There is some evidence that an alkaline diet – one that emphasizes nutrition such as leafy green vegetables (such as kale, Swiss chard, arugula, spinach, etc.), fruits and unprocessed plant-based protein sources – can result in health benefits such as these (reported in this article “The Alkaline Diet: Is There Evidence That an Alkaline pH Diet Benefits Health?” from the Journal of Environmental and Public Health)
- “Increased fruits and vegetables in an alkaline diet would improve the K/Na ratio and may benefit bone health, reduce muscle wasting, as well as mitigate other chronic diseases such as hypertension and strokes.
- The resultant increase in growth hormone with an alkaline diet may improve many outcomes from cardiovascular health to memory and cognition.
- An increase in intracellular magnesium, which is required for the function of many enzyme systems, is another added benefit of the alkaline diet. Available magnesium, which is required to activate vitamin D, would result in numerous added benefits in the vitamin D apocrine/exocrine systems.
- Alkalinity may result in added benefit for some chemotherapeutic agents that require a higher pH.”
As the video on this page suggests, the goal of a healthy “alkaline diet” isn’t to completely eliminate acidic foods (such as blueberries and other berries, lemons and other citrus fruits, apple cider vinegar, bone broth, etc.) but to balance the diet providing optimum health and nutrition … and generally make the resulting urine pH slightly alkaline.
Other articles suggest that most of the alkaline diets found in many places work, but sometimes not for the reasons suggested. Another article from Authority Nutrition: (The Alkaline Diet: An Evidence-Based Review) reaches similar conclusions suggesting the foods emphasized by an alkaline diet make sense, but some of the specific premises may be incomplete:
“Unlike many other strange diets, the alkaline diet is actually quite healthy. It encourages a high consumption of fruits, vegetables and healthy plant foods, while restricting processed junk foods. However, the claims about the mechanism behind the diet are NOT supported by evolutionary evidence, human physiology or any reliable study in humans. …”
This WebMD article provides additional insights and suggestions regarding restricted foods and challenges.
Many advocates of an alkaline diet suggest that with a well-balanced, predominantly plant-based diet, it should be possible to get one’s nutritional needs met by just the diet alone. However, if availability of high quality, fresh (preferably organic) produce and/or lifestyle and scheduling, etc. preclude achieving this optimal dietary balance, it might make sense – always consult your physician … and use common sense with the best information available – to explore dietary supplements as an adjunct to the best food intake available via your local grocery and culinary sources.
