Regarding food and overall nutrition I guess. Keep a mental or written diary of food you eat. Typically pulse and heart may go up after eating sugars. Now sugars actually mean sugar, fruit (is loaded with fructose), pasta (starches turn to sugar) honey, maple syrup or any of those artificial sweetners, corn syrup, fructose and other sugar ingredients in food. Once you read labels you’ll be surprised on how much sugar is actually in food. Maybe you’ll discover what makes you speed after you eat by process of diary and elimination of foods. Good Luck!
