Are Butter Biscuits Acidic or Alkaline?
Butter biscuits (baked) are acid-forming: Positive PRAL: acid-forming after digestion.
Classification
Butter biscuits are wheat dough baked dry with butter and sugar. Without water, the protein and phosphorus from the flour are concentrated, hence +5.8. The butter itself adds little to the balance. It mainly supplies energy, and together with the sugar that comes to 456 kcal per 100 g. A piece of fruit with a few biscuits offsets the acid, but the PRAL says nothing about the sugar.
In the Sweets & Snacks category, butter biscuits (baked) rank #78 of 91, sorted from alkaline to acid-forming. More alkaline options include Pretzel sticks (+5.4), Cheese cream torte (+5.2), Crackers (salty) (+4.8). More acid-forming are Spekulatius cookies (+5.9), Chocolate cake (+6.2), Cheesecake (+6.2).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.
What balances butter biscuits
A small serving (40 g) of butter biscuits adds +2.3 to your daily balance. These three bring it back; the grams shown offset exactly this serving.
Frequently Asked Questions
Are butter biscuits acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Butter biscuits (baked) have a PRAL of +5.8 per 100 g, so they count as acid-forming in your daily acid-base balance.
How much kale offsets a small serving (40 g) of butter biscuits?
A small serving (40 g) of butter biscuits adds +2.3 to your daily balance. Kale (fresh) has −11.7 per 100 g, so about 20 g of kale offset this serving.
Do I have to avoid butter biscuits on an alkaline diet?
No. What counts is the balance of the whole day, not a single food. Butter biscuits are acid-forming; with enough vegetables, potatoes and fruit on the same plate, the meal stays balanced.
