(CNN) — After learning that Ashton Kutcher had landed in the hospital trying to follow Steve Jobs’ all-fruit diet, CNN reader Sumday had just one question: “All I really wanted to know was why this diet was bad?”

Jobs first fell for extreme diets during his freshman year of college, according to Walter Isaacson’s biography “Steve Jobs.” Jobs and his college friend Daniel Kottke became vegetarians after reading “Diet for a Small Planet.”

Then Jobs read “Mucusless Diet Healing System” by Arnold Ehret; Ehret believed in eating nothing but fruits and starchless vegetables like spinach, carrots and cucumbers. Jobs began with two-day fruit fasts, eventually going for a week or more. “I got into it in my typical nutso way,” Jobs told Isaacson.

Ehret’s fruitarian diet, also called the Eden Garden Diet or Ehretism, is often used as a type of cleanse, according to LiveStrong.com. Designed to detoxify the system, it can do more long-term harm than good.

When you only eat fruit, you’re excluding a lot of valuable nutrients from your diet, says Marisa Moore, registered dietician and spokeswoman for the Academy of Nutrition and Dietetics.

“Protein is one of the main ones that comes to mind,” she says. “(Without protein) you lose body weight. Protein acts like a building block for your muscles and skin and organs.”

The same goes for fats, Moore says. Although they often get demonized, fats play an important role in our hormone levels and brain function.

Kutcher told reporters at the Sundance Film Festival that he ended up in the hospital with pancreas levels that were “completely out of whack.”

Fruit contains a lot of natural sugar, which needs to be controlled by insulin in the body, Moore says. It’s the pancreas’ job to release that insulin; Kutcher’s pancreas may have been overworked if his body was receiving an overload of sugar.

Many readers wondered if an all-fruit diet could have led to Jobs’ pancreatic cancer, which led to his death in October 2011. Scientists don’t know what causes pancreatic cancer, according to the American Cancer Society. Certain inherited DNA mutations might play a role, as well as chemicals in our environment or diet.

Even if you don’t overwork your pancreas, you’re probably not eating enough calories on an all-fruit diet, Moore says. That puts the body into starvation mode, which can result in serious medical conditions like osteoporosis, severe dehydration and even heart failure, according to the National Eating Disorders Association.

Here’s the bottom line: Fruit is natural. It’s nutritious. Thegovernment recommends eating 1 to 2 cups of it a day. Just don’t go all “nutso” on it.

That may partly explain why on Tuesday, Apple introduced an iPadwith 128 gigabytes of storage capacity, twice as much as any previous model.

But will the average tablet owner need that much space?

For casual users, tablets are media-consumption devices. We use them to watch movies and TV shows, listen to music, play games and read books and magazines. All those files take up memory on your internal hard drive.

Today’s high-resolution photos and videos are increasingly hogging storage, too. It’s easy to see how someone with a lot of downloaded files might eventually run out of room on a 64GB tablet.

But 128 gigabytes? That’s the equivalent of about 100 DVD-quality movies, 30 Blu-ray movies, 30,000 songs or 40,000 photos,according to this graphic by a computer store in the United Kingdom.

Everything else about the iPad announced Tuesday is the same as the current fourth-generation models: a 9.7-inch Retina display, a dual-core A6X processor, a FaceTime HD camera, 2 gigabtyes of RAM and an estimated 10 hours of battery life.

So the new device, which goes on sale February 5, is all about giving users more storage space.

That’s why Apple is targeting the 128GB iPad at professional users such as architects, doctors or audio engineers, who often work with large files (and can afford pricey gadgets).

“Companies regularly utilizing large amounts of data such as 3D CAD files, X-rays, film edits, music tracks, project blueprints, training videos and service manuals all benefit from having a greater choice of storage options for iPad,” Apple said in a news releaseannouncing the new iPad.

Some observers say the tablet’s cost — $799 (Wi-Fi only) and $929 (Wi-Fi and cellular), $100 more than the current 64GB model — isn’t worth it in an age when we can store movies, music, photos and documents on cloud-based servers instead of our own machines.

“Apple doesn’t expect you to buy a 128GB iPad, not unless you’re a professional-grade buyer, like an architect or a supervillain,” writes Leslie Horn for Gizmodo. “The 128GB iPad is like a $300/head steakhouse dinner. It goes on the corporate account.”

Other pundits noted that at $929, the top-of-the-line 128GB model costs almost as much as the base-model MacBook Air laptop ($999), which is much easier to type on.

“Apple has set its eyes on the dying infrastructure of the PC industry and Microsoft’s Windows operating system business,” writes Dan Rowinski of ReadWriteWeb. “That is really the only reason that Cupertino would unveil an iPad with 128 GB, a size that challenges many of the ‘ultrabooks’ that have become popular in the laptop market these days.”

In that way, the launch of the new iPad seems poised to stave off competition from Microsoft’s 128GB Surface Pro tablet, due February 9 in the U.S. and Canada.

When it comes to storage capacity, though, these tablets aren’t close to being the biggest. That distinction belongs to the Panasonic Toughbook H2, which retails for $3,579 and has a whopping 320GB of internal storage.
