This oil acts on bile acids, improves circulation and oxygenation of tissues, protects arteries and maintains their flexibility. Moreover, it helps reduce the bad cholesterol (LDL), controls blood pressure, and notably reduces the level of sugar in the blood. In addition, it is a powerful antioxidant, which is why it helps to prevent cancer.



Water, though it does not constitute nourishment that provides some type of nutrient or vitamin, is a powerful irreplaceable liquid and life cannot be sustained without it. Without water, no living being could survive, since water helps us to cleanse our body of toxins. People that do not consume adequate amounts of water run the risk of suffering from constipation, which causes an accumulation of toxins, which affects overall health, on top of suffering from dehydration. It is very important to maintain all systems of our body duly hydrated so that our body functions properly. Thus, drinking at least two liters of water per day is absolutely indispensable for our health.
