Diet and exercise play a vital role in cancer prevention. While some cancer risk factors, such as genetics and the environment, are beyond our control, research suggests that about 70% of an individual's lifetime risk of cancer is modifiable. This includes maintaining a healthy weight through a balanced diet and regular exercise. Eating a diet high in saturated fat increases the risk of many types of cancer, whereas a diet rich in fruits, vegetables, whole grains, and healthy fats may protect against cancer. In addition, limiting red and processed meat, as well as reducing sugar and alcohol intake, can help lower the risk of certain cancers.

What You'll Learn
Maintaining a healthy weight
To maintain a healthy weight, it is important to follow a nutritious eating pattern and exercise regularly. This includes eating a variety of healthy foods, such as fruits, vegetables, whole grains, low-fat dairy, and lean proteins. It is also important to limit portion sizes, control calorie intake, and be physically active. Walking is a good way to add more physical activity to your lifestyle, and regular physical activity provides immediate and long-term health benefits. Getting enough water every day is also important for maintaining a healthy weight.
In addition to healthy eating and physical activity, optimal sleep and stress reduction are crucial for maintaining a healthy weight. Maintaining a healthy weight can be challenging, and it is important to consult a healthcare professional before making any significant changes to your diet or exercise routine. They can provide guidance and support to ensure that any changes you make are safe and appropriate for your individual needs.
A healthy weight is an important part of a cancer-fighting strategy. Obesity is a cause of 13 different types of cancer, and maintaining a healthy weight can help reduce this risk. A healthy diet that includes high-fiber foods, such as whole grains, fruits and vegetables, can also help lower the risk of colorectal cancer and other common digestive system cancers. Limiting saturated fat from red meat and dairy to no more than 10% of daily caloric intake is also recommended to reduce the risk of cancer.
Overall, maintaining a healthy weight involves a combination of healthy eating, regular physical activity, optimal sleep, and stress reduction. It is important to remember that individual weight goals may vary, and it is always best to consult a healthcare professional before making any significant changes to your lifestyle.

Eating fruits and vegetables
Fibre, also known as roughage, is abundant in fruits and vegetables and plays a crucial role in maintaining a clean and healthy digestive system. It helps move cancer-causing compounds through your digestive tract, reducing their potential to cause harm. A high-fibre diet is particularly linked to a decreased risk of colorectal cancer and other common digestive system cancers, including stomach, mouth, and pharynx cancers. Additionally, fibre helps with weight management, reducing the risk of obesity, which is a contributing factor to 13 different types of cancer.
Vitamins and minerals found in fruits and vegetables offer a range of health benefits that can indirectly lower your cancer risk. For example, vitamin C, found in citrus fruits and bell peppers, contributes to a healthy immune system, while the potassium in bananas and sweet potatoes supports healthy blood pressure.
Phytochemicals, also called phytonutrients, are natural compounds in fruits and vegetables that can help prevent chronic diseases like cancer. Phytochemicals have been linked to a reduced risk of aerodigestive cancers, including those of the mouth, pharynx, larynx, nasopharynx, and oesophagus.
When incorporating fruits and vegetables into your diet, variety is key. Aim for at least five portions per day, also known as the "5 A DAY" recommendation. Include a mix of fresh, frozen, and tinned options to maximise the diversity of nutrients you consume. For example, fill your sandwiches and wraps with vegetables like tomatoes, cucumbers, aubergines, and peppers. Add fruits like berries, mangoes, or bananas to your morning oatmeal or yoghurt. Snack on fruits or vegetables with a healthy dip like houmous or guacamole.

Consuming high-fibre foods
Consuming a diet rich in high-fibre foods is an effective way to reduce your risk of cancer. Fibre, also known as roughage or bulk, is found in fruits, vegetables, legumes, and whole grains, and it plays a crucial role in maintaining a healthy digestive system. By keeping cancer-causing compounds moving through your digestive tract, fibre helps prevent them from causing harm.
A high-fibre diet is particularly beneficial for preventing colorectal cancer and other common digestive system cancers, including stomach, mouth, and pharynx cancers. Additionally, eating high-fibre foods can help lower your overall calorie intake and maintain a healthy weight, which is crucial in reducing your risk of cancer. Obesity is a cause of 13 different types of cancer, so keeping a healthy weight is essential.
To increase your fibre intake, aim for a variety of high-fibre foods, especially whole grains. The government recommends that adults consume 30 grams of fibre daily, but most people do not reach this amount. You can easily incorporate more fibre into your diet by making simple swaps, such as choosing whole wheat or multigrain bread, brown rice, barley, quinoa, bran cereal, or oatmeal instead of refined grains. Additionally, including more fruits, vegetables, and pulses in your meals is a great way to boost your fibre intake.
High-fibre foods offer numerous health benefits beyond cancer prevention. They can help lower cholesterol and blood sugar levels, promote digestive health, and make you feel fuller for longer. It is important to increase your fibre intake gradually to avoid discomfort. Additionally, staying hydrated by drinking plenty of water is crucial when consuming a high-fibre diet to ensure the fibre doesn't cause stomach problems.
In summary, a high-fibre diet, rich in whole grains, fruits, vegetables, and pulses, is a powerful tool in cancer prevention. By keeping a healthy digestive system and maintaining a healthy weight, you can significantly reduce your risk of cancer, particularly bowel cancer.

Limiting red and processed meats
Research suggests that about 70% of your lifetime risk of cancer is within your power to change, including your diet. Eating a healthy, balanced diet can reduce your risk of cancer and help you maintain a healthy weight or lose weight. Obesity is a cause of 13 different types of cancer.
Red and processed meats have been linked to an increased risk of cancer. The World Health Organization has classified processed meats, including ham, bacon, salami, and frankfurters, as a Group 1 carcinogen, meaning they are known to cause cancer. Eating processed meat increases your risk of bowel cancer and stomach cancer. The nitrite and nitrate preservatives used to preserve processed meat produce N-nitroso chemicals, which can lead to bowel cancer. The risk of developing bowel cancer increases 1.18 times for every 50 grams of processed meat eaten per day. Eating about 2 oz. (50 grams) of processed meat per day increases your risk of colorectal cancer by 20%.
Red meat, such as beef, lamb, and pork, has been classified as a Group 2A carcinogen, meaning it probably causes cancer. When a chemical in red meat called haem is broken down in the gut, N-nitroso chemicals are formed, which can damage the cells that line the bowel and lead to bowel cancer. The risk of bowel cancer also increases with the amount of red meat consumed. Eating more than 700 grams of red meat per week increases your risk of bowel cancer.
To reduce your risk of cancer, it is recommended to limit your consumption of red and processed meats. The Cancer Council recommends eating no more than one serving of lean red meat per day or two servings three to four times per week. A serving of red meat is equal to 90-100 grams raw or 65 grams cooked. Processed meats should be cut out or kept to an absolute minimum. The government recommends that people who eat a lot of processed and red meat should cut down to 70 grams or less per day.
You can make small changes to your diet to reduce your consumption of red and processed meats. For example, you can try meat-free Mondays, find new recipes that use chicken or fish instead of red meat, substitute meat in your usual dishes for pulses like beans or lentils, or reduce your portion size when eating red meat.

Drinking water instead of soda
Research suggests that about 70% of your lifetime risk of cancer is within your power to change, including your diet. Drinking water instead of soda can be a great step towards preventing cancer.
Firstly, it is important to understand that obesity is a cause of 13 different types of cancer. Drinking soda can lead to weight gain and obesity due to its high sugar content. According to the Dana-Farber Cancer Institute, a single can of cola averages about 39 grams of sugar, far exceeding the recommended daily intake of less than 25 to 36 grams. Therefore, switching to water can help maintain a healthy weight, reducing the risk of cancer.
Secondly, artificial sweeteners commonly found in diet sodas, such as aspartame, sucralose, and saccharin, may have negative health effects. While the direct link between these sweeteners and cancer is still being researched, they have been associated with altering gut bacteria, which can result in hyperglycemia and diarrhea. Additionally, these sweeteners are several hundred times sweeter than sugar, potentially leading to cravings for other sweet foods. As a result, individuals who consume diet beverages often compensate by eating more calories from food, which can contribute to weight gain and, consequently, an increased risk of cancer.
Moreover, both regular and diet sodas can negatively impact dental health. The carbonation process in sodas produces carbonic acid, which becomes more acidic when combined with flavoring agents, potentially causing dental issues. While carbonated water also contains carbonic acid, it is not as harmful to teeth as soda, which contains higher amounts of sugar. Therefore, switching to water can help mitigate the negative effects of acidic beverages on dental health.
Finally, drinking water instead of soda can help reduce your overall sugar intake, which is crucial in lowering the risk of cancer. Excessive sugar consumption, often due to sugary beverages like soda, can lead to health complications such as weight gain, poor dental health, diabetes, and cardiovascular disease. These conditions can increase the risk of developing cancer. By choosing water over soda, you can effectively reduce your sugar intake and lower your cancer risk.
In conclusion, drinking water instead of soda can be a significant step towards cancer prevention. It helps maintain a healthy weight, avoids the potential negative effects of artificial sweeteners, mitigates dental health issues, and reduces overall sugar intake, all of which contribute to lowering the risk of cancer.
