When we eat carbohydrates (sugar or starch), the amount of sugar in our blood increases. Our pancreas is then supposed to release insulin into our blood. Insulin tells our cells to pick up the sugar and use it for energy (so that the sugar is not floating around freely in our blood causing toxicity and harm).
HOWEVER - if there's too much sugar for the pancreas to keep up with, or, if the cells stop responding to the insulin, we have a huge problem.
The pancreas produces tons more insulin, and in time, the cells become even more resistant to the insulin! The pancreas cells can even become damaged when this happens, putting us in a real danger zone for long-term harm.
At this point - blood sugar (glucose) and insulin levels in the blood would be extremely, extremely high after eating carbs, necessitating all sorts of continual medical interference.
We eat SO MANY starches and sugars in our American diet, it's like a death-wish to our systems. All starch converts to sugar - so it doesn't matter if you "don't like sweets." Chances are you're still eating tons and tons of carbohydrates, most of which convert almost immediately to sugar.
Even seemingly innocent things like Rice Krispies, tortilla chips, whole grain bread, orange juice, rice, and sweetened iced tea are total sugar bombs to our blood stream.
I'm not advocating for a pure paleo diet (unless you're on the brink of a health crisis). What I am advocating is replacing a large number of your carbs and sugars - even those from fruit and "whole-grain" and gluten-free products) with more protein and vegetables.
Your pancreas and glucose levels will thank you, and you will hopefully avoid falling into the 1/3 of the American population that continually suffers from these things and depends on medical interference.
In a study by Carol Johnston at Arizona State University, subjects taking apple cider vinegar before meals had significantly lower blood sugar (glucose) levels after eating than the control group. They also found that the subjects taking apple cider vinegar lost weight!
Subjects who were resistant to insulin became more sensitive to insulin (a very good thing!) after consuming the vinegar.
In another study, when subjects with high glucose conditions consumed apple cider vinegar before bed, their glucose levels upon arising were reduced by 6% compared with their regular waking glucose levels.
There is a percentage of the population whose immune systems have destroyed the cells that produce insulin. Apple cider vinegar seems to be effective on reducing post-meal glucose levels for that part of the population as well.
