Are The Exotic Fruit Juices Like Noni and Goji Safe For Human Consumption?

DrYoung It is often said that 'acidic' fruits like lemons, limes and grapefruits will acidify the blood and tissues. In fact, the citric, lactic, and other acids in such low sugar fruits - unlike high sugar fruits - exsist primarily in their anionic (basic or electron) form, especially as their Na+ and K+ salts (e.g., potassium citrate). Following absorption, these anions (bases or electrons) are metabolized to sodium bicarbonate. Thus, lemons, limes and grapefruits alkalinize - not acidify - blood and tissues. Alkalinization occurs - even though the pH is typically low - because free cations (protons or acids) are more than directly offset by the generated sodium bicarbonate from the low sugar fruit. For example, a liter of lime juice with a pH of 4, has 10 to the minus 4 moles of free cations (protons or acids). The quantity of organic anions (bases or electrons) in the lime juice far exceeds this number of free cations (protons or acids) and therefore, a net alkalinization will occur.

This net alkalinization does not occur with high sugar fruit drinks like grape juice or grape juice concentrate, pear juice or pear juice concentrate, apple juice or apple juice concentrate - all found as ingredients in Goji Juice. The Goji Juice has a pH of 3.65, an ORP of +181 mV, a rH2 of 25.81. Furthermore, with the additional 132 grams of sugar per liter or 4 grams per 30 ml (1 liter of Goji Juice contains over 1/4 pound of sugar) , the cations (protons or acids) from sugar metabolism will drive the pH as low as 1.50, the ORP in excess of +500 mV, and the rH2 over 30, making this beverage highly acidic and toxic to the body. Summary: The quantity of organic cations (protons or acids) from high sugar fruits and fruit drinks like Goji Juice significantly exceeds the number of free anions (bases or electrons). Therefore, a net acidification occurs in the blood and tissues.

When testing the saliva or urine after drinking a high sugar fruit drink like the Goji Juice, your result will be a false positive. The acidic fruit juice beverage with its high sugar content (Goji juice has 4 grams of sugar per ounce or 20% sugar by volumn) will cause the pH of the saliva or urine to immediately increase by 1 or 2 points, or 10 to 100 times on the pH scale. This activates the body's buffering system and causes a release of sodium bicarbonate from the salivary glands to nuetralize the cations (protons or acids) from the highly acidic fruit or fruit juice. This release of sodium bicarbonate from the salivary glands causes a reduction in the overall alkaline reserves of the body, and further acidifies the blood and tissues.

A prime example of this is found when the bones of our body are used to buffer the acids from eating or drinking acidic fruits. About two thirds of bone mass consists of inorganic minerals, especially hydroxyapatite (Ca10(PO4)6(OH)2), but also brushite (CaHPO4) and the sodium, potassium and calcium salts of carbonate (CO3). When you mentally dissect these formulas it becomes clear that bone contains a huge potentail source of cation (proton or acid) acceptors, including PO4-, HPO6-, OH-. and CO3-. Thus, bone dissolution can help mitigate a fall in pH from eating or drinking high sugar fruits and fruit drinks. During metabolic acidosis from the sugars in the fruit and fruit drinks, carbonate on the bone surface acts as a proton acceptor. An important mechanism appears to be the chemical exchange of free protons from the acidic fruit sugar bound to the carbonate. The buffering reaction is: 2H+ + CO3- <=> CO2 + H2O

During states of metabolic acidosis buffering takes place through a combination of (1) direct chemical exchange with bone cations (protons or acids), just as during as the buffering of metabolic acids from the acidic fruit sugars, and (2) increased activity of osteoclast cells, which help mobilize additional bone mineral. Both acute and chronic bone buffering lead to the urinary excretion of bone calcium, which will reduce bone mass (osteopenia), cause calcium stone formation in the kidneys, and cause a sudden rise in the pH of the urine. All of this high sugar fruit eating and drinking may not only cause bone loss and calcium stone formation, but also eventually lead to renal damage and then renal failure.

Conclusion: Eat and drink all the low sugar fruits and fruit drinks like avocados, peppers, lemons, limes and grapefruits because they will alkalize the blood and tissues. They add to the alkaline reserves, not reduce the alkaline reserves of body and therefore a net alkalinization occurs. Do not eat or drink high sugar fruits or fruit drinks from apples, organges, mangos, pineapples, bananas, peaches, pears, watermelons, strawberries, blueberries, just to name a few. Even the popular exotic fruit juice drinks like Mangosteen, Noni, Xango, Thai-Go, G3, and Goji will acidify the blood and tissues and deplete the alkaline reserves of the body which may result in bone loss, calcium stones in the brain, breast, liver and kidneys, and/or renal failure.

In order to achieve outstanding health, energy and vitality one must maintain the alkaline design of their body with an alkaline lifestyle and diet.
