The Role of Diet in Cancer Prevention and Risk Reduction

In the Certificate in Nutrition and Cancer Care, there are several key terms and vocabulary related to the role of diet in cancer prevention and risk reduction that are important to understand. Here, we will explore these terms in detail, providing examples, practical applications, and challenges to deepen your understanding.

Cancer: a group of diseases characterized by the uncontrolled growth and spread of abnormal cells.

Diet: the foods and drinks that a person consumes on a regular basis.

Cancer prevention: actions taken to reduce the risk of developing cancer.

Cancer risk reduction: decreasing the likelihood of cancer recurrence or progression in individuals with a history of cancer.

Nutrition: the process of providing or obtaining the food necessary for health and growth.

Phytochemicals: compounds found in plants that have potential health benefits, including cancer prevention. Examples include carotenoids, flavonoids, and isothiocyanates.

Carotenoids: pigments found in fruits and vegetables that have antioxidant properties and may reduce the risk of certain cancers. Examples include beta-carotene, lycopene, and lutein.

Flavonoids: a class of phytochemicals found in fruits, vegetables, and tea that have anti-inflammatory and antioxidant properties and may reduce the risk of certain cancers.

Isothiocyanates: phytochemicals found in cruciferous vegetables (e.g., broccoli, Brussels sprouts, and cabbage) that have been shown to have anti-cancer properties.

Antioxidants: compounds that protect cells from damage caused by free radicals, which are unstable molecules that can damage DNA and contribute to the development of cancer.

Free radicals: unstable molecules that can damage cells and contribute to the development of cancer.

Oxidative stress: an imbalance between the production of free radicals and the body's ability to neutralize them, which can lead to cell damage and contribute to the development of cancer.

Fiber: the indigestible part of plant foods that helps to regulate digestion and may reduce the risk of certain cancers.

Obesity: a condition characterized by an excess amount of body fat, which has been linked to an increased risk of several types of cancer.

Physical activity: any bodily movement produced by skeletal muscles that requires energy expenditure, which has been shown to reduce the risk of several types of cancer.

Inflammation: the body's response to injury or infection, which can contribute to the development of cancer.

Gut microbiome: the community of microorganisms that live in the gut, which has been linked to the development of cancer.

Probiotics: live bacteria and yeasts that are beneficial for health, particularly the digestive system, and may reduce the risk of certain cancers.

Prebiotics: non-digestible food ingredients that promote the growth of beneficial bacteria in the gut, which may reduce the risk of certain cancers.

Fermented foods: foods that have been through a process of lactofermentation, in which natural bacteria feed on the sugars and starches in the food, creating lactic acid and probiotics, which may reduce the risk of certain cancers.

Polyphenols: a class of phytochemicals found in fruits, vegetables, and tea that have anti-inflammatory and antioxidant properties and may reduce the risk of certain cancers.

Organic foods: foods that are produced without the use of synthetic pesticides, fertilizers, genetically modified organisms, irradiation, and sewage sludge.

Genetic predisposition: a person's susceptibility to a particular disease based on their genetic makeup.

Epigenetics: the study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself.

Biomarkers: a measurable indicator of the severity or presence of some disease state.

Mediterranean diet: a dietary pattern characterized by high consumption of fruits, vegetables, whole grains, legumes, and healthy fats, such as olive oil, and low consumption of red and processed meats, dairy products, and sweets.

DASH diet: a dietary pattern characterized by high consumption of fruits, vegetables, whole grains, and low-fat dairy products, and low consumption of saturated fats, cholesterol, and sodium.

Intermittent fasting: a dietary approach that involves cycling between periods of eating and fasting.

Caloric restriction: a dietary approach that involves reducing daily caloric intake without causing malnutrition.

Apoptosis: programmed cell death, which is a normal process that helps to get rid of damaged or abnormal cells and prevent the development of cancer.

Angiogenesis: the process of forming new blood vessels, which is necessary for the growth and spread of cancer.

Metastasis: the spread of cancer from one part of the body to another.

Cruciferous vegetables: vegetables that belong to the Brassicaceae family, such as broccoli, Brussels sprouts, and cabbage, which have been shown to have anti-cancer properties.

Sulforaphane: a phytochemical found in cruciferous vegetables that has been shown to have anti-cancer properties.

Indole-3-carbinol: a phytochemical found in cruciferous vegetables that has been shown to have anti-cancer properties.

Selenium: a mineral found in nuts, grains, and seafood that has been shown to have anti-cancer properties.

Vitamin D: a nutrient that is produced by the body in response to sunlight and is found in certain foods, such as fatty fish and fortified dairy products, that has been shown to have anti-cancer properties.

Curcumin: a phytochemical found in turmeric that has been shown to have anti-inflammatory and anti-cancer properties.

Resveratrol: a phytochemical found in grapes, berries, and peanuts that has been shown to have anti-inflammatory and anti-cancer properties.

Green tea: a type of tea that is made from the leaves of the Camellia sinensis plant and has been shown to have anti-cancer properties.

EGCG: a catechin found in green tea that has been shown to have anti-cancer properties.

Soy: a legume that is a rich source of isoflavones, which have been shown to have anti-cancer properties.

Isoflavones: a class of phytochemicals found in soy that have been shown to have anti-cancer properties.

Genistein: an isoflavone found in soy that has been shown to have anti-cancer properties.

Red meat: meat that comes from mammals, such as beef, pork, and lamb, and has been linked to an increased risk of certain cancers.

Processed meat: meat that has been preserved by smoking, curing, salting, or adding preservatives, and has been linked to an increased risk of certain cancers.

Heterocyclic amines: compounds formed when meat is cooked at high temperatures, such as grilling or pan-frying, and have been linked to an increased risk of certain cancers.
