OK here's what I want to know. Say I went out and got strawberry powder, and wanted to do this. Sounds like there's no harm in it and it's very beneficial. How do I know what is 60g worth of strawberries, what size glass of water (regular tap water?)to use etc? Currently I'm juicing with strawberries, not sure if that's the same thing or not. Any ideas from anyone? Thanks for any replies. I'd like to try it.

This makes sense in that strawberries (and berries in general) are rich in anti-oxidants. However this study was lacking in a lot of areas. We know nothing about the diet of the individuals, and the trial size was very small. However, I think you will rarely do poorly, if you eat a diet full of fresh fruits and vegetables.

According to the medical conditions monograph on the Natural Standard website, some factors that increase a person’s risk for developing gastrointestinal cancers, such as esophageal cancer, are smoking, older age, male gender, ethnicity, genetics, and a history of H. pylori infection. Most of these risk factors are not modifiable, which is concerning. It would be great if a product like strawberry powder could help decrease a person’s risk of esophageal cancer. The 60g daily dose of the strawberry powder had significant effects in decreasing the amount of abnormal esophageal cells, but the lower dose did not see these benefits. Since side effects were lacking in this trial, it would be reasonable for studies to try to use higher doses of strawberry powder. It would be interesting to see if higher doses cause an even greater decrease in the risk of esophageal cancer.

How great is it that strawberries may have this beneficial effect. It’s interesting that they would do studies with freeze-dried strawberry powder. It will be good to know when further research is done if ingesting fresh strawberries regularly will have the same beneficial effect or if it needs to be taken as a supplement.

Strawberries have a lot of phytonutrients including terpenoids, anthocyanins, flavonols, ellagitannins, and phenolic acids, which can help with inflammation. Also, when fruits are considered in terms of their antioxidant capacity, strawberries typically rank about 4th among all fruits behind blackberries, cranberries, and raspberries. I wonder if research on these other berries would show cancer reduction as well. The thing about fresh strawberries is that on average, studies show 2 days as the maximal time for strawberry storage without major loss of vitamin C and polyphenol antioxidants. Does freeze-drying strawberries then preserve their nutrients?

This is very interesting. It's amazing how natural, common products such as strawberries can decrease your risk of getting cancer. I also wonder how many strawberries would be equivalent to the 60g of freeze dried strawberry powder that was used in the study.

I never knew that strawberries had all these benefits. I am also interested to see if fresh strawberries and strawberry flavored foods have the same effect. I wonder how the researchers decided on using strawberry powder. It will be interesting to see if the same researchers will conduct other studies with different strawberry food products.

Per Natural Standard’s database in regards to strawberry’s antiproliferative effects, “In in vitro studies, strawberry extract has shown dose-dependent antiproliferative activity, which can vary from cultivar to cultivar (12;​13). Interestingly, one study found that extracts from organically grown strawberries had a higher antiproliferative activity (12).” More information on the freeze dried strawberry powder the study used is important as there are many different varieties of strawberries and other factors that may go into its effects seen on esophageal cancer. I think it is interesting that one study found that organically-grown strawberries had higher antiproliferative activity. Did this study on preventing esophageal cancer use organically grown freeze dried strawberry powder? Perhaps even more of a benefit could be seen if the two were compared, though I do think larger studies in general should be conducted to further explore the possibilities of strawberry in preventing cancer.

I agree that it is interesting that freeze dried strawberry powder was used. I wonder how many strawberries one would have to eat in order to ingest the equivalent of 60g of strawberry powder, and if the raw fruits have an increased efficacy in lowering esophageal cancer risk. I feel that the freeze dried form would have negative effects on the vitamin C and other vitamin levels in the fruit. Overall, interesting study, though more research is certainly warranted.

You always hear in the news and all over the internet about the newest super fruit that is high in antioxidants and vitamins. These trends then start to influence everything from drinks to gums to desert treats. It’s nice to know that even fruit that people are generally very familiar with, like strawberries, has many great health benefits. Strawberries have a Natural Standard evidence grade of B for good scientific evidence as an antioxidant. This is the same grade given to Acai berries, which was one of those berries that was all the craze a couple years ago. I think that all these great health benefits are a really great reflection of how important it is to have a diet full of fresh produce and made up of diverse, vibrant colors. I do feel bad for the people in the study, they had to drink powder instead of being able to enjoy this tasty fruit.

Foods rich in fiber, vitamin C, folate, potassium and antioxidants such as strawberries would be an essential part of a nutritious diet to promote health. It is intereting to find that not only do strawberries have evidence for increasing iron absorption and colorectal cancer, but may have an impact on esophageal cancers as well. It was surprising that the strawberries were freeze dried in the study, as in most cases fruits and vegetables retain the most nutrients in their raw, uncooked, unprocessed ways. Since strawberries are high in antioxidants and have anti-inflammatory effects, I hope that we can see more studies in the future targeting other inflammatory diseases such as rheumatoid arthritis. Since strawberry is a fruit that we normally consume, high safety profile, low cost, and good taste would deem this a good option to keep it in the refrigerator at all times!

This is great news, given how much I love strawberries! I wonder what it is about strawberries that might give them anticancer properties, since lots of fruits are high in fiber, vitamin C, folate, potassium and antioxidants. As fruits go, strawberries are especially high in fiber, but I think that asset may be somewhat lost when using the powdered form of strawberries, especially if it was in capsules. According to Natural Standard, other supplements or foods that may protect against esophageal cancer include greater celandine, PSK, vitamin A (found in things like carrots, sweet potatoes, dark leafy greens, and cantaloupe), beer, glutamine, and spinach (probably due at least partially to its high vitamin A content). I’m not sure what the common link is between all of these and strawberries that might explain their cancer-fighting potential. Either way, you can bet I’ll be checking out some of the strawberry-containing recipes on Natural Standard like the Grilled Stawberry Sandwich or the Strawberry Yogurt Smoothie!

Strawberry powder seems to have the unique combination of antioxidant and anti-inflammatory properties needed to be effective in decreasing esophageal cancer risk. Many patients are at a risk of esophageal cancer, and many of these patients I see in the pharmacy daily are forced to turn to prescription medications to help with these issues. Unfortunately, these medications come with a side effect profile that is not always worth the risk. It is great to see natural options to decrease abnormal esophageal tissue, with no side effects!

Strawberries have been identified as an excellent source of vitamin C, folate, potassium and antioxidants. It is not surprising that consumption may also lessen inflammation and interfere with growth of lesions of the esophagus. It is interesting to note that two doses of different strengths of strawberry powder, not fresh strawberries, were given to patients. Also it is a small randomized study (n=75) of a restricted population in terms of race/ethnicity. Factors such as diet (cultural) and other chronic illnesses were not addressed. The fact that strawberry powder is safe and no adverse side effects were noted helps lead the way to further investigation.
