Phytochemicals, also called phytonutrients, are compounds in plant foods that can help prevent chronic diseases, including cancer. Phytochemicals are part of the plant's immune system, protecting it from viruses, bacteria, fungi, and parasites. They offer humans some of the same protections, acting as chemoprevention by hindering cancer development and preventing DNA damage. They can also repair mutated genes, slow cancer growth, and help abnormal cells die more quickly. Phytochemicals are found in whole grains, fruits, vegetables, nuts, and herbs, with larger concentrations found in the skins or peels of fruits and vegetables. Eating a variety of colourful plant-based foods is the best way to ensure you're getting a range of phytochemicals and other essential nutrients.
| Characteristics | Values |
|---|---|
| Protection against chronic diseases | Phytochemicals may help prevent chronic diseases, including cancer, diabetes, obesity, and cardiovascular diseases. |
| Cancer prevention and treatment | Phytochemicals act as chemoprevention by hindering cancer development and repairing mutated genes. |
| Brain health | Phytochemicals in foods such as berries, tea, onions, and purple cabbage support brain plasticity, cognition, and help prevent neurodegenerative disorders. |
| Source of antioxidants | Phytochemicals are found in herbs and spices, which offer a variety of colors and some of the highest antioxidant properties. |
| Heart health | Phytochemicals in a plant-based diet can help reduce cholesterol and the risk of heart disease. |
| Nutrient intake | Phytochemicals are found in plant-based foods, which also provide additional nutrients such as fiber, vitamins, and minerals. |
| Variety | A diverse range of plant-based foods should be consumed to obtain various phytochemicals, as no single plant food can provide all the necessary phytochemicals. |

Phytochemicals can help prevent cancer
Phytochemicals are compounds in plant foods that can help prevent chronic diseases like cancer. They are also referred to as phytonutrients. Phytochemicals are not essential for survival, but they do offer impressive health benefits. They are part of a plant's immune system, protecting it from viruses, bacteria, fungi, and parasites. Phytochemicals can offer humans some of the same protections.
Phytochemicals act as chemoprevention, hindering cancer development by preventing DNA damage. They can also repair mutated genes, slow cancer growth, and help abnormal cells die more quickly. They may also prevent carcinogens (cancer-causing agents) from forming.
Indoles and glucosinolates, for example, can help lower your cancer risk. They are known to prevent tumor growth and decrease the production of cancer-related hormones. They can be found in broccoli, cabbage, kale, cauliflower, and Brussels sprouts.
Ellagic acid and resveratrol are two types of polyphenols that can prevent cancer formation and inflammation. They are typically found in green tea, grapes, wine, berries, citrus fruits, apples, whole grains, and peanuts.
The American Institute for Cancer Research recommends eating a mostly plant-based diet for cancer prevention. Eating a variety of vegetables and fruits is key, as the type and amount of phytochemicals vary across different plants.

They can also protect against other chronic diseases
Phytochemicals are compounds in plant foods that can help prevent chronic diseases. They are part of the plant's immune system and help protect it from viruses, bacteria, fungi, and parasites. Phytochemicals can offer humans some of the same protections. While they are not necessary for survival, they protect your cells from damage caused by environmental toxins and the body's natural metabolic processes.
Phytochemicals act as chemoprevention, hindering cancer development by preventing DNA damage. They can also repair mutated genes, slow cancer growth, and help abnormal cells die more quickly. Research supports using phytochemicals as chemoprevention for several types of cancer. For example, ellagic acid and resveratrol are two types of polyphenols that can prevent cancer formation and inflammation. They are typically found in green tea, grapes, wine, berries, citrus fruits, apples, whole grains, and peanuts.
In addition to cancer, phytochemicals may help prevent other chronic diseases, including cardiovascular disease, diabetes, and obesity. Phytochemicals can help reduce cholesterol and cardiovascular disease. People who eat more vegetables have improved survival rates for heart disease and certain cancers.
The best way to ensure you're getting a variety of phytochemicals is to eat a rainbow of plant-based foods. The fruits and vegetables with deeper and brighter colours or stronger flavours are often the best sources of phytochemicals. Larger concentrations of phytochemicals are also often found in the skins or peels of fruits and vegetables.
It's important to note that there is no single vital food ingredient, herb, or nutrient that you need to include in your diet for great health benefits. Instead, the key is to get phytochemicals from whole foods, not supplements, and to eat a variety of plant foods to get the most protection.

They can be found in a variety of plant-based foods
Phytochemicals are compounds found in plant-based foods. They are also known as phytonutrients and are part of a plant's immune system, protecting it from viruses, bacteria, fungi, and parasites. While they are not essential for human survival, they do offer a host of health benefits.
Phytochemicals can be found in a variety of plant-based foods, including fruits, vegetables, beans, grains, nuts, and seeds. The type and amount of phytochemicals vary depending on the plant. For example, there are over 100 phytochemicals in a single carrot! Brightly coloured fruits and vegetables, such as carrots, often contain higher concentrations of phytochemicals, which can also be found in the skins and peels of produce.
Some specific plant-based foods that contain phytochemicals include berries, tea, onions, purple cabbage, green tea, grapes, apples, whole grains, and peanuts. Even white foods like onions and garlic contain phytochemicals, although they are not as brightly coloured. Herbs and spices are also a great source of phytochemicals and can easily be added to meals to boost flavour and phytochemical intake.
By eating a variety of plant-based foods, you can increase your intake of phytochemicals and potentially gain health benefits.

Phytochemicals give foods their colour and smell
Phytochemicals, also called phytonutrients, are compounds found in plant foods. They are part of the plant's immune system and help protect the plant from viruses, bacteria, fungi and parasites.
Phytonutrients give fruits and vegetables their colour and smell. While there are still phytochemicals in white foods such as onions and garlic, deeper and brighter colours or stronger flavours indicate a higher concentration of phytochemicals. Larger concentrations of phytochemicals are also often found in the skins or peels of fruits and vegetables.
To ensure you are getting a variety of phytochemicals in your diet, it is recommended to eat a rainbow of plant-based foods. Phytochemicals can also be found in herbs and spices, which are fragrant and offer a variety of colours.
Phytochemicals have been shown to have health benefits for humans, such as lowering the risk of major chronic diseases including cancer, diabetes, obesity and cardiovascular disease. They act as chemoprevention by hindering cancer development and preventing DNA damage.

They can repair mutated genes and slow cancer growth

They are part of the plant's immune system and help protect the plant from viruses, bacteria, fungi, and parasites. Phytochemicals can offer humans some of the same protections. They act as chemoprevention by hindering cancer development and preventing DNA damage.
Cancer is often the result of changes in more than one type of gene within a cell. For instance, when a proto-oncogene mutates or there are too many copies of it, it can become activated when it is not supposed to be. This can lead to cells growing out of control, which can then result in cancer.
Phytochemicals can repair mutated genes and slow cancer growth. They can also help abnormal cells die more quickly. Research supports using phytochemicals as chemoprevention for several types of cancer. For example, ellagic acid and resveratrol are two types of polyphenols that can prevent cancer formation and inflammation.

Making simple dietary changes to include more phytochemicals provides a safe, cost-effective way to prevent cancer.
