One of the most common treatments for cancers is chemotherapy. One of the side effects of the treatment is a metallic taste to food.
Researchers from Virginia tech are looking into why that happens.
Experts say almost half of chemo patients suffer from malnutrition simply because they don't like the taste and smell of foods and drinks.
They hope to identify the cause of the metal taste and are looking into possibly using antioxidants to prevent the taste.
