The Great Nutrient Debate!


07 Nov

Originally published by FA

Sure, fruits and veggies are nature’s potent pharmacy, right?

You bet your sculpted ass they are!

But what’s the best way to get at that goodness? Should we juice it, mash it, or supplement it?

Silence.

Fruits and veggies offer a variety of nourishing vitamins, minerals, and antioxidants that are hard to find anywhere else in their purest form, but their preparation can have an impact on their nutrient make-up. Some berries when microwaved, for example, have their antioxidant potency increased. Other types of fruits and veggies, however, lose a large amount of their nutrients when cooked.

It’s best to keep them in the purest form possible so you don’t lose any of that precious cargo — specifically, antioxidants.

What are Antioxidants and Why Do I Need Them?

Everywhere you go nowadays, people are talking about antioxidants. Whether they’re your reason for eating dark chocolate, or why you’re spending hundreds of dollars on berries from a remote island that you have to charter a plane from someone named Fernando to get to.

First, let’s just talk a little about antioxidants and the basics of what they do.

Antioxidants fight off free radicals in the body that cause oxidative stress. Free radicals are chemically active atoms or molecular fragments that have a charge due to an abnormal number of electrons. They can cause damage in your cells, proteins, and even DNA.

It’s not possible to avoid free radicals forming in the body because they’re sourced from so many things. From pollution to exercise, we’re affected by them daily.

Antioxidants help stop the process of oxidation in our bodies by neutralizing the free radicals. Vitamins A, C, and E, beta-carotene, selenium, and lycopene are the most recognized items found in food with antioxidant activity.

Research keeps showing us that we benefit from natural sources of antioxidants, and time and time again, supplemental antioxidants don’t live up to their hype. Could it be that the acai berry juice filled to the brim with sugar isn’t going to save us after all, and that in fact it’s just the berry itself we need to be eating?

Marion Franz, MS, RD, CDE, a nutrition consultant and contributing author of nutritional guidelines for the American Diabetes Association (ADA), had this to say, “Supplements focus on suspected benefits from individual nutrients, when the benefits of a particular food may come not just from an individual nutrient, but from a combination of nutrients in the food.”

Also, it’s been shown that you need a variety of different fruits and veggies daily to get the full spectrum of necessary nutrients. If you’re just getting your daily servings from apples and broccoli, you need to branch out to the other isles in the produce section.

But it isn’t just antioxidants that like to float the route of whole foods.

Lyle McDonald has done extensive research on the issue and has stated that, “I have this hunch that nutrients in food are not only absorbed better (bioavailability), but utilized better by the body. In some cases, this is clearly due to the structure of the nutrient, for example heme vs. non-heme iron, with heme iron (found in red meat) having something like a ten times better absorption rate than non-heme (found in veggies).”

He also theorized that taking food supplements alongside foods that have similar nutrient content (i.e. taking your vitamin C while eating an orange) could even improve the absorption rate of the supplement. Meaning that if you want to get a super bang for your buck, try eating your fruits and veggies with a refreshing glass of Biotest’s Superfood.

Timing Your Antioxidants

Exercising increases oxidation in our bodies because we’re exerting more energy, causing us to need more oxygen. So, to a degree, we’re inflaming our body when we lift.

Inflammation is a highly controversial thing not only in weight lifting, but in health and disease conversations all over the world.

Remember that antioxidants fight oxidative stress, but it’s that very stress that causes our muscles to break down and grow again. If we hinder the recovery process too much, then we may be victims of our own overreaction.

While the overall goal is to decrease inflammation, we do benefit from some inflammation post-workout.

The best fix? Leave a good three to four hour window for antioxidant consumption pre- and post-workout to be on the safe side.

Squeeze More, Get More?

Now that we’ve crowned whole foods as king, especially for antioxidants, let’s talk about your other options and if they’re even worth your effort.

First, let’s just go ahead and get this out there: If you’re getting your veggies, fruits, or vitamins from processed, pre-made juices — then you need to change up your diet.

I know you’ve seen one of the various V8 commercials. The three I’m most familiar with feature an attractive young mom eating fries; a fit, handsome husband opting for meat and bread; and a chubby, balding man ordering food from a drive-thru. None of them are having vegetables with their meal, so they get hit in the head by a loved one or an overly judgmental drive-thru lady.

I’m sorry, but holding the lettuce, tomato, and onion at McDonald’s might not be such a bad idea.

When I get my serving of veggies, I want them fresh, clean, and tasty, not overly processed, covered in sodium, and “enriched” with vitamins. So, if you think that getting your serving of veggies from V8 is cutting it, you’re dead wrong!

The same goes for all of those fruit-based juices filled with antioxidants. You’re losing so much getting it in that form, and most of the time you aren’t even getting an amount that comes close to what the labels says.

Luckily, by law, “fruit juice” is only to be used to describe a beverage that’s 100% fruit juice. However, fruit juices combined with other ingredients, like high-fructose corn syrup, are called a “juice cocktail” or “juice drink.”(1) Also, according to the FDA, the use of the word “nectar” when describing a beverage is acceptable for a diluted juice that contains fruit juice or puree, water, and sweeteners.(2)

So, if you’re going to drink a processed juice, make sure you read the label and aren’t getting something that’s complete crap.

I’d also like to note that fruit juice labels may be misleading because of companies actively hiding their actual content. This will continue to get worse as more and more people are trying to have a healthier diet, thinking that juice will make up for the three large pizzas they ate the night before.

Phrases like “no added sugar” are placed on labels, and normally the products are made from “reconstituted concentrate,” which is naturally occurring fructose in the fruit. This has a similar effect to sugar, and the jury is still out on how good this may be for you.(3)

Food distributors do shady things like this often, like saying “no trans fat” and actuality meaning “no trans fat per serving because if it’s less than one gram in a serving, that means there’s none.” Sure, trans fat may or may not be the ultimate evil, but funny they’re trying to hide it so hard, isn’t it?

In short, it’s best if you know where your juice is coming from, or that it’s just coming from fruit in the first place.

Time for a Smoothie

Now, juicing at home is definitely a much better option than getting processed juice, but it’s still lacking.

You lose so much natural fiber, which we all need more of, and a lot of fruits and veggies are robbed of their nutrients when exposed to air for any length of time. Studies have shown that once the fruit has been juiced, its antioxidants start to react with oxygen free radicals, losing their health benefits.

So, if you’re going to juice, make sure to drink it up quickly so you lose as few of those precious nutrients as possible.

The perception of fruit juice as being equal to the consumption of fresh fruit has been questioned mainly due to the lack of fiber and the processing they endure. The high amounts of fructose in fruit juice when not consumed with fiber have been suggested as a contributor to the growing diabetes epidemic.

While it seems that pill popping is a roll of the dice, and juicing is a squeeze and tease, what are we to do?

Try smoothies!

Now, just like with juicing, you want to drink this fresh, so no making it the night before and then having it in the morning.

There’s a small breed of “researchers” that talk about the need to utilize enzyme function to break down food, and that removing this process from the stomach can decrease metabolic burn. I haven’t seen a study on this, but I’ve seen a lot of anecdotal claims.

For those who are looking for a drink fix, skip the juicing and go with the smoothies instead. This is such a better option because you’re getting more nutrients than if you juiced, and you’re getting all of the needed fiber. They’re also just really yummy!

Here are a few recipes to enjoy:

Strawberry Sunrise

1 orange (around 160 grams)
1.5 cups of frozen strawberries (around 200 grams)
Half a frozen banana (around 60 grams)
Half a cup of pineapple (around 60 grams)
Half a cup of frozen spinach (around 60 grams)
4 ounces of milk (or liquid of your choice)
1 scoop of Biotest Superfood

Berry Breeze

1 cup of frozen blueberries (around 140 grams)
1 cup of frozen raspberries (around 140 grams)
1.5 cups of frozen peaches (around 200 grams)
3-4 slices of watermelon (around 200 grams)
Half a cup of frozen spinach (around 60 grams)
4 ounces of milk
1 scoop Biotest Superfood

For both recipes, add water or milk to taste, and add Metabolic Drive to create a super shake.

If needed, you can also add a low or no-calorie sweetener.

With the fruit, you can buy it fresh and then freeze, or just buy frozen. This way you don’t have to add ice and water down the smoothie.

Whole Foods for a Whole You

A strong argument has been made for whole foods, or at least properly pairing your supplement intake with them.

Next time you think about passing on some of the best the nutrition world has to offer, think about all the things you’re denying yourself.

Vitamin D: The Real Facts,Truths, and Sources of The Sun Vitamin

When you research, read, and watch the news as much as I do, you can see the new nutrient and supplement trends coming a mile away. Sometimes they’re valid, other times they aren’t. I can say for certain to buckle up and hop on the D-train because it’s here to stay. In fact, this isn’t a newly found miracle baby; this is an age old savior that we’ve been neglecting.

What is Vitamin D?

vitamin D

Vitamin D is a fat soluble steroid hormone (and if we weren’t playing fast and loose with the terminology, it technically isn’t a vitamin at all). The main job of vitamin D is to maintain normal blood levels of calcium and phosphorus. Note that’s the main job. It’s said that over 200 genes are affected by vitamin D. It doesn’t matter where you turn, its uses are everywhere. Bone, heart, insulin, depression, pain, happiness, cancer, fibromyalgia, thyroid… you name it, vitamin D plays a role.

Michael F. Holick, a leading researcher on the importance of vitamin D, has said that “Vitamin D deficiency is the disease of neglect.”

And he couldn’t be more right.

The cure for rickets — a widespread epidemic in the children of the softening of the bones — was found by sticking children on the roof of a building. Can you sit there and take that in for a moment? An illness that was making the limbs of children turn into mush was cured by the sun.

You may wonder what this has to do with you,  but bones should be your pride and joy. Not to mention the fact that recent studies show an alarming rate of newborns and mothers are becoming more and more deficient. Are past problems coming back to bite us in our vitamin-deficient rears?

Beyond just bones, being too low in vitamin D can lead to a decrease in thyroid function. Although not directly involved in synthesis or secretion, a deficiency can produce increases in the levels of parathyroid hormone.

On the wellbeing side, an increased occurrence of depression and a decrease in mental focus have been found time and time again. There are also links that have shown women who supplement with vitamin D may lose fat easier than those who don’t.

Currently, the desired levels are 30 to 75 ng/mL-nmol/L, and anything less is seen as deficient, though higher doesn’t necessary mean you’re at a toxic level. The concern is for consistent levels above the 200 range.

The bottom-out number should really be 30; however, we’re seeing study after study show that levels are constantly hitting below this all around the world, and the aftereffect is becoming an epidemic.

ng/mL nmol/L Status
< 11 < 27.5 These levels suggest severe illness, usually seen in rickets or sick infants.
< 10-15 < 25-37.5 While not directly or instantly crippling, these levels overtime may contribute to illness both acute and chronic.
≥ 30 ≥ 75 Seen by some to be the desired range and achieving of optimal health.
Consistently > 200 Consistently > 500 Could be toxic and lead to hypercalcemia and hyperphosphatemia.

How Do You Get It?

Vitamin D is the “sun vitamin,” meaning that you should receive 80 to 100% of your intake from the sun. When ultraviolet (UV) rays hit the skin, they’re absorbed and converted, setting into motion your body’s process of creating vitamin D. In truth, this should be the end all for receiving your daily intake.

However, things just aren’t that simple.

What About Food Intake?

Vitamin D can be found in small amounts in certain fishes, fortified milks, and egg yolks.

The problem is that the intake would have to consist of very high levels and multiple times daily to give you the effects you need. It also would depend on the quality of your food. With fish, for instance, it’s been shown that farmed salmon (fish raised in tiny boxes eating crappy fish food) held at least 25% less vitamin D than wild-caught salmon.(1)

Take-home point being, if you think that the Wal-Mart fish nutrients are doing something for you, think again. What they eat is what you eat. As well, the fortified milk and cereal claims of vitamin D can be off by as much as 80% of what the label says.

Here’s a chart that gives you a general rundown of food sources for vitamin D:

Food IU per serving Percent DV
Cod liver oil, 1 tablespoon 1,360 340
Salmon, cooked, 3.5 ounces 360 90
Mackerel, cooked, 3.5 ounces 345 90
Tuna fish, canned in oil, 3 ounces 200 50
Sardines, canned in oil, drained, 1.75 ounces 250 70
Milk, nonfat, reduced fat, and whole, vitamin D-fortified, 1 cup 98 25
Margarine, fortified, 1 tablespoon 60 15
Ready-to-eat cereal, fortified with 10% of the DV for vitamin D, 0.75-1 cup (more heavily fortified cereals might provide more of the DV) 40 10
Egg, 1 whole (vitamin D is found in yolk) 20 6
Liver, beef, cooked, 3.5 ounces 15 4
Cheese, Swiss, 1 ounce 12 4

Selected food sources of vitamin D (2,3)

Differences in Vitamin D

Vitamin D comes in two main forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). There’s a D1, D3, and D5, but in short, their importance and our control of them isn’t the main topic here.

Vitamin D2 is made by the UV irradiation of ergosterol in yeast, and vitamin D3 is made by the irradiation of 7-dehydrocholesterol from lanolin and the chemical conversion of cholesterol.

It’s suggested that D3 is far superior to D2 at raising levels in the body and holding them higher for extended periods of time.(4,5) Because of this, if you’re going the supplement route for your intake of vitamin D, D3 is the winner of the group.

The overall goal of vitamin D is to raise serum levels in the body and do so as best as possible. To date, both D2 and D3 supplements at prescription-grade levels have shown to do this. D2, however, has been shown to be toxic at higher levels. (It should be noted that you can’t achieve toxic levels of D in the body with just the sun.)

How Long is Too Long in the Sun?

This is the tricky part and most often misunderstood. Obviously, there’s plenty of data to back up that being in the sun too long without protection can lead to skin cancers. The flipside is that being in the sun too little might lead to cancer as well.

You may think that applying some sunscreen will get you the best of both worlds, but sadly sunscreen has been shown to block upwards to 95% of vitamin D uptake from the sun.(6)

What are you to do?

A good solution is to spend fifteen minutes in the sun and then apply your sunscreen. It’s suggested that fifteen minutes a day can be enough. However, for a lot, that isn’t the case. And unless you’re living below 42 degrees North latitude (a line approximately between the northern border of California and Boston), in the wintertime you aren’t going to get it at all.(7)

Studies also show that if you’re African America or Hispanic then you need near double what Caucasians need.(8,9)

The Do’s and Don’ts of Vitamin D

If you find yourself stuck inside, above the magic line, or of darker skin, then you might need to look at better options of getting vitamin D.

1. Don’t be obese: Obesity blocks vitamin D intake by as much as 55%.

2. Don’t be scared of the sun: We’re a culture of extremes and look at where it’s got us. You need some sun, so don’t be afraid of it. Just call it quits before you burn like a lobster.

3. Do eat cod liver oil: Cod liver oil in supplement form is a really simple and easy way to get in lots of D3 during those months when you may not be able to.

4. Don’t be scared of the tanning bed: If you’ve ever known a friend with an iguana or turtle, then you know that in order to survive they need those ultraviolet exposures. Well, so do you!

Exposure to tanning beds resulted in a 100% increase in blood concentrations of vitamin D.(10) The problem is, just as with the sun, people take things too far. It’s a great way to get what you need in the winter months, but the same “don’t overdo it” rules apply.

5. Do get tested:
In general, you should be getting a full vitamin and mineral testing every six months. Is it time for a checkup?

6. Do hit the numbers: While 400 IU is the recommend dosage, there’s nothing wrong with getting 1,000 IU, especially from D3, and namely during the “off season.”

7. Do take this seriously: I’m not usually one for dramatics, but there are so many low level health problems that can lead to higher level problems, and issues from a vitamin D deficiency can be really simple to solve.

Take it seriously; get in your sun, get in your oils, and take advantage of the problems you can fix every chance you get.
