Plant foods contain defense chemicals such as oxalates, phytates, saponins, lectins, isothiocyanates, polyphenols, salicylates, and phytosterols.

“there certainly is evidence that all of these types of compounds polyphenols lectins oxalates isothiocyanates which are Brassica vegetables and other compounds of plants may be toxic to humans”

“i talk about oxalates and lectins and salicylates and i talk about all kinds of things like that that are harming us isothiocyanates which i will talk about today which are things like sulforaphane and goitrin and how these plant compounds can affect hormonal balance they can affect nutrient absorption they can affect our gut and really wreak havoc in a lot of us if we are not aware of how present in our diet they are how we might detoxify them and how some of us might be more specifically sensitive to them than others and they can be causing us great harm and suffering”

“I think there are some plant compounds that at least for some people are not so good and you know there are well characterized examples of this like if you eat a lot of spinach you can get kidney stones from all the oxalate — there are studies suggesting that the glucosinolates in cabbage family plants might contribute to type 2 diabetes”
