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

In my final video on onions, I talked in regards to 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 uncomfortable side 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 folks only a miniscule quantity—about an eighth of a teaspoon a day. Certainly, a bit day by day dusting of onion powder isn’t going to have an effect on the course of individuals’s weight, however take a look at these outcomes, reported within the summary: a major discount in physique fats mass on each DEXA scan and measured by CT scan, a major lower within the areas of complete fats, visceral fats, and subcutaneous fats.

Maintain on. If a bit onion powder is so efficient for weight reduction, why wasn’t it featured in my e book How To not Weight loss 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 obtained the placebo capsules. They solely appeared to lose a few spoonful of fats, whereas the group unknowingly taking an eighth of a teaspoon of onion powder stuffed into capsules misplaced practically one and a half kilos of physique fats, a major drop from baseline, however not a statistically important drop in comparison with the placebo group, that means the loss might very properly have simply been resulting from likelihood. Identical factor with the CT scan outcomes: 5 occasions extra lack of general fats, and 30 occasions extra lack of the harmful visceral fats, however didn’t attain statistical significance in comparison with placebo.

A more moderen research 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 approach, you possibly can 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 strive? Can’t harm, however we simply don’t have faith that it’s going to really assist.

Turning now to polycystic ovary syndrome, often known as P.C.O.S., or PCOS. It’s one of the vital widespread hormone problems, affecting 5 to 10 p.c of reproductive-aged ladies. Along with signs like irregular durations, PCOS can be a pre-diabetic state, with decreased insulin sensitivity. PCOS remedy is an enormous problem resulting from medicine uncomfortable side effects. Subsequently, what about utilizing dietary choices? How a few randomized managed medical 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 type of pre-diabetic; so, would it not 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 per 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, they usually each labored. The onion dropped folks’s blood sugars by about 10 p.c, and the inexperienced beans extra like 15 p.c.

Right here’s the research 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 take a look at what occurs while you feed folks sugar. Have folks down about two tablespoons of corn syrup, and their blood sugars shoot up over the following two hours earlier than their physique is ready to tamp it again down. However give folks the very same quantity of sugar, however with an increasing number of onion, and the blood sugar spike is considerably dampened––virtually as a lot as in case you had as an alternative given them an antidiabetic drug. And we see the identical while you give folks 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 greater threat for diabetes and irritation, but in addition excessive ldl cholesterol.

Girls 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 research from practically 50 years in the past the place researchers fed folks practically a complete 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 few third cup of uncooked or boiled onion––the ethical of the story being…don’t eat a stick of butter.
