People eating potatoes – especially french fries – get diabetes type 2 more often, according to a new review of several big studies.

MedicalResearch.com: Potatoes, Especially French Fries, Raise Diabetes Risk

It should come as no surprise. Potatoes are full of carbs that instantly raise the blood sugar.

    Although the results might someday be shown to have merit, we should be mindful that this is just another Harvard/Willett epidemiology study review of the kind that's also used to show meat causes cancer and saturated fat causes heart attacks. Given Willett's track record, I wouldn't put too much stock in it either.

    "It should come as no surprise. Potatoes are full of carbs that instantly raise the blood sugar."
    And wholegrain doesn't?

    What do people who eat pommes frites fill the rest og their plate with, not to mention what do they drink to their meal? Fried potatoes are usually just a side dish to processed food like hamburgers or fried food.

    This is just as stupid as claiming that coffee reduces risk og diabetes. What do people who don't drink coffee drink? Juice, lemonade or soda?
    If they stick to just water, would coffee still be shown to reduce risk?

  2. Yes of course, and I'm careful *not* to say that it proves any causation, because it doesn't.

    What about the sugar laden ketchup most French Fry eaters are slathering on? Also, most "french fries" aren't just potato, but coated with divinity knows what. Potatoes, maybe a problem. The way they are processed and eaten? Definitely.

    Potatoes do not belong to a LCHF diet.

    For 100 gr of boiled potatoes you have 20 gr of carbohydrates.

    For 100 gr of spinach, cooked, boiled, drained you have 3.75 gr of carbohydrates.

    My choice is obvious.

    I've been on a very strict LCHF diet for almost two years now, with only a handful of times when I've gone off the diet (such as on vacation). I, however, am beginning to eat potatoes and other starches, primarily to get my resistant starch up. I was having irritable bowel type of symptoms, where I'd eat then almost immediately have to go to the bathroom or get a sudden urge to go to the bathroom. The other problem I was having was feeling as if I had to go to the bathroom even though I didn't. These occurred while on low carb, although they may have been occurring beforehand too. That is, I don't think low carb caused the IBS, but I don't think low carb necessarily helped either. Intermittent fasting and LCHF in combination, which I started to do this year, seemed to help a bit, but these did not cure it. So, I've been adding raw potatoes, cooked then cooled then reheated potatoes, plantains, potato starch, etc., to my diet and eating a lot of fermented foods. This has seemed to help, although I'm only about a month into this regimen. I plan on trying this for a few months.

    Am I concerned that I'm taking in too many carbs? Yes. However, I'm trying to eat small amounts of these and trying to eat foods that are the highest in resistant starch with the fewest carbs. There is also some evidence that foods with high amounts of resistant starch do not cause blood sugar spikes to the extent we think they do and may actually cause blood sugar to go down over time. I'm not sure how much I believe these, but I'm willing to try eating higher carb if it actually reduces or cures my IBS-like symptoms.

    re: What about the sugar laden ketchup most French Fry eaters are slathering on?

    It's a problem (and no-sugar-added ketchup is available, but not sugar-free, as tomatoes naturally contain sugar). But generic ketchup is probably less of one than the total risk represented by fries. Fast food fries are complete disasters. It's easy to find cautionary pages like this one:
    http://www.care2.com/greenliving/shocking-ingredients-in-mcdonalds-fr...
    and they usually overlook several additional problems, like whether some of those chemicals are microbiome antagonists, AGEs and cross-contamination from breaded items cooked in the same awful oils. The salt might be the safest ingredient present.

    Minimize cooked potato of any kind. Raw potato, and its starch, from organic potatoes, on the other hand, is a fine adjunct to a sane diet. Whether to go non-GMO depends on the specific GMO, and the field practices it enables.

    I'm having a hard time understanding why someone on an LCHF diet would deliberately introduce starches or other carbs (for so-called health reasons). I find that carbs sneak their way into my diet (the occasional piece of potato, grains of quinoa, oats ....whatever I tried to avoid ingesting while eating at a restaurant, work, or friends house...). Even the occasional fruit (strawberry, blueberry, etc) I eat has some sugar. I find it hard enough to nibble around carbaceous food, eating only the meats and natural fats, discarding the rest, as a grand feat itself. Even though I am on a strict LCHF diet myself, I am surrounded by people who eat in a completely different manner (mostly carbs). And, most all of them are on some sort of medication (diabetes, blood pressure, arthritis, sleep disorders...etc...). While I am on zero medications! They continue to eat garbage, and I pick out the good parts and discard the rest of the food I find dangerous for human consumption (like French fries, potatoes, grains, vegetable oil, sugary foods, etc).

    Why on earth would anyone who says that they are on an LCHF diet deliberately eat potatoes, or whole grains, or whatever....resistant starch? Carb re feeding? ....give me a break!!!! Sorry...I'm not buying it. Eat some full fat yogurt. Or, Eat high fibre veg, like avocados. Eat naturally fermented pickles. Eat grass fed meats and fats. Stop eating the BS pumpkin-spice-latte-imitation-Atkins-style-granola-bars.

    Eat clean. Stop it with the bizarro food schemes. Stop convincing yourself that you are a butterfly with very unique eating needs. Enough.

    and do some fasting too. Give your body some "no food" time, so that it can spend some time cleaning out (consuming old body tissue), renovating itself. Try it...go for one day, two days, or a whole week....nothing but water or tea. If you get stomach pains or diarrhea after restarting eating after a fast...it means your body could have gone longer on the fast.

    If you are feeling like crap on an LCHF diet, it doesn't mean you need to re introduce starch or carbs....do fasting instead. Your body is telling you it has way too much nutrients...and way too much junk to clean out...you can stop and give it some time to clean itself out.

    I have tried the starch diet potatoes with no butter with good results weight loss and feeling great unfortunately very difficult to stick to for me. Low carb works great but I always get a nagging feeling all this meat may cause some problems in the future time will tell
  12. Tor H
    Who are you eating more meat?
    You're supposed to replace carbs with natural fats like butter, full fat cream, olive oil etc.

    All potato foods, especially French fries.

    "In this analysis, we focused on diabetes and found that a higher consumption of total potato foods and individual potato foods, especially french fries, was associated with an increased risk of developing type 2 diabetes in three large cohort studies of ~200 thousand U.S. men and women. In addition, we found that increased potato food consumption over time was associated with a subsequent increased risk of developing diabetes."

    Potatoes are nightshades but cooking , especially pressure cooking, detoxifies them to a large extent. It may cause problems for people sensitive to nightshades to eat raw potatoes, especially if there is any green in the skin.

    I think this tirade is directed at me. I fast all the time. I've done many 3 day fasts and one 5 day fast (blood pressure went too low), and I no longer eat breakfast and eat (when I do eat) during a window, usually noon-2pm to about 9pm (I get home at 7:30pm).

    LCHF allowed me to lose about 20-25 pounds in about 15 months. Adding intermittent fasting has allowed me to lose another 25 pounds in about 9 months.

    However, I still had IBS-like symptoms. That is, I would eat and immediately have to go to the bathroom or immediately have to go to the bathroom while driving home from a restaurant. Try finding a bathroom in the middle of BFE New England. Also, when I fast for 3 days or more, I do not have a bile movement at all until I eat, and then I'll have 7-10 (all water) over the next day or so. These things aren't fun.

    In an effort to attempt to fix this, I've been eating resistant starch, including potato starch and raw potatoes and plantains. I have not seen any rise in blood sugar, but then again I also don't test my blood sugar and have to go by feel instead (believe me, I can still feel high carb like bread and ice cream). This has seemed to help my IBS-like symptoms, and if there are ill effects, I've not found them. I've not gained weight for instance (in fact lost a few more pounds), and I've noticed much better sleep. I've also become more regular. I've noticed a lessening in the duration of the number of times I have to go to the bathroom after fasting (from more than one day to basically the rest of the first day).

    For me, I'm going to continue to do this, and we'll see what happens. My ultimate goal is not to have to eat resistant starch, but the possibility exists that my system is out of whack and needs to get whacked back into place. Once it's whacked back into place, then I'll go back to eating little or no resistant starch to see what happens.

    I've eaten raw potatoes many times in my life (used to eat them as a kid all the time). Have never developed anything. There may be people who have problems with raw potatoes, but I'm not one of them.

    I certainly did not target my comment only to you. There are many on this site who tell others to introduce potatoes or potato starch into an LCHF diet, which then leads these people astray. It confused the heck out of me too when I just started out with LCHF. I believe the answer is in eating real foods your ancestors would recognize. Not powders, concoctions, pills, etc. and not potatoes or other foods that cause blood sugar to spike.
    I feel sorry for your condition, and I know how you feel. I too had similar problems.
    Have you tried increasing the amount of olives in your diet? I'm of European origin, so I eat what my ancestors would recognize. Olives was a huge component of their diet. They are fermented food that are full of fibre - perfect for gut health. Eating real foods that my ancestors would recognize in combination with fasting has cured me of my IBS.
    I hope you find what works for you.

    Bob, numerous IBS health sites on the web list nightshades as problematic for IBS, especially raw. I don't know what research that advice is based on, but you might want to check it out.
  20. Tor H
    Those IBS-sites I've seen tries to find some other cause of IBS than carbohydrates.
    It's like they need to continue to consume sugars and starches for some reason.
    Addictive behavior??

    BobM did you try coconut flour in your diet?

    "High in Fiber
    Coconut meat itself supplies an impressive 61% dietary fiber! And because fiber essentially cannot be absorbed by the body, some of the calories and carbohydrates found in coconut flour aren’t even absorbed and used, but rather they move right through the digestive tract helping to take toxins and waste along with them."

    I often buy 5kg bags (11lb) and eat them all myself - not fat at all.
    Though not 'thin' - more like lean and muscular :)

    I dont drink coffee at all. And I only drink tea in social situations. I drink water, sparkling mineral water and coke zero. Just coz you dont drink coffee doesnt mean u are drinking juice.

    People usually have more than one source of carbs in their diet. Soft drinks, starchy and/or sugary foods etc.
    Even foods that only increase insulin levels increase risk of diabetes 2 if eaten too often. Like foods high in protein.
  25. Samantha
    I have. I am a thin (well... slim) person who has bought big bags of potatoes. Lack of evidence isn't evidence for the opposite.

    Also in the conclusion: "Replacement of potatoes with whole grains was associated with a lower T2D risk."

    So what are we supposed to make of this exactly?

    If we replace starchy potatoes with naturally contaminated (by gluten etc.) starchy wholegrain it's supposed to make us healthier?
    That doesn't sound right to me.
    My money is on the industrial/crappy/cheap vegetable oils.

    Your wrong about whole grains. Two slices of whole wheat bread is the same as 6 teaspoons of sugar. In fact, Wheat causes diabetes by destroying beta cells.

    According to Jason Fung, beta cells are not destroyed but become embedded in fat.
    Verified by Taylor, Newcastle University with sophisticated MRI scans of liver and pancreas.
    Intermittent fasting (reasonable) or extreme low calorie diet or GBP removes the fat and restores the function = cures diabetes and metabolic syndrome, hence heart disease as I understand.
    Too much tasty wheat bread may be the simple reason. https://intensivedietarymanagement.com/fatty-pancreas-t2d-9/

    If you boil the potatoes and keep them in the fridge over night and than cook them again, they drop from 20 to 10 carbs. And they do not show up on my blood sugar test 1h after meal.
