Lectins are a type of protien found in many of the foods you mentioned.
Some people can have allergies to lectins which of course can be dangerous.
Additionally there are certain types of lectins (such as those found in Castor Beans) that are highly toxic and can cause illness or even a quick death.

In 1988 a hospital launched a "healthy eating day" in its staff canteen at lunchtime. One dish contained red kidney beans, and 31 portions were served. At 3 pm one of the customers, a surgical registrar, vomited in theatre. Over the next four hours 10 more customers suffered profuse vomiting, some with diarrhoea. All had recovered by next day. No pathogens were isolated from the food, but the beans contained an abnormally high concentration of the lectin phytohaemagglutinin.1 Lectins are carbohydrate binding proteins present in most plants, especially seeds and tubers like cereals, potatoes, and beans. Until recently their main use was as histology and blood transfusion reagents, but in the past two decades we have realised that many lectins are (a) toxic, inflammatory, or both; (b) resistant to cooking and digestive enzymes; and (c) present in much of our food. It is thus no surprise that they sometimes cause "food poisoning." But the really disturbing finding came with the discovery in 1989 that some food lectins get past the gut wall and deposit themselves in distant organs. So do they cause real life diseases?

Commonly found in grains, milk, beans and other assorted foodstuffs, they are benign if prepared correctly but...
Think of a lectin as a protein containing a key that fits a certain type of lock. This lock is a specific type of carbohydrate. All life forms, plant and animal, insect and fungus have cell membranes that contain carbohydrates that sit within and project from the membrane. If a lectin with the right key comes in contact with one of these 'locks' on the gut wall or artery or gland or organ it 'opens the lock', that is disrupts the membrane and damages the cell and may initiate a cascade of immune and autoimmune events leading to cell death.
In other words, they are toxic.

They are naturally occurring substances usually proteins derived from plants which act like anti bodies but are not formed in response to an antigen
