While we eat certain food daily, when not cooked or eaten right or in the right amounts, it can be poisonous and even be fatal. Some typical food that also acts as slow poison are:
Mushrooms: Mushrooms are famously used for a lot of cuisines; it is also extensively used to prepare sauces, as sides, and is fundamentally a highly helpful ingredient; nonetheless, author Gerald O Malley claims that Amanita mushrooms can cause food poisoning, particularly six to twelve hours after indigestion.
Nutmegs: Nutmegs contain myristicin, an active chemical that, when broken down in the body, may cause harm to the neurological system and, in turn, symptoms including headaches, nausea, and dizziness. Studies reveal that after consuming ten grams of nutmeg, significant effects typically manifest within 1.5 hours.
Kidney Beans: The Centre for Food Safety reports that while evenly cooked beans are lectin-free, undercooked beans increase lectin by five times and can cause severe symptoms, including diarrhea and abdominal pain. Eating raw or undercooked red kidney beans, a famously popular ingredient in curries, sides, and chillies, can be fatal.
Brown Rice: Although brown rice has been touted as a weight-loss boon, it should be washed four to eight times and soaked for up to forty minutes before it is safe to eat, as it contains a higher concentration of inorganic arsenic (a toxic compound) than white rice.
Tomatoes: According to author Sienna Livermore, the common red, delicious fruit leaves contain a poison called Glycoalkaloid that can cause stomach trouble, cramps and anxiety.
Peanuts: Despite its popularity, peanuts are notorious for triggering severe allergic reactions in some people. This is because peanuts contain proteins that can bind to and release the body's histamine, which can cause airway obstruction, shock, loss of consciousness, and even death in those sensitive to it. Be wary of this nut and its more favoured version, peanut butter, unless you know you don't have an allergy to them.
So, while all on the list are foods that we may eat regularly, eat “carelessly” or in a different form steeped in unawareness, it can cause severe health damage.
