3. Red meat – Some researches have found a link between red meat and an increased risk of breast cancer, especially if a person cooks the meat at high temperatures, which can trigger the release of toxins. In addition, processed meats and cold cuts tend to be high in fat, salt, and preservatives. Red meat contains compounds that can promote inflammation, and form cancerous cells. Hence, it is advisable for individuals with cancer to avoid red meat and opt for other plant-based protein sources, such as legumes, and nuts. (Image Source: Getty)
