Benefits of Rosemary for Brain Function in Hamlet, Act, 4, Scene, 5, Ophelia notes that rosemary is for remembrance, an idea that goes back at least a few thousand years to the ancient Greeks who claimed that rosemary comforts. The brain sharpens understanding, restores lost memory and awakens the mind. After all, plants can be considered little chemical factories that manufacture all sorts of compounds that could have neuroprotective benefits.
So let’s cut down on processed foods and eat lots of phytonutrient-rich whole plant foods, including perhaps a variety of herbs.
Even the smell of certain herbs may affect how our brain works.
Unfortunately, I’ve found much of the aromatherapy literature scientifically unsatisfying, like there’d, be studies like this, offering subjective impressions and so fine sure sniffing.
An herbal sachet is indeed easy, inexpensive, and safe, but is it effective? They didn’t compare tests, scores, or anything Even when there was a control group where researchers had people do a battery of tests in a room that smelled like rosemary, lavender, or nothing, and even when they did compare test results.
The lavender appeared to slow them down, and impair their performance, whereas the rosemary group seemed to do better, But maybe that’s just because of the mood effects.
Maybe the rosemary group did better just because the aroma kind of pepped them up And not necessarily in a good way, maybe kind of overstimulating.
In some circumstances, there have been studies that measured people’s brain waves and were able to correlate the EEG findings with the changes in mood and performance, along with objective changes in stress hormone levels.
But is this all just because pleasant smells improve people? S moods Like if you created some synthetic rosemary fragrance with a bunch of chemicals that had nothing to do with the rosemary plant.
Would it still have the same effect We didn’t know until now that aromatic herbs do have volatile compounds that theoretically could enter the bloodstream by way of the lining of the nose or lungs and then potentially cross into the brain and have direct effects? But this was the first study to put it to the test.
They had.
People do math in a cubicle infused with rosemary aroma, and so yes, they got that same boost in performance, but for the first time showed how much better they did correlate with the amount of a rosemary compound that made it into their bloodstream.
Just from being in the room, and so not only did this show that it gets absorbed, but that such natural aromatic plant compounds may be playing a direct effect on changes in brain function.
If that’s just what smelling it can do? What about eating rosemary? We have studies on alertness and cognition and reduced stress hormone levels, by inhaling rosemary.
However, there were no clinical studies on cognitive performance following ingestion of rosemary.
Until now, Older adults, average age 75 were given two cups of tomato juice, with either nothing or a half.
A teaspoon of powdered rosemary, which is what one might use in a typical recipe, or a full teaspoon, two teaspoons, or over a tablespoon of rosemary powder, and they even gave them some placebo pills to go with it to even further eliminate any placebo effects.
Speed of memory is a potentially useful predictor of cognitive function during aging, and what they found is that the lowest dose had a beneficial effect, accelerating their processing speed, but the highest dose impaired their processing speed, maybe because the half-teaspoon dose improved alertness, while the 4 Teaspoon dose decreased alertness, So rosemary powder at the dose nearest to normal, culinary consumption demonstrated positive effects on speed of memory.
The implicit take-home message being more isn’t necessarily better. Take high doses of herbal supplements extracts tinctures, just cooking with spices is sufficient.
A conclusion, no doubt pleasing to the spice company that sponsored the study.
No side effects were reported, but that doesn’t mean you can eat the whole bush.
This poor guy swallowed a rosemary twig which punctured through the stomach into his liver, causing an abscess from which 2 cups of pus and a 2-inch twig were removed, so explore herbs and spices in your cooking Branch out.
Just leave the branches out.

“Yoga Put to the Test for Headaches,
Diabetes, Osteoarthritis, and the Elderly” Yoga is an ancient mind-body
discipline which originated in India thousands of years ago, and that’s where most yoga
studies are done to this day. This has raised concerns
that national pride might incline Indian researchers
to quietly shelve any negative results and just publish studies
showing yoga works. This fear is not without precedent. For example, research conducted in
China, Japan, Hong Kong, and Taiwan were found to be uniformly
favorable to acupuncture; all trials, without exception,
were positive.
Now, one possible explanation
for this finding is that acupuncture is just
more effective in countries where it is traditionally practiced,
but it’s a little suspicious. So, are Indian yoga trials
more likely to be positive than those from other countries? They looked at hundreds of
Randomized controlled trials of yoga, both done in India and
done in other countries, and trials on yoga conducted in India
had about twenty-five times the odds of reaching positive conclusions
as those conducted elsewhere. Again, yes, yoga might be more
effective in India than elsewhere, but it is a little suspicious. So, for example, if you’re interested
in whether yoga is helpful for treating headaches,
and you read that yoga appears to be helpful
For those suffering from tension-type headaches,
but then you find out that nearly all such studies were
conducted in India, what do you do
with that information? Also, notably, none
of the control groups had any sort of exercise component,
though this may be less critical for tension headaches, since
neither aerobic exercise training…
Nor does strength training
appear to help them. So, if we’re to believe
the Indian study conclusions, yoga may indeed help
with tension headaches, but even they found
no effect for migraines. What may help migraines,
though, are other types of exercise, specifically aerobic exercise,
decreasing migraine pain intensity, frequency, and duration,
at least in the short term. What about the benefits
of yoga practice compared to physical exercise
in the management of type 2 diabetes? A significant reduction
in both short-term and longer-term blood sugar control
was noted in the yoga groups compared to other
exercise control groups.
However, the findings may need
to be interpreted with caution, since nearly half of the studies
didn’t define and adhere to a well-planned exercise regimen
in the control group. Furthermore, an exercise intervention
comparable in intensity to yoga was followed only in three
out of the eight studies included. And, for what it’s worth,
The majority of the studies, six out of eight, were from India. When yoga was carefully
compared to sham yoga, which consisted of chair exercises,
standing exercises, and slow walking to match
the yoga session, the relative yoga
benefits evaporated.
Both yoga and sham yoga had identical effects
on blood sugar status. Hence, further well-controlled
Randomized trials are required prior to drawing conclusions
about the benefits of yoga in comparison to physical exercise
in patients with diabetes. Similar tentative conclusions were
reached for yoga for osteoarthritis. Put all the studies together
and yoga may indeed be effective for improving pain, function,
and stiffness in individuals with osteoarthritis of the knee,
compared not only to doing nothing but compared
to other kinds of exercise. They had some issues with
the quality of some of the studies, and so only a weak recommendation
for the use of yoga for osteoarthritis, but hey, if you like yoga or if yoga
is the only kind of exercise you’re willing to do, then
It’s probably better than nothing. Finally, in this video,
Let’s look at the effects of yoga compared to active and inactive
controls meaning like compared to other exercise regimens
or just like doing nothing on physical function and
health-related quality of life in adults aged 60 and older. Compared to doing nothing,
They found clear evidence that yoga improves physical function
and psychological well-being in older adults, so it definitely
better than nothing.
What about compared
to other exercises? Yoga pulled ahead for lower limb
strength and lower body flexibility, but for improving balance,
mobility, and walking speed, yoga appeared comparable. Psychologically, yoga appeared
to beat out other exercises for alleviating depression
in older adults, but not anxiety or perceived
mental health in general.

“Fruits and Vegetables Put
to the Test for Boosting Mood,” There are two components of
psychological health: the absence of mental health disorders
such as depression, as well as the existence of positive
psychological well-being. That’s the focus of an emerging
field of positive psychology focusing on happiness, life
satisfaction, and flourishing, which may translate to physical
benefits such as improvements in blood pressure, immune
function, and longevity. What is the contribution of food
consumption to well-being? Well, studies have linked the
consumption of fruits and vegetables with enhanced well-being.
A systematic
review of research found evidence that consuming fruits and
vegetables were associated with increased psychological well-being.
Okay, but that’s just an association. A famous criticism in this area of
research is that maybe there’s just some inherent personality trait
or type of family upbringing that might lead people simultaneously to eat healthily, and also
to have better mental well-being. So the diet is merely correlated
with, but incorrectly gives the appearance of helping to
cause the level of well-being.
But recent research circumvented
this problem by seeing if changes in diet are correlated
with changes in mental well-being, in effect studying the evolution
of well-being and happiness after increases in the consumption
of fruits and vegetables. And look at that graph—a straight-line
increase between how much more fruits and veggies people started eating
and their change in life satisfaction over time. Increased fruit and
vegetable consumption appeared predictive of increased happiness,
life satisfaction, and well-being— up to 0.24 life satisfaction points for
an increase of eight portions a day. What does that mean?
Is that a lot? Is that a little? That’s a lot, equal in size
to the psychological gain of going from being unemployed
to get a job.
My Daily Dozen recommendation
is for at least nine servings of fruits and veggies a day. This study was done in Australia.
It was repeated in the UK, and researchers there found the same
thing, though the Brits may need to bump up their daily minimum to
more like 10 or 11 servings a day. Okay, but does eating fruits and veggies
also reduce the risk of depression and anxiety? I mean
well-being is nice, but governments and medical
authorities are often interested in the determinants of major
mental illness, not life satisfaction. And indeed, using the same data set
but instead looking for mental illness, eating fruits and vegetables may
help to protect against future risk of clinical depression
and anxiety as well. A systematic review and meta-
analysis of dozens of studies found that every 100-gram increased intake of
fruit was associated with a 3% reduced risk of depression. That’s about
half an apple, yet less than 10% of most Western populations
even consume a bare minimum. Maybe the problem is we’re just telling
people about the long-term benefits of fruit intake for chronic
disease prevention, rather than the near-immediate
improvements in well-being.
So maybe we should be advertising
the happiness gains, but first, we need to
make sure they’re real. We’ve been talking about associations.
Yes, a healthy diet may reduce the risk of future depression or anxiety, but
being diagnosed with depression or anxiety today could also lead
to lower fruit and vegetable intake. Now, in these studies, you can
indeed show that the increase in fruit and vegetable consumption came
first, and not the other way around, but as the great enlightenment
philosopher pointed out, just because the cock
crows before the dawn doesn’t mean the cock
caused the sun to rise. To prove cause-and-effect you need to put it to the test
with an interventional study. Unfortunately, to date, many
studies were like this, where those randomized to eat fruit
showed significant improvements in anxiety and depression, fatigue,
and emotional distress.
Wow, amazing! But that was compared
to chocolate and potato chips. Apples, clementines, and bananas
making people feel better than assorted potato chips and chunky chocolate
wafers—not exactly a revelation. This is the kind of study I’ve been
waiting for: a randomized controlled trial in which young adults were
randomized to a diet-as-usual group, encouraged to eat
more fruits and veggies or a third group was given two servings
of fruits and vegetables a day to eat over and above
their regular diet.
And the ones given fruits and
veggies showed improvements in their psychological well-being
with increases in vitality, flourishing, and motivation within just two weeks! However, simply educating people
to eat their fruits and vegetables may not be enough
to reap the full rewards, so perhaps greater emphasis needs to
be placed on actually providing people with fresh produce, for example, offering
free fruit for people when they shop.
I know that would certainly
make me happy!

Dr. Greger visited Google NYC to discuss his new book – How Not to Die.
The vast majority of premature deaths can be prevented through simple changes in diet and lifestyle. In How Not to Die, Dr. Michael Greger, the internationally-recognized lecturer, physician, and founder of NutritionFacts.org, examines the fifteen top causes of death in America—heart disease, various cancers, diabetes, Parkinson’s, high blood pressure, and more—and explains how nutritional and lifestyle interventions can sometimes trump prescription pills and other pharmaceutical and surgical approaches, freeing us to live healthier lives.
The simple truth is that most doctors are good at treating acute illnesses but bad at preventing chronic disease. The 15 leading causes of death claim the lives of 1.6 million Americans annually. This doesn’t have to be the case. By following Dr. Greger’s advice, all of it backed up by peer-reviewed scientific evidence, you will learn which foods to eat and which lifestyle changes to make to live longer.
History of prostate cancer in your family? Put down that glass of milk and add flaxseed to your diet. Have high blood pressure? Hibiscus tea can work better than a leading hypertensive drug—and without the side effects. What about liver disease? Drinking coffee can reduce liver inflammation. Battling breast cancer? Consuming soy is associated with prolonged survival. Worried about heart disease (our #1 killer)? Switch to a whole-food, plant-based diet, which has been repeatedly shown not just to help prevent the disease, but arrest and even reverse it.
In addition to showing what to eat to help prevent the top 15 causes of death, How Not to Die includes Dr. Greger’s Daily Dozen—a checklist of the foods we should try to consume every day. Full of practical, actionable advice and surprising, cutting edge nutritional science, these doctor’s orders are just what we need to live longer, healthier lives.
