Study || Cherries Reduce Abdominal Fat?

I was eating some cherries a couple weeks ago and thought, "Hmm, I wonder if there is any research out there on cherries and fat".  Up until that point, I thought the fruit was pretty useless other than being a fix for my sweet tooth.  Well, guess what? There is research out there, one of which associates a regular intake of cherries with a reduction in abdominal fat weight, percentage fat mass, and more.  Check out the abstract: REGULAR TART CHERRY INTAKE ALTERS ABDOMINAL ADIPOSITY, ETC. (2009).

Study || Antioxidants from Artichoke and Rice Reduce UV Damage of the Hair

Extracts of artichoke and rice to protect our hair from sun damage?  While researching information for a different post, I came across a study which addresses this topic.

"Natural antioxidants obtained from artichoke and rice applied to pretreated hair improved mechanical properties and preserved colour and shine of fibres, coating them and protecting them against UV. .... Furthermore, the lipidic peroxidation of the protein degradation caused by UV was reduced for some treated fibres, suggesting an improvement in fibre integrity. "

Interesting, huh!  Here are some notes I made detailing some of the findings a bit further:

The rice extract was better at preserving the hair's tensile strength.  (It is believed that this is because "the rice extract has biofunctional peptides with high substantivity for keratin".  These peptides can "penetrate and protect the hair from the inside".) 

Both artichoke and rice extracts protected the hair from protein degradation.  The artichoke extract showed a higher protection, "probably due to the strong antioxidants such as hydroxycinnamic derivatives in the extract." 

Both artichoke and rice extracts protected the hair from UVB damage, with the rice extract providing more protection possibly due its composition. Rice extract contains phytic acid antioxidant and medium molecular weight peptides that "may form a protective layer on the hair's surface."

Etc.

Study || Herbal Oils as a Natural Sunscreen?

According to quite a few studies, certain herbal oils can provide a level of protection from the sun.  The calculated SPF values range from 0.248 to 7.549.  Olive oil and coconut oil are among the highest ranking ones.

Now, though these oils provide some sun protection, I would not go so far as to use them in place of a regular sunscreen.  After all, many dermatologists recommend that women of color wear a sunscreen with an SPF of 15 or even 30.  Olive oil and coconut oil have an SPF of only 7.5 and 7.1, respectively.  Some of these oils, however, can decelerate damage caused to the skin after sun exposure ... which is something that sunscreens generally do not do.   (Check out my earlier post on olive oil after UVB-exposure.)  Additionally, these oils can provide our hair with a level of sun protection. :o)

Study || Oil vs. Butter for Gloss, Combing, and Reduction in Split Ends

Many of us already know that in order to avoid breaking, dull hair we need some form of moisturization (i.e., water followed by an oil/butter/cream).  However, if we are just discussing oils and butters, which group is actually better for our hair?

A 2009 study on oils (Brazilian nut, mineral oil, passion seed, palm olein, buriti, palm stearin) and butters (ucuúba, sapucainha, tucumã) demonstrated that the former may be the better option when it comes to combing ease, gloss, and reduction in split end formation.  This conclusion is linked to the "molecular chain conformation" of triglycerides in oils versus in butters.  The triglycerides in the butters studied have more branches and higher melting points, both of which may increase friction and thus decrease the ease of spreading.  What does this mean in plain English?  Well, think of it this way: Because butters are harder to spread on the hair, they may not be as effective as oils in terms of combing ease, luster, and minimizing split ends.  (Some of you are probably saying "Duh!!" right now simply based on just experience.  Lol.)

Another conclusion from the study is that ucuúba butter improves the tensile strength of hair -- which is something that all the other oils and butters studied did not do.  The thought is that the low molar mass triglycerides of ucuúba butter are able to penetrate into the hair (you know, like coconut oil).

So, in short, choose the oil over the butter if you want more sheen + less breakage and splits.

Study || Palm Oil + Conditioning Damaged Hair

Damaged hair has a higher degree of swelling in water than relatively healthy hair.  Because of this increase in swelling, damaged hair will experience even more damage.  According to a 2012 study, hydrogenated palm oil is effective at preventing water-induced swelling of damaged hair, possibly because it can "penetrate into the cuticle and outer cortex" of said hair.

Study || Olive Oil, Antioxidant Power, and Skin Protection

A 2000 study suggests that topical application of virgin olive oil after UVB exposure can reduce UVB-related skin tumors.  The thought is that the antioxidant power of the oil is responsible for this benefit.  (Extra virgin olive oil is said to have a "potent antioxidant effect".)

Studies || Argan Oil + Hyperpigmention, Oily Skin and Cardiovascular Health

Argan oil is the new "it" oil in the hair care community.  Ladies are talking about it online.  Companies are including it on the labels of their conditioners and shampoos.  Many of us have heard about it.

Well today, putting hair care aside, let us look at argan oil in skin care and overall body care.  Here are a few findings worth mentioning:

• Argan oil may be effective against hyperpigmentation disorders (e.g., acne scarring).
• Extract from saw palmetto and sesame seeds in an argan-oil base was shown to control oily skin.
• Findings suggest that regular consumption of argan oil can lower "bad cholesterol" (i.e., LDL cholesterol).

Study || Oil Pulling + Oral Health

Oil pulling is an old Ayurvedic practice that consists of gargling with (or holding a mouthful of) oil for several minutes to detoxify the body thus eliminating many health issues.  Some of us have heard about it.  Some of us practice it.  But is there any research that shows its efficacy against health issues?  Well, while I could find nothing concerning the effectiveness of oil pulling against migraines, diabetes, asthma, and many other claimed health benefits, I did find a study involving oral health.

This study was conducted back in 2008 with the use of sesame oil, to be exact, and 10 minutes of gargling daily for two weeks.  So what was the conclusion?  Oil pulling prior to brushing was effective in reducing bacteria related to tooth decay (specifically the Streptococcus mutans that was found in plaque).  Thus, oil pulling can be used "as a preventative home therapy to maintain oral health" [1].

Studies || Avocado Oil on the Skin + Collagen and Wounds

Avocado oil is a fairly popular oil used in the natural hair community.  It is great for sealing in moisture and enhancing conditioners.

But what about avocado oil on the skin?  Well, a few studies have demonstrated that this oil can increase soluble collagen (when consumed) AND help to heal wounds better than petroleum jelly (when applied topically).  Check out the abstracts below:

Study || Turmeric vs. Prozac for Depression

A recent study has demonstrated that curcumin, which is found in turmeric, may be an effective treatment for individuals with major depressive disorder (without "suicidal ideation or other psychotic disorders"[1]).  The blind study evaluated three groups - those taking fluoxetine (also known as Prozac), those taking curcumin, and those taking a combination of the two.  Hmm ... could the day be near when turmeric is widely used to treat depression?  Check out the study for yourself:

Study || Food-Packaging Chemical (DEHP) + Diabetes Risk in Children

Check out the following excerpts from recent research on DEHP (a food-packaging chemical) and diabetes precursors in adolescents:

MOTIVATION

"Mono-(2-ethylhexyl) phthalate (MEHP), a DEHP metabolite, activates peroxisome proliferator-activated receptor(PPAR) g transcription more selectively than rosglitazone,[12] a drug used to treat type 2 diabetes by increasing insulin sensitivity.[13] This selective upregulation appears to explain the differential effects of rosglitazone and MEHP, in which MEHP produces a phenotype of insulin resistance in cellular models,[14,15] and in vivo.[16] Given that PPAR plays key roles in lipid and carbohydrate metabolism,[17] these findings provide biological plausibility for DEHP metabolites in insulin resistance. ..."

BACKGROUND
"Di-2-ethylhexylphthalate (DEHP) is an environmental chemical commonly found in processed foods [and food packaging]. Phthalate exposures, in particular to DEHP, have been associated with insulin resistance in adults, but have not been studied in adolescents."

CONCLUSION
"Urinary DEHP concentrations were associated with increased insulin resistance in this cross-sectional study of adolescents. This study cannot rule out the possibility that insulin-resistant children ingest food with higher phthalate content, or that insulin-resistant children excrete more DEHP."

Study || Grapeseed Oil and Removal of Sun-Induced Hyperpigmentation?

When the summer hits, my face begins to tan more quickly than the rest of my body (because it is more exposed).  I usually do not have a problem with this tanning variation except when it comes to matching foundation or wearing low-cut tops that reveal a less tanned complexion from the neck down.   I've learned to deal with it since it is only temporary, and during some summers, the tan does balance out over time.

Nevertheless, I stumbled upon this interesting study (while researching grapeseed oil) that demonstrated lightening effects on UV-induced hyperpigmentation (i.e., a tan) after topical application of linoleic acid.  Since grapeseed oil contains a large amount of linoleic acid, it makes you wonder if it would have that effect?  Maybe you can do your own personal experiment or research.

Study || Hard Water Impact On Hair

Hard water metals concentrate primarily in the cuticle layer.  A study published in 2011 indicated that these metals can affect certain hair properties, which include:

- stiffening of hair strand
- reduction of combing forces
- improvement of ability to hold a style in virgin hair
- reduction of ability to hold a style in bleached hair

Additionally, certain variables affect the uptake of hard water metals by the hair, such as the:

- condition of the hair (e.g., chemically damaged)
- pH of the water
- level of water hardness

Study || Water Vs. Coconut Water Vs. Sports Drinks

A study published in early 2012, demonstrated little difference between four beverages with regard to rehydration and subsequent support of exercise.  The four tested beverages included: 1) bottled water, 2) pure coconut water, 3) coconut water from concentrate, and 4) a carbohydrate-electrolyte sports drink.

So then what is a good reason to choose coconut water and/or bottled water over a sports drink?  Well, there are more than one:

1. Pure coconut water generally has fewer calories than sports drinks.  Moreover, bottled water has no calories.  
2. If you are looking for a natural alternative to sports drinks, coconut water and bottled water are two options.  
3. If you are wanting to lower sodium in your daily diet, pure coconut water and bottled water (which is even better) are the way to go.  
4. If you want to increase your potassium intake, pure coconut water is the best of the above options.  (Coconut water contains approximately 12x more potassium than Gatorade.)

AN IMPORTANT PART OF THE CONCLUSION: "Additional study inclusive of a more demanding dehydration protocol, as well as a time trial test as the measure of exercise performance, may more specifically determine the efficacy of these beverages on enhancing hydration and performance following dehydrating exercise."  (For the above study, twelve exercise-trained men were subjected to 60 minutes of treadmill exercise.)

Case Study || "Tangle-Teezer-Like" Tool and Breakage?

I was on one of my favorite forums when I came across the following case study that was performed in India.  The report involves a tool that resembles the "Tangle Teezer" in terms of bristle arrangement and sizing.  (There are, of course, some differences between the tool in the report and the "Tangle Teezer", but the similarities cannot be neglected, in my honest opinion.)

So what is so interesting about this case study?  Well, to me, it does more than demonstrate how the use of certain hair tools may ultimately translate to breakage.  It does two more things:

1) It gives possible confirmation to those who jumped on the "Tangle Teezer" bandwagon and noticed an increase in breakage and split ends thereafter.

2) And, for my own hair care practices, it makes me think twice about using the "Tangle Teezer" on my flat-ironed hair.  (You see, I figured the problem with the tool that most people were experiencing was due to using it on textured hair.  I thought it okay to use the tool on straight hair ... until now.)  Contrary to what I initially guessed, the study was performed on patients who were not afro-textured but who had naturally straight/wavy hair.  Even on straight hair, this tool may present a problem!?!

Ultimately, patients were asked to: 

• avoid the tool (and instead use a straight comb with elongated bristles) AND 
• to change their combing habits (which involved using the tool on hair that had not been lubricated with conditioner or oil).

Study || Almond Oil Massage for Stretch Marks

Some of you have probably heard that application of cocoa butter (during pregnancy) reduces the likelihood of developing stretch marks.  Well according to a few studies published a few years ago, cocoa butter does not appear to be effective like some believe [1][2].

So how about olive oil?  Well, a study published last year does not support the application of olive oil as being effective either [3].

So what oil/butter might work then?  Research does support is that massaging with almond oil may reduce the development of stretch marks [4].

Skin Care || Mederma vs. Vaseline for Scar Healing

If you have ever searched high and low for a cream that improves the appearance of scars, then you are probably familiar with Mederma, which is expensive.  Well, you will be happy (or upset after having spent that much money) to know that it is no more effective than petroleum jelly at scar healing.  More importantly, keeping the "wound moist and covered[1]" via petroleum jelly or another topical treatment will minimize scarring period.

So before you shell out that money for Mederma, turn to your good old Vaseline to minimize the appearance of scars.

Healthy Eating || Bananas and Lowering Blood Pressure

Lately my blood pressure has been lower than usual, which isn't a bad thing at all in this case.  The systolic pressure normally ranges between 101 and 110 while the diastolic pressure between 65 and 80.  However, my two most recent tests were 91/60 and 93/57. I don't recall my blood pressure ever being this low ... at least not in recent years.

So, I thought to myself, "What have I been doing differently?"  And then it occurred to me, "Well, I've been eating a lot of bananas [in smoothies].  Could that be it?"  Then I went to the internet, did some digging, and learned that there are dozens of references to the high potassium in bananas helping to lower blood pressure.  Here are a couple of abstracts worth reading:

Healthy Eating || Becoming a Tea Drinker

I've never been a tea drinker (and, I mean never), but in mid-October, I decided to get to work on some tea I purchased under hypnosis.  (Okay, maybe I wasn't under hypnosis, but I was under something I guess.)  The tea is actually really good quality and tastes exquisite relative to your average store-bought tea.  However, what I also like about it are the health benefits.  For me, the biggest one I am noticing within myself is the stress reduction.

Below is an excerpt of the article on WebMD.  Full article: TEA TYPES AND THEIR HEALTH BENEFITS

• Green tea: Made with steamed tea leaves, it has a high concentration of EGCG and has been widely studied. Green tea’s antioxidants may interfere with the growth of bladder, breast, lung, stomach, pancreatic, and colorectal cancers; prevent clogging of the arteries, burn fat, counteract oxidative stress on the brain, reduce risk of neurological disorders like Alzheimer’s and Parkinson’s diseases, reduce risk of stroke, and improve cholesterol levels.
• Black tea: Made with fermented tea leaves, black tea has the highest caffeine content and forms the basis for flavored teas like chai, along with some instant teas. Studies have shown that black tea may protect lungs from damage caused by exposure to cigarette smoke. It also may reduce the risk of stroke.
• White tea: Uncured and unfermented. One study showed that white tea has the most potent anticancer properties compared to more processed teas.
• Oolong tea: In an animal study, those given antioxidants from oolong tea were found to have lower bad cholesterol levels. One variety of oolong, Wuyi, is heavily marketed as a weight loss supplement, but science hasn’t backed the claims.
• Pu-erh tea: Made from fermented and aged leaves. Considered a black tea, its leaves are pressed into cakes. One animal study showed that animals given pu-erh had less weight gain and reduced LDL cholesterol.

Another article (excerpt below): TEA BENEFITS

Studies of humans, animals, and petri-dish experiments show that tea is high beneficial to our health. Research suggests that regular tea drinkers -- people who drink two cups or more a day -- have less heart disease and stroke, lower total and LDL cholesterol, and recover from heart attacks faster. There's also evidence that tea may help fight ovarian and breast cancers.

Tea also helps soothe stress and keep us relaxed. One British study found that people who drank black tea were able to de-stress faster than those who drank a fake tea substitute. The tea drinkers had lower levels of cortisol, a stress hormone.

Beet Juice, Beet Smoothie: Blood Pressure & Stamina

Don't sleep on beet juice. Studies performed over the past several years suggest that drinking beetroot juice may lower blood pressure and thus have implications for the treatment of cardiovascular disease.  What is the underlying cause of this lowering of blood pressure?  It is the nitrate content of beetroot.  Additionally, other studies suggest that this juice boosts stamina, which can prolong exercising.

So how does one incorporate this vegetable into one's diet?  Well below is a recipe for a delicious, beet smoothie.  As always, please consult with your doctor before adjusting your diet or lifestyle.
