The Basics

Dr Fuhrman Diet Can You Eat Potatoes Dr McDougall versus Dr Fuhrman on potatoes The Starch Solution 6 week eat to live plan potatoesLet’s get on the same page about where potatoes fit into your whole-food, plant-based, nutritarian lifestyle.

We’re talking about ALL. THE. POTATOES.

White, yellow, red, sweet, purple-sweet, purple-fingerlings–seriously, who knew there were so many kinds of potatoes to know about?

We’re covering it all because, I don’t know about you, but I think potatoes are glorious and want to enjoy them in my nutritarian lifestyle.  But I also understand that the goal of eating nutritarian is to maximize the amount of nutrients you consume, and potatoes don’t fare so well in that area compared to other whole plant foods.

So, where is that fine middle ground between I-want-a-potato-at-every-meal and this is the amount of potato you can eat and still be loosing weight and/or achieving health excellence?

Let’s figure out what the science says so we can eat potatoes in the most favorable, health-promoting way possible!

We’re going to answer these questions:

  1. Can you eat potatoes on the nutritarian diet?
  2. How much potato should you be eating?
  3. What are the best types of potatoes to eat?
  4. How should you eat potatoes?

And we’re compiling all of Dr. Fuhrman’s potato-eating advice from his books: Eat to Live (2003), Super Immunity (2011), The End of Diabetes (2013), The End of Dieting (2014), and The End of Heart Disease (2016)–with a bit of extra guidance from Dr. Greger’s opus How Not to Die (2015).

All of this information is laid out for you here to truly understand where potatoes fall in the eating-for-health continuum.

So, are you ready to dig in?

Let’s get to it…

What are the best potatoes to eat on Dr Fuhrmans nutritarian 6 week eat to live aggressive weight loss plan Dr Greger daily dozen Dr McDougall Dr GoldhamerYou Can Eat Potatoes on the Nutritarian Plan (But There’s a Pretty Big “If”)

In Eat to Live (p. 216), Dr. Fuhrman lists both sweet and white potatoes under the “limited” category of his Six-Week Plan as follows:

“Cooked starchy vegetables or whole grains: butternut and acorn squashes, corn, white potatoes, rice, sweet potatoes, bread, cereal (not more than one serving, or 1 cup per day)”

This is the advice that I’ve always followed that conforms to Dr. Fuhrman’s aggressive weight loss plan.  And I’ll be the first to admit that there are weeks where I choose to exclusively eat potatoes as my 1 cup “cooked starchy vegetable/whole grain” allotment for the day, #sorrynotsorry.

Dr. Fuhrman definitely restricts this food category more than most other plant-based doctors, most famously Dr. Esselstyn and Dr. McDougall, because he considers starchy vegetables and whole grains to be “the culprit for those who have difficulty losing weight” (Eat to Live, p. 216).

Dr. Fuhrman also considers starchy vegetables like potatoes and whole grains to be less-than-ideal high-carbohydrate choices and considers beans, corn, wild rice, barley, steel-cut oats, oatmeal, squashes, berries, and fresh fruits to be the more favorable selections (Super Immunity, p. 113).

Are You a Candidate for Frequent Potato Consumption?

So, there’s a pretty big caveat to eating potatoes as part of your “cooked starchy vegetable/whole grain” allotment on a regular basis.

Potatoes (both white and sweet) effect people differently.  That’s to say that eating potatoes can be benign for one person’s health while being harmful or counter-productive to another person’s health.

In his more recent works, The End of Heart Disease (p.34-5), The End of Diabetes (p. 102-4), and The End of Dieting (p.133) Dr. Fuhrman advises you avoid white or sweet potatoes if:

  1. you’re overweight, specifically with a hindrance for weight loss
  2. you have diabetes

If you fall into either of these groups, potatoes are likely not the ideal high-carbohydrate choice for you while following a nutritarian diet.

Unfortunately, “because of the fat-promoting effects of insulin, high-gycemic foods can make it more difficult for an overweight person to lose weight” (The End of Heart Disease, p.35).

This all makes complete sense when you take a look at potatoes’ high glycemic load:

  • sweet potatoes: 19
  • white potatoes: 29

“[I]f you’re significantly overweight or diabetic [Dr. Fuhrman] recommend[s] limiting brown rice, millet and even sweet potatoes, as high glycemic load foods are generally considered 20 and above” (The End of Dieting, p.133).

And you need to tighten the bolts even more if you’re diabetic by “avoid[ing] regular and liberal consumption of foods with a GL above 15, at least until [your] diabetes is in better control and [your] weight as dropped significantly” (The End of Diabetes, p.104).

But, even if you fall into one of these categories, that doesn’t mean you can never eat potatoes again!

It just means that you should “limit” these higher-glycemic-load foods to an occasional option and choose more beneficial high-carbohydrate choices (like beans and whole, unprocessed grains) more frequently.  Remember that’s only going to be until you resolve your weight and diabetes with a period of prolonged nutritarian living.

And this leads us beautifully into our next topic…

3 Can you eat white potatoes on Dr Fuhrman 6 week eat to live plan high starch potato types The Starch Solution Dr McDougall DrHow Much Potato Should You Be Eating on the Nutritarian Plan (and Still Lose Weight)?

As we’ve discussed before, there are a spectrum of different plans under the nutritarian umbrella.

Let’s assume that if you’re reading this article right now, you’re more than a nutritarian novice (who would likely be following the more liberal Basic Guidelines approach).

So, let’s focus on the Aggressive Weight-Loss Plan where the goal is losing weight.  This plan allows you to eat up to 1 cup of “cooked starchy vegetable/whole grains” daily.

We learned earlier that white and sweet potatoes are considered part of that limited food group, so you could technically have a max of 1 cup of potatoes daily (with no other options from that food group or the day).

Yes, you can eat potatoes daily and still lose weight!

Go ahead and do it: happy dance, cabbage-patch, get to dabbing–cause that’s certainly cause for celebration in my book!

The reason you can make it happen is because the amount of potato your eating is restricted to only one cup.  And (hello!) you’re going to be positively stuffing yourself with 1 pound raw and 1 pound cooked veggies daily.  So it shouldn’t come as a surprise that you will continue to lose weight!

But remember those two big caveats from earlier?  If you’re considerably overweight or diabetic, you don’t want to be eating potatoes daily.  You want to “limit” them.

Now, Dr. Fuhrman doesn’t come right out with a number as to what “limiting” means in any of his books, but I would take it to mean no more than once or twice weekly.

Can You Eat More Than 1 Cup of Cooked Starchy Vegetable / Whole Grains?

This is kinda critical to explore, don’t you think?  I don’t know about you, but the opportunity to eat more potatoes and still reach my health goals is an opportunity I’m not willing to pass up!

When I went to Dr. Fuhrman’s Culinary Getaway last May, the topic of eating more than the recommended 1 cup of “cooked starchy vegetables/whole grains” definitely came up at our Q&A sessions.

Dr. Fuhrman conceded that you technically can eat more high-carbohydrates from the “cooked starchy vegetable or whole grain” category if you’re physically active and you continue to lose weight following the nutritarian plan.

Each person has to find the level that works for them (we aren’t just carbon copies of one another).  And, again, this is for people who don’t fall into either of those two problematic groups.

The only way you can gauge how much you can eat in this category, taking into account your specific activity levels and body type, is to test it out and see what happens.  If you have 2 to 3 weeks of consistently not losing weight (when you have weight to lose) then you need to adjust your portions in the limited foods category (which includes: starchy veggies / whole grains, avocado and nuts & seeds).

This is where things get interesting…

Cause if you know anything about me, you know that I’m seriously turned-on by brightly-colored produce, and my eyes have been opened my friends to the wonderful world of pigmented potatoes!

There’s a whole amazing world out there of heirloom potato varieties in jaw-dropping shapes and colors (just take a look at what you can find in a farmer’s market in New York)!

I started paying attention to potatoes when I discovered tiny purple fingerling potatoes at my local Sprouts and Whole Foods supermarkets.  Then I did some research and discovered just how amazingly nutrient-packed these mega-hued tubers can be (and we’re going to learn all about that very soon)!

So, what gives with all these fancy-colored potatoes?

The bottom line is pigments = more antioxidants and phytochemicals.  And we want as many of those in our bodies as possible because they protect us from disease, fight cancer, ward of dementia and slow the aging process!

But I promise you, you don’t need to scour the farmer’s market or the fancier grocery stores to track down blue and purple potatoes!

You’ve got a serious nutrient-rich-winner that’s easy to find anywhere, super-cheap and ready to serve your healthy lifestyle…

The best potatoes to eat on Dr Joel Fuhrman nutritarian eat to live 6 week plan Why are sweet potatoes healthiestSweet Potatoes Are Preferred

Dr. Fuhrman only deals with two kinds of potatoes in his materials: white and sweet.  And by “sweet potatoes” he is referring to garnet yams (the terms are interchangeable here in the US).

He doesn’t make the extra distinctions between different colored sweet potatoes and he doesn’t talk about higher-nutrient non-sweet potato varieties.

We’re left with his positions on white and sweet, and he favors sweet by a landslide.

And he’s in good company too, Dr. Greger has nothing but rave reviews, hailing them as superfoods, and ranking them as one of the healthiest foods on the plant:  “[Sweet potatoes] are among the healthiest and cheapest [foods], with one of the highest nutrient-rich food scores per dollar” (How Not to Die, p.327).

Dr. Fuhrman gives higher marks to sweet potatoes on his ANDI scoring scale (a way to compare the nutrient-density of different foods based on different health-promoting factors) and ranks white potatoes (with the same score as avocado) just a smidgen higher than cashews, oatmeal and chicken (The End of Dieting, p. 126-7).

  • White Potatoes ANDI score: 28
  • Sweet Potatoes ANDI score: 181

It seems that Dr. Fuhrman has warmed up a bit to white potatoes in the past few years, even releasing a position paper on white potatoes where he concedes that when they’re cooked and topped “in appropriate manner” they are far superior to processed foods and can be a helpful tool to transitioning into a healthy lifestyle.

Dr. Greger can provide us with a bit more guidance on potatoes and broadens the white/sweet argument to include a relatively new player to the potato-game here in the US…

Insert record-scratching-to-a-halt sound here.

I get it!  Very few people have heard about, let alone seen, a purple potato while on their weekly grocery shopping trip.

They are a decidedly recent trend here in the US and a very welcome and happy development when you’re a bonafide-potato-lover like me!

While Dr. Greger agrees with Dr. Fuhrman that “sweet potatoes are healthier than plain potatoes” he points out that “if you’re going to choose the latter, seek out those with blue or purple flesh” (How Not to Die, p. 328).

Honestly, it’s music to my savory-flavor-loving ears because after spending the first 4 years of my nutritarian journey exclusively eating sweet potatoes I was in desperate need of a change!

Dr. Greger reviews and analyzes a study where people ate one boiled purple potato a day for six weeks and they “significantly decrease[d] [their] inflammation, something neither white nor yellow potatoes were able to accomplish” (How Not to Die, p. 328 & this video).

Here are more amazing benefits of blue/purple potatoes that Dr. Greger discusses in How Not to Die (p.328):

  • purple potatoes increased the antioxidant capacity of study subjects’ bloodstream (white potatoes actually had pro-oxidant effects)
  • blue potatoes may have ten times more antioxidant power than regular white potatoes
  • eating 6 to 8 small microwaved purple potatoes daily was able to lower study participants’ blood pressure levels within a month

Dr. Greger goes on to say that “purple sweet potatoes may offer the best of both worlds” (How Not to Die, p.328).  It makes sense that they essentially marry the increased antioxidant power and lower glycemic load of sweet potatoes with the special benefits of purple-fleshed potatoes we outlined above!

Purple Sweet Potato recipes Hello Nutritarian Dr Fuhrman 6 week eat to live diet Dr Greger How Not to DieThe Best Way to Eat Potatoes

Potatoes have a higher glycemic index and glycemic load than other vegetables, that fact is undeniable.

But that’s not the end of the story.

Dr. Fuhrman makes an important distinction: “Instead of focusing narrowly on the concept of glycemic index, we have to consider the other values of the food as well as the the healthful qualities and the glycemic load of the entire meal when put together.  By the way, weight loss and micronutrient adequacy are more important than minor and temporary fluctuations in blood sugar” (The End of Diabetes, p. 50).

In other words, “[i]t is not the inclusion or exclusion of a whole plant food like a potato that will make a diet good or bad” (The End of Heart Disease, p. 35).

So, what’s the best way to enjoy your potatoes?

The absolute best way to eat any potato is with beans in the same meal since beans “reduce the glycemic effect of other foods, even those eaten at separate meals.” (The End of Heart Disease, p.37).

Luckily for us nutritarians, we eat at least 1 cup of beans daily.  That means that potatoes (of any variety) will never unleash their full glycemic potential in our systems because we have built-in, bean-eating protection!

How to Eat Purple Sweet Potatoes

As you can see from the two salads above, my favorite way to eat purple sweet potatoes is as part of my two giant salads for the day.

I find that they go particularly well with this No-Oil Beet Hummus Recipe and a drizzle of good-quality balsamic vinegar!

Let’s break down some more meal ideas and cooking methods for the rest of the potato varieties we’ve discussed…

white potato nutritarian vegan oil free no oil recipes What is the best way to eat potatoes Dr. Fuhrman Eat to Live Dr McDougall potatoes recipesHow to Eat White Potatoes

Dr. Fuhrman recommends eating your white potatoes with greens, beans, nuts and seeds (The End of Heart Disease, p.35). 

You also want to be mindful and purchase organic white, yellow or red potatoes as they are one of the top 12 foods with the most pesticides in the US. 

If you want to be a white-potato-eating rock star then boiling or microwaving a small yellow potato and using it to top a kale salad (as you can see above, right) and adding beans, sprouts and a healthful no-oil dressing is going to give you an A++ in nutritarian compliance.

But we all know that there are times where you just want a nutrify-ed taste of comfort or a more share-able recipe when the holidays strike.  For such occasions, you’ll be glad you have this Nutritarian Mashed Potato Recipe on deck (it’s one of the most highly -reviewed recipes on the site)!

Nutritarian Sweet Potato Recipes whats the best way to eat potatoes Dr Fuhrman Dr Greger How not to die Dr McDougallHow to Eat Sweet Potatoes / Yams

The best way to cook a sweet potato, to retain and preserve their nutritional content, is to boil them (How Not to Die, p.327).  

But regardless if you decide to microwave, bake or broil them, it’s best to keep the skin on since “[t]he peel of the sweet potato has nearly ten times the antioxidant power as the inner flesh, giving them an antioxidant capacity approaching that of blueberries” (How Not to Die, p.327).

Sweet potatoes are one of the foods with the least pesticides, so you can purchase these conventionally grown rather than organic. 

As you can see above, my favorite way to eat sweet potatoes is baked or microwaved, on top of my salads (often with avocado), with a generous serving of this Extra-Creamy No-Oil Humus Recipe or a hummus-based dressing.

As I mentioned before, these little blue-beauties have been my recent potato of choice!

My favorite way to enjoy them is boiled–they keep fabulously in a glass container for up to 12 days after boiling.

I add them to my salads cold or warm them up and eat them with cooked spinach or kale and my favorite Nutritarian Cashew Cheese Sauce Recipe!

    Honestly, after just finishing my dinner of two small white potatoes, reading this was just what I needed. Thank you so much for all the work that went into compiling all this info! Sometimes it’s easy to get bogged down by all the seemingly contradictory advice by these great doctors, so it’s nice to realign myself with what I need to be at my best health level. I’ll be saving this article to read and reread. Thank you!!!

    • Kristen | Hello Nutritarian says:

  • Michelle says:

    This is great! Now I have some serious sources to back up my discussions with my husband about why potatoes aren’t the villains that they’ve been made out to be. I don’t eat them often, but sometimes they just really hit the spot.

    I’d like to recommend one of my favorite ways to eat them (always with the salad first, of course). Slice any potato into wedges and roast completely unadorned on a baking sheet lined with parchment (parchment seems to work better than a silicon mat in this recipe). When they’re done, top with your favorite chili recipe and the cashew cheese sauce from this site (or your fav). Adding extra veggies on top is good too, like steamed broccoli and/or cauliflower. So yes, you can literally have nutritarian chili cheese fries! 😉

    • Kristen | Hello Nutritarian says:

      Hi Michelle,

      WOW!! Those nutritarian chili cheese fries sound simply amazing!

    I discovered this UK research and think it’s worth a look.

    Cooking, cooling, and reheating potatoes ( and rice and pasta) lowers the GI fairly significantly. Although it’s not a license to overeat these foods, it adds some flexibility for those of us who love potatoes, especially.

    I just found your blog and appreciate it – have most of Fuhrman’s books and (mostly) following a nutritarian diet for 6+ years.

    I really enjoyed learning about the different types of potatoes. I searched on line and found I could buy a red and a purple potato here in Australia. I have sent away for one of each, a bit pricey at $10 each plus postage, so hopefully I may be able to grow some. I have never seen them for sale in the shops.

    hi, Kristen What’s wrong with power blending a whole big salad?

    • Kristen Hong says:

      Hi John,

      Noting wrong with blending it all up if that’s something you want to do.

      I will say the Dr. Fuhrman does say that it’s good for our jawline to chew on crunchy veggies and the saliva that’s excreted during chewing can maximize certain phytochemicals.

      But I’m all about doing it in a way that’s sustainable for you!
