For many years, grapefruit has been a staple for people looking to lose weight. It’s satisfying, low in calories, and full of nutrients like vitamins. Known to be extremely acidic, grapefruits contain furanocoumarins that actually keep your stomach from performing some of its regular functions. That doesn’t sound like a good thing! So is this sour fruit a good thing to keep on your countertop? Or should you ditch the grapefruits for other options in the Paleo lifestyle?
Originally a sub-tropical fruit; Grapefruits are the product of natural hybridization; When the two species of plants are crossed and create a new sub-species. In this case, the grapefruit’s parents were from Asia: the pomelo and the sweet orange. The new species took up residence in Barbados and the surrounding area.

Grapefruits have been shown to reduce arterial stiffness, improve blood pressure, and add a healthy dose of vitamins (A, C).

Does that mean that grapefruits are really great or not so much? It can be hard to tell.
What do the Paleo gurus say about grapefruit?
Alison Ver Halen says: “You can…obtain benefits from eating grapefruit. It is low in sugar and high in anti-oxidants, both of which are beneficial.

The fruit has beneficial fiber to lower blood sugar and feed your gut bacteria, whereas store-bought juice is likely to have added sugar.”
Loren Cordain says: “Given…the possibility of increased sugar in juices, my suggestion instead would be to eat grapefruit whole instead. As we recommend with other fruit and vegetables when following a Paleo diet.

This indicates more benefits for you to actually eat a grapefruit, instead of drinking the juice.”
So is grapefruit Paleo?
Yes, but be cautious.
Grapefruits themselves are a great source of nutrients, and they can be tasty and a convenient snack. However, the reason that grapefruits are sometimes considered “dangerous” is because of the furanocoumarins that inhibit gut function. This doesn’t affect your day-to-day stomach health; the only time this will really be important is if you are taking medications. Grapefruit is known to interact with a large number of medications. So, always check to be sure that you can consume grapefruit if you are taking any medicines, either prescribed, over-the-counter, or herbal.

Do some research and ask your doctor before adding grapefruit to your diet; otherwise, you may be neutralizing your medicine as you take it.
