The Paleo diet and alkaline diet have many things in common and a lot of the same benefits, such as lowered risk for nutrient deficiencies, reduced inflammation levels, better digestion, weight loss.
They both eliminating added sugars, reducing intake of pro-inflammatory omega-6 fatty acids, eliminating grains and processed carbs, decreasing or eliminating dairy/milk intake, and increasing intake of fruits and veggies.
The Paleo diet eliminates all dairy products, including yogurt and kefir, which can be valuable sources of probiotics and minerals for many people — plus the Paleo diet doesn't always emphasize eating organic foods or grass-fed/free-range meat (and in moderation/limited quantities).
The Paleo diet tends to include lots of meat, pork and shellfish, which have their own drawbacks.
Eating too many animal sources of protein in general can actually contribute to acidity, not alkalinity. Beef, chicken, cold cuts, shellfish and pork can contribute to sulfuric acid buildup in the blood as amino acids are broken down. Try to obtain the best quality animal products you can, and vary your intake of protein foods to balance your pH level best.
