⚠️ Watch-outs & how to enjoy it better
Its high natural sugar content (9.1g per 100g) can cause blood sugar spikes, and its acidity may aggravate acid reflux or irritate sensitive teeth. To counteract, consume it with a source of protein or fat (like Greek yogurt or nuts) to slow sugar absorption, and rinse your mouth with water afterward.

FAQ
Is freshly squeezed grapefruit juice healthier than store-bought?
Yes, freshly squeezed juice retains more heat-sensitive nutrients like vitamin C and contains no added sugars or preservatives, but it also lacks the pasteurization that kills harmful bacteria.
Why does grapefruit juice interact with some medications?
Compounds in grapefruit (furanocoumarins) inhibit an enzyme in your gut that breaks down certain drugs, leading to dangerously high levels of the medication in your bloodstream.
Can I freeze freshly squeezed grapefruit juice?
Absolutely. Pour it into ice cube trays or airtight containers, leaving headspace for expansion. It will maintain best quality for 3-4 months.
