Mangoes and Green Bananas to Prevent Colon Cancer

Two flavored fruits, researchers in Mexico have highlighted the properties of green mangoes and bananas in the prevention of colon cancer.

Mangoes and Green Bananas to Prevent Colon Cancer


Mangoes and green bananas have properties to help prevent colon cancer, according to researchers at Mexico's National Polytechnic Institute (IPN).

These are undoubtedly two fruits with many flavors and great properties, according to the study conducted at the Center for Development of Biotic Products, was found that green mangoes and bananas are a source of starch resistant and function as dietary fiber.

Luis Arturo Bello Perez, who led the research, explained that starch is the main polysaccharide, which when completely disorganized by cooking is hydrolyzed by digestive enzymes to become glucose, which increases the content of this carbohydrate in the blood.

The scientist explained that there is a great variety of cereals, particularly corn, wheat, rice, and some roots and tubers, such as potato, yucca, sweet potato and taro, from which starches used in the food industry are extracted.

However, the study found that mangoes and bananas that are not fully ripe contain a greater amount of resistant starch.

He asserted that in this phase, starch has physiological benefits as a regulator of blood cholesterol and as a contribution of calories necessary for diabetics without exceeding blood sugar.

However, the main quality is that it becomes a protector of the cells that cover the colon and when it reaches the large intestine is fermented by the microbiota, which produces butyrate, a short-chain fatty acid.

The butyrate has anti-inflammatory properties, while providing enough energy for the cells that line the colon, so the greater the presence of this fatty acid there is a better protective effect, particularly in the processes of inflammation of this organ, the researcher abounded.

According to health authorities, in Mexico are diagnosed about 15,000 cases of this type of cancer a year, as well as more than 6,500 patients who lose their lives.

The researcher said it is important to evaluate the methods of processing, storage and production of these fruits to have a higher quality sensory, nutritional and functional.

Derived from the result of his research, Bello Perez has proposed to grant the quality of nutraceuticals (products from foods with nutritional and functional characteristics positive for the body) to resistant starch.

This is because its consumption produces beneficial effects on health, in addition to being of great help in the prevention of obesity and overweight, which are the origin of major global health problems such as cardiovascular disease or diabetes.

Are Milk and Dairy Healthy? Do They Cause Cancer?

Although the health community mostly defends the glass of milk as an example and good practice of a healthy diet and nutritional quality (for example with campaigns such as Get the Glass), the milk and dairy is a food group harshly punished by the new nutritional trends. The lactose intolerance of a good part of human beings has contributed to reinforce this black legend. Or books like "Your life in your hands", written by geochemistry teacher Jane Plant, have fanned the flames against them, as the author thinks she was cured of breast cancer by stopping drinking milk and dairy products.

Are Milk and Dairy Healthy? Do They Cause Cancer


Also the latest trends in the so-called paleolithic diets, especially those more in line with Loren Cordain's guidelines, restrict them significantly, since according to these approaches did not appear in the diet of our ancestors. This argument is usually reinforced by the possible presence of antibiotics or hormones that industry uses on livestock (something that can really be a problem) and by the supposed nutritional degradation that occurs during pasteurization. Specifically, this process in which the product is heated to high temperatures for a very short time in order to eliminate microorganisms, is one of the most criticized, being blamed for a good number of drawbacks that, according to some, surpass its more than interesting sterilizing efficiency.

As you can imagine, for a server the argument "we are the only animal that continues to drink adult milk" is not enough. We are the only animal that does many things, without having to be bad or negative because of it. Although some of the advocates of these anti-dairy theories propose different mechanisms and studies to justify them, the most direct way we have to check if all these fears really make any sense is through epidemiological studies. If dairy products cause breast cancer, we will find a higher prevalence of this disease among women who consume it in greater quantity. Or if its intake affects the cells of our pancreas, the increased incidence of diabetes will also be evident.

Fortunately, extensive reviews and meta-analyses have recently been published on the subject, so we won't have to go study by study because many experts have done so before:

Nutrients


- A systematic review and meta-analysis of the effects of pasteurization on milk vitamins, and evidence for raw milk consumption and other health-related outcomes was published in 2011, in which it was concluded that although the process causes some decrease in the concentration of some vitamins, they are not many nor is it a particularly important reduction. Regarding the consumption of raw milk, the review did not identify solid studies that found neither clear advantages nor disadvantages.

- The publication of "Unpasteurized Milk: A Continued Public Health Threat" (2009) also highlighted the large number of risks involved in consuming unpasteurized milk and the lack of scientific evidence regarding the accusations of nutrient loss after this process. The following table included described in detail how little various nutrients were affected.

Cancer


- In 2011 the meta-analysis "Dairy consumption and risk of breast cancer: a meta-analysis of prospective cohort studies" was published, reviewing studies on breast and dairy cancer and concluded that higher consumption correlates with lower incidence of this type of cancer (inverse relationship).

- In 2012 in the meta-analysis "Dairy products and colorectal cancer risk: a systematic review and meta-analysis of cohort studies" the researchers also concluded that a higher total consumption of dairy and milk was associated with a lower rate of colorectal cancer. The 2004 study "Dairy foods, calcium, and colorectal cancer: a pooled analysis of 10 cohort studies" reached similar conclusions.

The 2008 meta-analysis "Dairy products, dietary calcium and vitamin D intake as risk factors for prostate cancer: a meta-analysis of 26,769 cases from 45 observational studies" also found no correlation between dairy consumption and prostate cancer. On the other hand, the global review Evaluating the links between intake of milk/dairy products and cancer published in 2012 analyzed the studies that have investigated during the last years the relationship between dairy and cancers of the gallbladder, prostate, breast and colon. The authors found no clear evidence of any association with prostate cancer and found an inverse relationship (more dairy - less cancer) in the rest.

- The research "Milk and dairy consumption and risk of bladder cancer: a meta-analysis" (2011) found no solid scientific evidence associating the consumption of milk or dairy products with gallbladder cancer.

Diabetes


- In the 2009 article "Milk products, insulin resistance syndrome and type 2 diabetes" the inverse correlation (more dairy - less diabetes) between dairy consumption and diabetes and the metabolic syndrome was highlighted and references from studies confirming this were included. Similar conclusions were reached in the 2010 review "The consumption of milk and dairy foods and the incidence of vascular disease and diabetes: an overview of the evidence".

- Similarly, in the 2012 review of which we spoke in an earlier article "The relationship between high-fat dairy consumption and obesity, cardiovascular, and metabolic disease" in the different included studies no relationship was found between dairy and diabetes, or the one found was an inverse relationship.

Mortality and Other Diseases


- These are the meta-analyses on cardiovascular diseases, all of them with favourable or neutral results for dairy products:
- In 2015 the meta-analysis "Dairy products consumption and metabolic syndrome in adults: systematic review and meta-analysis of observational studies" concluded that higher dairy consumption was associated with lower risk of metabolic syndrome.

- The review A systematic review and meta-analysis of elevated blood pressure and consumption of dairy foods" (2012) concluded that higher consumption of skimmed dairy products is associated with lower blood pressure and that whole dairy products have no association with this pathology.

- The 2008 meta-analysis "The survival advantage of milk and dairy consumption: an overview of evidence from cohort studies of vascular diseases, diabetes and cancer" analyzing studies that investigated the correlation between dairy and mortality in relation to cardiovascular disease, diabetes and cancer, concluded that there is a correlation between increased survival and increased dairy intake.

Conclusion: Dairy products are associated with better health and lower mortality


It seems to me that the evidence is strong. If you do not have any kind of intolerance, dairy and milk do not seem to be bad at all, quite the contrary, your usual consumption has a lot of benefits and the most reasonable decision is to take them after pasteurization. The hypotheses and theories against them may be interesting or sound good, but for the moment the epidemiology contradicts them categorically.

However, drink milk, cheese and yogurt as naturally as possible and avoid added sugars and high processing, which result in products more similar to soft drinks or sweets than real food. A drinkable one of those given to children at snack time is much less recommended than a normal glass of milk. And even a glass of water.

It is true that much of the research on dairy products has been funded by industry, but there are also many independent studies and the review "Relationship between funding sources and outcomes of obesity-related research" (2012) found no evidence that there were differences between the results depending on their funding.

Aspirin May Reduce Risk of Ovarian Cancer

Although more studies are needed, there is a very close and beneficial association between women taking low doses of this drug.

Aspirin May Reduce Risk of Ovarian Cancer


Regular use of low-dose aspirin may reduce the risk of ovarian cancer, a new study suggests. Researchers analyzed data from more than 205,000 American women, and found that those who reported recent and regular use of low-dose aspirin (defined as 100 milligrams or less) had a 23 percent lower risk of developing ovarian cancer than those who did not take aspirin regularly.

The risk wasn't reduced the longer women used low-dose aspirin. The study also failed to prove that aspirin reduced the risk of cancer, only that there was an association. And taking standard-dose aspirin (325 milligrams) was not associated with a lower risk of ovarian cancer.

On the other hand, taking 10 or more non-steroidal anti-inflammatory drug (NSAID) tablets per week that were not aspirin, such as ibuprofen or naproxen, for several years was associated with an increased risk of ovarian cancer, the study authors noted.

"What really differentiated this study from previous work was that we were able to analyze low-dose aspirin separately from standard-dose aspirin," said study leader Mollie Barnard, who conducted the research while a doctoral student at Harvard University's T.H. Chan School of Public Health.

"Our findings emphasize that research on aspirin use and cancer risk should take into account the dose of aspirin," he added in a Harvard news release.

Barnard is currently a postdoctoral fellow at the Huntsman Cancer Institute at the University of Utah.

Ovarian cancer is the fifth leading cause of cancer death among women in the United States. There is growing evidence that inflammation plays a role in the development of that cancer. It is believed that aspirin may reduce the risk of ovarian cancer by reducing inflammation.

"More research is needed to find out which women can get the most benefit from taking low-dose aspirin to reduce their risk of ovarian cancer," study author Shelley Tworoger, an associate professor of population sciences at Moffitt Cancer Center in Tampa, Fla., said in the news release. Moffitt scientists participated in the study.

13 Foods That Can Prevent Cancer - Based on Studies

What you eat can drastically affect many aspects of your health, including the risk of developing chronic diseases, such as heart disease, diabetes and cancer.

13 Foods That Can Prevent Cancer - Based on Studies


Many studies have shown that the development of cancer, in particular, is closely related to the foods you eat.

It is no secret to anyone that many foods contain beneficial compounds that may help slow the development of cancer.

There are also several studies that show that a higher intake of certain foods may be associated with a lower risk of the condition.

This article will explore and analyze 13 foods that may reduce the development of cancer based on studies.

1. Carrots

Carrots


Can the carrot prevent the development of cancer?


Several studies have found that including carrots in the daily diet is associated with a lower risk of certain cancers.

For example, research analyzed the results of five studies and concluded that eating carrots can reduce the risk of stomach cancer by up to 26%.

Another study found that a higher intake of carrots was associated with an 18% lower chance of developing prostate cancer.

One study looked at the diets of 1,266 participants with and without lung cancer. It found that current smokers who didn't eat carrots today were three times more likely to develop lung cancer, compared to participants who ate carrots more than once a week.

Try adding carrots to your diet as a healthy snack or a delicious side dish a few times a week to potentially reduce your risk of cancer.

Still, remember that these studies show a link between carrot consumption and cancer, but do not take into account other factors that may play a role.

2. Broccoli

Broccoli


Can broccoli prevent the development of cancer?


Broccoli contains sulforaphane, a plant compound found in cruciferous vegetables that can have potent anti-cancer properties.

Including broccoli as an accompaniment in some meals on a weekly basis can give you some cancer-fighting benefits.

A study of test tubes showed that sulforaphane reduced the size and number of breast cancer cells by up to 75%.

Similarly, an animal study found that treating mice with sulforaphane helped eliminate prostate cancer cells and reduced tumor volume by more than 50%.

Some studies have also found that increased consumption of cruciferous vegetables, such as broccoli, may be associated with a lower risk of colorectal cancer.

However, it should be noted that available research has not directly analyzed the effects of broccoli on the development of cancer in humans.

Rather, it has been limited to laboratory, animal, and observational studies, which investigated the effects of cruciferous vegetables or the effects of a specific compound on broccoli, so more studies are needed.

3. Beans

Can beans prevent the development of cancer?


Beans are rich in fiber, which, according to some studies, can help protect against colorectal cancer.

In fact, several studies have found that higher bean intake may reduce the risk of the condition.

One study followed 1,905 people with a history of colorectal tumors and found that those who consumed more cooked dry beans tended to have a lower risk of tumor recurrence.

An animal study also found that feeding mice black beans or white beans, after inducing colon cancer, blocked the development of cancer cells by up to 75%.

According to these results, eating a few servings of beans each week can increase your fiber intake, and in turn help reduce your risk of developing cancer.

However, current research is limited to animal studies and studies that show association, but not causation. More studies are needed to examine this in humans specifically.

4. Berries

Berries


Do berries help prevent the development of cancer?


The berries have a high anthocyanin content, are plant pigments that have antioxidant properties and may be associated with a lower risk of developing cancer.

In one study, 25 people with colorectal cancer were treated with cranberry extract for seven days, this reduced the growth of cancer cells by 7%.

Another small study administered freeze-dried black raspberries (a process in which they are frozen and thawed, kept under vacuum and at low atmospheric pressure) to patients with oral cancer, and showed that it reduced the levels of certain markers associated with the development of cancer.

An animal study found that feeding freeze-dried black raspberries to mice reduced the formation of esophageal tumors by up to 54% and decreased the number of tumors overall by up to 62%.

Similarly, another animal study showed that by giving mice a berry extract, they were found to prevent the formation of several cancer biomarkers.

Based on these findings, including a portion or two of berries in your diet every day can help inhibit the development of cancer.

It is important to note that these studies have been conducted in animals, and are observational, which only analyze the effects of a concentrated dose of berry extract. More research is needed on people.

5. Cinnamon

Can cinnamon prevent the development of cancer?


Cinnamon is very popular for its health benefits, it can lower blood sugar and relieve inflammation, and has been shown in studies to prevent the development of cancer by mitigating cancer cells.

Studies in test tubes and animals have found that cinnamon can help block the spread of cancer cells.

A test tube study found that cinnamon extract could decrease the spread of cancer cells by causing their mitigation.

Another test tube study showed that cinnamon essential oil suppressed the growth of cancer cells in the head and neck, and also significantly reduced tumor size.

An animal study also showed that cinnamon extract promotes the elimination of tumor cells, and also reduces the number of tumors that grow and spread.

Including half a teaspoon or a teaspoon (2-4 grams) of cinnamon in your diet per day may be beneficial in preventing cancer, and may also provide other benefits.

It is important to note that you should keep the amount of cinnamon you consume under control, as too much cinnamon can cause certain side effects.

However, more studies are needed to understand how cinnamon can affect the development of cancer in humans.

6. Nuts and dried fruit

Nuts


Can nuts prevent the development of cancer?


Several studies have found that eating nuts and dried fruit may be related to a lower risk of certain types of cancer.

For example, one study analyzed the diets of 19,386 people, finding that eating more nuts and dried fruit was associated with a lower risk of cancer death.

Another study followed 30,708 participants for up to 30 years, finding that eating nuts regularly was associated with minimal risk of colorectal, pancreatic and endometrial cancer.

Other studies have found that certain nuts are probably even more efficient at preventing the development of cancer.

For example, Brazil nuts are high in selenium, which can help protect against lung cancer in people with low selenium.

Similarly, an animal study showed that feeding mice nuts, decreased the rate of spread of breast cancer cells by 80% and reduced the number of tumors by 60%.

These results suggest that adding a serving of nuts and dried fruit to your diet every day may reduce your risk of developing cancer in the future.

However, more human studies are needed to conclude whether nuts themselves are responsible for this association, or whether other factors are involved.

7. Olive oil

Does olive oil help to prevent the development of cancer?


Olive oil is loaded with health benefits, so it is not surprising that it is one of the staple foods of the Mediterranean diet; several studies have found that higher olive oil intake can help protect against various types of cancer, although more research is needed.

A massive review of 19 studies showed that people who consumed a higher amount of olive oil had a lower risk of developing breast cancer and cancer of the digestive system compared to people who had a lower intake.

Another study that analyzed cancer rates in 28 countries worldwide found that areas with a higher intake of olive oil had lower rates of colorectal cancer.

Exchanging other oils for olive oil in your diet is a simple way to take advantage of its health benefits. You can sprinkle it on salads and cooked vegetables, or try using it on marinades of meat, fish or chicken.

Although these studies show that there may be an association between olive oil intake and cancer, other factors may also be involved. More studies are needed to examine the direct effects of olive oil on cancer in people.


8. Turmeric

Turmeric


Does turmeric prevent the development of cancer?


Turmeric is a spice known for its health-enhancing properties. Curcumin, its active ingredient, is a chemical with anti-inflammatory, antioxidant and even anti-cancer effects.

One study looked at the effects of curcumin in 44 patients with lesions in the colon that might have become cancerous. After 30 days, 4 grams of curcumin per day reduced the number of lesions present by 40%.

In a test tube study, it was found that curcumin also decreases the spread of colon cancer cells by targeting a specific enzyme related to the development of cancer.

Another test tube study showed that curcumin helped kill cancer cells in the head and neck.

Curcumin has also been shown in other test tube studies to be effective in slowing the growth of lung, breast and prostate cancer cells.

For best results, you can include at least three teaspoons (1-3 grams) of ground turmeric per day. It is recommended to use it as a spice to add flavor to food, combining it with black pepper can help to increase its flavor.



9. Citrus fruits

Citrus fruits


Can citrus fruits prevent the development of cancer?


Several studies suggest that eating citrus fruits such as lemons, limes, grapefruits, and oranges has been associated with a lower risk of cancer.

One large study found that participants who ate more citrus fruits had a lower risk of developing cancers of the digestive tract and upper respiratory tract.

On the other hand, a review of nine studies found that higher citrus intake was associated with a lower risk of pancreatic cancer.

Finally, a review of 14 studies showed that high intake (or at least three servings per week) of citrus fruits reduced the risk of stomach cancer by 28%.

These studies suggest that including a few servings of citrus fruits in your diet each week may reduce your risk of developing certain types of cancer.

It should be noted that these studies do not take into account other factors that may be involved. More studies are needed to know specifically how citrus fruits affect the development of cancer.

10. Flaxseed

Flaxseed


Can flaxseed prevent the development of cancer?


Flaxseed is high in fiber and heart-healthy fats, according to studies, flaxseed helps prevent the development of colorectal cancer and mitigate cancer cells; including flaxseed in your diet can have healthy results.

In one study, 32 women with breast cancer received a flaxseed roll per day or placebo for more than a month.

At the end of the study, the flaxseed group showed a decrease in levels of specific markers linked to tumor growth, as well as a reduction in the number of cancer cells.

In another study, 161 men with prostate cancer were treated with flaxseed, which reduced both the growth of the cancer and the number of cancer cells.

Flaxseed is rich in fiber, and other studies have shown it helps protect against colorectal cancer.

You can try adding a tablespoon (10 grams) of ground flaxseed to your diet each day, mixing it in shakes, sprinkling it over cereal and yogurt, or adding it to your favorite baked desserts.

11. Tomatoes

Tomatoes


Do tomatoes prevent the development of cancer?


The tomatoes are full of many nutrients, they also have lycopene, a compound that attributes the vibrant red color to tomatoes, its greatest benefit is that it has anti-cancer properties.

Several studies have found that higher intake of tomatoes, regardless of their presentation, whether raw, in sauce, or as you wish, may reduce the risk of prostate cancer.

To increase your intake of tomatoes in your diet, you can add them to sandwiches, salads, sauces or pasta dishes.

Still, remember that these studies show that there may be an association between eating tomatoes and reducing your risk of prostate cancer, but they do not take into account other factors that may be involved.

12. Oily fish

Mackerel


Does oily fish prevent the development of cancer?


Oily fish, unlike other types of meat, gives you large amounts of Vitamin D and Omega-3 fatty acids, nutrients that are believed to be responsible for the properties of fatty fish to prevent the development of cancer.

A large study showed that higher fish intake was associated with a lower risk of digestive tract cancer.

Another study, which followed 478,040 adults, found that eating more fish reduced the risk of developing colorectal cancer, while red and processed meats increased the risk of developing colorectal cancer.

In particular, fatty fish such as salmon, mackerel and anchovies contain important nutrients such as vitamin D and omega-3 fatty acids that have been linked to a lower risk of cancer.

For example, having adequate levels of vitamin D is believed to protect against and reduce the risk of cancer.

Similarly, omega-3 fatty acids are thought to block the development of the disease.

You can take two servings of fatty fish per week to get a hearty dose of omega-3 fatty acids and vitamin D to maximize the potential health benefits of these nutrients.

Still, more research is needed to determine how consumption of fatty fish can directly influence cancer risk in humans.

12. Garlic

Garlic


Can garlic prevent the development of cancer?


Garlic has many health benefits for you. The active component in garlic is allicin, which has been shown in multiple test tube studies to kill cancer cells.

Several studies have found an association between garlic consumption and a lower risk of certain types of cancer.

A study of 543,220 participants found that those who ate many Allium vegetables, such as garlic, onions and others, had a lower risk of stomach cancer than those who rarely ate them.

A study of 471 men showed that a higher intake of garlic was associated with a lower risk of prostate cancer.

Another study found that participants who ate a lot of garlic, as well as fruits and vegetables, were less likely to develop colorectal tumors. However, this study did not isolate the effects of garlic.

Based on these findings, including 2 to 5 grams (approximately one clove) of fresh garlic in your daily diet can help you take advantage of its health-promoting properties.

However, despite promising results showing an association between garlic and a lower risk of cancer, more studies are needed to examine whether other factors play a role.

In conclusion

As new research emerges, it becomes increasingly clear that your health depends primarily on what you eat, including the risks of cancer.

Although there are many foods that have the potential to reduce the spread and development of cancer cells, current research is limited to laboratory, observational, and test tube studies.

More studies are needed to understand how these foods can directly affect the development of cancer in humans.

In the meantime, it is a sure thing that a diet rich in whole foods, along with a healthy lifestyle, will improve many aspects of your overall health.
