, or animals that produce them, these toxins can become dangerous when consumed by humans or livestock. Their chemical structures vary widely, and so do their biological effects, ranging from mild irritation to severe poisoning
