@Cindy- I also experience negative symptoms when I eat too much starch. My digestion suffers, and I start to feel like my system is slowing down. A low-carb diet is definitely not the solution for me, so I try to eat sugar for a lot of my carbs, although I always eat some starch too.
As an example: today for breakfast I had a couple figs and two cups of coffee with milk and sugar, for lunch I had a McDouble and two large cokes, and for dinner I had a pizza burger and a Klondike bar–and I’ll probably drink some port later. I’d estimate that at least 80% of my carbs today were from sugar. Sometimes I’ll have more starch than this, but my digestion has been bad the last couple of days, so I cut back on it.
