And acid-forming foods are things like:
Sugar, gluten-containing grains, excessive animal protein, trans-fats, oxygenated fats, additives, preservatives, flavourings & colorings (natural or otherwise), alcohol, caffeine, chocolate, pizza, chips, refined foods, fast foods, fried foods, battered foods, oven meals, microwave meals, takeaways, wheat and flour products, cola and soda, sweeteners and creamers...
When you see these types of foods, it all makes sense. It's good, clean, healthy living with a focus on avoiding the most acidic, oxidising, inflammation-causing foods, and a big focus on those alkaline, nutrient-dense, antioxidant-rich, anti-inflammatory foods.
Plus of course good hydration, good exercise, as little stress as possible and everything in balance and moderation.
