White Potatos

I'm on day 6 of my first Whole 30.  I'm actually enjoyed sweet potatoes more than I ever thought I would, but my husband is missing white for sure.  I didn't realize they are allowed now.  When did that change??

You can eat a whole sack of white potatoes per day and be compliant with the Whole30. However, you almost certainly should NOT eat white potatoes more often than you eat spinach or kale or broccoli, etc. 

This made me laugh so hard I was worried I'd wake up my sleeping children. (Then it made me think about how much greens I ate yesterday...)

Other than fruits permitted in cooking, white potatoes are the highest glycemic load of any permitted food.  They cause insulin response, keep you on the two hour hunger cycle, and potentially perpetuate insulin resistance.  In large portions, they interfere with achieving glycogenic/ketogenic balance.  With the skin on, the phytates in the skin make them nutritionally void.

 

But the bosses say eat 'em up, so I'll be making Coquille Saint Jacques as always this holiday season.  Now I just need a compliant tiramisu recipe...  Right.

wait the skin makes them nutritionally void?  While I've read about some negative issues with the skin the amounts needed to cause toxicity are if your eating a lot of potatoes.   I keep seeing your supposed to eat with the skin on to gain the most nutrition from them.  Now I'm confused.  I was adding them back into my soups and breakfast but this is a mistake?

This article is a good summary:  http://www.livestrong.com/article/486810-potato-vs-grains-and-phytic-acid/

 

Main take-away:  phytic acid not only bonds (chelates) with nutrients in the potato rendering them indigestible, it also bonds to what you're eating with the potato.  It's like all the shiny happy vitamins and minerals get on the bus and fly down the carpool lane.

 

Links at the end of that article if you want to ubergeek it.

I would like to hear Melissa and Dallas's take on this.  

 

You have 2 different authors on that site both talking about Phytic acid.. one makes you think it is the most evil thing in the world the other states that you actually need to have it.  

 

http://www.livestrong.com/article/519063-phytic-acid-in-bananas/

 

"Phytic acid has both nutritional benefits and adverse effects, making it especially important to balance your intake levels. If you suffer from mineral deficiencies, you may need to reduce your intake of phytic acid to increase your body's ability to absorb the minerals properly. However, if you are at high risk for developing colon cancer, phytic acid may help protect your body from developing it. The book "Nutrition for Health, Fitness, and Sport" recommends about 100 mg of phytic acid each day; however, your doctor should be able to determine exactly how much phytic acid is right for you."

Pages 110-112 in the Kindle edition of ISWF talks about phytic acid.  Paraphrasing, they lament that you can't peel grains like you can peel starchy root vegetables to get rid of the phytates, but they also say that most vegetables have enough nutrients that they outweigh the phytic acid.

 

A white potato has potassium, magnesium, Vitamin C and Vitamin B-6.  Of those, the phytic acid will go after the magnesium and the protein.

I'm wondering if potatoes are going to be on everyone's Thanksgiving menu now.

 

As for me, I can't really eat them because 1) the glycemic load gives me an immediate slump and I start yawning like crazy, and 2) mashed they are food without breaks for me.

LOL....I haven't  started this diet yet...mainly due to the holidays. Really bad time to start it. I am going for Jan 1st. So yes, I will be having mash potatoes, and real bread stuffing along with all the desserts. After the 1st...I will get serious, but it looks like  I can still have potatoes. Yay!  :)

I am really glad that white potatoes were not allowed when I did my first two Whole30s.

 

Yes, it would have made the times I had to eat out easier, but I would never have discovered one of my new favorites - the rutabaga!

 

I use rutabagas instead of potatoes for shredded hash and cubed in stews, and prefer Nom Nom Paleo's Autumn Root Vegetable Mash to mashed potatoes. Once you try this blend of cauliflower, carrots, and parsnips (I sometimes sub rutabaga) you will be sold! Maybe the best part is you can use the food processor to whip it up without worry - unlike potatoes, they won't get weirdly gummy.

That site is often about as useful as buzzfeed --- there doesn't seem to be any sort of criteria for what gets posted, and it all seems to be about SEO.

I completely eliminated potatoes and bananas at one point to work on my elevated blood sugar levels.  Earlier this year I stared eating potatoes and bananas again for a couple of reasons.  When I do not eat these 2 foods, I get cramps in my legs at night.  I can easily buy organic bananas and local/organic potatoes (I do live in Idaho!) that are not too expensive.  I now only buy small colored potatoes (blue, red and yellow) instead of "white".  With this buying strategy, I get more skin per serving and therefore increase the nutrients available from the potatoes.  Also, the color of veggies and fruits is an indication of nutritional value.  I believe in eating local, in season produce as much as possible...so potatoes are a go to food for me in winter.

The last time i looked into potatos, everything i read was saying not to eat the skin because that's where the majority or antinutrients are and also because of the phytic acid.  That being said, i think i was reading mostly in regards to white potatos.  I wonder if Whole30 has a stance on the skin?  Good or bad?

I know I have read the Hartwigs recommending people avoid the peels, but I can't find the source at the moment. I'll post a quote if I find it.

It's not that nightshades are explicitly wonderful or terrible; context matters. For some people (maybe 1 in 10), nightshades are generally poorly tolerated and can exacerbate inflammatory (especially joint-related) conditions. So from that perspective, potatoes, tomatoes, peppers and eggplant (etc.) are all in the same "category" of poorly-tolerated foods. (Shameless plug: our upcoming book, It Starts With Food [http://bit.ly/iswfamazon], details an autoimmune-specific protocol if that is an additional factor for some folks.) So potatoes *may* be problematic from a inflammatory perspective. But the arbitrary exclusion of them has more to do with changing habits and patterns on your Whole30, and choosing very nutrient-dense foods the most often. Since most Western eaters consume potatoes as fries, chips, or mashed/baked potatoes (all of which are notoriously easy to overconsume), we encourage folks to find and eat more nutrient-dense veggies on their Whole30 (and beyond!). Emily's comment here already demonstrated our point with potatoes pushing other veggies off the plate, which we think is generally a suboptimal choice. Best of luck!

Depends on your context, Jodi. Assuming you're healthy with no autoimmune condition or gut permeability issues, white potatoes are probably fine to add in occasionally. Because the most problematic part of the potato is the skin, even though I DON'T have any of those issues, I still make sure to peel them.

Recommended consumption depends entirely on your individual psychological and physical context. If you are active, healthy, and lean, you may include potatoes every day in some form or another, to ensure you are getting adequate carbohydrates to support your activity level. If you’re sedentary, overweight, and otherwise metabolically challenge, you’ll probably eat none during your program (or very few, in very limited amounts).

It shows that most of the glycoalkaloids in potatoes are in the skin, so they should be peeled, organic or not, especially red (new) potatoes. 

Sweet potato peels, but I usually avoid them too just to be safe.
 
If the potatoes are organic I scrub them well and eat the peel. If they are new potatoes and organic I eat the peel. If they aren't - I peel them.
 
Sweet potatoes are not nightshades. We call them potatoes, but they're from a different family, and the peels are fine to eat.

Even with regular potatoes, the glycoalkaloid levels are fairly low in many varieties unless the potatoes have started to green. I don't think it's harmful to eat the skins now and then as long as you've checked the potatoes for greening first and they aren't one of the higher glycoalkaloid types.

On the other hand, many do not eat the peelings of white potatoes.

 

Saponins derive their name from their ability to form “soap” like foams when mixed with water. Chemically, certain potato saponins are commonly referred to as glycoalkaloids. Their function is to protect the potato plant’s root (tuber) from microbial and insect attack. When consumed by potential predators, glycoalkaloids protect the potato because they act as a toxin. These compounds exert their toxic effects by dissolving cell membranes. When rodents and larger animals, including humans, eat glycoalkaloid containing tubers such as potatoes, these substances frequently create holes in the gut lining, thereby increasing intestinal permeability. If glycoalkaloids enter our bloodstream in sufficient concentrations, they cause hemolysis (destruction of the cell membrane) of our red blood cells.

The figure below shows how glycoalkaloids and saponins in general disrupt cell membranes leading to a leaky gut or red blood cell rupturing. These compounds first bind cholesterol molecules in cell membranes, and in the series of steps that follows, you can see how saponins cause portions of the cell membrane to buckle and eventually break free, forming a pore or a hole in the membrane.
