Many believe that cancer is caused by genetics, and while that may be true for some, several studies have shown that lifestyle and diet play just as significant a role in the development of the disease. While there's no guaranteed way of avoiding cancer entirely, knowing which foods to avoid can lower the risk of developing various types of cancer.
Processed foods may appear as though they belong in our everyday diet, but when consumed in excess, they may increase the risk of cancer. Processed foods are high in preservatives, additives, and unhealthy fats. Studies have linked processed foods to colorectal and stomach cancer mainly due to the lack of fibres or presence of carcinogenic substances used in their processing, such as nitrites and nitrates. If you have processed foods in your diet, make sure to consume them moderately or avoid them when possible.
Red and processed meat, such as bacon, sausages, and beef, should be consumed in moderation. Several studies, including a sizable study by the International Agency for Research, have found that consuming processed meat can increase an individual's risk for cancer. When meat is cooked at high temperatures or grilled, carcinogenic substances form, which could contribute to cancer. Instead of consuming large amounts of red and processed meat, try incorporating plant-based proteins such as nuts, seeds, and legumes into your diet.
Sugary drinks, such as soda pop and energy drinks, are high in calories and contain unhealthy amounts of sugar. They also cause spikes in insulin levels that are linked to hormonally-related cancers such as breast and pancreatic cancers. In addition to its contribution to cancer, sugary drinks can lead to weight gain, increasing your risk for other diseases like diabetes and heart diseases.
While moderate drinking may not have severe health risks, consuming alcohol frequently may lead to an increased risk of cancer. According to studies, alcohol is linked to an increased likelihood of developing cancers such as liver cancer, breast cancer, and oropharyngeal cancer, among others. If you're a frequent alcohol drinker, consider reducing your alcohol consumption to promote good health and lower your cancer risk.
Fast foods, such as burgers, fries, and pizza, may not only lead to weight gain but also increase the risk of cancer. Fast-food restaurants use carcinogenic substances, such as acrylamide, PAHs, and heterocyclic amines, in their grilled or fried foods, which contribute to the development of colon, breast, and kidney cancers. While we all indulge in a fast-food diet occasionally, it should always be consumed in moderation.
By no means should you cut out any of these foods from your diet entirely. However, minimising your intake of these foods or replacing them with healthy alternatives can decrease your risk of cancer. It's essential to lead a balanced diet with a range of nutrients, such as vitamins, minerals, and nutrients that our bodies need to function correctly. Eating a balanced diet is a crucial part of reducing an individual's risk of cancer. Remember, prevention is always better than cure.
