Side effects of cashew nuts you didn't know 

Heart

Allergic Reactions

Cashews belong to the tree nut family, and individuals with tree nut allergies may experience allergic reactions to cashews. Symptoms can range from mild itching and swelling to severe anaphylaxis.

Multiple Blue Rings

Cross-Reactivity

People with pollen allergies, particularly birch pollen, may experience cross-reactivity with certain proteins found in cashews. This can lead to an allergic reaction, known as oral allergy syndrome, where the immune system reacts to proteins that are similar to those in pollen.

Multiple Blue Rings

Toxic Resin

Cashews are often sold without their shells because the shells contain a toxic resin known as urushiol, which is also found in poison ivy. Roasting or processing cashews properly can eliminate the toxin, but mishandling raw cashews or consuming them inappropriately processed forms could lead to reactions.

Multiple Blue Rings

Oxalates

Multiple Blue Rings

Cashews contain oxalates, which are compounds that can contribute to the formation of kidney stones in susceptible individuals. People with a history of kidney stones may need to moderate their intake of foods high in oxalates.

Phytic Acid

Multiple Blue Rings

Like many nuts and seeds, cashews contain phytic acid, an anti-nutrient that can bind to minerals and reduce their absorption. This could be a concern for individuals who rely heavily on cashews as a primary source of nutrients.

High Caloric Content

Multiple Blue Rings

While cashews are nutrient-dense, they are also calorie-dense. Overconsumption can contribute to weight gain, especially if not accounted for in a balanced diet.

Processing Additives

Multiple Blue Rings

Some commercially available cashews may be processed with additives like salt, oils, or preservatives. People sensitive to these additives should check labels carefully.

Aflatoxin Contamination

Multiple Blue Rings

Cashews, like many nuts, can be susceptible to aflatoxin contamination, which is a toxin produced by certain molds. Quality control measures during processing are crucial to minimize the risk.
