Question on anthocyanins and raspberries?

[nao57]

So... because of the thread I'd asked yesterday this led me to research Anthocyanins a little bit. Anthocyanins are one of the things used to treat kidney problems. They are also used to treat gout, it seems. I'm not an expert on either. But the other day I posted how a family member needed sour cherries to treat their kidney issues. When we dug a bit further it was 2 parts; low potassium foods, AND anthocyanins.

I feel like mentioning this could help others here. AND it lets me post some questions.

First, when I google searched anthocyanin levels in raspberry plants I couldn't get a list. I'd hoped to get a breakdown because there are many types of raspberry plants. And we have everbearing raspberry plants. But I'd worried if all raspberry plants, including everbearing types if they have similar rankings as each other in levels of Anthocyanins? This was my first question. And curious if anyone else here has information on that or if they'd had similar issues with researching treating kidney and other problems with anthocyanins?

Here are some links;

Everbearing raspberries include: Anne, Autumn Bliss, Brandywine, Caroline, Crimson Giant, Crimson Night, Double Gold, Fall Gold, Heritage, Joan J, Niwot, Polana, Prelude, & Sweet Repeat. Dates for 1st & 2nd harvest differs between varieties, so you can choose a few to get berries for months in row!

Top 25 Anthocyanin Rich Superfoods And Why You Should Eat Them

I can't say I've grown that many things on either of those lists. I've grown double gold everbearing raspberries which produce a pink raspberry (it looks gold until it matures). They do work to produce well as long as you don't deplete the soil from lack of fertilizer. (IF anyone wants to try those. I thought it would help to know. I haven't grown other raspberry types yet, and don't need to.)

I'm a little bit worried about if non-red type raspberries have adequate anthocyanin levels also? (And I couldn't find any information on this. Although some articles I listened to on Youtube claimed pink fruits can have anthocyanins also.) And even many vegetables have anthocyanins.

Well... thank you for any feedback you might have. Which I hope for.

Thank you for the information friend. Very interesting and helpfu.

Thanks, this is very interesting, I didn't now about this. I did a little bit of research, though. Based on that link you provided, it sounds like, if you have the space, Blue (Purple) Corn and Black Raspberries might be among the highest in Anthocyanins of things to grow. Also, that way you get one fruit and one vegetable, which can be eaten in different meals at different times.

Just be sure to steam the corn instead of boiling it to retain the most anthocyanins (or keep and re-use the water if you do boil it):

https://www.sciencedirect.com/science/article/abs/pii/S0308814614007754

And products derived from purple corn don't have the same anthocyanins due to the cooking and production process. But, some products do retain anthocyanins better than others (apparently it depends on how they are cooked / the type of oven: https://pubmed.ncbi.nlm.nih.gov/20848670/).

Black Raspberries definitely have anti-cancer properties:

Anthocyanins in Black Raspberries Prevent Esophageal Tumors in Rats - PMC

Diets containing freeze-dried black raspberries (BRB) suppress the development of N-nitrosomethylbenzylamine (NMBA)–induced tumors in the rat esophagus. Using bioassay-directed fractionation, the anthocyanins in BRB were found to be the most active ...

pmc.ncbi.nlm.nih.gov

Sounds like the colour often reflects the amounts of anthocynanins (https://link.springer.com/article/10.1007/s002170050371), so maybe pink raspberries have a bit less?

And blueberries sound like a good go-to food for anthocyanins. Elderberries are even higher in them, apparently, but I don't know how they taste. And it sounds like frozen berries aren't much lower in anthocyanins, but dried berries are (https://www.researchgate.net/public..._Antioxidant_Effect_After_Drying_and_Freezing, and freeze drying can be okay: https://www.researchgate.net/public..._Antioxidant_Effect_After_Drying_and_Freezing).

Thanks for posting this info! This is very helpful.

Thank you. Also I wanted to especially share credit now with oneeye. Oneeye gave me the original tip of the low potassium that let me move forward to find the other information. I also like your comment gardenstart!
