The endorsements for SoLo Nutrition Bars from athletes are impressive, but how does this low-glycemic nutrition bar hold up in the taste and nutrition department?

I’ve had box of SoLo Nutrition Bars sitting in my panty for a couple of months now.

My plan was to include them next round of head-to-head energy and protein bar reviews (which I still plan on doing), but then a week ago before my usual 5K run, I needed a quick pick-me-up.  A protein shake just wasn’t cutting it, so I decided to dig in early and try out one of the SoLo Bars.  Afterall, if they are good enough for Paul Tichelaar, member of the Canadian Olympic Triathalon Team, I figured they’d be fine for my measly little 3.1 mile run.

So I gave in, broke the seal on the box, and grabbed a Chocolate Charger.

Who Is SoLo Nutrition?

SoLo Nutrition Bars are manufactured and marketed by SoLo GI Nutrition in Edmonton, Alberta, Canada.  According to the company’s website, SoLo GI Nutrition is planning on developing a series of low-GI specialty performance foods and snacks, with SoLo Nutrition Bars being the first of these products.

SoLo Nutrition Bars: High Performance Nutrition?

SoLo’s unique claim to fame is that unlike many energy bars, the SoLo bars are formulated to reduce glycemic load on the body. Glycemic load is a measure of how a carbohydrate raises blood glucose (blood sugar) levels.

While this might seem like a marketing hook, there are actually some very solid, practical nutritional reasons why you might want to choose a nutrition and energy bar that minimizes blood glucose spikes. While blood glucose spikes can deliver a quick burst of power, rapid increases in blood sugar levels also have a tendency to cause energy crashes later on — exactly not the thing you want to happen during any type of endurance activity, like running, biking or even working out at the gym.

The manufacturers of SoLo Energy Bars claim that their particular low-glycemic nutrition bars are formulated to have minimal impact on blood sugar levels, providing more sustained energy to power your performance, exercise or endurance activity. They call this “Controlled Energy Response”, which is really just marketese for “slow-burning carbs.”

What you need to understand is that most energy and nutrition bars are extremely high in simple sugars, which make them suitable for post-workout nutrition when insulin sensitivity is increased and the body can more effectively utilize carbohydrates.

However, the high sugar content doesn’t make them as well suited as a pre-workout snack, when complex carbohydrates are the preferred source of sustained energy. And most energy bars are also too high in simple sugars to make them a smart choice for in-between meal snacking at the office. In fact, some “nutrition” bars are so high in sugar, that you’d be just as well off to grab a Snickers bar.

SoLo claims that their nutrition bars cause blood sugar to rise more slowly than the average energy bar, and those levels are sustained for longer periods of time.

According to SoLo’s literature, the first rise in blood sugar with a SoLo Bar occurs over a period of about 60 minutes, and then begins to trail off gradually over 180 minutes.  This is much less pronounced than the spike you see with high-sugar, high-glycemic energy bars, where the initial blood sugar spike takes place in a very short window — typically within 30-40 minutes of ingesting the bar, and then drops back to pre-consumption levels within 60-90 minutes.

What is Whey Protein Powder and Do I Need It? | Diet and Nutrition

April 22, 2008 on 7:18 pm | By Matt | In Diet and Nutrition | 10 Comments

Find Out How Whey Protein Powder Went from Dairy Underdog to Nutritional Superstar

Whey protein seems to be everywhere. 

One of the top selling (and most heavily-marketed) nutritional and sports supplements on the market today, whey protein turns up as an ingredient in everything from smoothies to nutrition bars to high-protein cereals.  Personal trainers often include whey as part of their clients’ diet plan, smoothie bars offer it mixed with ice and fruit, and aspiring bodybuilders and soccer moms alike seem to have found a permanent place for a tub of whey protein powder in their pantries.

But what exactly is whey protein powder? Where does this stuff come from? And do you really need it?

A Brief History of Whey Protein

Whey is a natural by-product of the cheese-making process. Milk contains two primary proteins: casein and whey.  Whey composes about 20% of milk proteins, and casein comprises the remaining 80%. So when you drink a glass of milk, you are consuming both casein proteins and whey proteins.

During the cheese-making process, an enzyme called rennet is added to milk to curdle it. The curds are used to make cheese, and the remaining liquid is whey.

Historically, this liquid was considered more-or-less useless. Indeed, the dairy industry had so much excess whey that they struggled with disposing of the surplus. Some of it found its way into swine or cattle feed, where it appeared to produce larger, meatier cows or pigs, but a great deal of it also ended up in the landfill.

Which was really a shame, because the cattle farmers were on to something. It turns out that whey is extremely rich is three milk proteins – specifically beta-lactoglobulin (~65%), alpha-lactalbumin (~25%), and serum albumin (~8%) — which are more easily digested by the body than any other protein, including the holy grail of protein, eggs.

There was just one problem: Whey in its naturally occurring form is a sloppy, liquid mess.  It also has very little flavor. Trying to sell the world on a great protein source that has to be refrigerated and doesn’t have much taste would challenge even the best marketer.

Enter modern technology.  Scientists figured out a way (no pun intended) to “dry” and powder-ize whey, while still maintaining it’s basic nutritional profile.  The result was whey powder, which could be reconstituted in liquids while still preserving its protein values.

The rest, as they say, is history.
