The Difference between Body pH and Urine pH. It's not true that the acidity of the body can be changed significantly by diet.

How heavy is an average cucumber in grams, the size you might find in Tesco? Small, average (about 5 1/2 inches length) weighs 158g. Medium, average (about 6 to 7 inches length) weighs 201g. Large, average (about 7 1/4 to 8 1/2 inches length) weighs 280g.
One cup sliced cucumber, for example, contains just 15 calories, 0 gram of fat and 1 gram of fiber, and is very low in sugar and sodium. Aim for at least 2 1/2 cups of vegetables per day.
