Foods That Heal: #2: SWEET POTATOES!!!! (and RECIPES!)! Does Your Body Hurt? Do You Feel Sick? Want To Prevent Disease? Start Eating These Foods!!


Well folks its time for spotlighting another awesome anti-inflammatory, antioxidant food!  This time I thought I'd pick a starch that may surprise you!  SWEET POTATOES!!  

Yes, thats right folks, I'm talking about potatoes!  But sweet potatoes aren't really "potatoes" as we think of them!  While doing research for this post, I was surprised to discover that sweet potatoes themselves are actually not part of the "potato family"--they are a root vegetable in their own family completely separate from white potatoes & even yams!  So bring on these "potatoes!"   As I shared last week with KALE, in each post I'll share why each food rocks nutritionally and give you some recipe options to try to prepare it!  Once again, I'd love to hear any recipe ideas that you have to cook/prepare yummy meals with the featured "Food That Heals!"  Please share your ideas in the comments below!

And now:  back to the sweet potatoes!

You'll note that sweet potatoes showed up on all three of the anti-inflammatory/antioxidant lists I've shared on the blog.  Thats because they are full of powerful micronutrients that pack a major punch to fight & prevent pain, cancer & even stabilize blood glucose in diabetics!  Extra bonus--they taste delicious & have a relatively low glycemic index which makes them a perfect food to satisfy a sweet tooth!

I really love sweet potatoes--I have since I was young but when I became vegan and sugar-free I got a bit stumped on how to cook them!  I was so used to having them baked with butter and brown sugar or in a casserole with marshmellows!!  Luckily, the vegan blogger world stood ready to provide me with many tasty recipes to enjoy this nutritious & delicious treat!  I'll share some yummy recipes later in the post but first, why do sweet potatoes rock?  Remember, I'm a doctor but still engaged in my own nutrition education so I'll do the best I can explaining these nutrients!

Antioxidant Value

  • Vitamin A (1 cup provides 438% of the RDA!)--as I shared in Kale last week, Vitamin A is one impressive vitamin.  
  • Vitamin C--like Kale, according to "Prescription for Nutritional Healing" this vitamin is an "antioxidant that is required for at least three hundred metabolic functions in the body including tissue growth and repair..."
  • THE POWER OF PURPLE: 
    • In one study, the antioxidant activity in purple sweet potatoes was 3.2 times higher than that of a type of blueberry! This is due to the anthocyanin (discussed in anti-inflammatory value below) which was  found in one study to have the strongest antioxidizing power out of 150 flavonoids
    • I haven't been able to find any purple sweet potatoes at my local Whole Foods but I'm going to see if my little organic shop up the street will order me some from these folks that I found via Google!:-)
Anti-Inflammatory Value (some overlap with antioxidant)
  • Anthocyanin:  the pigment that makes sweet potatoes orange and sometimes, even purple!
    • a class of flavonoids.  As I mentioned last week, flavonoids are extremely beneficial, check out this paper by Dr. Joel Fuhrman.
    • Shown in studies to reduce the inflammatory agent  cyclooxygenase-2 (COX-2) {small informational note: COX-2 inhibitors--things that reduce COX-2--include the drug Celebrex!}
Other fantastic nutritional benefits include:
  • Potassium; manganese; Vitamins B6, B3 & B5; copper; tryptophan
  • FIBER:  nearly 4 grams per cup!
  • and MORE! 
What diseases are Sweet Potatoes thought to influence, prevent, reduce or improve:
***Caveat:  If you have kidney or gallbladder problems, check with your doctor before you eat a lot of sweet potatoes--they have oxalates in them which can crystallize.***

Recipes:  SO many great recipes!!  What are YOUR favs?

Ok thats all folks!  Enjoy!

Does Your Body Hurt? Do You Feel Sick? Want To Prevent Disease? Start Eating Foods That Heal: #1: KALE!!!! (and RECIPES!)

As you know I'm a huge fan of the concept of addressing chronic pain issues and other inflammatory diseases (Arthritis, Acute Muscle Strains, Fibromyalgia, Chronic Fatigue, Heart Disease, Diabetes and Cancer) with dietary change to improve healing and reduce pain!  I've written on my own journey with anti-inflammatory foods here and here, as well as shared with you some anti-inflammatory foods for kids AND a list of anti-oxidant foods to promote healthy skin!  


But lets face it, those lists can be really confusing!  Its just too much information sometimes.  So I've decided to start a post series focussing weekly on ONE powerful antioxidant, anti-inflammatory food that HEALS!  I'll share why each food rocks and give you some recipe options to try to prepare it!  Even better, I'll get feedback (hopefully) in the comments from all of you with other tasty ideas for preparing the "Food That Heals!"


This week the magic food is:  KALE!!!


Its one of my favorites--pretty much since I went to the farmers market last summer and kale was on sale for 1 pound for $1.  I had no idea how much kale weighed, so I told the man:  "I'll have 5 lbs!"  Oh boy, thats a lot of kale!!! Wowsers.  So I started cooking it. And liking it!  Then in Dr. Esselstyn's book Prevent & Reverse Heart Disease, Ann Esselstyn also extolled the virtues of kale.  And so on and so forth.  Dr. Joel Fuhrman's nutrition density scale ranks it #1 out of 20,000 foods according to PeerTrainer.


Kale makes it on every anti-inflammatory, antioxidant list because it is chock full of nutrients.  Lets review what those are!  Remember, I'm not a nutritionist.  I'm a doctor learning how food interacts with the body systems I've studied in minute detail! 


A great article in the Huffington post on kale is here.


Kale's Antioxidant value centers on:
Anti-inflammatory power (many antioxidants also double as anti-inflammatory agents):
Other fantastic nutritional benefits include:
  • Magnesium, Vitamin B6 (pyridoxine), Calcium, copper, potassium, iron, manganese and phosphorus
  • FIBER:  5 grams per cup!
  • and MORE!  Check out this link for more details!
What diseases is Kale thought to prevent, reduce or improve:
  • Reduces Pain significantly if eaten on a regular basis like all cruciferous vegetables.  Check out Dr. Neal Barnard's book: "Foods That Fight Pain"
  • Helps lower cholesterol (due to the fiber's effect on bile acids--this effect is maximized when kale is cooked!)
  • Helps reduce heart disease (by absorbing fat through the bile acid binding mechanism derived from fiber)
  • Helps prevent osteoporosis (through Vitamin K's role in creating osteocalcin, the protein in bone tissue on which calcium crystalizes"
  • Helps prevent cancer (excellent source of glucosinlate phytonutrients)
IMPORTANT CAVEAT:  Buy Organic Kale whenever possible!!  It is part of the "Dirty Dozen" list of high pesticide foods!!

Here is a sampling of recipes from some of my favorite bloggers and authors:

Ok!  What is YOUR favorite Kale recipe??!!

Any requests for foods for next time?:-)

Best of the Blogosphere From the Last Week!! Tons of PARTY RECIPES for The Super Bowl Party, Diabetes & Vitamin D, Small Town Living & MORE!

Well it looks like everyone in the blogosphere is gearing up for the big day:  The Super Bowl!!  We're off to Florida for vacation next week (thank goodness!!!) and Sunday is my husband's birthday so the Super Bowl action has been a bit off my radar!  Still, any party is a challenge food-wise if you are a compulsive overeater OR someone with food restrictions (i.e. vegan, gluten, sugar, etc).  So thank you thank you thank you fellow bloggers for giving us all some fantastic healthy ideas to make a party weekend fun and delicious!!  Below, I have a list of some great Super Bowl or snack related blog posts, but first, a caveat:


If you are worried about maintaining your healthy eating habits during a social event, I encourage you to check out my blog post Holiday Survival Tips.  Here are the party tips in a nutshell (I explain the tips in the post):

1) Use the "One Plate Method" of eating at all events involving food
2) Call ahead to events so you can plan your food strategy & if appropriate, offer to bring a dish
3) Talk about "allergies"
4) Make sure to have a lot of yummy meals on hand at home (your FAVORITES) throughout this season so you never feel deprived.
5)  Eat at home before food events and eat the foods from Tip #4!
6) Become willing to believe that there is NO SUCH THING as "one bite" or "just a little taste" or "just this one time" or "I don't want to offend anyone by not eating this lovely meal."
7)  Use your resources
8)  Remember the point of a party
9)  Leave
10) If you slip once, get right back up and march on as if it didn't happen!
11) Make new traditions that don't involve food
12) Be realistic

OK, moving on.....

The Best of the Vegan Super Bowl Party Blogosphere:
and now non-Super Bowl, my favorite blog posts for the week:
  • Awesome post from The Healthy Librarian on Type 2 Diabetes:  How Exercise Intensity, Meat & Fat Consumption, Vitamin D, Body Weight, & Muscles All Affect Type-2 Diabetes. Vitamin D is my research area--I just completed a study Vitamin D's effect on falls--many people are not aware how important this Vitamin is for a number of body functions.  I feel the current RDA for Vitamin D is incorrectly low--for folks over the age of 65, 2000IU daily is a much better dose (if you don't have hypercalcemia or renal disease).  That said, I do not believe loading folks with high dose Vitamin D (50,000 units etc) is safe with regards to bone metabolism!  And on a funnier note, OH MY GOSH I SOOOOO want to put this cartoon that she shared in the story on a t-shirt and wear it every day!  
  • Ok this is technically from last week but its too good to pass up mentioning!  This blog post on the Nutrition Facts blog is a fantastic way to learn more about which foods are dense in anti-oxidants:  Acai to Zucchini: antioxidant food rankings
  • If you live in a small town than definitely don't pass up this Engine 2 Diet blog "The Daily Beet" post:  5 Tips for Small Town Living.  I did part of my medical training in a very rural area and we are considering returning to a rural area to practice in the next few years so I found this post to be an awesome guide!

Well thats a sample of MY favorites!  What were YOUR favorite posts this week?!

Healing Your Skin with Food!! Part 2 on "The Clear Skin Diet"

Yay!  Spots Gone!:-)
Today I want to follow up on my previous post "Ok Lets Talk Skin!  New Book to Recommend:  The Clear Skin Diet!"  Since that post two weeks ago I have continued to follow Drs Logan and Treloar's nutritional program to feed my skin the right nutrients it needs to heal!!  I'm delighted to report that after applying my dermatologist recommended products, completely eliminating soy from my diet since mid-December and strictly adhering to my omega-3 fatty acid supplement regimen, the "spots" are gone!! I actually was complimented twice this week on my skin sans makeup!  Whoohooo!  

For my omega-3's, I'm taking a multi-pronged approach.  It turns out that there is soy in a lot of those algae-based vegan omega-3 supplements!  So they were out for me.  I started doing more research and now I'm targeting components of omega-3's:  both DHA and EPA.   After reading several studies on brain function associated with DHA and the difficulty vegans sometimes have in converting EPA into DHA, I decided to splurge and get Dr. Fuhrman's liquid pure DHA.  Its expensive!  I put a few drops into my food or drink each day and consume that.  I also have been eating a lot of chia seed (which, like flax I think I'm now having a reaction too--argh!) so I'm heading back to my good old fish oil supplements for necessary EPA.  If what I just wrote sounds like a foreign language (and it would have been to me a few weeks ago!) then check out the following:


2) a fantastic series on fats by the Vegan Epicurean:

The additional omega-3's have been amazing for all of my skin in general--the winter dryness has decreased significantly.  Of course I'm still using my dermatologists regimen of various cleaners and lotions (I think this regimen is brilliant so check out the comments on the previous skin post for details on that regimen).  One caveat, I have noticed though that my skin is very very sensitive to what I put in my body.  A little grease--boom, new spots.  Too much of one thing (excessive chia seed--and yes, I know this is an EFA and it doesn't make sense but its the truth!)--boom, new spots.  And so I've continued to read The Clear Skin Diet by Dr. Alan Logan (ND) and Dr. Valori Treloar (MD) closely and have learned SO much about nutrition in general and what is best nutrient-wise for skin care!  

Last post I shared Drs Logan and Treloar's assessment of what the native Japanese & other ethnic groups with gorgeous clear skin eat (and we should too!).  

From p.163 of The Clear Skin Diet by Dr. Alan Logan (ND) and Dr. Valori Treloar (MD), ethnic groups with beautiful skin eat:

1. Less processed foods (my side note: this can be a vegan problem too--a lot of the "fake meats" are very processed)
2.  More colorful antioxidants
3.  Greater intake of omega-3 fatty acids
4. Fewer foods capable of spiking blood sugar
5. More fiber 

I am now hitting all five of the recs instead of just four and wanted to also share with you Drs Logan and Treloar's list of the highest antioxidant-rich foods that feed your skin and the doctors' advice on the specific types of food to embrace to have clear, healthy skin!   

Now, as you long-term readers know, I've posted on anti-inflammatory and antioxidant-rich foods in the past regarding my approach to pain management, but I wanted to share Drs Logan and Treloar's list in particular as it does a nice job of detailing out in a more extensive list all the specific fruits and vegetables that are the most antioxidant-rice foods!!

Basil
Beans (red, pinto, black & navy)

Black-eyed peas
Black pepper
Blackberry
Blueberry

Ok Lets Talk Skin! New Book to Recommend: The Clear Skin Diet!

Before

Ok so I've been having some issues with my skin that began a few months into my change to going strictly vegan! This perplexed me because I heard from so many others that the vegan thing has been wonderful for skin!  But since early November, my previously pretty perfect skin (and yes, this is my one vanity--first of all its genetic so I didn't do anything special and second of all it was the only thing I could really feel pretty about when I was obese so indulge me!!) broke out into spots that my new dermatologist calls "folliculitis" or irritation of the hair follicles.  It looks like teenage acne but it isn't.  


After (this past month)!
Of course it has caused me significant distress to look in the mirror every day (I think I was driving my husband crazy as I pointed out every new spot that cropped up!  His favorite phrase was: "welcome to my teenage years honey.")


Anyways, so when this all happened I started trying to figure out where I went wrong.  Nothing major in my life had changed--I had the usual stressors with work and family members being ill but this was normal for me.  So I started looking at what I ate.  The only new food that I can ascertain that I added in a major way in early November was that we went from eating soy maybe once every few months to soy everyday.  And before you point out the obvious--yes I know that I also eliminated animal products, but dairy and other meats are known to be a huge pro-inflammatory agent that cause skin issues so I really don't think the animal-free diet was the cause.  With this in mind, as a first step I eliminated soy. 


I have to be honest and share that this soy elimination has really, really upset me.  My dietary program is already quite restrictive in many ways--no sugar, no gluten, vegan....so to add soy to it too!  Argh!!  But I'm attempting to embrace a new cooking opportunity (trying to stay positive here!), so I'm searching out non-soy recipes.  So let me know if you all have any low-fat/no-fat non-soy, gluten-free, sugar-free recipes please?  Much appreciated :-)


Anyways, back to the skin problem.  With the elimination of soy I did notice that my skin started to improve.  But it was still not back to normal. So I bit the bullet and went to my first dermatology appointment.  And there, I really hit the jackpot.  I expected a very traditional doc as I knew he had a military background and was well over the age of 70 but much to my surprise, within the first two minutes of the visit he started talking nutrition!!  And then he actually complimented me on my dietary choices.  Whaaaat?  I know, you are all shocked here but he actually liked the vegan thing and the gluten-free thing and the sugar-free thing.  


Full disclosure, he wasn't 100% on board with my soy theory--mostly he thought it was likely not a true allergen but more like a "trigger" for beginning eczema (which is what he described my spots as!). And of course now my skin bumps were infected (helllo work in health care, land of disease!) and so I needed oral antibiotics on top of everything else!  He also gave me an excellent skin product regimen which I'm happy to share with all of you if you would like.  I say excellent because its been less than a week since the appointment and my skin is nearly completely clear (of course I also haven't had any soy for 2 1/2 weeks so I can't give the products all the credit but my skin certainly feels really nice!):-) 
Today
Soy Free, Omega-3 rich,
Dermatology Products & Antibiotics


Back to what he said about nutrition.  You all know I'm a fan of food-based treatment so isolating a soy allergy or "trigger" was not enough in my book.  I started wondering why I, with my anti-inflammatory diet, had developed a completely inflammatory disease (eczema)!  I have a strong family history of eczema so this diagnosis actually wasn't all this surprising but hearing that it was a potential diagnosis brought me back to reflect on whether I had made the right anti-inflammatory food choices.  Remember my list in my post  HERE? 


I found the answer in a book my dermatologist recommended:  The Clear Skin Diet by Dr. Alan Logan (ND) and Dr. Valori Treloar (MD).  I'm not finished reading it yet but I can tell you that from what I've read so far it is AMAZING!!!  It definitively demonstrates that diet DOES have a major impact on skin AND also reinforces my assertion that the reason most physicians don't prescribe nutritional treatments is that we are generally not educated in nutrition at all & therefore are very skeptical of data supportive of nutritive cures!  Don't get me started on the need to change medical education or else this post will be ridiculously long!  Suffice to say (and I'll write more about this in a second post because this one is getting too long), Drs Logan and Treloar give some fantastic advice.  


From what I can tell so far, my main issue appears to be a omega-3 deficiency.  This makes sense to me because the only other major change in my diet except for the soy was dropping my fish oil daily in favor of flaxseed meal!  Despite my own advice, I obviously wasn't loving the flaxseed meal (I ate it VERY inconsistently) so I have started to search out other plant-based omega-3 sources (in the meantime I'm back to fish oil daily).  


I do still strongly believe soy is at the root of this as well because it IS considered an inflammatory food for some, so I'm going to continue to eliminate it for another month & then start a few gentle food challenges to see if it really does have an impact. But for the omega-3 issue I'm going to start taking The Healthy Librarian's advice and try a seaweed-based omega-3 supplement with DHA (good for the brain).  In the meantime, I'm going to keep reading this book!  


I'll end with Drs Logan and Treloar's assessment of what the native Japanese & other ethnic groups with gorgeous clear skin eat (and we should too!).  From p.163 of , ethinic groups with beautiful skin eat:
1. Less processed foods (my side note: this can be a vegan problem too--a lot of the "fake meats" are very processed)
2.  More colorful antioxidants
3.  Greater intake of omega-3 fatty acids
4. Fewer foods capable of spiking blood sugar
5. More fiber 


Sounds pretty darn good to me!  Tune in to my next post on skin to get Drs Logan and Treloar's list of the highest antioxidant-rich foods that feed your skin and the doctors' advice on the specific types of food to embrace to have clear, healthy skin!
