It could be many things. It could be from slouching or sitting in a way that is causing the diaphragm to be compressed. Do not try to over straighten, just think of relaxing the muscles and allowing yourself to fall into a natural position. It could be injury from working out and doing crunches or other movements. It could be a stomach ulcer.
Another option is to blanch green beans quickly. Blanch your green beans by boiling them for 3 or 4 minutes. This removes the skin of your green beans. You want your beans to be somewhat tender, yet have a little bit of crispness to them. Determine the crispness, by how long you boil them.
Remove and discard the stem end of the beans. Cut beans into 2 to 3-inch pieces (optional). Drop them into a large pot of boiling, salted water and cook at a full boil until theyâve softened but are still firm. Do not cover the pot or their color will fade. Start tasting them after 3 minutes of cooking. When theyâre cooked to your taste, drain, shake dry and season with oil, salt and fresh herbs such as tarragon. Green beans are best served immediately.
