Ought to we be involved in regards to the pimples, cadmium, and “colonic crunch” related to the consumption of sunflower seeds?
A current observational examine on pimples reported a “statistically vital relationship” between “pimples severity and dietary elements corresponding to chocolate, dairy merchandise corresponding to milk, [and] sunflower seed consumption….” I’ve produced movies on pimples and chocolate and dairy, however I used to be stunned by the sunflower seeds, the subject of my video Do Sunflower Seeds Trigger Zits?.
Once I take into consideration sunflower seeds, I simply consider a very good, whole-food supply of diet that’s been discovered to decrease levels of cholesterol as a lot almonds, which is fairly good. However do you know there are proper and mistaken methods to eat them? Should you eat a pound of unshelled sunflower seeds—that’s, eat them with the shell nonetheless on—you may find yourself corked with “a fist-sized mass of shredded sunflower seed shells.” How may a health care provider diagnose one thing like that? By the “‘colonic crunch’ signal,” after all. Seems like breakfast cereal served in hell, however, relatively, it’s the “palpation of a giant crunchy rectal mass.” You may see a photograph of 1 at 1:10 in my video.
Certainly, for those who eat sunflower seeds with the shells nonetheless on, you can find yourself with a “sharp, thorny mass,” which is why the so-called sunflower seed syndrome has been described as “a prickly proctological downside.” It’s been lamented that “individuals who eat well being meals often fall into the entice of believing ‘if some is sweet, extra is best.’” On this case, it’s not the quantity that’s the issue, however how they’re being eaten: with the shells nonetheless on. “Maybe this is the reason the syndrome is unusual until the sufferers are kids or adults who’re both impaired or haven’t any expertise with consuming sunflower seeds.”
Most circumstances contain youthful, “preadolescent kids,” aged 5 to 11, however researchers described the case of a “psychologically sound” 13-year-old woman and “careworn the significance of the function of the dad and mom guiding their kids, regardless of the age group, in regards to the potential issues related to the ingestion of unshelled seeds.”
Does that imply you may eat as many sunflower seeds as you need so long as they’ve been shelled? No—you may overdo even shelled seeds. Merely due to the character of sunflowers, they’re good at drawing the naturally occurring heavy metallic cadmium out of the bottom. So, even when they’re grown in uncontaminated soils, sunflower seeds (or kernels) find yourself with larger cadmium ranges than most meals. Nevertheless, individuals who eat giant quantities of sunflower seeds don’t appear to undergo any untoward results and even find yourself with detectably larger cadmium ranges. What constitutes a “giant” quantity? On this examine, it was outlined as greater than an oz per week, which is sort of a handful, about 150 seeds.
The World Well being Group recommends staying under about 490 micrograms of dietary cadmium per week. Should you ate a handful of shelled sunflower seeds a day, you’d be effectively under that, however we might get as a lot as 36 micrograms a day from the remainder of our weight loss program, so I believe one handful a day is an affordable protected higher restrict.
Okay, however will sunflower seeds give us pimples? You don’t know, till you set it to the take a look at, which researchers did as a result of, in any case, “consuming sunflower seeds is a really gratifying method of collaborating in a medical trial….” Fifty younger adults have been randomized to eat sunflower seeds—or not—for per week. As you may see at 3:23 in my video, the pimples severity index stayed about the identical within the management group, however received worse within the sunflower group. This translated into about three additional pimples within the sunflower seed group versus solely about one additional pimple within the management group. The researchers concluded that “sunflower seed consumption seems to irritate pimples vulgaris; nevertheless, additional proof is required to ban sunflower seed consumption in sufferers with pimples.”

- Researchers reported a “statistically vital relationship” between pimples severity and chocolate, dairy merchandise, and sunflower seed consumption. When put to the take a look at, the pimples of examine individuals within the sunflower group worsened in comparison with these within the management group, main the researchers to conclude that consumption of sunflower seeds seems to irritate pimples vulgaris. Nevertheless, extra proof is required to ban sufferers with pimples from consuming sunflower seeds.
