Double Chocolate Brownie is my new favorite flavor of Balance protein bar.
I believe that this same kind of bar had another name before, but I've forgotten it. According to the official web site for Double Chocolate Brownie Balance bars, it's a new variety.
It tastes delicious, especially to sweet tooths who love chocolate, which includes me, and best of all it's one of the Original Balance Bar line, which means it is fully Zone-compatible. Unfortunately, this is not true of the Balance Gold, Balance Bare and Balance Carbwell lines of bars.
It's hard to describe, but it's all chocolate. The core is much like a chocolate brownie. It does have chocolate chips on top, and is covered by a kind of chocolate cream. So it basically is a candy bar that's healthy for you.
It does have a true Zone balance composition of 40% carbohydrates, 30% protein and 30% fat, for true Dr. Sears Zone diet 40/30/30 nutrition.
You can eat these meal bars all day and still stay in the Zone.
You can tell from the site and the packaging that the news about Vitamin D is getting out to many people, because although that's just one of the nutrients Balance puts in its meal replacement bars, it's being emphasized.

According to the label, one bars gives you 25% of the government's Required Minimum Daily Requirement. The RDA is, I believe, 400 units. That's the amount that multi-vitamins have contained for the past forty years until recently, even those bought in health food stores.
So one of the protein bars contains 100 units of Vitamin D. That means it's not a primary source of the sunshine vitamin. That actually is sunshine. But it's also true that in the temperate latitudes far removed from the equator, we can't get enough sunshine, even on days when the sun actually shines. In winter (summer in the southern hemisphere), that can not happen for days on end.
So any Vitamin D is good for you, but you shouldn't rely on these Balance protein bars to provide all that you need.
However, their main benefit is to keep you in the Zone. That is, to keep your hormones is good balance, so your insulin levels stay high enough to keep your body nourished, but not so high that your body is storing fat, and other hormonal changes are negative for your health.
Excess insulin is bad for your health and longevity, and that's why Balance Zone bars are so important. It's difficult to eat nothing but Zone meals and snacks for months on end, in the typical modern lifestyle.
I find these bars very convenient. My one complaint is that Wal-Mart doesn't carry them, only the Schnucks store where I buy groceries. I'm lucky I did see them, because the other Schnucks store in town didn't have them when I looked a month or so ago.
I have to pay $1.29 each on Schnucks which is more expensive than Wal-Mart, which charges only $4.78 per pack of six. I can buy them online, and the price appears to be about the same when shipping is figured in.
However, the company recommends using Coolship, to keep them from melting, but that seems excessive to me. I haven't had a problem ordering Balance Bars through Amazon. It may make sense when the package could be exposed to summer heat, but right now I doubt if they'd melt on me in transit.
But for now, it's easier to buy my Double Chocolate Brown Balance bars at Schnucks. If they start failing to replace them, I'll have to go online.
