Beneath is an approximation of this video’s audio content material. To see any graphs, charts, graphics, photos, and quotes to which Dr. Greger could also be referring, watch the above video.

In my final video on onions, I talked concerning the knowledge supporting—or not supporting—the function of onions in boosting testosterone in males, defending bone well being, controlling allergic reactions, and coping with chemo unwanted effects. What about weight reduction? Enter the impact of steamed onion consumption on physique fats in chubby topics. The researchers used steamed onions so they might higher disguise it in opposition to placebo, and dried it into onion powder and gave individuals only a miniscule quantity—about an eighth of a teaspoon a day. Certainly, a little bit day by day dusting of onion powder isn’t going to have an effect on the course of individuals’s weight, however try these outcomes, reported within the summary: a big discount in physique fats mass on each DEXA scan and measured by CT scan, a big lower within the areas of entire fats, visceral fats, and subcutaneous fats.

Maintain on. If a little bit onion powder is so efficient for weight reduction, why wasn’t it featured in my ebook How To not Weight-reduction plan? As a result of as so usually occurs in research, the spin within the summary doesn’t precisely symbolize the precise knowledge. Right here’s the DEXA scan outcomes. No important change of fats within the group that received the placebo capsules. They solely appeared to lose a couple of spoonful of fats, whereas the group unknowingly taking an eighth of a teaspoon of onion powder stuffed into capsules misplaced almost one and a half kilos of physique fats, a big drop from baseline, however not a statistically important drop in comparison with the placebo group, which means the loss may very effectively have simply been as a consequence of likelihood. Similar factor with the CT scan outcomes: 5 occasions extra lack of total fats, and 30 occasions extra lack of the harmful visceral fats, however didn’t attain statistical significance in comparison with placebo.

A more moderen examine tried 4 teaspoons of onion powder a day, and equally didn’t speed up the lack of physique fats in comparison with placebo––however the placebo was additionally 4 teaspoons of onion powder a day. They used yellow onions versus white onions, and it appears they each might have prompted a lack of physique fats, with out a important distinction between them. Both means, you may take a look at these two research and say, yeah, however what are the downsides? I imply simply an eighth teaspoon of onion powder a day. Why not give it a attempt? Can’t damage, however we simply don’t trust that it’s going to truly assist.

Turning now to polycystic ovary syndrome, also referred to as P.C.O.S., or PCOS. It’s probably the most widespread hormone issues, affecting 5 to 10 p.c of reproductive-aged ladies. Along with signs like irregular intervals, PCOS can also be a pre-diabetic state, with decreased insulin sensitivity. PCOS therapy is an enormous problem as a consequence of treatment unwanted effects. Subsequently, what about utilizing dietary choices? How a couple of randomized managed scientific trial of uncooked pink onion consumption?

Why onions? Properly, onion extracts evidently assist in diabetic rats and, extra importantly, in diabetic people, however evidently not in non-diabetic people. PCOS victims are form of pre-diabetic; so, wouldn’t it work for them? First, let’s take a look at these different two research. Right here’s the diabetic one, on the metabolic results of onion and inexperienced beans. Diabetics spent every week consuming both a small onion a day, or the identical weight loss plan however as an alternative with about 5 cups of inexperienced beans as an alternative, and so they each labored. The onion dropped individuals’s blood sugars by about 10 p.c, and the inexperienced beans extra like 15 p.c.

Right here’s the examine that supposedly exhibits no blood sugar advantages for nondiabetics. It’s true onions don’t decrease regular blood sugars, which is an effective factor, however try what occurs while you feed individuals sugar. Have individuals down about two tablespoons of corn syrup, and their blood sugars shoot up over the subsequent two hours earlier than their physique is ready to tamp it again down. However give individuals the very same quantity of sugar, however with increasingly more onion, and the blood sugar spike is considerably dampened––virtually as a lot as in the event you had as an alternative given them an antidiabetic drug. And we see the identical while you give individuals a shot of adrenaline, with…or with out…onions. So, are there blood sugar advantages for each diabetics and nondiabetics alike? No distinction was discovered between the upper and decrease onion teams of PCOS sufferers. Nor had been there any variations in a marker of irritation between the 2 teams. However ladies with PCOS aren’t simply at increased threat for diabetes and irritation, but additionally excessive ldl cholesterol.

Ladies with PCOS are seven occasions extra prone to have a coronary heart assault, the primary killer of ladies. However uncooked pink onion consumption seems to be efficient as a cholesterol-lowering meals, although the high-onion group solely dropped their LDL ldl cholesterol about 5 factors––not considerably completely different than the low onion group.

I did discover this examine from almost 50 years in the past the place researchers fed individuals almost a whole stick of butter, and their ldl cholesterol shot up about 30 factors inside hours of consumption, however solely 9 factors or three factors when mixed with a couple of third cup of uncooked or boiled onion––the ethical of the story being…don’t eat a stick of butter.
