The Many Health Benefits Of Garlic

The Health Benefits of Garlic: Allicin, the compound in garlic, provides numerous health benefits. Fresh garlic is best as allicin breaks down after cutting. It also improves heart health, gut health, and boosts the immune system.
The numerous health benefits of garlic are well-known.

The Many Health Benefits of Garlic

We’re quite confident you already know what garlic is, so we’re going to leap straight in there with some science today:

First, let’s talk about allicin

Allicin is a compound in garlic that gives most of its health benefits. A downside of allicin is that it’s not very stable, so what this means is:

  • Garlic is best fresh—allicin breaks down soon after garlic is cut/crushed
    • So while doing the paperwork isn’t fun, buying it as bulbs is better than buying it as granules or similar
  • Allicin also breaks down somewhat in cooking, so raw garlic is best
    • Our philosophy is: still use it in cooking as well; just use more!
  • Supplements (capsule form etc) use typically use extracts and potency varies (from not great to actually very good)

Now, let’s talk benefits…

Benefits to heart health

Garlic has been found to be as effective as the drug Atenolol at reducing blood pressure:

It also lowers LDL (bad cholesterol):

Benefits to the gut

We weren’t even looking for this, but as it turns out, as an add-on to the heart benefits…

Benefits to the immune system

Whether against the common cold or bringing out the heavy guns, garlic is a booster:

Benefits to the youthfulness of body and brain

Garlic is high in antioxidants that, by virtue of reducing oxidative stress, help slow aging. This effect, combined with the cholesterol and blood pressure benefits, means it may also reduce the risk of Alzheimer’s and other forms of dementia:

There are more benefits too…

That’s all we have time to dive into study-wise today, but for the visually-inclined, here are yet more benefits to garlic (at a rate of 3–4 cloves per day):

An incredible awesome recipe using lots of garlic:

  • Take small potatoes (still in their skins), cut in half
  • Add enough peeled cloves of garlic so that you have perhaps a 1:10 ratio of garlic to potato by mass
  • Boil (pressure-cooking is ideal) until soft, and drain
  • Keeping them in the pan, add a lashing of olive oil, and any additional seasonings per your preference (consider black pepper, rosemary, thyme, parsley)
  • Put a lid on the pan, and holding it closed, shake the pan vigorously
    • Note: if you didn’t leave the skins on, or you chopped much larger potatoes smaller instead of cutting in half, the potatoes will break up into a rough mash now. This is actually also fine and still tastes (and honestly, looks) great, but it is different, so just be aware, so that you get the outcome you want.
  • The garlic, which—unlike the potatoes—didn’t have a skin to hold it together, will now have melted over the potatoes like butter

You can serve like this (it’s delicious already) or finish up in the oven or air-fryer or under the grill, if you prefer a roasted style dish (an amazing option too).

  • Stop Cancer 20 Years Ago

    Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.

    Get Abreast And Keep Abreast

    This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.

    What does she want us to know?

    Start now

    If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.

    What this means for those of us without breast cancer (or a history therof) is: start now

    Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.

    Start what, you ask? Taking away its roots. And how?

    Inflammation as the root of cancer

    To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.

    Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:

    “and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”

    So, fight inflammation now, and have a reduced risk of a lot of other woes later.

    See: How to Prevent (or Reduce) Inflammation

    Don’t settle for “normal”

    People are told, correctly but not always helpfully, such things as:

    • It’s normal to have less energy at your age
    • It’s normal to have a weaker immune system at your age
    • It’s normal to be at a higher risk of diabetes, heart disease, etc

    …and many more. And these things are true! But that doesn’t mean we have to settle for them.

    We can be all the way over on the healthy end of the distribution curve. We can do that!

    (so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)

    If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.

    So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:

    See: Focusing On Health In Our Sixties

    Fast to live

    Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.

    This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.

    See: Intermittent Fasting: We Sort The Science From The Hype

    While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.

    It’s never too late

    All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”

    The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.

    Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.

    Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
