I am very slim. 5'7", 120 lbs. Low BMI, marathoner who runs between 60-80 miles a week. I am vegetarian and don't eat fried stuff at all; the fat I get comes from avocados, almonds, nuts and is a very low fat diet. My diet is based on whole grains, legumes, and fruits. I don't eat refined sugars nor processed food. I don't drink alcohol. Always my cholesterol and triglycerides levels have been very, very low. High triglyceride levels results from today's blood work while maintaining my very low cholesterol levels, blew me away. The only thing I get in excess is fructose from fresh fruits. I eat a lot of fresh fruits. Could that be the culprit?
