Blackcurrant is a fruit in the Grossulariaceae
family of plants, it is also sometimes known as cassis. Other plants in this family include gooseberry and redcurrants. These are all very closely related berries, all of the genus Ribes
Like other berries, blackcurrants are high in Vitamin C (also known as Ascorbic Acid), so eating a lot of the fruit can result in gastrointestinal symptoms which can look like a food intolerance.
There is a study showing redcurrants containing Lipid Transfer Proteins
, so it is likely that gooseberries and blackcurrants also contain these proteins as they are so closely related.
Blackcurrant are a low FODMAP food when eaten in normal small portions.
stands for F
olyols. Foods high in FODMAPs can cause symptoms of food intolerance, affecting the gastro intestinal system and this can be mistaken for a true IgE food allergy.
Blackcurrants are a food high in salicylates
. Salicylates have the potential to cause worsening of asthma, swelling, itching and hives as well as food intolerance symptoms in people who are sensitive to salicylates.
You can read more about Food Intolerances
on the dedicated Food Intolerance Page.
As they may contain Lipid Transfer Proteins, blackcurrants may be linked to LTP Syndrome
, which is where you suffer from allergic reactions to most foods which contain LTP Proteins.
There is a possibility of cross reactivity with other currants in the Grossulariaceae
family of plants.
Other foods which contain LTPs include almond, apple, blueberry, brocolli, cabbage, goji berry, kiwi, lemon, lettuce, orange, pea, peach, peanut, plums, raspberries, walnuts and wheat.
