• Does alkaline water actually have health benefits? - womenshealthnetwork.com - "Synthetic alkaline water can be divided into two groups. One is purified water with added trace minerals. The second is produced by electrolysis and it’s even more artificial. A machine separates the hydrogen (acid-forming) and hydroxyl (alkalizing)components of water and renders two waters, one highly acidic and the other highly alkalizing ... The label on this kind of “alkalizing water” might say it was made by electrolysis. Such waters can have a pH of 9 or above — high enough to inactivate pepsin and decrease stomach acid production. In fact, the only medically approved use of these high pH waters is to treat acid reflux in Japan and Korea. Proponents of alkaline water made through electrolysis make broad claims about its health effects but to date, the only official medical use is for excess stomach acid."

• pH imbalance in brain cells may contribute to Alzheimer's disease - Science Daily, 8/2/18 - "one root of Alzheimer's disease may be a simple imbalance in acid-alkaline -- or pH -- chemistry inside endosomes, the nutrient and chemical cargo shuttles in cells ... the scientists gave drugs called histone deacetylase (HDAC) inhibitors to pH-imbalanced mice cells engineered with a common Alzheimer's gene variant. The experiment successfully reversed the pH problem and improved the capacity for amyloid beta clearance ... mouse cell lines containing the Alzheimer's disease gene variant had more acidic endosomes (average of 5.37 pH) than cell lines without the gene variant (average of 6.21 pH)"
• Is Alkaline Water Really Better for You? - NYT, 4/27/18 - "Blood is tightly regulated at around pH 7.4, while the stomach, which secretes hydrochloric acid to digest proteins and kill food-borne pathogens, is very acidic, with a pH of 1.5 to 3.5. If you drink water that is slightly alkaline, Dr. Fenton said, the hydrochloric acid in the stomach quickly neutralizes it before it’s absorbed into the blood"
• Urinary Citrate Positively Associated With Bone Strength, Health - Medscape, 10/11/16 - "Slight shifts of acid-base status toward a more acidic direction adversely affect bone status. A more alkaline diet rich in fruits and vegetables appears to counteract these shifts and has a long-term preventive medical importance for bone health"
• Higher dietary acid load increases risk of diabetes, study says - Science Daily, 11/11/13 - "A western diet rich in animal products and other acidogenic foods can induce an acid load that is not compensated for by fruit and vegetables; this can cause chronic metabolic acidosis and lead to metabolic complications. Most importantly from a blood-sugar control perspective, increasing acidosis can reduce the ability of insulin to bind at appropriate receptors in the body, and reduce insulin sensitivity ... potential renal acid load (PRAL) ... In the overall population, those in the top 25% (quartile) for PRAL had a 56% increased risk of developing type 2 diabetes compared with the bottom quartile ... A diet rich in animal protein may favour net acid intake, while most fruits and vegetables form alkaline precursors that neutralise the acidity. Contrary to what is generally believed, most fruits such as peaches, apples, pears, bananas and even lemons and oranges actually reduce dietary acid load once the body has processed them" - Note:  Yogurt has a pH of 4.5 (7 is neutral).  I'm hoping that the seven potassium capsules I take per day will counter some of that.
