In case you haven’t heard…there’s a revolution going on!  It starts in the ground, is grown to feed the earth and to nourish its inhabitants. Food.  A precious yet vital source and the key to sustainable health.  For some, access to food is more difficult than others.  Here in the Napa Valley, we live in a climate that is temperate and suitable for planting a variety of crops.  Sure, we’re known for our grapes, but there are so many possibilities for additional food production that we are just beginning to uncover…

This week I am honored to be part of The Whole Gang’s Food Revolution where 30 fellow bloggers have come together to continue the momentum Jamie Oliver has created, ‘saving our health by changing the way we eat.’  And as a matter of fact, the Napa community has answered that call by launching its first annual “Napa Local Food Forum,” which was held April 28th at the Expo Fairgrounds.

This event was the brainchild of a diverse group of people led by our Agricultural Commissioner with a common vision: to ensure our local food system is socially equitable, environmentally sensitive and economically stable, by producing more food locally and providing access to all.  That means from individuals like you and me, to institutions like our hospitals and schools.

Getting there is no small task and now is when the real work begins.  Through a rich network of panelists, the discussions were loaded and lively.  The range of topics included:

*Enhancing Agricultural Opportunities in Napa County
*Small Scale Food Production
*Sourcing Local and Sustainable Food
*Distributing Food Locally
*Matching Local Foods to Institutions

There was an informative presentation by our County Public Health Officer who laid the groundwork on our current ‘un’healthy state of the union ; a local, seasonal lunch provided by many generous donors throughout the Bay Area, followed by a public town-hall platform where many could express their interests on how to move this agenda forward.

You might be asking how this applies to you…or better yet, how can you get involved?  The challenge is open to anyone who wants to see healthier food at home, in your community.  It can be as easy as planting a row of herbs, to an entire acre of tomatoes and beans.  For example, I have just begun the process of replacing our lawn with planter boxes of leafy greens and root vegetables to accompany my oregano and parsley.

Here are additional ways to bring more locally grown food into your lives:

Plant an herb garden. This doesn’t require much time or space. You can use a box or several pots. And you can buy the starts at nurseries or farmers’ markets.

Buy produce in season – you’ll get maximum flavor, nutrients, and bang for your buck.

Support your local farmers – right now is the beginning of peak season at the farmers’ markets.  Or join a CSA- community supported agriculture. If you don’t have the space or the time to grow your own produce, at least you’re supporting agricultural diversity and keeping transport to a minimum.

For those with land who want someone else to manage it, there a wonderful resource called Farmlink that will connect landowners with aspiring farmers.

Become part of a community garden, or start one of your own.  There are many tips on how to go about it.

If you do have the inkling to reconfigure your personal landscape - check out this video by a family in Pasadena who has turned cement into a green cornucopia.  They now produce much of their own food on less than 1/10th of an acre!

Let your voices be heard in schools.  I think we all know how processed foods have infiltrated kids’ lunches…but it takes a village to demand fresh choices and affect change.  Just look at all the comments that Jamie Oliver receives, and in return he offers recipes and other resources for healthy lunches.

Curried Cauliflower – Serves 4

Cauliflower is in ‘bloom’ at the farmers markets and now it comes in glorious colors.  They all have the same flavor and will take on whatever spices you add in cooking.  I love curry for its exotic taste and its anti-inflammatory properties.

2 tablespoons olive oil
1/2 cup diced onion
2 cloves garlic, minced
1 teaspoon finely chopped fresh ginger
1 tablespoon curry powder
1 teaspoon ground cumin
4 cups cauliflower florets, washed and dried
2 tablespoons fresh lime juice
1/2 cup organic coconut milk
1/4 cup vegetable broth or water
Sea salt and fresh ground pepper

1. In a large skillet over medium heat, add olive oil and sauté onion, garlic, and ginger for about 3 minutes. Add curry powder, cumin and sauté for an additional 3 minutes, until fragrant.
2. Add cauliflower and lime juice and stir-fry on medium-high heat for about 5 minutes. Reduce heat, add coconut milk and broth or water, cover partially, and simmer on low heat for about 5-10 more minutes, until cauliflower is crisp-tender. Add salt and pepper to taste, if desired.

This recipe was inspired by nutritionist James Rouse.

As we prepare our Thanksgiving menus, many fresh herbs come unto play which not only taste good, but are good for you.  From appetizers to dessert, herbs like sage and thyme sprout from the garden into the kitchen.  The wafts of their fragrance bring back fond childhood memories which come to life again and help with everything from digestion to stress.

Herbs and spices can be used much more liberally than salt and add much more personality to every dish.

Cinnamon: used in baking this is a warming herb which helps regulate blood sugar – particularly important during the holidays. It stimulates circulation in the body, reduces LDL cholesterol and gas.  The volatile oils in cinnamon (bark) have been shown to kill bacteria (antiseptic.)

Cloves: used in baking and beverages, this sweet spice helps prevent the absorption of environmental toxins.  It aids in the treatment of joint inflammation and is often used as an anesthetic to reduce pain in the mouth, esp. gums.  Also noted  for helping pets prevent tapeworm.

Coriander (cilantro): pairs well with root vegetables like beets and potatoes. Coriander is the seed from cilantro which is carminative (anti-gas), anti-inflammatory, and anti-microbial. Coriander also helps with the digestion of fats and reduces LDL cholesterol and stress.

Cumin: used in soups, stews, or as a rub on turkey, cumin acts as a digestive enzyme which helps support nutrient assimilation.  It has potent free-radical scavenging abilities, and enhances the detoxification of the liver – an organ which can be burdened this time of year.

Parsley: used in soups, stuffing, and a multitude of holiday dishes, parsley is a nutritional powerhouse.  Its super high in vitamin C, which helps build the immune system (also key this time of year) and…its a great source of calcium, iron and potassium.  It is also good for the prevention of cancer.

Rosemary: a piney herb which pairs well with roasted meats, vegetables and soups.  Known to help reduce inflammation, rosemary also stimulates the immune system,, increases circulation and improves digestion.  Another bonus is that it increases blood flow to the brain, thereby helping our memory (pass the rosemary, please!)

Sage: known for its aromatic and tasty influence on stuffing, sage is also a great addition to chicken and pork.  It acts as an antiseptic for sore throats and is also another digestive aid.

Thyme: great with poultry and rice dishes, thyme is a member of the mint family. Its high in antioxidants and is antibacterial and anti-fungal. It also has a calming influence on those with ADD.

>>Notes: As part of a “Progressive Holiday Dinner” beginning Monday, Nov. 16, I will be posting a few recipes this week along with six other food bloggers in advance of Thanksgiving.  There will be lots of exciting entries – details Tuesday!

A lot can happen from the time produce is picked off the vine or pulled from the earth. Some fruits and veggies go to a packing house; others are cooled and transported an average of 1200 miles before reaching the consumer.  Freshness equals nutrients, not to mention color and flavor.  But we certainly can’t eat all of our purchases in one day.  And while I’m trying to keep up with summer’s bounty by roasting tomatoes and making pesto, if I have to store my fresh-picked produce for a few days, I’ll want to keep it as close to its most natural state as possible.

Since I know you are all shopping at your local farmers’ markets, here are some hints on how to preserve the freshness and nutritional values of your perishable produce:

Store at room temperature
apples               lemons                 pineapple
bananas            limes                    pomegranates
grapefruit         mangoes              papayas
watermelon      persimmons        zucchini
garlic                dry onions            potatoes (put in paper bag and keep in drawer)
tomatoes          eggplant               peppers

Ripen on counter first, then refrigerate
avocados       nectarines         pears
kiwi               peaches             plums

Refrigerate
blueberries       cherries           strawberries (put in Tupperware with paper towel)
apricots            grapes             figs
raspberries       blackberries    greens like kale, spinach, Swiss chard
green beans     herbs               Brussels sprouts
carrots             cabbage           basil (put in vase with water, cover with plastic bag)
radishes           corn in husk    lettuces (wash first, then store in plastic bag with holes)
cauliflower      celery              leeks
beets                broccoli           mushrooms (put in paper bag in produce drawer)

In order to maximize the nutrients you receive, it is best to consume your fresh produce within two days of purchase, but these tips can help extend their life span. General rule of thumb is to wash all produce – even citrus – just before eating, with exceptions above.

I figured if I’m starting a feature called “Savvy Substitutions” and it focuses heavily on baked goods, it might be advisable to explain different types of flour and their ratios in baking compared to the ‘other white stuff.’  Of course you know it begins with whole-grains, and organic whenever possible.  Wheat is one of the most pesticide laden crops in America, so it truly pays to buy the purest product available.  This way you can go right to your pantry when a recipe calls for spelt (a cousin of wheat) or another alternative and know how it might affect the taste and texture of your creation.

What whole grain flours offer that white flour omits are multiple nutrients.  White flour has been stripped of vitamins and fiber.  In the refining process, the bran and germ have been removed and only the starch – or simple carbohydrate – remains.  This is what spikes the blood sugar and depletes other vital nutrients in our body as well.  Specifically, B vitamins, which are essential for digestion and keeping stress at bay.  When you eat white flour or sugar, the body uses up the B vitamins merely in trying to assimilate them into our system.

So let’s take a look at our whole-grain friends, which are also high in antioxidants and vitamin E.  They help prevent obesity, diabetes, and heart disease…all on the rise in the U.S.

> I will also note if the grain is gluten-free (GF.)

Almond: there’s almond meal and there’s blanched almond flour. They are very different, according to Elana’s Pantry.  I bought some almond flour (hard to find) and used it in a Nutty Bread recipe from the same site.  Fabulous.  GF

Barley: user friendly, slightly heavy.  Can be used in cakes, cookies and pie crusts.

Brown rice: great for breads, muffins and sometimes cookies, as it can be somewhat grainy.  One of the most digestible grains and high in nutrient value.  GF

Buckwheat: a cousin of rhubarb and no relation to wheat  Acts like gluten with its binding characteristics but can be tolerated by gluten sensitive people.  Somewhat nutty flavor and a heavier texture.  Best in pancakes. GF

Oat: mild. slightly sweet and moist.  Esp. good combined with brown rice or barley flours. OK for most gluten sensitive people.

Spelt: the most versatile and white flour-like of all, next to whole wheat, yet easier to digest.  Great in most desserts, cookies, breads, muffins and the one I use most often when substituting for white flour.  High in protein, amino acids and minerals.  Hartke’s shares details about it, and Heidi offers some great recipes.

Teff: an ancient grain, dense and moist; especially good with chocolate, as in brownies. High in iron and calcium.  GF

>> A few more notes:

• Many of the whole-grain flours have different gluten levels (elasticity), if any at all.  Therefore, they can be tricky in baking.  You can start out by mixing 25%  in with your white flour to experience the taste and texture of each type. Eventually, try to use whole-grains either by themselves or one for one to maximize the nutritive values in the recipes.  Gluten-free flours have different requirements.
• Increase baking powder by 1/4 to 1/2 teaspoon per cup of flour.
• Whole-grain flours are more perishable, so for optimum storage and freshness, keep them in the refrigerator or freezer even if package is unopened.  I store mine in different bags and jars – just make sure to label and date the container, and try to use within a few months.
• Cooking times will vary based on ‘new’ ingredients.  Keep a thermometer handy.
• There are other additives like xanthan gum, guar gum, tapioca starch and potato starch which act as leaveners and binding agents when gluten is absent.  This is where it becomes a bit complicated, so start slowly and practice patience.

Have you tried other flours?  What have your experiences been?  Are there any favorite recipes you’d like to share?

Happy Earth Day!  What are you doing for this holiday?  While that might not mean ‘day off work…’ it IS a reason to celebrate, for all that we do, eat, and live by is a result of how we nurture it.  Since my mission is all about ‘promoting a healthy appetite for a thriving planet,’ I thought it was only fitting that I devote this post to food as it relates to the earth (and, as you know, they are intricately connected.)

We had a most fascinating discussion in class the other day.  It was about seasonal eating by following the vegetable plant. Take the individual components of the plant and note how they grow at the same time.  For example, starting with the roots (carrots, parsnips, beets, onions, turnips) – these all grow in winter.  Followed by stems (celery, fennel, rhubarb) and flowers (asparagus, broccoli, cauliflower) which peak in spring, to fruits (tomatoes, avocado, eggplant, peppers) and seeds (peas, corn, green beans) which begin the cycle all over again.

When we eat our foods in peak season, we are not only benefiting from their freshness and flavor, but also the maximum nutrients they offer us.  And with regards to planet Earth, if we grow or buy our produce locally, we are keeping fossil fuels to a minimum and ensuring that diversity thrives in agriculture (like all those veggies listed above.)

Bringing it back to the kitchen, I am sharing one of my favorite spring recipes to celebrate the bounty which Earth so beautifully provides us.

Strawberry-Rhubarb Crisp ~ Serves 8

Notes: In the photo, I used 1/2 cup crumbled gluten free ginger snaps instead of the oats.  The entire recipe is gluten free but as noted, you can use any whole grain flour instead.

Topping
1/2 C brown rice flour (any whole grain flour is fine)
1/4 C Sucanat*
1/2 C rolled oats
1/2 tsp. ground cinnamon
1/4 tsp.  ground ginger
1/4 tsp. ground allspice
1/2 C finely chopped walnuts or pecans
1 TB freshly orange zest
4 tablespoons unsalted butter, melted
¼ C fresh squeezed orange juice

Filling
1 pound rhubarb, cut into 1/2-inch pieces (about 4 cups)
1 C fresh organic strawberries, sliced
3 TB agave nectar or honey
2 tsp. brown rice flour
1/2 tsp. vanilla extract

1. Mix all topping ingredients – except orange juice – in a medium bowl or food processor until mixture begins to clump together.  Add juice as needed.
2. Preheat oven to 400°. Combine all filling ingredients in a large bowl and toss well to coat. Transfer to an 8×8-inch glass or ceramic baking dish.
3. Crumble topping evenly over fruit. Bake until fruit is tender when pierced with a fork and topping is crisp, 30–35 minutes. At 20 minutes, cover with foil if necessary to keep topping from overbrowning. Cool 20 minutes before serving.

*Sucanat, or dehydrated cane juice, contains the vitamins and minerals needed for the body to digest sugar.  It is darker in color because it has not been denatured.  You can find it under the brand names of Sucanat and Rapunzel’s Rapadura. It can be substituted one for one with white sugar. Refined (granulated, white) sugar has been stripped of alkaline minerals and can have a jolting impact on the stomach and pancreas.

So now it appears I’m on a coconut kick!  Once I toasted the flakes for the carrot soup, I decided to try a sweet creation…and with Easter just around the corner…

I was inspired by a vanilla cupcake recipe in the book, “Cooking with Coconut Flour,” by Bruce Fife. I’m always playing with alternative flours and recently discovered an organic coconut flour from Tropical Traditions. Ever heard of it? It’s a gluten free option that is high in fiber and protein. And according to the book, it has many more health benefits.  It is said to regulate blood sugar, protect against diabetes, improve digestion, and aid in weight loss.  “CwCF” contains recipes for primarily baked goods – from quick breads and cookies, to muffins and pie crusts.  It even offers ideas for savory dishes substituting this nutritious flour for all purpose flour, in foods like tamale pie and veggie meat loaf.

Because coconut flour does not contain gluten, eggs are used to a larger degree than in most cake mixes.  Gluten is a protein which has an elastic character and traps air bubbles.  Without it, baked goods become more dense – as seen in this photo.  I had several friends try a batch, and most of them favored the rich quality this recipe contained.  But then I got to wondering – what differentiates a cupcake from a muffin other than the frosting?  Turns out there is quite a conversation about it on other sites.

Wanting to put the full coconut flavor to my cupcake mix, I used coconut oil instead of butter and added coconut flakes to the batter. Then I made a creamy frosting from cashews, and topped the muffins cupcakes with toasted coconut. I also think this would make a wonderful cake, so if you feel the urge, pull out your bundt pan and double the recipe.

Coconut Cupcakes – Makes 8

Coconut flour cannot be substituted 1 for 1 in normal recipes.  Eggs are the binding source here, which might also explain the density.  For the frosting, you could also make one with coconut milk and powdered sugar for another shot of coconut.  Either way, these cupcakes are moist and delicious.

6 TB organic coconut oil, melted
6 pastured eggs
1/2 C agave nectar
1/3 tsp. salt
1 tsp. vanilla
1/2 C sifted coconut flour (I just use a strainer)
1/2 tsp. baking powder
1 TB unsweetened coconut flakes

Blend together oil, eggs, agave, salt and vanilla.  Combine coconut flour and flakes with baking powder and whisk into batter until there are no lumps (but be careful not to overmix.) Pour batter into greased muffin cups and bake at 400 degrees for about 15 minutes.  Cool before frosting.

Cashew Frosting - Makes 1.5 cups
This is a favorite recipe from Cafe Gratitude called “I Am Smooth.” If there’s any extra, add it to your green smoothie

1.5 cups soaked cashews (soak in cold water overnight)
1 TB, plus 2 tsp. lemon juice
3 TB, plus 1 tsp. agave nectar
1/2 C water
2 TB unsweetened coconut flakes, toasted

Rinse soaked cashews and add them with all ingredients to blender.  Begin to pulse slowly, then turn up speed.  You may have to scrape the bottom to keep it from clumping. Add more water if needed. Frost cupcakes and top with coconut flakes.

It’s nice to hear positive news every now and then, especially when it comes to money and our health.  Yesterday the NY Times published an article about our first lady, Michelle Obama, committing to eating healthy and spreading the good word. How encouraging that someone with such visibility and influence is taking a leading role by influencing everyone from our children to those who need it most.

The day before, our friend in real food, Michael Pollan, solicited readers to share thoughts on ‘smart eating’ and has received over 1,900 responses to date!  Comments range from “Cook every meal at home using real ingredients and you will be eating healthy,” (which I will expand upon in ‘how to save food $ at home’); “Food rule : enough is too much,” to “Don’t eat anything you can buy at a gas station.”

There is much to be said for what our grandparents taught us about taking time to eat whole foods.  I would add purchasing foods which come from organic, sustainable sources.  For details on the most crucial foods to buy organic, the Environmental Working Group offers a wallet size card of the so-called “Dirty Dozen”  and the “Clean 15.” As for me, I choose to opt out of any chemicals – no matter how much residue is detected. It’s also a commitment  to preserve the integrity of our environment, and the small farms that depend on it.

Another article appeared in the SF Chronicle this weekend on what I call Edible Home Remedies.  As a victim of frequent migraines, I have also tried adding two drops of ghee in each nostril, which is an Ayurvedic healing method.  (Can’t say it has done much for me yet – other than prompt me to butter my bread;-) Gargling with salt water is good for sore throats and toothaches; and eating pineapple helps with digestion.

What are your thoughts on eating smart?  Have any edible remedies you’d like to share?

Valentine’s Day is fast approaching…and I heart chocolate.  (I used to be a vanilla girl – now I’m both (see photo.)  In case you needed justification, chocolate actually has heart healthy benefits.   According to Body and Soul Magazine, dark chocolate (70% or higher) is said to tame high blood pressure and fights inflammation.  In a recent study from the Journal of Nutrition, people who ate modest amounts of dark chocolate had 17% lower blood levels of C-creative protein, which increases the risk of heart disease.  Now here comes the Mom in me…a little dab’ll do ya.  A small square of dark chocolate two to three times a week delivers potent heart healthy antioxidants.  And that’s about the amount we use in the following recipe.

Ingredient notes:

I always buy organic whenever possible, as well as fair trade when it comes to chocolate.

If desired, you can substitute carob for chocolate, which is rich in dietary fiber (26%) and polyphenols, good for healthy aging.

This easy cake is almost like a souffle, it is so light and fluffy. The polenta gives it a nice texture, and also makes it gluten-free.  I topped mine with my favorite ice cream:  organic mint chip by Humboldt Creamery.

Chocolate Polenta Cake

Serves 6-8

1 cup plus 2 TB organic milk
2 1/2 TB polenta
2/3 C (4 oz.) chopped organic dark chocolate (can also use chips)
2-3 TB agave nectar
2 whole eggs
4 egg whites
1 TB applesauce
1/2 tsp. baking powder
1 tsp. pure vanilla extract
1/4 tsp. sea salt

Heat oven to 350.  In medium saucepan over high heat, bring milk to boil, then whisk in polenta.  Reduce heat and cook 3-5 minutes, stirring constantly until thick.  Let cool slightly.
In another pan, slowly melt chocolate over very low heat. Blend in polenta mixture.
In a bowl set over simmering water (or double boiler) whisk together eggs, whites, and agave until warm.  Remove from heat and beat on high until it reaches 6-8 times original volume.  Add applesauce, salt and vanilla to chocolate mixture and blend well.  Fold in a fifth of egg mixture. Sprinkle baking powder into mixture and gently combine.  Slowly fold in remaining egg mixture one third at a time.  Pour batter into buttered 8-inch square baking dish.  Bake 25-30 minutes.  Let cool on wire rack.

This recipe is featured in The Nourishing Gourmet’s Chocolate Carnival.

In his first major interview since becoming U.S. Energy Secretary, Steven Chu did not ‘mince’ words with regards to the status of California’s agriculture.  The state is in its third year of drought, which is compounded by higher global temperatures preventing snow accumulation.  That runoff is what feeds our rivers and reservoirs, ultimately leaving our farms high and dry.  With California as a producer of half of all U.S. vegetables, the future of our food chain could be severely impacted by the end of this century. How can we help?

No matter where you live, begin reducing water consumption at home as soon as possible.  Even with drastic rainfall in the next few months, there will undoubtedly be water rationing as we head towards summer.  Take shorter showers, flush the toilet less often, turn off the faucet when brushing teeth. And the lawn can take a break in winter (or better yet, go ‘forever green’ with artificial turf. NO water needed and it looks SO real!)

Learn about the crisis with another influence on agriculture: the honey bee. As if  the drought isn’t bad enough, there has been a significant drop in their population with colony collapse disorder.  These little guys are responsible for pollination of a majority of our crops and their demise is seriously devastating.

Support local farms.  Know the source of your food and the methods of farming.  Small farms are in dire need of support to ensure food safety and sustainability.  Remember, we are what we eat – and drink – which may be one in the same before long.

Now if you’re thinking that Atlantic salmon is your answer – think again.  Due to overfishing wild Atlantic salmon is now extinct, meaning the only type available at market is farmed.  Typical farmed and wild salmon have distinct variations in how healthy (or not) they are for our bodies and for the environment.  Let’s take a look at some of these considerations:

Choose your poisons: Farmed salmon is nearly ten times higher in PCB’s and other toxins than the wild variety.  The fishmeal that is fed to farmed salmon is more contaminated than even livestock feed, according to a study by the European Union.

Pollution contribution: Farmed salmon are raised in open cages, thousands of them in net-pens linked together in the ocean.  The fish pass fecal matter into the sea around them, contaminating the water with as much raw sewage as a town of 65,000 people.  A parasite known as sea lice also becomes a problem with the pens in such close quarters. Antibiotics and other chemicals are then used to treat the disease, all of which can leach into the ocean and infect other wild fish.

It takes a village: Over three pounds of small fish are needed to produce just one pound of farmed salmon.  These fish are an important food source for lots of other ocean life, such as bass, whales, sea birds and seals. Wild salmon eat fish that have feasted on red algae, providing the natural ruby color in their flesh.  Farmed salmon gets its color from red dye.

Un-health food: In addition to the other toxins that have plagued the farmed salmon, the wild variety provides more than three times the amount of Omega 3s than its counterpart.  Wild salmon are not only drug and antibiotic-free, they also have lower levels of harmful saturated fats. According to the U.S.D.A., farmed Atlantic salmon contain 200 percent more fat than wild Pacific pink and chum salmon. Aren’t we eating it for the health benefits?

The news is not all bad when you consider the options for variety in the wild salmon family.  Coho, pink, sockeye and Arctic Char are delicious and affordable alternatives to the renowned King.  When in doubt, ask your local fishmonger the origin of the salmon you choose.  Other options include wild halibut which is local in the West and in season, and California sea bass (not Chilean.)
