Basophils
Basophils are the smallest group of white blood cells and take part in the body’s immune and allergic responses.
Basophils are the smallest group of white blood cells, usually less than one percent of them. They contain granules with histamine and other substances, and release them as part of the body’s immune and allergic responses. The count is part of the white blood cell differential and gives context on immune activity.
Allergic reactions, for example during pollen season, a recent infection, stress and some medicines can shift the count. Because basophils are so few, small changes between tests are common.
Foods that help
No food changes basophils directly. A varied diet with vegetables, berries, fatty fish, nuts and fermented foods such as yoghurt.
Foods to limit
Highly processed food, a lot of sugar and alcohol, and foods you know you react to.
