Do starches and carbs in the diet have a positive or negative effect on the production of these beneficial omega-3 fatty acids?

Normally a negative effect – high glucose (sugar) levels from starches and carbohydrates cause the body to increase its natural production of insulin, which in turn converts DGLA, an omega 6 fatty acid, to arachidonic acid (AA), which is the main culprit in prolonging the pro-inflammatory cause of accelerated chronic disease.
