Are pineapples alkaline or acidic?

Pineapples are considered very acidic fruits. Among the acidic fruits, we can find fruits that are not fully ripe (the less ripe, the more acidic they are). Citrus fruits in general, except lemon which become alkaline in the stomach.

Fruits with an acid taste, as well as their juice, are: pineapple, kiwi, passion fruit, all berries (strawberries, raspberries, blackberries, and others), certain varieties of apples such as Granny Smith, cherries (alas!), apricots and plums. And also some dried fruits such as plums, figs, and apricots. We can classify prunes a little differently, and associate them with semi-acidic fruits.

A little tip for dried fruits: you can soak them overnight in water and eat them the next day after discarding the soaking water!

Semi-acidic fruits: Most apples, blackberries which are part of berries, blueberries, mangoes, nectarines, peaches, and pears.

Sweet fruits: Bananas, dates, figs, persimmon, grapes, and papaya.

As a reminder: it is best to consume all kinds of melons and watermelon on their own!

Also, remember that the digestion time of a fruit differs depending on the category to which it belongs.

A sweet fruit, for example, can take up to four hours to digest, whereas a semi-acid fruit will take only two hours and a sour fruit only an hour! This is why it is important to know precisely to which group each fruit belongs.

It is better to consume whole fruits than to pass them in a blender to make a juice or a smoothie, even if you digest them better, they will not allow you to last very long, except, of course, if you have incorporated a dark green vegetable or vegetable milk.

After consuming a fruit meal, it is better to wait three hours before eating anything else so as not to disrupt the digestion phase, and it is also better to avoid combining sweet and sour fruits in the same meal.

The great thing about fruits is that they can be eaten raw, cooked, or prepared. Thus, you can eat them in the morning in squeezed juice or in pieces in your cereals, at midday as a compote or whole fruit dessert, and in the evening in the form of skewers and if you find them bland, consider choosing the ripest fruits, they have more taste!

Bromelain, the main substance in pineapple is a particularly useful enzyme for digestion, pineapple being among the few fruits recommended by nutritionists to be eaten immediately after a hearty meal.
