If your doctor suggests you undertake a DASH, Dietary Approaches to Stop Hypertension, meal plan, opt for freshly cooked bamboo shoots over the canned variety. DASH diets emphasize a healthy intake of potassium, a mineral associated with lower blood pressure. A 3.5 oz. serving of home cooked bamboo shoots provides 15 percent of the DV for potassium, yet the same amount of canned bamboo shoots contains only 2 percent of the potassium you should have each day. Both varieties are good sources of copper, manganese and vitamin B 6. Each also provides at least 2 percent of the DV for riboflavin, phosphorus and zinc.
