I personally think ice cream is the worst offender of the sweets.

It thickens the blood with the fats in it, and impairs circulation for several hours. Tests were done on normal people, and blood draws after high fat consumption, showed very thick blood. We know that increasing viscosity of the blood, with various antibodies or peptides (bone marrow diseases like MGUS), will also give PN as the blood cannot circulate well in the tiny vessels in the hands and feet.

Sugar (with its fructose load) is the next to worst also. But I think we are designed to handle a little fructose because that is in fruit. Excessive sugar (fructose is 1/2 of table sugar), however then puts a load on that way.

So sugar + fat = ice cream

Vit E + fish oil will help thin the blood a bit. So if you think this is a problem for you, try those and see if your circulation improves.
Get the natural type of Vit E and take both oils with food.

Otherwise, just keep plugging along, as you are doing. One day at a time.
