Fruit Groups: What you need to know.

Fruits are made up of four groups. Acid fruits, sub-acid fruits, sweet fruits, and melons.

Typically you never want to mix any of the fruits with any other food group, each group should be eaten separately. Fruits travel through the digestive track very quickly, typically within an hour which is why you don’t want to eat them with other food groups.

From personal experience, I do notice that I feel better when I group foods together depending on how long it takes for them to digest. For example I would eat a pineapple and wait at least 30 mins before eating porridge or something else. However, this could just be a placebo effect as this is based on a theory, I don’t know of any scientific studies that support this. In fact, in an interview Dr. Michael Greger (Americal plant-based physician) himself said that food grouping is nonsense.

Acid Fruits: They have the most fibre and are rich in antioxidants. Approximate digestion time is 20 to 30 minutes.

  • Blackberry
  • Sour cherries
  • Cranberry
  • Gooseberries
  • Sour grapes
  • Grapefruit
  • Kumquats
  • Lemon
  • Lime
  • Longanberries
  • Orange
  • Pineapple
  • Sour plum
  • Pomegrante
  • Raspberry
  • Sour apple
  • Strawberry
  • Tangelo
  • Tangerine
  • Tomatoes

Sub-Acid Fruits: Approximate digestion time is 30 to 40 minutes.

  • Apple
  • Apricot
  • Blueberry
  • Cherry
  • Grapes (not sweet or sour)
  • Kiwi
  • Lychee
  • Mango
  • Nectarine
  • Papaya
  • Peach
  • Pear

Sweet Fruits: They are more concentrated and take longer to digest. They’re not the greatest of cleansers but they do provide minerals and concentrated sugars. Approximate digestion time is 40 to 60 minutes.

  • Currents
  • Sweet plum
  • Dates
  • Figs
  • Sweet Grapes
  • Papaya
  • Persimmon
  • Prunes
  • Raisins
  • Banana

It is okay to combine acid and sub-acid fruits, as well as sub-acid with sweet. However I if you want to follow the approach of food combining I would not combine acid and sweet fruits.

Any type of Melon should be eaten on its own as it is the fastest digesting fruit.
