Would you drink Coke or Pepsi for breakfast?

It appears that L.A. Times readers love their juice. Dozens of you wrote in to sound off about Sunday’s story “Nutrition Experts See Juice Glass as Half Empty.” The bottom line – that 100% fruit juice can be as unhealthy as soda – was not welcome news to many readers.

Juice To recap, the story points out that fruit juice has comparable amounts of calories and sugar as soda on an ounce-per-ounce basis. Drinking excess soda will make you gain weight, and the same is true of juice. Health experts scratch their heads when schools remove soda from their vending machines and substitute juice instead. Though juice comes from fruit, it is not nutritionally comparable because it has more sugar and less fiber. As Dr. Charles Billington, an appetite researcher and endocrinologist at the University of Minnesota, put it: “It’s pretty much the same as sugar water.”

Juice drinkers wrote in with their complaints. Among them:

If [your butt] is super-glued to the couch, you can become obese eating celery. (I doubt it – that would mean eating a LOT of celery – but in principle, you could become obese if all you ate were apples and oranges.)

And:

My Dad lived to be 96 and drank more than one glass of orange juice, squeezed fresh every day. He hooked me, but I am only 80.

One reader pointed the finger at the way juice is packaged:

Just as with soda, having a big old half gallon in the fridge leads to pouring big old glasses of it any old time -- and a whole lot of calories.

But he added:

My father in his 60's was thinking that he was so healthy drinking his Tropicana orange juice every day -- a whole quart. Then suddenly, wham!! Diabetes hit him and he almost died. This is a Yale Medical School grad very aware of medical issues. In hindsight, he realized that he had been in sugar denial.

Several readers also wrote in to say that they’ve been on to juice for some time now. For instance:

I stopped drinking fruit juice several years ago when I realized I had high triglycerides, which can be a symptom of the body having trouble processing sugar and other carbohydrates. The large amount of sugar in orange juice even makes my teeth hurt now when I try some.

A researcher from the Harvard-affiliated Joslin Diabetes Center commented:

The "healthy halo" around juice has been in great need of a reevaluation.

He pointed to this study, published last week in the journal Cell Metabolism, that found that sugar consumption reduced the lifespan of worms. (I know, people are not worms, but they are useful models for studying aspects of human health.)

If you’d like to add your two cents, please feel free to post a comment here.

The problem of excess sugar consumption certainly raises the question (asked by one reader) of how much sugar one can consume each day without getting into trouble. The answer depends on how many total calories you’re shooting for each day. A helpful guide is available from LifeClinic.com. For instance, a 2,200-calorie diet can include up to 12 teaspoons (or 44 grams) of sugar each day.

I also got questions from many readers asking whether their beverage of choice (pomegranate juice, cranberry juice) was any healthier than orange or apple juice. You can look up almost anything at this website from the Agricultural Research Service’s Nutrient Data Laboratory, part of the U.S. Department of Agriculture. Be sure to check the 1-cup option to get an accurate read on calories, sugar and other components of an actual serving size (the program defaults to “100 grams”).

Watermelon fun

Melon500

Like many last weekend, I ate slice after slice of watermelon, scrunching the fruit right down to the rind. My appetite insatiable, I took another whole watermelon and ground it up, making a pitcher of watermelon juice. And I am here to report that...wow, the melon and the juice tasted good.

Yep. That's it.

Who knows what else I'd have to say if I were a man? According to a news release from Texas A&M University, watermelon contains a chemical with Viagra-like properties. The chemical in question-- citrulline, richest in the rind of the melon--is converted into the amino acid arginine when it gets into the body. "Arginine boosts nitric oxide, which relaxes blood vessels, the same basic effect that Viagra has," says watermelon researcher Bhimu Patil of Texas A&M, in the news release.

The release doesn't refer to any studies done by the scientists demonstrating Viagra-like properties in humans or animals, or experiments in dishes with little pieces of human penile tissue, as was done for compound UK-92,480, the name that Viagra once went under.  And if arginine's the business, why not cut out the middle man and scarf it directly? Or go for protein-rich foods? (Proteins, you'd think, would have plenty of arginine, since they're made of amino acids.)

Though these are pressing issues, maybe what we're really seeing here is yet another jostle in the battle for superfruit supremacy. Already, as we reported last week, mangosteens and açai berries are facing potential healthful-fruit challenges from the decidedly-odd-looking baobob tree. And now, this.  "The more we study watermelons, the more we realize just how amazing a fruit it is in providing natural enhancers to the human body," Patil says.   

Fruit. It's good for you. Eat lots of it. Maybe we should just be satisfied with that?

Mangosteens are so yesterday

Baobab trees

Move over, goji berry! Sayonara, acai! Fickle is the consumer seeking everlasting life in a bowl or smoothie glass, and we've just gotten wind of a new fad fruit -- that of the baobab tree.

The baobab has everything a superfruit should have. Unfamiliarity. A name that's hard to pronounce. The fact that it grows far away (in various countries in Africa) and that its fruit has been eaten by ancient peoples. And lord, just look at it! I mean, seriously. Something that odd-looking has got to be good for you.

Plus, it's pollinated by fruit bats.

An article in the online food trade publication FoodQualitynews.com reports that scientists in Britain have been studying use of baobab fruit pulp in smoothies and cereal bars. A spokesperson with PhytoTrade Africa, a natural products association of southern Africa, says plans are afoot to research its "health giving properties." The fruit is reportedly high in antioxidants, and stimulates growth of good bacteria in the gut.

Of course, it's a matter of debate whether a baobab -- or any of these superfruits -- are more healthful than a proletarian apple or pear would be -- as we explored in a March 10 article about superfruits.

(Still, let's take one more look at it, shall we?)
