ive seen alot of shows where they xray the stroke victim and most of the time a section of there cappilaries are unstimulated or inactive, in theory this can be do to lack of nutrition to stimulate the pathways and lack of exercise
this is why dieting is terrible, you are limiting variety and amount of nutrients, also you will be less active from the calories
ALSO you never know if your genes are less likely to indulge in a vitamin that you are consuming you might have low receptors so you need to eat even more to provent stroke and stimulate cappilary growth as well as stimulation of blood flow
ill tell you what drinking frozen grapejuice is the most refreshing thing let it freeze in the freezer all day at work then let it thaw out when you get home while preparing your meal , as its semi frozen shake it up and drink like a slushy damn its the best thing ever way better than some shitty ass tasting beer or wine
