To my knowledge, the 'nutrient benefit' of coffee types is rarely in question, as coffee offers little or no seriously beneficial component. The variation in caffeine levels us ultimately the only compositional change that is well-covered; there's no discussion on the vitamin B in store bought versus organic, or the mineral content in Starbucks versus Folgers. Instant coffees and cheap product are often made up of 'canephora', a cheaper and easier to grow coffee.
The end quality and caffeine content of these products is usually lower. "Arabica" beans make up many gourmet and served coffees. These are regarded as more rich, and their products typically bear more caffeiene.
Organically grown, carefully stored coffees made of Arabica beans would typically bear the highest caffeine content. If you consider espresso a form of coffee, even though it's simply a method of brewing, that product contains an even higher concentration of caffeine. Above that would be some hypothetical Cuban frankenstein of mutant espresso.(none of them are nutritious or beneficial.
The enjoyment of these products is a result if them being a social drug of choice. I am addicted to it, of course).
French pressed organic shade-grown freshly ground coffee beans make the most delicious and healthiest coffee.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
