According to Mehr news agency, citing New Atlas, this discovery provides the basis for the development of a natural treatment.
Pigments present in natural compounds found in fruits, vegetables, herbs and leaves have several medicinal benefits. Research has shown that pigments can fight forgetfulness, have anti-aging properties, and help produce bread suitable for people with diabetes.
Now, new research by Tokyo University researchers indicates that a special pigment called “kaempferol” can reduce allergic reactions (including food allergies) by affecting the body’s immune system. .
This is while food allergies lead to fever, eczema, and asthma.
In the human intestine, there is a subset of antigen-presenting cells called dendritic cells, which stimulate the critical immune response to cause food allergies. Antigens cells or APCs present antigens (foreign substances that stimulate an immune system response) to T cells to activate them. Dendritic cells produce an enzyme called retinaldehyde dehydrogenase 2 (RALDH2), which converts the retinal chemical derived from vitamin A into retinoic acid. Retinoic acid then triggers the creation of regulatory T cells (T-regs), immune cells that suppress the body’s allergic response.
In the new research, the researchers examined about 40 different types of pigments to determine whether the reactions and efficiency of RALDH2 in dendritic cells increased or not. They found kaempferol to be the most effective pigment in this regard.
Kaempferol is found in abundance in tea, beans, broccoli, apples, and strawberries.
