Protein powders are often a cost-effective, quick way to incorporate more protein into your diet. Protein powder can provide a high-quality snack with approximately 20–30 grams of protein for refueling after a tough workout or eating on the go. Depending on the protein supplement you buy, it may actually be more cost-effective to use a supplement than purchase more pricey foods like meat and fish. Whey protein powder is about $10–15/pound and has a longer shelf life than fresh, protein-rich foods.
While protein bars provide a quick, mindless, no-mix way to get post-workout nutrition, they generally contain more calories, carbs, fat and sodium. Bars vary widely in the amount of carbs they contain. Choose higher-carb bars (>20 grams per serving) when you engage in vigorous aerobic activities (running, swimming, biking) for a duration of more than 90 minutes and lower-carb bars (<20 grams per serving) for non-aerobic activities.
WHAT’S IN PROTEIN SUPPLEMENTS?
When it comes to protein, quality matters. This is why scientists came up with the “protein digestibility corrected amino acid score” (PDCAAS). This score tells you protein quality as measured by: 1) how “complete” the protein is and, 2) how easily digestible it is.
The PDCAAS scores protein sources from 0–1 with 1 being the highest. A score of 1 is assigned to egg white, which contains all 9 essential amino acids and is easily digested and absorbed. Ideally, your protein powder supplement should score as close to 1 as possible, but this depends on the source of protein it’s made from.
3 COMMON PROTEIN POWDER SOURCES
1. WHEY AND CASEIN (PDCAAS=1)
These are proteins extracted from milk and are complete proteins, easily absorbed by the body and relatively inexpensive. Plus, these milk proteins contain branched chain amino acids (BCAAs) to encourage muscle building during strength training. The downside is this protein source is unsuitable for vegans and people with lactose intolerance or milk protein allergies.
2. SOY PROTEIN (PDCAAS= 1)
Soy protein is plant-based, contains all nine essential amino acids and is inexpensive. Soy protein powder is a great alternative for vegans who can’t take whey or casein; however, it isn’t suitable for those with soy allergies.
3. OTHER PLANT-BASED PROTEINS
Pea (PDCAAS=0.69), rice (PDCAAS=0.47) and hemp (PDCAAS= 0.46) proteins score low on the PDCAAS because they don’t provide all nine essential amino acids when taken as a stand-alone source, and the rice and hemp proteins are not readily digestible. For this reason, they are usually found together in a plant-based protein powder supplement mix. While these mixes can be hypoallergenic, we’d still suggest whey, casein or soy if you can stomach them.
3 TIPS FOR FUELING WITH PROTEIN SUPPLEMENTS
1. READ THE INGREDIENTS
This is usually not a pretty place, but if you’re going to eat it, then read about it. Protein bars can hide processed fibers, sugar alcohols and artificial sweeteners. Make sure you’re OK with these before biting into one.
If you’re considering protein powder to increase muscle size and strength, whey is the way to go – as long as you don’t have lactose intolerance. It’s an inexpensive, high-quality protein that is quickly accessed by your muscles.
2. DON’T FORGET TO LOG
Remember that supplements (and anything you mix with them) have calories, too, and can contribute to excess weight gain if you aren’t careful, especially since some bars are meant to replace a whole meal — and they have the calories to do it.
