Yes — the evidence is strong. Research published in peer-reviewed journals including the American Journal of Clinical Nutrition has shown that diets high in acid-forming foods increase urinary calcium excretion and bone resorption markers, while diets high in alkaline-forming fruits and vegetables are associated with better bone density. Dr. Brown’s clinical experience over 40+ years confirms that shifting toward an alkaline-forming diet consistently supports improved bone health outcomes.

The Alkaline for Life diet is Dr. Susan Brown’s evidence-based nutritional program designed to support optimal bone health by reducing the dietary acid load. It emphasizes: 7-10 servings of fruits and vegetables daily, adequate lean protein, healthy fats, limited processed grains and sugar, and avoidance of excess sodium and alcohol. Unlike extreme alkaline diets, the Alkaline for Life approach is balanced, practical, and nutrient-rich.

The most alkaline-forming foods include: all vegetables (especially leafy greens, broccoli, sweet potato, beets), most fruits (especially citrus, berries, banana, melon), almonds, seeds, most legumes, and some dairy (yogurt, milk). These foods leave an alkaline “ash” after metabolism that helps neutralize excess acid — protecting bones from having to sacrifice their mineral content.

The most acid-forming foods are: processed grains (white bread, pasta, crackers), high-sodium processed and packaged foods, excessive red meat and poultry (especially without balancing vegetables), soft drinks and colas (also high in phosphoric acid), alcohol, and refined sugar. None of these must be completely eliminated, but they should be significantly reduced relative to alkaline-forming foods.

Changes in urinary pH can be measured within days of shifting to an alkaline-forming diet. Bone turnover markers (blood tests that show bone resorption and formation rates) typically improve within 3-6 months. Actual bone density changes as measured by DEXA scan are slower — typically 1-2 years — because bone remodeling is a gradual process. The alkaline diet also provides immediate benefits for energy, digestion, and inflammation.

You can test your urine pH with inexpensive pH test strips (available at pharmacies or online). A healthy urine pH of 6.5-7.5 suggests reasonable alkaline balance. Consistently acidic urine (below 6.0) is a signal that your diet may be too acid-forming. A food diary review with a nutritionist can also identify the main acid-forming culprits in your daily eating pattern.

A study published in Bone (2021) found that women with osteoporosis who drank alkaline water showed modest improvements in bone density compared to those drinking regular water. While alkaline water is not a replacement for an alkaline diet and comprehensive bone-building program, it may provide a small additional benefit. Dr. Brown considers it a supportive measure, not a primary intervention.
