Protein Content of Common Foods

This table shows the amount of protein per serving of several common foods.

Note that the standard serving size for meat is 3 ounces, which is considerably smaller than the portions you may be used to seeing.   A 3-ounce serving of meat is about the size of a deck of cards.

Is collagen protein safe and effective?

Naomi writes:

When opening a new container of Vital Proteins Collagen I saw a warning about possible lead content. Should I change my choice of collagen or stop using it altogether?  I am 65 and thought it would be beneficial for my hair and skin.

It’s hard to know for sure without a chemical analysis, but this warning may just be a corporate cover-your-hiney thing. I don’t think you necessarily need to throw away your new (and probably fairly pricey) container of collagen protein. But I’m also skeptical about its benefits for joints, skin, hair, or nails.

Six Ways to Make Your Diet Healthier (for the Planet)

Earth DayHappy Earth Day!

These days, we’re more conscious of how our dietary choices affect the health of our planet. But it gets complicated.  Sure, buying organic products helps reduce the amount of pesticides and artificial fertilizers that are applied to the ground.  But what about the environmental impact of transporting organic produce thousands of miles from its source to your table? How about all the energy it takes to process, package, and transport the organic convenience foods and all-natural junk food that fill the freezers and shelves of high-end whole-foods grocers? And to bring the conversation back to nutrition for a moment, how nutritious do you think those organic sugar-frosted corn flakes really are?

In honor of Earth Day, here are six ways to make your diet healthier for your body and the planet. Continue reading “Six Ways to Make Your Diet Healthier (for the Planet)” >

Six Free Apps That Will Make Meal-Prep Easier

Though applications are supposed to make your life easier, sometimes finding the right app can be a challenge. A “meal planning” search in the App Store yields pages of tools that claim to help you conquer the grocery store, step up your lunchbox game and make peace with your plate, but how can you know which apps are actually effective? After lots of downloading and deleting, I’ve put together a list of six free apps that have allowed me to spend more time enjoying my food rather than preparing it. These apps are available for both iPhone and Android users.

#1. Instacart: Best for buying groceries when you don’t have time to shop

As a nutrition coach in University of Maryland’s Health Center, I’ve found that my clients who grocery shop regularly are more likely to meet their nutritional goals compared to those who do not. This makes sense, as it’s pretty hard to eat healthfully if you lack nutritious foods in your home. With the Instacart app, you can have fresh produce delivered to your home with the literal flick of your finger. Not having time to make it to the grocery store will no longer be an excuse for not eating healthfully.

 

After typing your zip code into Instacart, a list of stores in your area will come up on your screen. After selecting a store, you can use the search bar to quickly find and order specific items, or, for a more authentic grocery store experience, you can add items to your cart as you peruse the different categories. You can also access Instacart online. Though the Instacart app is free, the order must be at least $10 to be eligible for delivery, and there is a $3.99 delivery fee (some of this money goes toward tipping the driver). You can subscribe to Instacart Express ($9.99/month or $99/year) to avoid this fee on orders above $35. Have fun portable grocery shopping!

Quick Guide to Complementary Protein Sources

In this week’s Nutrition Diva podcast, I talk with protein researcher Douglas Paddon Jones about whether or not there’s any benefit to combining complementary plant-based protein sources at the same meal. Contrary to a lot of the conventional wisdom, which claims that it’s sufficient to get all of the essential amino acids over the course of a single day, Dr. Paddon Jones argues  that a meal-based approach to protein nutrition will enhance the ability to build and maintain lean muscle tissue.

This doesn’t mean you have to tally up and micro-manage each individual amino acid. The following chart shows how to choose meal components that will ensure complete proteins at a meal.

If you consume only plant-based proteins, you may also want to increase your total protein intake by 10-20% to compensate for the lower digestibility of these plant-based protein. 

The Recommended Daily Allowance for protein is 0.8 g per kg of body weight (or 0.36 g per pound). Strict vegetarians may want to aim for a minimum of 1 g per kg (or 0.45 g per pound).

These are these are minimum recommended intakes. Research suggests that there may be benefits to higher protein diets, especially for athletes, the elderly, those recovering from surgery or illness, or during weight loss. If you’re in any of these groups, you might want to aim for something closer to twice the recommended minimum.
