Strawberries: A Sweet, Vitamin-Rich Health Support
"The taste of a warm, juicy strawberry on a hot summer day is a delight to the mouth," wrote Lori Glenn, Managing Editor. "Even in February when southern California strawberries appear at the northern California farmer's markets, the sight of the red fruit is a joy they promise that better weather and a variety of berries will soon appear."
A signal of spring and summer to come, strawberries are not only sweet, their nutrient-rich too, as Glenn goes on to explain:
"Strawberries are a rich source of flavonoids, iron, folate, potassium, vitamins B, C and E, and phenols. In the strawberry, these phenols are led by anthocyanins and ellagitannins. The anthocyanins not only provide the strawberry's red color, but they also supply antioxidants. Strawberries' unique phenol content gives them heart-protective, anti-cancer, and anti-inflammatory abilities. Strawberries also have blood-purifying, astringent, diuretic, and liver-tonic properties. Medicinally, the fruit has been used to treat anemia, constipation, fevers, hangover, high blood pressure, gout, and rheumatism. Cut strawberries have even been used to whiten teeth and are said not to damage the enamel. In a recent study (see HC 110195-396), freeze-dried strawberries were found to lower cardiovascular disease risk factors in women with metabolic syndrome."
Eat up! Glenn suggests adding strawberries to a green salad with the addition of some chopped nuts and cheese drizzled with lemon and olive oil. How do you like your strawberries? If you have favorite, healthy strawberry recipes to share, please post them here!!
Also, yesterday's edition of The Oregonian included the article "Growing strawberries is deliciously easy here." According to the article, Oregon's climate is perfect for strawberries, but even if you don't live near ACHS in Oregon, there may be some use useful tips about planting, care, and harvest as well.

Health Benefits of Parsley Featured in Psychology Today
The April edition of Psychology Today magazine includes an insightful profile of parsley, commonly thought of as "The Garnish Herb."
As the article by Hara Estroff Marano[1] points out, parsley actually has quite a few nutrients, including beta carotene, vitamins B12 and folate, and "more vitamin C than the equivalent amount of orange." In addition, parsley "contains immunity-enhancing phytonutrients like luteolin that curb inflammatory processes in the body," and other organic compounds, including myristicin and folic acid.
Perhaps our most well-known garnish, in other parts of the world parsley serves a heartier function. Leafy and a bit whispy, parsley can be used to make several sauces, including pesto, and is added to many grain and salad dishes, such as tabbouleh.
Plus, the rumors are true ... parsley does help freshen breath after eating more pungent foods like garlic!
Here's a link to a study[2] about how the antioxidant capacity of culinary herbs, including parsley, is affected by various cooking and storage processes: http://www.ncbi.nlm.nih.gov/pubmed/18224444

Highlights from "What is Aromatherapy?" at the Lan Su Chinese Garden in Portland
Have you seen our new photos on Facebook? Click here to see photos from today's lecture "What is Aromatherapy?" at the Lan Su Chinese Garden in downtown Portland, Oregon.
Check out our new photo album “What is Aromatherapy? at the Lan Su Chinese Garden” from ACHS President Dorene Petersen’s lecture today.
Most of the photos are from within the Scholars’ Room, where the lecture took place, but there is also a beautiful picture of a big rhododendron right outside the lecture hall, in the Fragrance Garden.
For those of you who weren’t able to attend in person today, Dorene is going to give a complementary aromatherapy lecture at the Garden next week, on March 30, at 1pm, which is a continuation of the Garden’s Festival of Fragrance.
But, don’t worry if you’re not able to attend that event either, we filmed it! “What is Aromatherapy?” will be available for download on our College channel, ACHStv, on YouTube soon. Here is a link: http://www.youtube.com/ACHStv It’s easiest to subscribe to ACHStv and an email will automatically be sent to you when the video is available (and all educational holistic health videos we post for free download!).
In the meantime, here are some interesting points from Dorene’s lecture:
- Aromatherapy is the use of aromas for their healing properties.
- An essential oil is the distilled (or sometimes expressed) product of the volatile components synthesized by various plant tissues of a single plant species.
- Essential oils are produced in different parts of the plant depending on the oil. Some examples include: Fennel (Foeniculum vulgare) is from seeds; eucalyptus (Eucalyptus globulus) from leaves; and bitter orange (Citrus sinensis) is from the peel.
Some essential oils you might want to get started with include (note, before apply essential oils to the skin, a skin patch test is recommended):
- Peppermint (Mentha piperita), which is attributed with antiseptic, germicidal, and antibacterial properties.
- Lavender (Lavandula officinalis), which is attributed with soothing, balancing, and antibacterial qualities.
- Sweet orange (Citrus sinensis), which is attributed with antidepressant and anti-inflammatory properties.
>> All of these essential oils, as well as a large variety of additional oils and organic base oils (including camellia, aloe vera, and jojoba) can easily be ordered from ACHS’s Apothecary Shoppe College Store here: www.apothecary-shoppe.com. Just click on Essential Oils and/or Carrier Oils on the left-hand toolbar.
Two parting thoughts: First, when you have a quiet moment to yourself, ponder these words from Helen Keller: “Smell is a potent wizard that transports us across thousands of miles and all the years we have lived.”
Second, the Moon Gate at the Garden has a plaque above the arch on each side. On one side it reads, “Read the landscape,” and on the other side, “Listen to the fragrance.” According to the Lan Su Chinese Garden’s website, “In Chinese tradition, garden landscape without poetry is not complete.”
What do the words “Listen to the fragrance” whisper to you? We’d love to hear your thoughts!

Healthcare Reform Bill Passed March 21 to be Signed by President Obama
More than 30 million Americans will now have access to healthcare. The $940 billion bill will "extend health coverage to most Americans," as reported on NPR. "Medicaid, the federal-state program that provides health insurance to the poor and disabled, will be expanded to cover all adults earning less than 133 percent of the federal poverty level."
Additional highlights of the healthcare bill include:
- Individuals and small companies will have access to private health insurance via exchanges run by the states
- Those who do not buy insurance, and "most employers who do not offer coverage to workers," face fines
- "All but about 5 percent of non-elderly Americans will ultimately be covered"--about half through Medicaid and half through private insurance
- "There will be a broad education effort, so that people understand what's in the legislation," said Executive Director of Families USA Ron Pollack
- The Congressional Budget Office "has estimated that the legislation will reduce the federal deficit by $143 billion over the next 10 years"

NPA Natural Standard for Home Care Products
The Natural Products Association has developed the Natural Products Association Standard and Certification for Home Care Products, which will help "protect and equip consumers to maximize their well being," according to the NPA website.
The NPA describes their Certification as "guidelines that dictate whether a product can be deemed truly 'natural,'" and includes home care products like household cleaners, laundry detergents, and ready-to-use hard-surface cleaners. Certified products would bear the NPA natural home care seal.
As outlined on the NPA website, establishing a standard for natural home care products would help ensure:
- Natural Ingredients: A product labeled "natural" should be made up of only, or at least almost only, natural ingredients and be manufactured with appropriate processes.
- Safety: A product labeled "natural" should avoid any ingredient that has peer-reviewed, scientific research showing human health or environmental risk.
- Responsibility: A product labeled "natural" should use no animal testing in its development except where required by law.
- Sustainability: A product labeled "natural" should use biodegradable ingredients and the most environmentally sensitive packaging.
- Product must be made up of at least 95 percent truly natural ingredients or ingredients that are derived from natural sources, excluding water
- No ingredients with any suspected human health risks
- No processes that significantly or adversely alter the natural ingredients
- Ingredients that come from a purposeful, natural source (flora, fauna, mineral)
- Processes that are minimal and don't use synthetic/harsh chemicals
- Non-natural ingredients only when no viable natural alternative ingredient are available and only when there are absolutely no suspected potential human health risks

Essential Oil for St. Patrick's Day: Peppermint
Peppermint essential oil, also called balm mint or brandy mint, has a fresh, somewhat minty and strong smell. It is considered an adaptogenic oil, and although peppermint is not traditionally used in perfumery, the aroma is known to "give a lift" when inhaled.
The main constituent of peppermint oil produced in the United States is the alcohol, l-menthol (42.8%). Menthol is responsible for the cooling taste of peppermint, which is why peppermint is used extensively in commercial products, such as cough drops.
Before applying peppermint oil directly to skin, a skin patch test is recommended. You can also diffuse peppermint essential oil directly into the air for inhalation by using a terracotta light ring or a variety of diffusers.
Here's a recipe for a peppermint-based migraine rub (just in case!):
- Chamomile Anthemis nobilis oil: 5-drops
- Eucalyptus Eucalyptus globules oil: 5-drops
- Lemon Citrus limonum oil: 5-drops
- Peppermint Mentha piperita oil: 5-drops
- Base oil: 2-T
- Blend the oils and apply to shoulders, neck, and temples

Tell Your Congressman to Vote YES on HR 950
Rep. Filner states in his letter: "There should not be a distinction between those who attend a brick-and-mortar classroom versus those who study online and take their tests on a computer. Supporters of this bill are standing up for: disabled veterans, veteran families, rural veterans, and single-parent households who are getting an education and working to improve their lives. Join me in support of H.R. 950 and help restore equity by choosing to provide all our veterans with equal housing benefits while they participate in online higher education."
Your support for this bill would provide the same living allowance as veterans who choose to attend "brick-and-mortar", or more traditional, schools, and would show support for ALL veterans.

Wednesday's article in The Oregonian, "Oregon's suicide headache tree," reported that the camphor scent from the Oregon myrtle (also called California laurel) can cause severe headaches in some people and may contain important clues to "understanding mysterious cluster headaches."
Italian researches began to investigate the connection between Oregon myrtle and these headaches after learning of the case of a 69-year-old gardener who "was struck by a severe headache centered in his left eye" while pruning Oregon myrtle.
According to The Oregonian, Oregon myrtle was used by Native Americans to treat headaches: "Sufferers inhaled crushed leaves or applied a poultice to the forehead," a practice that bears comparison to homeopathy, which is based on "the principle of similars," according to the National Center for Complementary and Alternative Medicine website. The principle of similars, or "like cures like," states that "a disease can be cured by a substance that produces similar symptoms in healthy people."
Researcher Dr. Silvia Benemei of the University of Florence told The Oregonian, "'We are close to the identification of the mechanism.' [...] Finding the responsible chemicals could help explain what causes the disorder, and perhaps point the way to better treatments."

98% of ACHS Students Said They Would Recommend ACHS to a Friend
After several key developments in 2009, the American College of Healthcare Sciences sees the positive results in student satisfaction
American College of Healthcare Sciences (ACHS), one of the first accredited, online colleges to offer degrees, diplomas, and career-training certificates in complementary alternative medicine (CAM), also known as integrative medicine, celebrated its 20th year of operations in the U.S. in 2009. Building on its foundation of core CAM courses and programs, in 2009 ACHS also launched seven new certificate programs and six graduate certificates for specialized training in CAM in response to growing demand for CAM-trained healthcare professionals.
The January 2010 survey showed exceptional results from ACHS’s 2009 developments and a completion rate of 93% for the top 10 ACHS courses by enrollment. Of the more than 500 survey respondents, 95% said yes when asked, “Did you achieve, or will you have achieved upon completing your studies, the goals you had when you started the course or program?” When asked, “Would you recommend these studies to a friend?”, 98% said yes, and 98% also said yes when asked, “All things considered, are you satisfied with your studies with us?”
“Our surveys and results are a vital part of our outcome Assessment Program at ACHS,” said ACHS Senior Vice President Erika Yigzaw, who serves as the Institutional Improvement Officer. “We appreciate and value students’ feedback and comments, which we ‘feed back’ into our cycle of improvement. This cycle keeps us at the forefront of our industry.”
“We had our largest enrollment and number of courses starting January 2010,” said ACHS President Dorene Petersen. “That’s exciting! It feels wonderful to know our students are satisfied and happy with their studies, to know we’re meeting their needs, which is something we plan to do well into the future.”

FDA Commissioner Hamburg Posts Open Letter to Food Industry
Her "beef," NPR comments, is that "companies should stop misleading consumers by trumpeting a food as free of trans fat--implying that it's a healthy choice--when it also happens to be be high in unhealthy saturated fats." Nor should they make health claims about foods for kids younger than 2 or "representing that foods can cure or treat a disease."
NPR cites this example: "Nestle Drumstick Classic Vanilla Fudge [...] proclaims '0 g Trans Fat,' while the fine print shows 10 grams of saturated fat per serving, or 50 percent of the recommended daily amount."

Workplace Wellness Programs Help Employees Lose Weight, Lower Cholesterol and Blood Pressure
"At the start of the study," as reported by HealthDay, "33 percent of participants were overweight (body mass index, or BMI, of 25 to 29.9) and 30 percent were obese (BMI of 30 or more). The researchers found that obese participants lost the most weight -- 3 percent at 12 weeks and 0.9 percent at one year -- and were most likely to reduce their intake of dietary sugar. Overweight participants did almost as well, with an average weight loss of 2.7 percent at 12 weeks and 0.4 percent at one year."
All participants, though, showed improvement in levels of physical activity, lowered cholesterol and blood pressure, and reduced waistlines at the end of the year-long program.
The Massachusetts General Hospital researchers concluded that: "Voluntary wellness programs can successfully address weight loss and lifestyle behaviors for employees in all weight categories, but more work is needed to improve long-term changes."

Researchers Indentify 6 Essential Oils for Inflammation
According to the website The Medical News, these findings "provide more understanding of the health benefits of many botanical oils and provide a new avenue for anti-inflammatory drugs."
Of the commercial essential oils tested, the researchers were able to identify six (thyme, clove, rose, eucalyptus, fennel, and bergamot) that "reduced COX-2 expression in cells by at least 25%." Of these, thyme oil proved the most effective and reduced expression levels by about 75%.

NAHA Now Offers Mini Marketing Tips for Aromatherapy Professionals
In this first edition of NAHA Mini-Marketing Tips Kayla suggests "Determine Your Best Sellers-Cut the Dead Ends." She recommends focusing "on the top 20% of your products and services that bring in 80% of your sales. Phase out the rest unless they are support products for your top sales items. On a spreadsheet list every single product and service and put the total dollars sold next to each item. Sort them from highest to lowest and then determine which products make up the top 80% of total sales. You will find that they will be your top 20% of products or services. That means in almost every business, that 80% of your inventory is only doing 20% of your sales. But you are spending most of our money keeping those 80% of products or services available for that customer that uses them once a year."

Health Freedom News: Raw Milk Hearings
Historic Wisconsin Raw Milk Hearings Date Consolidation to March 10th, 10AM in Eau Claire, Wisconsin
The historic raw milk hearings for the raw milk bill in Wisconsin will be consolidated to one date–March 10, 2010 in Eau Claire, WI. There will be no public assembly hearing in Madison on March 16, 2010 for the raw milk bill because now a joint-hearing for both the assembly and senate committees will be on the same day of March 10. The members of both committees will be there. It will take place at the Chippewa Valley Technical College in Eau Claire, Wisconsin, 620 W. Clairemont Ave., Room 106/Auditorium 10:00 am.
RAW MILK & “FOOD FREEDOM RIGHTS” ADVOCATES FROM ALL OVER THE COUNTRY NEED TO ATTEND. We need 3,000 plus people to take part in this landmark event. If you plan on speaking, please bring a written statement to give to both committees, since there may not be not enough time for everyone to address the members. Get there early as parking will be an issue–carpool if possible.

Answers to the Myths of the Dangers of Soy
Recently there has been a lot of information being published purporting the evils of soy. I have been very concerned about this information and responded to a specific set of myths that were published on a popular website. The following is a summary of that research.
Myth #1―High levels of phytic acid in soy reduce the assimilation of calcium, magnesium, copper, iron, and zinc. Phytic acid is not neutralized by ordinary preparation methods such as soaking, sprouting and long, slow cooking. High phytate diets cause growth problems in children.
First off, all beans and grains have phytates. We understand this and are instructed to cook our beans and grains well and never eat raw. Second, assimilation is only potentially compromised in zinc and iron, as well as some calcium and magnesium. It has never been shown to interfere with copper absorption. However, though the possibility of this occurring is seen to interfere with the growth and mineral status of animals, it has never been seen in humans. In several studies done on humans there was no evidence of compromised absorption of any of these metals.
Sprouting has been shown to reduce phytate levels and fermentation is very helpful in this. Tempeh has ½-⅔ the phytate content of regular soybeans.[1] Also, cooking, germination, fermentation, soaking, and autolysis have been shown to decrease the inhibitory effect of phytic acid on mineral absorption.[2] Another important study noted that prebiotics and probiotics promote degradation of phytates in the gut.[3] Thus, it is very important to have very healthy gut flora to improve digestion of soy.
Myth #2―Trypsin inhibitors in soy interfere with protein digestion and may cause pancreatic disorders. In test animals soy containing trypsin inhibitors caused stunted growth.
Although studies have shown these adverse effects in rats, other studies showed no effect on mice or hamsters. Trypsin inhibitors are sensitive to heat. Therefore, most of their activity is lost when raw soybeans are exposed to heat.
As Liener explains, “Most commercially available soybean products intended for human consumption, such as tofu, soy milk, soy-based infant formula, soy protein isolates and concentrates, and textured meat analogs, have received sufficient heat treatment to cause inactivation of at least 80% of the trypsin inhibitor activity present in raw soybeans. This level of trypsin inhibitor destruction is well above the threshold level of 50-60% inactivation found to be necessary for eliminating significant growth inhibition and pancreatic hypertrophy."[4]
In addition, “All antinutritional factors such as phytic acid, tannin, trypsin inhibitor.. are decreased during soaking in 0.5% sodium bicarbonate.” In other words, soaking beans in a little baking soda will help reduce these things. “Human trypsin is more resistant to inhibition than is the trypsin of other mammalian species. The effect on human trypsin of soybean trypsin inhibition in soy protein does not appear to be a potential hazard to man.”
