How do berries prevent cancer

Strawberries are also good sources of antioxidants and folic acid, and are excellent sources of Vitamin C, which has shown to decrease risk for esophageal cancer. In fact, strawberries are a richer source of Vitamin C than oranges!

Raspberries' dark red color comes from flavonoids. These compounds work with fiber to promote health and disease prevention. Ellagic acid, found in raspberries and in other berries is being studied for anti-estrogen properties, especially beneficial for fighting certain breast cancers.

Blackberries , like blueberries, are a great source of anthocyanosides. The other phytochemicals, vitamins and minerals found in blackberries help to strengthen the immune system in order to deactivate free radicals and reduce cancer risk.

While all these components have promise in reducing risk of cancer and promoting a healthy body and immune system, we don't know for sure that it's not something else in the berries, or a combination of things that are doing the most good. There is a unique combination of health promoting chemicals in all plant foods that a pill can never replace.

Berries fight free radicals Our bodies create free radicals through normal processes like digestion. Berries and blood sugar While berries contain naturally-occurring sugar, several studies have found people who consume berries on a regular basis were able to reduce their blood glucose levels and increase their insulin sensitivity, both of which are key for preventing and controlling diabetes.

Beauty benefits of berries A one-cup serving of berries can give you 25 percent of your daily requirement of vitamin C, says Beal. The healthiest ways to eat berries Beal recommends eating a variety of berries to maximize the benefits, as each fruit contains a different amount of each antioxidant.

And remember, not all forms of berries are created equal. Related Stories. Should you try probiotics? Corporate Champions who partner with the American Institute for Cancer Research stand at the forefront of the fight against cancer.

The Continuous Update Project CUP is an ongoing program that analyzes global research on how diet, nutrition and physical activity affect cancer risk and survival. A major milestone in cancer research, the Third Expert Report analyzes and synthesizes the evidence gathered in CUP reports and serves as a vital resource for anyone interested in preventing cancer.

AICR has pushed research to new heights, and has helped thousands of communities better understand the intersection of lifestyle, nutrition, and cancer. Read real-life accounts of how AICR is changing lives through cancer prevention and survivorship.

We bring a detailed policy framework to our advocacy efforts, and provide lawmakers with the scientific evidence they need to achieve our objectives.

AICR champions research that increases understanding of the relationship between nutrition, lifestyle, and cancer. AICR is committed to putting what we know about cancer prevention into action. Blueberries contain many phytochemicals and nutrients which show potential anti-cancer effects in laboratory studies. Several studies found that eating blueberries increases antioxidant activity in the blood as well as showing potential to prevent DNA damage.

The research must include quality human studies that meet specific criteria and biological explanations for the findings. Anthocyanins influence cell signaling in ways that increase antioxidant, anti-inflammatory and carcinogen-deactivating enzymes in cell and animal studies. Flavonols and flavanols influence gene expression and cell signaling in ways that increase antioxidant, anti-inflammatory and carcinogen-deactivating enzymes in cell and animal studies. Flavones influence gene expression and cell signaling in ways that increase antioxidant, anti-inflammatory and carcinogen-deactivating enzymes in cell and animal studies.

They reduce expression of oncogenes genes that have potential to cause increased cell growth that can lead to cancer and increase expression of tumor suppressor genes. Tannins such as ellagitannins and proanthocyanidins are complex compounds that are mostly unabsorbed. Microbes in the gut break them down to form other phytochemicals. In animal studies, blueberries decrease inflammatory cytokines, esophageal cancer and pre-cancerous changes in the colon, although impact on colon cancer is less clear.

In other animal studies, blueberries decreased estrogen-induced mammary cancer and DNA damage. Human studies related to blueberries and cancer risk compare groups of people who consume relatively high and low amounts of total fruit, dietary fiber, berries, or blueberries specifically. People who eat more fruits have a lower risk of a wide range of cancers. This probably reflects combined protection from many different nutrients and compounds they contain.

Dietary Fiber: Observational population studies link high dietary fiber consumption with reduced risk of colorectal cancer. One meta-analysis of 16 prospective studies also links dietary fiber with lower risk of breast cancer.

Vitamin C: Population studies comparing people with higher and lower levels of vitamin C in their diets, and especially levels circulating in their blood, link higher amounts with lower overall risk of cancer. This effect is larger when comparing people with very low levels to moderately increased levels than comparing people with moderate and much higher levels. Higher levels of vitamin C from foods are linked with lower risk of lung cancer among people who smoke tobacco, although not in those who used to smoke or who have never smoked.

People with more vitamin C in their diet are also less likely to develop colon cancer. Ellagitannins and urolithins: Bacteria in the colon convert ellagitannins from blueberries and other berries to ellagic acid and then to urolithins that can be absorbed.

People differ dramatically in the amount and types of urolithins they produce from ellagic acid, which could cause differences in the benefits people get from these foods. Flavonoids found in blueberries: Higher levels of anthocyanins in the diet were strongly associated with lower levels of markers of inflammation, and flavonols and flavanols were linked with lower levels of oxidative stress in cross-sectional analysis of a large population study.

But studies are limited and results vary, so more research is needed. Smoothies have many benefits beyond good taste; they can help you eat more fruits and vegetables, the foundation of a cancer-protective diet This light and delicious walnut snack is the perfect way to keep both kids and adults alike happy and healthy!

Frozen fruit—harvested ripe and frozen quickly—is packed with vitamins, minerals and phytochemicals. No wonder diets rich in fruits fresh, AICR has led the charge in cancer prevention and survivorship for over 30 years. Stay in the loop on the latest AICR cancer research.

Eat Regularly. The Cancer Research Blueberries contain many phytochemicals and nutrients which show potential anti-cancer effects in laboratory studies. A convincing or probable judgement is strong enough to justify recommendations.

In cell studies, proanthocyanidins are antioxidants that seem to influence gene expression to decrease growth of cancer cells and increase their self-destruction.

However, this may not reflect effects when they are consumed in food, especially in parts of the body other than the gut. Ellagitannins are broken down in the digestive system to ellagic acid and then to urolithins, which are the compounds that can be absorbed into the body. In cell and animal studies, ellagic acid and the urolithins that form from it increase antioxidant enzymes, decreasing free radical damage to DNA that can lead to cancer.
