Oral cancer includes cancers of the mouth, tongue, lips, throat, tonsils, and salivary glands. Lifestyle choices, such as smoking and alcohol consumption, can significantly increase the risk of developing oral cancer, but so can one's diet.
Oral cancer, like all cancers, results from the uncontrolled growth and division of cells. The exact cause of any individual's cancer may be hard to determine, but there are known risk factors that can contribute. The leading causes of oral cancer are tobacco and alcohol, along with infections from the human papillomavirus (HPV). A healthy diet doesn't guarantee immunity from the disease, but it can reduce the odds.
What does the ideal plate look like in the context of oral cancer prevention? There's no diet that fits all, but a balanced and nutritious approach is universal. It includes a variety of foods rich in nutrients that help the body fight diseases. Foods that are high in vitamins, minerals, and antioxidants, such as fruits and vegetables, fall into this category.
Fruits and vegetables are rich in antioxidants, which help keep cells healthy by protecting them from damage. Some studies suggest that a diet high in fruits and non-starchy vegetables may help protect against oral cancer. The key is to aim for a rainbow of colors to ensure you're getting a broad spectrum of nutrients.
Citrus fruits, such as oranges and limes, are particularly rich in vitamin C, a powerful antioxidant, and they've been studied for their potential in cancer prevention. However, those who have a history of gastroesophageal reflux disease (GERD) should be cautious, as the acid in these fruits can be irritating.
Cruciferous vegetables like broccoli, cabbage, and kale contain compounds that have been linked to reduced cancer risk. Additionally, carotenoids, found in sweet potatoes, carrots, and tomatoes, have also been studied for their protective effects.
Whole grains provide fiber and a range of vitamins and minerals. They're also a source of phytochemicals, which have been studied for their cancer-preventing properties. Whole grain foods include oatmeal, brown rice, quinoa, and whole wheat bread.
Including lean proteins in your diet is crucial for overall health. Healthy sources of protein include fish, poultry without skin, beans, and legumes. Fatty fish, like salmon and trout, are high in omega-3 fatty acids, which have anti-inflammatory properties that could help protect against certain cancers.
Consuming red meat and processed meats like bacon or sausage has been linked to an increased risk of cancer, so it's best to limit these foods or consider substitutes.
Diets high in saturated fats have been associated with an increased risk of cancer. When choosing fats, opt for healthier unsaturated fats like those found in nuts, seeds, and avocados. Use olive oil, which is a monounsaturated fat, as your primary cooking oil.
Ensuring you're well-hydrated is a crucial part of cancer prevention. Water helps to flush out toxins and aids in digestion. A good rule of thumb is to drink at least eight glasses of water per day, but individual needs vary.
Sugary foods and drinks can contribute to weight gain and obesity, which are significant risk factors for cancer. They can also lead to tooth decay, which may increase the risk of oral cancer.
Certain nutrients in foods have been the focus of scientific inquiry for their potential in oral cancer prevention. Here are a few to keep in mind.
Vitamin A is crucial for maintaining a healthy immune system and is an essential part of the body's natural defense system. Beta-carotene, a type of vitamin A, is found in brightly colored fruits and vegetables such as carrots, sweet potatoes, and spinach.
This vitamin is a powerful antioxidant that can help neutralize free radicals, which can damage DNA and lead to cancer. It's abundant in citrus fruits, strawberries, and bell peppers.
Another potent antioxidant, vitamin E, is found in nuts, seeds, and vegetable oils.
Selenium is a mineral found in certain foods and it's also available as a supplement. It's particularly concentrated in Brazil nuts, fish, and poultry.
Zinc is important for the immune system and wound healing. It's found in a variety of foods, including oysters, red meat, poultry, beans, nuts, and whole grains.
These are found in fatty fish like salmon, mackerel, and sardines, as well as in flaxseeds and walnuts. They play a role in inflammation and in the normal functioning of the immune system.
Found in whole grains, fruits, and vegetables, fibers can bind to and help remove potential carcinogens from the gut before they can cause harm.
While it's essential to focus on what to add to your diet, it's also important to consider what to avoid.
Excessive alcohol consumption is one of the leading risk factors for oral cancer. According to the Centers for Disease Control and Prevention (CDC), heavy drinking is defined as consuming 15 or more drinks per week for men and 8 or more drinks per week for women.
It's been linked to the development of oral cancer, particularly in those who drink large amounts of soda.
These have been associated with an increased risk of various types of cancer, including oral cancer.
Putting all these principles into practice can seem daunting, but the variety and richness of a healthy diet can offer a surprising number of delicious meals.

Here are a few strategies to help you maintain a diet that is optimal for oral cancer prevention:
Invest time in planning your meals for the week and preparing your shopping list accordingly. This will make it easier to stick to a healthy diet and avoid the temptation of unhealthy choices.
The perimeter of the store is typically where you'll find fresh produce, lean proteins, and whole grains. Many of the processed and less healthy options are usually found in the center aisles.
Keep a variety of healthy snacks like fruits, nuts, and cut-up vegetables readily available. This will help you avoid the urge to reach for unhealthy options when you're hungry.
When you cook at home, you have more control over the ingredients in your meals. You can avoid added sugars, unhealthy fats, and excessive salt.
The link between diet and cancer is complex, but evidence suggests that a diet high in fruits, vegetables, whole grains, and lean proteins can reduce the risk of developing oral cancer. Combining these dietary choices with regular exercise, and avoiding tobacco and excess alcohol, can significantly improve your overall health profile.
