Welcome to episode 22 of The Cancer Pod.
00:00:02.950 --> 00:00:04.719
Today, we're talking about folate.
00:00:05.049 --> 00:00:05.679
What is it?
00:00:05.969 --> 00:00:07.019
Where does it come from?
00:00:07.230 --> 00:00:08.130
Why do we need it?
00:00:08.320 --> 00:00:09.789
What happens if we don't get enough?
00:00:09.990 --> 00:00:14.259
All this and more on today's episode of The Cancer Pod Supplements.
00:00:14.259 --> 00:00:14.919
1 0 1.
00:00:15.539 --> 00:00:16.010
I'm Dr.
00:00:16.010 --> 00:00:19.469
Tina Kaeser and I like roasted brussel sprouts.
00:00:19.746 --> 00:00:20.347
And I'm Dr.
00:00:20.347 --> 00:00:23.983
Lee Sherman and I like steamed asparagus.
00:00:24.548 --> 00:00:28.059
And we're two naturopathic doctors who practice integrative cancer care,
00:00:28.228 --> 00:00:29.789
but we're not your doctors.
00:00:30.088 --> 00:00:34.439
This is for education, entertainment, and informational purposes only
00:00:34.609 --> 00:00:36.679
do not apply any of this information.
00:00:36.679 --> 00:00:38.899
Without first speaking to your doctor,
00:00:39.034 --> 00:00:44.781
the views and opinions expressed on this podcast by the host and their guests are solely their own
00:00:45.002 --> 00:00:46.142
welcome to the cancer.
00:01:02.432 --> 00:01:03.302
So Tina,
00:01:03.482 --> 00:01:04.112
Yes, Leah.
00:01:04.450 --> 00:01:11.510
What's the deal with folate folic acid, vitamin B nine, so many
00:01:11.510 --> 00:01:12.200
names.
00:01:12.563 --> 00:01:24.194
Yeah, I think it's something that's really confusing, especially because there are people out there writing almost scientifically valid blog pieces, but missing the accuracy
00:01:24.555 --> 00:01:25.394
they're interchanging.
00:01:25.394 --> 00:01:27.165
The, the words around.
00:01:27.375 --> 00:01:27.974
Yes.
00:01:28.215 --> 00:01:29.894
So let's just be really clear.
00:01:30.105 --> 00:01:35.632
Folic acid does not occur in nature folate does.
00:01:36.248 --> 00:01:42.890
So first things first, when we're talking about B9, all of these are considered B9 variations.
00:01:44.650 --> 00:01:46.430
Not to be confused with"benign."
00:01:47.180 --> 00:01:56.219
Right, not to be confused with the"benign." Folic acid and folate are used interchangeably a lot, but they're not the same molecule.
00:01:56.343 --> 00:01:59.884
And so chemically, the compounds are completely different.
00:01:59.884 --> 00:02:02.853
Folic acid is what is used to fortify foods.
00:02:02.914 --> 00:02:07.920
So it's added back after you process a food and pull B-vitamins out of a food.
00:02:08.032 --> 00:02:10.491
Folic acid is what's added back folate-
00:02:10.581 --> 00:02:12.741
And it's also what's used in supplements.
00:02:12.891 --> 00:02:18.532
Often it's what's used in supplements, especially if it's a less high quality supplement.
00:02:18.951 --> 00:02:19.252
Right.
00:02:19.611 --> 00:02:23.122
But it's probably more common in like certain grades.
00:02:23.181 --> 00:02:26.062
Higher grade supplements folate is used.
00:02:26.878 --> 00:02:29.478
The common over the counter shelf stuff.
00:02:29.508 --> 00:02:31.397
You're mostly going to see folic acid.
00:02:31.698 --> 00:02:32.268
Yes.
00:02:32.298 --> 00:02:36.467
And of course we as always advocate food over supplements anyways,
00:02:36.628 --> 00:02:37.199
right
00:02:37.288 --> 00:02:40.864
And folate, which is found in food, can be gone from the diet.
00:02:40.864 --> 00:02:42.544
You can get plenty of full, late from the.
00:02:43.338 --> 00:02:45.588
How much someone needs depends on that person.
00:02:45.618 --> 00:02:45.949
Right?
00:02:46.338 --> 00:02:50.159
A pregnant woman, needs more folate than someone who's not going to be carrying a baby.
00:02:50.159 --> 00:02:54.318
For example, um, folic acid is absorbed more readily.
00:02:55.383 --> 00:02:57.453
ate and it's more stable.
00:02:57.483 --> 00:02:59.703
That's why they put it into supplements, that's why they put it into food.
00:03:00.052 --> 00:03:02.133
Folate degrades more quickly.
00:03:02.552 --> 00:03:10.203
So you need the plant cell wall to keep it inside the plant cell and the folate doesn't degrade until the actual food stuff, degrades.
00:03:10.568 --> 00:03:14.169
But as long as it's inside the plant cell wall, it's fairly stable.
00:03:14.618 --> 00:03:16.688
And once you pull it out of there, like.
00:03:17.437 --> 00:03:18.758
Cook your food and left on the counter.
00:03:18.907 --> 00:03:19.657
It's going to degrade.
00:03:19.897 --> 00:03:21.277
So folate is very fragile.
00:03:21.497 --> 00:03:23.837
So it comes from green leafy vegetables.
00:03:24.918 --> 00:03:30.264
Um, so like your asparagus, your broccoli or kale, your, you know, anything that's green.
00:03:31.004 --> 00:03:36.838
And so using those as fresh as possible, you're guaranteeing to get a decent folate level.
00:03:36.838 --> 00:03:41.455
So like the wilted chard that's in my fridge that's been there for two weeks.
00:03:41.860 --> 00:03:43.781
Probably doesn't have the best levels.
00:03:44.110 --> 00:03:44.591
I'm guessing.
00:03:44.860 --> 00:03:45.401
You're right.
00:03:45.461 --> 00:03:45.941
You're right.
00:03:45.971 --> 00:03:58.859
And this goes back to that thing that we've talked about before, which is when you cook vegetables, if you are cooking them in any way and however you do it, steam it stir fry it, whatever the brightness signifies the most bioavailable moment.
00:03:59.188 --> 00:04:08.489
You know, when we eat a plant, if we can see the broccoli is really bright green, that's when you've broken open those cell walls, the plant cell walls, and you're looking right at the chlorophyll.
00:04:08.489 --> 00:04:11.188
So it seems brighter than it did when it was raw, for example.
00:04:11.459 --> 00:04:14.935
And if you keep cooking it, it's going to get more and more gray really.
00:04:15.034 --> 00:04:28.528
So when you see like things of like different levels of full light in food, you'll sometimes see that cooked foods have higher folate content because it's more bioavailable because of steaming or, you know, however you've cooked it until that bright green point.
00:04:28.701 --> 00:04:28.882
Yes.
00:04:28.911 --> 00:04:29.091
Yeah.
00:04:29.091 --> 00:04:32.408
It's kind of one of those things that, isn't mentioned very often right in that is.
00:04:32.949 --> 00:04:39.995
Whenever we talk about nutrients in plants, they're inside the cell wall, which is made of cellulose and you and I can't digest cellulose.
00:04:39.995 --> 00:04:47.995
We have to break it open either by chewing it, cooking it slightly, putting it in a blender, whatever we're going to do, we have to break, open that cell wall to get to the goodies inside.
00:04:48.288 --> 00:04:49.678
That's our cooking tip for today.
00:04:53.880 --> 00:04:56.130
not a big fan of green leafy vegetables.
00:04:56.418 --> 00:05:04.461
You can find folate in beans, peanuts, whole grains, sunflower seeds, seafood, eggs, even liver.
00:05:08.543 --> 00:05:20.312
So for those who have read about this before, you may have come across the term 5- M T H F, which is methyl-tetra-hydro- folate, or 5-methyltetrahydrofolate.
00:05:20.353 --> 00:05:24.069
That is the most active forms of folate within the cell.
00:05:24.069 --> 00:05:30.983
the reason I'm mentioning this is there is anenzyme that some people are getting tested for to see if they even create that within their cells.
00:05:31.194 --> 00:05:33.593
So that's the M T H F R
00:05:34.103 --> 00:05:35.694
The genetic mutation.
00:05:35.723 --> 00:05:36.024
Yeah.
00:05:36.024 --> 00:05:43.096
So the MTHFR is an enzyme and that stands for methylene tetrahydrofolate reductase.
00:05:44.252 --> 00:05:46.262
Which is why we all say MTHFR,
00:05:46.403 --> 00:05:47.454
and that's why you say it.
00:05:47.454 --> 00:05:48.533
And not me.
00:05:50.298 --> 00:05:58.487
And some people are checking whether they got a little glitch, a little, what we call a snip M S N P snip stands for.
00:05:59.177 --> 00:06:01.338
Single nucleotide polymorphism.
00:06:02.117 --> 00:06:03.137
That's it I'm done.
00:06:03.168 --> 00:06:04.697
That's all the big words I'll use today.
00:06:04.697 --> 00:06:05.170
I promise.
00:06:05.718 --> 00:06:15.084
Um, but anyways, those snips, if you got one from mom or one from dad, you may not convert folate, into a usable form as efficiently.
00:06:15.264 --> 00:06:25.014
Then you are going to produce less of this five MTHF, which is the very active form that's needed in the chemical reactions in the body.
00:06:25.014 --> 00:06:30.654
So those people often do better when they take a supplement that contains 5- M T H F
00:06:30.754 --> 00:06:33.394
And you had mentioned when we are offline.
00:06:34.264 --> 00:06:36.964
That actually can degrade quickly too.
00:06:37.235 --> 00:06:37.925
Yes.
00:06:38.014 --> 00:06:38.795
Very volatile.
00:06:38.795 --> 00:06:50.615
So the best supplement companies are putting that the actual active five methyltetrahydrofolic you'll see on the label, five dash M T H F.
00:06:51.214 --> 00:06:53.105
That's the most usable form.
00:06:53.247 --> 00:06:55.648
with the caveat that it degrades quickly.
00:06:56.067 --> 00:07:00.230
And it's not as absorbable as some of the other folates out there.
00:07:00.860 --> 00:07:09.692
So if you have a bottle of, a multivitamin and it has this in it, and it's been sitting on your shelf for five years, maybe get rid of it.
00:07:09.692 --> 00:07:10.802
If it's past the expiration date,
00:07:11.084 --> 00:07:13.454
it's probably going to degrade quickly just like a plant would on your counter
00:07:13.584 --> 00:07:14.694
or if you overcook it.
00:07:14.822 --> 00:07:15.545
Right, right.
00:07:16.593 --> 00:07:27.598
So it's probably good to point out that folic acid, which is found in supplements and in fortified foods, it needs to be converted to folate and that conversion happens in the liver.
00:07:27.598 --> 00:07:30.899
And then it's absorbed in the upper third of the small intestine.
00:07:31.769 --> 00:07:43.637
So that kind of gets like, you know, cancer patients, cancer survivors, thinking in terms of like, if there's any impairment to those parts of your body, there may be a potential for deficiency.
00:07:43.800 --> 00:07:54.314
Deficiencies also can happen with people with a history of alcoholism or just the non-alcoholic fatty liver because of the fact that folate is stored in the,
00:07:54.901 --> 00:08:03.158
and along those lines of who might be deficient as anyone who doesn't have a good, healthy, upper, small intestine, cause both folic acid folate.
00:08:03.187 --> 00:08:04.267
However you're taking it in
00:08:04.324 --> 00:08:04.685
right?
00:08:04.685 --> 00:08:06.995
So like somebody with celiac disease.
00:08:07.084 --> 00:08:13.144
Yeah, because that was a prime example of where the, the Villa, the microvilli of the small intestine are damaged and it's celiac disease.
00:08:13.204 --> 00:08:16.581
And this is one of many nutrient deficiencies that can result.
00:08:16.699 --> 00:08:21.286
So there are also medications that can interfere with, with folate metabolism.
00:08:21.644 --> 00:08:23.744
That are better used in cancer care.
00:08:23.744 --> 00:08:28.427
So like methotrexate is one, pemetrexed, Alimta is another.
00:08:29.418 --> 00:08:40.375
And so sometimes if you're receiving one of those treatments, You may be prescribed a supplement from your doctor, um, because these medications are targeting that.
00:08:40.735 --> 00:08:40.884
Yeah.
00:08:40.914 --> 00:08:42.085
Can I mention right there?
00:08:42.085 --> 00:08:44.043
That's an interesting phenomenon, right?
00:08:44.072 --> 00:08:45.363
So the drugs you just met.
00:08:46.211 --> 00:08:47.681
Actually target the.
00:08:48.806 --> 00:08:49.645
Pathways.
00:08:49.676 --> 00:08:51.566
That's how they stop the cells from dividing.
00:08:51.566 --> 00:08:53.666
That's how they're used in cancer care.
00:08:53.666 --> 00:08:59.275
As anti-cancer agents, a rapidly dividing cell needs to make a lot of DNA, right?
00:08:59.275 --> 00:09:05.605
So as you have a cell dividing over and over, it needs to make a new batch of DNA in the nucleus.
00:09:05.605 --> 00:09:11.816
Every time it does it in what methotrexate and Alimta do is they block that by blocking folate.
00:09:11.905 --> 00:09:17.666
Cause folate is required to make DNA and they give you a form of.
00:09:18.446 --> 00:09:24.655
Folic acid alongside to make sure that there is just enough to rescue your normal cells,
00:09:24.658 --> 00:09:25.018
right.
00:09:25.095 --> 00:09:38.711
So this brings up something reminds me of the fact that every nutrient has what I would call a sweet spot, where you have just enough, not too much, you're not deficient and you're not, megadosing, there's a sweet spot for every single essential nutrient there is.
00:09:39.192 --> 00:09:44.471
And in the case, Benign or folate we should discuss that.
00:09:44.471 --> 00:09:46.475
That what's a deficiency in what's too much.
00:09:46.836 --> 00:09:51.509
So the recommended amount in micrograms, not milligrams in micrograms.
00:09:52.196 --> 00:09:58.374
folate is 400 micrograms and that's an adults and those are non-pregnant adults.
00:09:58.423 --> 00:10:04.008
so if someone is pregnant, then it is 600 micrograms a day.
00:10:04.226 --> 00:10:05.562
So what I find really interesting.
00:10:06.357 --> 00:10:14.623
Folic acid as a supplement or in fortified foods is absorbed twice as much as the folate that's found in nature.
00:10:15.582 --> 00:10:23.393
And another little interesting tidbit is you'll only see folic acid on a nutrition label if it's been added.
00:10:23.679 --> 00:10:29.919
So if you're looking at whole wheat bread, that is not fortified, it's not going to have a folate level on there.
00:10:30.272 --> 00:10:32.534
But if it's a fortifying whole wheat bread, it will
00:10:32.585 --> 00:10:33.745
Oh, so interesting.
00:10:34.044 --> 00:10:34.585
Yeah.
00:10:34.792 --> 00:10:35.001
Yeah.
00:10:35.001 --> 00:10:44.241
That's an interesting thought because I just, I'm thinking about how many things have a label and then, you know, there's no, one's really telling us nutrient breakdown unless they know it because they put it back in there.
00:10:44.782 --> 00:10:45.052
Yeah.
00:10:45.052 --> 00:10:51.144
And I even looked at some things that I had in the house and, you know, you'll see like calcium level and, some other nutrients, but.
00:10:51.443 --> 00:10:55.159
If it's not fortified with folic acid, you're not going to see it on the label.
00:10:55.350 --> 00:11:01.533
You're not gonna know what's in a nice, you know, boule, a nice, a nice artisinal right.
00:11:01.683 --> 00:11:03.964
You're not gonna know what's in a nice artisinal loaf,
00:11:04.139 --> 00:11:04.470
right.
00:11:04.866 --> 00:11:05.917
That's something to think about.
00:11:06.067 --> 00:11:06.277
Yeah.
00:11:06.307 --> 00:11:07.027
Things that make you go.
00:11:07.057 --> 00:11:07.537
Hmm.
00:11:09.630 --> 00:11:10.711
Um, okay.
00:11:10.711 --> 00:11:10.980
So.
00:11:11.696 --> 00:11:21.126
folate itself has been shown to help with, you know, not only prevent well folate and folic acid are used to prevent anemia, right?
00:11:21.126 --> 00:11:29.346
So you're, you're taking the amount to reduce your risk of a certain disease So that's why pregnant women are recommended to supplement with.
00:11:30.246 --> 00:11:33.667
Folate or folic acid because it prevents neural tube defects.
00:11:34.116 --> 00:11:39.397
And so it's needed, like you're saying, like for DNA and for cellular development.
00:11:39.787 --> 00:11:44.886
And so that's really important when someone is pregnant because there's a lot of cell division going on.
00:11:45.130 --> 00:11:49.778
It's also has been shown to be helpful for cardiovascular support.
00:11:50.131 --> 00:11:51.211
Um, not only in.
00:11:51.846 --> 00:12:00.990
a developing fetus to prevent certain congenital heart defects, Foltate has been shown to reduce the risk of certain cancers.
00:12:01.183 --> 00:12:03.193
And that's sort of a double-edged sword, right?
00:12:03.193 --> 00:12:13.524
Because folate coming from food, fruits and vegetables has been shown to reduce the risk of certain cancers, but then taking too much folic acid.
00:12:14.019 --> 00:12:19.929
The synthetic version has been shown to possibly have adverse effects.
00:12:20.428 --> 00:12:32.460
There was a study many years ago that came out and when folic acid began to be fortified in bread, there was a study that showed there was an uptick of colorectal cancer.
00:12:33.215 --> 00:12:37.115
the question became, does folic acid promote colorectal cancer?
00:12:37.697 --> 00:12:39.855
Well, it turns out if you looked at the.
00:12:39.913 --> 00:12:44.623
Incidents of colorectal cancer over time, it bumped up and then it came back down.
00:12:44.812 --> 00:12:51.383
And now after many experiments with animals and further data, it's pretty clear what's happening.
00:12:51.732 --> 00:12:55.735
adequate folate helps normal division of cells.
00:12:55.753 --> 00:13:04.110
Once there's a polyp or add, Anoma When that is given folic acid, usually in a supplement or fortified food, it will grow.
00:13:04.139 --> 00:13:08.429
It will actually promote the growth of a precancerous adenomas into cancer.
00:13:08.832 --> 00:13:09.883
And once cancer is.
00:13:10.692 --> 00:13:22.222
It can promote the progression of colorectal cancer but cancer of the colon follows a very clear path from normal cells to polyp, to add Anoma to colorectal cancer.
00:13:22.913 --> 00:13:34.852
So if the folic acid is being given or eaten in any form, including folic acid, you know, in a supplement or fortified food, and there's no abnormal cells yet there's no precancerous lesions.
00:13:35.128 --> 00:13:36.597
That doesn't look like it's a risk factor.
00:13:36.597 --> 00:13:45.948
If anything, it's giving repletion of folate in the cells But what we don't know is, you know, who has precancerous, adenomas and who doesn't.
00:13:45.948 --> 00:13:55.259
And so when that was done in a large population and folic acid suddenly was in the bread supply, there was an uptake of colorectal cancer until that subpopulation didn't show up on any more in the data.
00:13:55.350 --> 00:14:07.570
So it's an, it's an interesting scenario of the same molecule folic acid, having a benefit for risk reduction of colorectal cancer and a detriment once there's precancer or cancer present.
00:14:07.659 --> 00:14:09.490
And it's pretty clear now that that's what's going on.
00:14:09.490 --> 00:14:11.830
So I do not recommend folic acid supplement.
00:14:12.700 --> 00:14:20.826
Especially in a higher dose, like over one milligram or, that's 1000 micrograms to anybody with a tendency towards a colorectal cancer
00:14:21.157 --> 00:14:22.807
or your history of,
00:14:22.956 --> 00:14:26.527
a history of colorectal cancer because we don't know if there's recurrence right.
00:14:26.527 --> 00:14:30.226
Ever, or anyone with actual known colorectal cancer.
00:14:30.356 --> 00:14:31.886
I prefer they get it all from food.
00:14:31.937 --> 00:14:44.198
and I think it's good to point out that like if somebody does, you know, is trying to reduce the risk or prevent cancer, taking higher doses of folic acid has not shown any benefit at all.
00:14:44.198 --> 00:14:46.905
So it's more the low folate status.
00:14:46.905 --> 00:14:47.105
That's.
00:14:47.650 --> 00:14:54.038
Associated with an increased cancer risk, but by supplementing with folic acid, it's not really going to be.
00:14:54.335 --> 00:14:55.024
Moving the bar.
00:14:55.325 --> 00:14:55.865
Right.
00:14:56.195 --> 00:14:59.254
And it may actually be detrimental if you have this history.
00:14:59.794 --> 00:15:00.784
Right, right.
00:15:00.784 --> 00:15:01.384
And yes,
00:15:01.684 --> 00:15:04.115
whether it's family history or personal history.
00:15:04.344 --> 00:15:04.614
Yeah.
00:15:04.644 --> 00:15:11.422
And you know, that, as a general rule, if something is known to reduce the risk of developing a cancer, you cannot extrapolate that.
00:15:11.422 --> 00:15:17.131
And say, once you have a known cancer, have history of a cancer that it's going to translate to that ever.
00:15:17.642 --> 00:15:17.822
Yeah.
00:15:17.822 --> 00:15:18.841
That's a perfect thing to point out.
00:15:19.636 --> 00:15:35.340
So one thing I do want to mention is, not only is folic acid found in foods like the fortified foods, like cereals and breads, but also it's in supplements and it's not necessarily just in B complex or multivitamins, because it can reduce the risk of.
00:15:35.885 --> 00:15:48.801
Things like Alzheimer's fully can, folic acid can be found in more of those kinds of cognitive supplements, the memory ones, the ones that are promoted as like this is going to make, uh, remember everything.
00:15:49.407 --> 00:15:51.807
the other place where I've seen it hidden.
00:15:51.807 --> 00:15:56.876
And I'm sure there are tons of places, but, um, I've also seen it hidden in energy drinks.
00:15:57.496 --> 00:15:57.736
Yeah.
00:15:57.767 --> 00:16:02.116
And so, and those doses can be the 400 microgram.
00:16:02.581 --> 00:16:08.520
So that's, that's another place to really be cautious because a lot of cancer survivors, a lot of cancer patients are really tired.
00:16:08.520 --> 00:16:19.099
And if they're pounding these, you know, energy drinks, maybe they're on a medication where, you know, you don't want them to take too much, or you don't want them to take it at all, or, you know, whatever.
00:16:19.099 --> 00:16:21.538
Like it's just, it's, it's looking at labels.
00:16:22.048 --> 00:16:22.519
Yeah.
00:16:22.678 --> 00:16:28.589
And it's easy to do because I think for the most part, people think B vitamins must only do.
00:16:29.489 --> 00:16:29.759
Right.
00:16:29.759 --> 00:16:30.688
You can compete them out.
00:16:30.688 --> 00:16:31.678
That's what everyone says.
00:16:31.708 --> 00:16:33.058
Oh, you can take as much as you want.
00:16:33.058 --> 00:16:34.589
You're just going to pee out what you don't need.
00:16:35.075 --> 00:16:35.434
Yeah.
00:16:35.434 --> 00:16:45.426
So another point that I think we had talked about the other day was that leucovorin, which is often part of the treatment for colorectal cancer.
00:16:45.426 --> 00:16:48.905
In addition to other cancers, it's, it's part of FOLFOX, right?
00:16:49.355 --> 00:16:52.775
It's the five Fu and leucovorin and then the oxaliplatin.
00:16:53.159 --> 00:16:55.868
That is a form of folic acid.
00:16:56.033 --> 00:16:56.722
Yeah.
