Short answer: kale is strongly alkaline-forming and it is approved. It is the food most worth understanding on this list, because of what its approval reveals about the hybrid rule.
The numbers
Kale measures pH 6.40 to 6.80 — just below neutral as a food.
Its PRAL is −8.3, which is strongly alkaline-forming and among the highest of any approved vegetable. Calcium, potassium and magnesium all contribute.
Is kale Dr. Sebi approved?
Yes, without qualification. It appears on every reproduction of the approved vegetable list.
The part worth knowing
Kale is Brassica oleracea. So is broccoli. So are cauliflower, cabbage, Brussels sprouts and kohlrabi. All six are the same wild mustard plant, bred by humans over centuries into different shapes.
Kale is approved. Broccoli, cauliflower and cabbage are not. Same species, same breeding history, opposite verdicts, and no published rule that explains the difference. We go into that in detail on the broccoli page.
If you follow this way of eating and that inconsistency bothers you, it should. It is a genuine gap in the framework, not something you have misread.
How to use it
Massage raw kale with a little approved oil and key lime to soften it. Cooked, it holds up better than spinach and works anywhere you would have used collard greens — which, for what it is worth, are also excluded.
One thing worth being straight about
None of this changes the pH of your blood. Your lungs and kidneys hold it between 7.35 and 7.45 whatever you eat — a reading outside that range is a medical emergency, not a dietary outcome. What food shifts is urine pH, which is your kidneys processing the acid load from your meal. That is the honest extent of what PRAL tells you.
Common questions
Is kale acidic?
Very slightly as a food, around pH 6.4 to 6.8. Strongly alkaline-forming after digestion.
Is kale better than spinach?
Within the framework, kale is approved and spinach is not, which settles it. By measurement spinach is more alkaline-forming, but kale is much lower in oxalates.
Can I eat kale every day?
For most people, yes. If you take thyroid medication, large daily amounts of raw cruciferous vegetables are worth raising with your doctor.
