Does the link between white potatoes and diabetes extend to fried potatoes without butter or sour cream?
The problem for white potatoes began in 2006, when the Harvard Nurses’ Health Study studied the diets and illnesses of thousands of women for 20 years. found Higher potato consumption was associated with a greater likelihood of developing type 2 diabetes. However, Americans’ hundred or more pounds of potatoes eat Every year, the majority of potatoes are in deep-fried forms of chips, French fries or other processed products. what happened when they saw Especially on mashed or baked potatoes? They found the same association with diabetes. OK, but what can potato eaters eat more of? Maybe I should say it again: What more meat and potatoes can people eat? In fact, people who ate more potatoes also ate more meat, and we know that animal protein can Connected With increased risk of diabetes. But researchers tried to statistically adjust For that and still the risk was found to be increased with potatoes.
Well, what do people do Keep On baked and mashed potatoes? Butter and sour cream. Again, researchers tried adjust Effectively looking at the ratio between plant and animal fats along with other dietary factors such as this and whether potato eaters drank more soda or perhaps skimped on other vegetables. Nevertheless, there appears to be a link between potatoes and diabetes.
Okay, but that was just a study. By 2015, Harvard researchers also saw Other groups included a follow-up study of all male health professionals to supplement the study of all female nurses, and they found a small increase in diabetes risk associated with baked, boiled, or mashed potatoes, although French fries actually appeared to be about five times worse. The authors concluded that potatoes are considered a healthy vegetable in dietary guidelines, but current evidence “casts serious doubt on this classification.” Walter Willett, chairman of Harvard’s nutrition department at the time, went one step further, suggest The potatoes should be locked in there with the candy, as you can see at 2:18 below and in my video Does potato increase the risk of diabetes?.
A meta-analysis of potato consumption and risk of type 2 diabetes published All six prospective studies conducted so far in 2018 were combined, and researchers found that eating potatoes daily increased the risk of diabetes by 20%, concluding that “long-term high consumption of potatoes … may strongly influence diabetes.” Connected With an increased risk of diabetes.” But, still, most of the potatoes eaten were fried, and we know that deep-fried foods contain all kinds of nasty things, like advanced glycation end-products. The researchers were not able to assess French fries versus no-fried potatoes. Even eating fries just three times a week was associated with about a 20% higher risk of type 2 diabetes, while there was only a small risk with potatoes in general and mixed Also includes fries.
World’s largest manufacturer of frozen French fries took The issue with this conclusion. claim of It costs billions of dollars to make one in three fries eaten on planet Earth, and the company has money to finance reviews that cast doubt on the science. a review Said The scientific literature should be read carefully because the effect of potatoes on disease risk factors may depend on the foods with which they are grouped as part of the dietary pattern. In fact, they have a real issue. Observational studies can never prove cause and effect, and perhaps potato consumption – even baked potatoes – may be a marker for an unhealthy diet in general. As much as researchers try to adjust for these other factors, the journal of the Potato Association of America is also quick to remind For us, it is not possible to separate the impact of potatoes and fries from the impact of the overall poor standard American diet.
Are there any countries where potato consumption is associated with a healthy diet? If there is still an association between potato consumption and diabetes, it would be worrying. Enter the seventh study, but this time out of Iran, where most potatoes are consumed. Is Of boiled potatoes. In fact, people who ate potatoes had the healthiest diets and ate the most whole plant foods—fruits, vegetables, beans, and whole grains. And although researchers tried to tease out those other dietary factors, those who ate the most boiled potatoes were only half as likely to develop diabetes. This supports the notion that it may be difficult to isolate potatoes alone completely. Bottom line, this systematic review concludedIt’s that we don’t really have “strong evidence” that potato consumption in general is linked to type 2 diabetes, but we probably still shouldn’t consume fries.
