Original sentence: Food combining is the term for an unproven nutritional approach that focuses less upon the quantity and kind of food consumed, and more upon the timing of their consumption.For example, advocates sometimes recommend that carbohydrates and citrus fruits should not be consumed at the same meal, claiming that the enzyme that digests carbohydrates (amylase) can only function in an alkaline environment.Many of the assumptions used to justify food combining are not supported by biological and medical science, and there is currently little evidence supporting real-world success for these theories.One randomized controlled trial has been reported in the peer-reviewed medical literature, which found no evidence that food-combining principles were effective in promoting weight loss
Edited sentence: Food combining along with a proper alkaline diet--while still very contemporary sciences--are changing everything we thought to be true about human health.Food combining is the term for a nutritional approach that focuses not only on the quantity and kind of food consumed, but also on the timing of their consumption.For example, advocates recommend that animal products and vegetables should not be consumed at the same meal, because while vegetables move quickly and easily through the body, meat takes approximately 48 hours to be fully digested.These new ideas are changing our preconceptions of the conventional "aging process": what we once thought to be a normal process appears to be the body decaying from improper care.While these ideas are still in a very early stage, they will continue to grow with the coming years
