How to Make Dried Fruit

If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting!

Nature’s Candy

Dried fruit? Isn’t that kind of high in sugar? Well, the short answer is yes, but the long answer is that in small doses - such as in a nut-based snack mix, or sprinkled on top of a high-fat plain yogurt (e.g. Fage Total) for a sweet dessert - dried fruit can be a welcome addition to the Primal eating plan. With that said, it is called Nature’s candy for good reason, so be careful not to overdo it.

Before we get started, let’s first address why you should be drying your own fruit - especially when dried fruit is available just about anywhere (and by that we mean even the grimiest of gas stations are stocking it these days!). According to the folks over at Wikipedia, some commercially available dried fruit products are first treated with sulfur dioxide to enhance the color of the product after drying. The problem? Sulfur dioxide can trigger asthma symptoms in those with the disorder. You can avoid purchasing sulfur dioxide-treated fruit by always opting for organic dried fruit products.

Ok, now on to the good stuff - let’s dehydrate some fruit in 10 easy steps!

1. Fruit Finder

The first step? Deciding what type of fruit will work for drying. The obvious are apricots, apples, bananas, berries, coconut and plums, but be sure to give cherries, citrus peel, figs, kiwis, mangoes, nectarines, papaya, peaches, pears and pineapple a try! An even more off the wall - yet no less delicious option? Cantaloupe - it tastes just like candy!

2. Pick a Candidate

When selecting candidates for fruit dehydration, you’ll need to employ the same stringent eye you would use in the grocery store. As such, you should be picking up fruits that firm, blemish free and ripe, but not overly so (which means using fruit dehydration for the forgotten contents of your fruit bowl is not going to prove successfully!)

3. Slicing and Dicing

Preparing fruit for dehydration is no different than preparing fruit for consumption. You’ll want to wash all fruits thoroughly, particularly if the fruit you are going to use will be eaten with its skin, to remove any dirt and lingering pesticides. If necessary, pit and slice the fruit into equal-sized pieces. For larger berries or cherries, for example, you’ll want to cut them in half. Apples and Pears should be cored and then sliced into ½ inch thick slices. The key here is that all of the pieces are of similar size so that they dry at an equal rate.

4. Proper Pre-Treatment

Remember how we mentioned that store bought dried fruit often contains sulfur to make the fruit look a little more appealing? Well, there is a simple, no chemical way to pre-treat fruit that also has the benefit of restoring a portion of the vitamin C that is lost during the dehydration process. The easiest way to do this is to dip the fruit slices in an ascorbic acid dip made by combining 2 tbsp ascorbic acid - or the equivalent of 5 grams of crushed vitamin C tablets - in one quart of water. Another method is to blanch the fruit by putting slices in a steamer for five minutes then transferring them to an ice water bath to stop the cooking. Though this process is really only good for a few fruits, such as apples, pears and apricots.

You know how they say there’s more than one way to skin a cat? Well, there’s also more than one way to…errr…dry a fruit! Here are a few of our favorites:

5. Sun Drying

By far the most environmentally friendly method, sun drying is really only a viable option for those living in climates with 100 degree heat and relatively low humidity…and where you can guarantee that this fine weather will last two to four days. To do, line a cookie tray with sides with cheese cloth or a fine netting. Arrange slices on the tray and place in direct sunlight. Turn fruit once a day to promote equal drying. Some fruit drying aficionados recommend positioning a fan close by to boost air circulation and also suggest that you bring the trays indoors overnight to prevent dew from forming on the fruits.

6. Oven Drying

Yes, the oven is on for a long time, but it’s on at such a low heat, that it really isn’t that bad on the environment (or, lets face it, the electricity bill!) To dry fruit in the oven, line the racks with cheesecloth and place fruit slices on top. The oven should be set at its lowest setting, reaching a temperature of no higher than 145 degrees Fahrenheit, and the door should be left slightly open to allow any steam to escape (again, experts recommend positioning a fan close by to keep air circulating).

7. Electric Dehydration

If you’re planning on making a habit out of dehydrating fruits, it might be smart to invest in an electric dehydrator. They’re more economical than running your oven for that long and, unlike an oven, you don’t have to stay home when the dehydrator is going! Plus, it’s the fastest way to get the job done, meaning you’ll get your prunes pronto!

8. All Done

Although drying times vary based on the type of fruit, how it is prepared, and how you dry it, there are a few simple tricks you can use to test when it is done. A good way to test whether the fruit is “cooked” is to first touch it - it should feel dry but not brittle, almost taking on a leathery yet pliable texture. Then, tear a piece apart and look along the tear. If there are moisture beads, you’ll need a little more time.

9. Dried-Up

You spent all that time doing the dehydrating, the quickest way to reverse all your hard work? Store it improperly. To keep the (dried) fruits of your labor in tip-top shape, store them in a Ziploc bag or other airtight container that is then wrapped in a brown paper bag or other covering that will keep the fruits protected from sunlight. Then, store the package in a cool, dry place. If you must keep the fruits in the fridge, take extra steps to ensure that the package is airtight so that the cool moisture of the fridge doesn’t spoil the fruit.

10. Pass the Pasteurizer

Not going to get to your dried cantaloupe pieces any time soon? There is a way to extend the life of your fruit: Pasteurizing. There are two options to do this: The first is to heat the dried fruit in an oven at 175 degrees for 10-15 minutes. The other requires you to freeze the fruit for several days at zero degrees. It should be noted, however, that you’ll need a deep freezer to do this (the one attached to your fridge just won’t stay cold enough!). Once pasteurized, follow the same storage protocol as detailed above.

Final Thoughts: Fresh and dried fruit is a welcome addition to the Primal eating plan. In moderation, dried fruit can be a healthy, sweet treat. But we’d be remiss if we didn’t reiterate that, especially with dried fruit, you may want to keep an eye on consumption if you’re trying to keep your carb count within the healthy Primal range.

Dear Mark: Post-Workout Fasting

Empty Bowl

A Scrumptious PWO Meal

Before I jump into this week’s Dear Mark post I wanted to direct everyone’s attention to Andrew Rubalcava’s site, Go Healthy Go Fit. Andrew just published an interview with me. Here are just a few of the questions I answered:

Who have been your top 3 favorite bloggers over the years?

How did you get involved in physical competition such as your experience as a triathlete?

If you could give a few words of advice for those who are just beginning to enter a world of health and fitness, what would you say?

Check out the interview here, and check back on Thursday when I’ll be publishing Andrew’s guest post on how to stay healthy no matter what type of lifestyle you lead.

______________________________________________________________

For this week’s Dear Mark I thought I’d follow up on the issue of post-workout nutrition from a couple of weeks ago. I mentioned in Dear Mark: Muscle Building and Carbs that I fast once in awhile after a workout. I’ve gotten a lot of comments and messages about this point since that post. So, here’s my take on PWO fasting as promised!

As I mentioned in the earlier Dear Mark, after a workout is prime opportunity for protein synthesis. For that reason I usually do a high protein snack in the first 30-60 minutes to capitalize on that benefit. (Carbs, as you recall, aren’t necessary for the enhanced synthesis, and I don’t recommend them in any form after a workout that’s under an hour’s time.) However, I also occasionally choose to fast after a workout to maximize another physiological benefit - the rise in human growth hormone (HGH), which critically influences everything from bone density to muscle mass and organ reserve to general cell reproduction in the body’s systems.

As I’ve mentioned before in relation to intermittent fasting (IF), fasting is known to significantly increase HGH secretion. (Grok’s survival depended on the ability to hormonally kick start efficiency and preservation modes during the lean days.) Research has also consistently confirmed that intense exercise, particularly resistance training, also triggers a rise in HGH. While I can (and do) take advantage of each individual method, combining the two opportunities can maximize my body’s HGH release.

Furthermore, insulin suppresses HGH. Skipping the carb snack and subsequent insulin upsurge goes a long way post-workout. But skipping anything that might even mildly raise insulin levels (that heightened sensitivity in the muscles, you know!) can be better yet.

And I should add that I do this without worrying about a blow to muscle mass. Fasting occasionally post-workout, provided I maintain a high protein diet the rest of the time, doesn’t negatively impact nitrogen retention and protein synthesis. Just as I mentioned last week that the body won’t suffer if you don’t force reloading of glycogen stores with a shot of glucose after a workout, I’ll go out on a limb and say that you’re unlikely to waste away if you don’t fuel muscles immediately with protein as well. The fact is HGH has its own protein conservation potential. And, while the post-workout period is an optimum opportunity for protein synthesis, it’s not the sole time your body is able to use protein and provide for the muscles’ needs.

While I’m not suggesting fasting after every workout, I think it’s worth doing occasionally. (After all, Grok probably wasn’t successful with every hunt.) In the spirit of IF and recreating patterns of our primal ancestors’ lives, varying your eating/exercising/fasting practices ultimately allows for maximizing the hormonal and upregulating benefits of different physiological scenarios.

Finally, yet another means of naturally encouraging HGH release is getting a good night’s sleep. After a good fast (and a great workout), I find this part comes the easiest. Honestly, it’s the best sleep I get.

As always, thanks for your questions and comments. Keep ‘em coming!

Loathe Handles: Belly Fat Increases Early Death Risk

Keep Tightening That Belt!

Loathe your love handles? A study in the New England Journal of Medicine suggests the extra belly fat isn’t just an eyesore; it can increase your risk of an early death.

While the link between extra belly padding and health problems has been long established, this new study is the first to show such a powerful link between pant size and death risk.

For the study, researchers from Imperial College London studied almost 360,000 people from nine European countries. The average age of participants at study onset was 51. Across the 10 year study period, 14,723 study participants died.

Analyzing mortality rates by waist size, the study finds that men with waists exceeding 47 inches had rates of death double that of their peers with waists under 31.5 inches. Similar statistics were observed among women with waists exceeding 39 inches when compared to those under 25.5 inches. In fact, the relationship between waist size and death risk was so strong that when comparing people with the same body mass index, the researchers determined that every additional 2 inches on the waistline increased the risk of death 17% for men and 13% for women.

Although the researchers concede that the reasons behind the link aren’t clear, a researcher from the German Institute of Human Nutrition at Potsdam-Rehbrucke suggested that abdominal fat may be unlike other forms of fat in that it is capable of releasing messenger substances that promote the development of chronic disease.

Noting that “there aren’t many simple individual characteristics that can increase a person’s risk of premature death to this extent, independently from smoking and drinking,” the researchers recommend that people be particularly mindful of excess fat accumulation around the abdominal area. The better news? The added poundage around the middle doesn’t have to be confirmed by an expensive test or some mind numbing algorithm. Rather, you can monitor your waistline by simply keeping an eye on how your clothes fit and take steps to cut back if your waistband starts feeling particularly tight.

So what can you do to prevent the waistline expansion? The key is to maintain a healthy diet and exercise program that allows you to maintain a healthy body weight. However, since we know that even people with the same BMIs can have dramatically different body shapes, it’s important to include interventions that specifically target the waistline. For example, a recent study suggests that a diet rich in protein, red meat and fiber was best at helping to reduce abdominal fat in men. Sound familiar? Now pair it with a plan that keeps you active and adding notches to your belt (for weight gain people - get your mind out of the gutter!) and the death threats associated with an extra tire around the middle shouldn’t even be an issue!

Smart Fuel: Olives

Olives

Are you a green olive person, or a black olive person?

In that Mediterranean world which begat Western civilization, the olive enjoyed special prominence beyond its culinary properties. Roman aristocracy thought good health depended on two things: wine within, and (olive) oil without. The olive branch was the symbol of peace, and the fruit itself an emblem of wealth and prosperity. Today, the oil extracted from olives is the main draw for many - it figures crucially in Italian, Greek, and Northern African cooking, and it’s the basis for many marinades, dressings, and sauces. As Primal Blueprinters, olive oil is one of the best fats we can use, but let’s not forget about the source. Whether as snack, spread, or salad ingredient, we need to start recognizing the power and versatility of the olive itself.

Black or Green?

Black Olive

The color of the olive corresponds to the ripeness of the fruit when picked. That’s it. Green olives are picked before ripening, and black olives are picked while ripe. And because raw olives are mostly inedible, both varieties normally undergo some form of curing process, either by being packed in salt, brined, pickled, or soaked in oil (or even just water) before being eaten. Generally, green olives are denser, firmer, and more bitter than black olives. The taste and texture of any olive, however, ultimately depend on the method and duration of curation. Any olive - even a green one - will grow softer in a brine. I suppose you could think about it like this: green olives are often used as stand-alone snacks, while black olives are commonly used in cooking, on pizzas, and in salads. Of course, olives can be used in a number of ways (please share your faves!), whatever the color, but those are the usual respective uses for green and black olives.

Nutrients

Jar of Olives

As you might imagine, the health benefits of the olive are pretty much identical to its oil. You already know about the fantastic amounts of monounsaturated fat, but what about the nutrients? Olives are packed with iron and copper, and they’re a Primal friendly source of dietary fiber. They’re also rich in vitamin E - a noted antioxidant - and anti-inflammatory polyphenols and flavonoids. And really, you can’t get much more virgin than the delicate flesh of the whole, unpressed olive in all its purity. As for the green versus black question, there are no nutritional differences between the two.

Oh, and cured olives are pretty salty, so be aware of sodium content.

Recipes

The thing about olives is that they’re versatile. They pair well with martinis, wine, and cheese. They are used in Greek, Italian, Mexican, and even Chinese (as a restorative soup) cuisine. They can be blended with spices to form dips, or chopped finely to adorn salads and pizzas.

Olive Tapenade

Olive Tapenade

This can be as basic or as complex as you want. Tapenade is the perfect recipe for parties: it’s easy to make large batches and it’s hard to mess up. People will marvel at your culinary skills, when all you did was throw some stuff in a food processor and hit “On.” The basic recipe is as follows:

1 cup cured black olives, pitted
3 canned anchovy fillets
2 tablespoons drained capers
2 garlic cloves, peeled
extra virgin olive oil

To do it old school, mash up the garlic, olives, anchovy, and capers with a mortar and pestle, salt and pepper to taste, and drizzle in olive oil until the desired creaminess is achieved. Serve with vegetables for dipping (or crusty bread for your non-Primal friends).

Or, you could toss everything in a food processor and blend away. Feel free to add extra ingredients. Fresh herbs, like basil, parsley, and thyme, are frequently added to tapenades, and you can experiment with adding lemon juice, hot peppers, nuts, or even figs to your custom recipe.

Steak With Olives

Steak

Any steak works with this recipe. I like the grass-fed ribeye, personally, but you can use any piece of meat. The real star is the olive sauce. Before you make that, though, cook your steak to the desired doneness and set aside.

1/2 cup cured black olives, pitted
4 garlic cloves, thinly sliced
1/2 tsp red pepper flakes
2 tablespoons olive oil
1/2 cup chopped flat-leaf parsley

Heat the pepper flakes and garlic in the oil over medium heat, using the same pan you used to cook the steak. Stir until golden. Add the olives and cook for 2 minutes. Remove and add the parsley. Serve over the steak.

Or, if you’re feeling lazy, just grab a jar of assorted olives and feast away.
