A lumbar sympathetic block is performed to block the sympathetic nerves that go to the leg on the same side as the injection. This may in turn reduce pain, swelling, color, sweating and other unusual changes in the lower extremity and may improve mobility.
Refined foods have been processed or altered so that they are no longer in their natural state. This results in a loss of beneficial nutrients and fiber. High in calories and low in nutrition, refined foods are easy to overeat and less satisfying than whole foods. Eating them in moderation can help you maintain a healthy weight and reduce your risk of many health issues.
Sweets are also a source of carbohydrate, and include sugar, honey, soda, candy, cake, cookies, doughnuts, ice cream and other confections. Sweets contain simple carbohydrates or sugars. Although refined-carbohydrate foods -- such as white bread, white rice and white pasta -- are made up of complex carbs, they are still processed foods. Sweets and refined carbs are not as nutritious as starches, fruits and vegetables. They lack fiber and are not a natural source of vitamins and minerals.
