Do you like kiwis? I like the a lot. And they are very useful for health. Raw kiwi contains actinidain, a protein-dissolving enzyme that can help to improve the digestion of heavy meals much like the papain in papaya or bromelain in pineapple.Kiwi’s high level of potassium helps keep our electrolytes in balance by counteracting the effects of sodium.Kiwis are a great source of fiber. This prevents constipation and other intestinal problems. The fuzzy fiber of Kiwi helps bind and move toxins from your intestinal tract.
