Make Every Bite Count

/in /by

You’re eating vegetables, fruit, whole grains, dairy, proteins foods, and oils, and you’re staying within calorie limits for a healthy BMI. Does this sound abnormal to you? Sure, we can quibble about the need for dairy or the percentage of carbohydrates, but the Dietary Guidelines for Americans (DGA) are reasonable, and they’re almost exactly the same as when they were first written almost 50 years ago.

Is there a recommendation to “make sure you eat every cookie, candy, pie, and pasta in mass quantities every day” anywhere to be found? No. Is this a responsible approach to get the nutrients you need? Yes. The guidelines also recommend foods that are specific to cultures and ethnic groups and a variety of cooking styles.

Compare that with the keto recommendations of severely restricting carbohydrates, or veganism restricting animal products of any types, or the paleo diet restricting every grain for some unverifiable theory about what people ate in the Paleolithic era. Which sounds stranger to you now?

DGA Limitations

The DGA also includes these recommendations:

  • Added sugars: Less than 5% of calories per day starting at age 2. Avoid foods and beverages with added sugars for those under 2.
  • Saturated fat: Less than 10% of calories per day starting at age 2.
  • Sodium: Less than 2,300 milligrams per day, and even less for children younger than 14.
  • Alcoholic beverages: Adults of legal drinking age can choose not to drink, or to drink in moderation by limiting intake to two drinks or less in a day for men and one drink or less in a day for women, when alcohol is consumed. Drinking less is better for health than drinking more.

The Bottom Line

Is there a lot to criticize about the DGA? Not really. Most people who do are actually criticizing the Western-style diet and the food selections people make when eating that way. Nowhere does it say that we should eat ultra-processed foods to fulfill the carbohydrate recommendations. As I’ve said, I like Cheetos and peanut butter cookies about as much as the next person, but those are not something to eat on a regular basis. As the occasional snack in small amounts, sure. But as a regular part of the diet? No. The guidelines can recommend, but they can’t control manufacturers to the extent that they produce only foods that fit within the DGA. That choice on how to follow the guidelines is laid upon your shoulders for you and your family.

Now that you know what the guidelines actually say, maybe you can make better decisions about what you want to put into your body and in what quantity. Remember the tag line of the DGA? Make every bite count. Your body, your choice.

What Are the Dietary Guidelines for Americans?

/in /by

“Make every bite count.” You might think that phrase came from one of the many nutritional gurus on the Internet or in the thousands of books written about the best way to eat. Fact is, that’s the tagline from the USDA Dietary Guidelines for Americans 2020-2025 (DGA). Do you know what’s contained in those guidelines? We often see criticism of the DGA by those gurus, but they seem to be obsessed only with the supposed high carbohydrate levels and how bad that is for us. I thought we should review the guidelines so we understand the facts.

The most important change I see is an emphasis on nutrition in a baby’s first year and then at various life stages. The main focus, whatever the age group, is to focus on meeting food group needs with nutrient-dense foods and beverages, and stay within calorie limits. Two concepts there that we shouldn’t miss: food first and don’t overeat for your health and activity pattern. A healthy dietary pattern consists of the same nutrient composition in the foods and beverages across all food groups, in recommended amounts, and within calorie limits.

Here are the core elements that make up a healthy dietary pattern:

■  Vegetables of all types: dark green; red and orange; beans, peas, and lentils; starchy; and other vegetables

■  Fruits, especially whole fruit

■  Grains, at least half of which are whole grain

■  Dairy, including fat-free or low-fat milk, yogurt, and cheese, and/or lactose-free versions and fortified soy beverages and yogurt as alternatives

■  Protein foods, including lean meats, poultry, and eggs; seafood; beans, peas, and lentils; and nuts, seeds, and soy products

■  Oils, including vegetable oils and oils in food, such as seafood and nuts That’s it. Sounds reasonable to me—how about you? I’ll talk about what is unreasonable and the most important recommendation of the DGA on Saturday.

Protein in the 21st Century

/in /by

The results of the study seemed to be definitive: animal sources of protein yield more absorption of essential amino acids (EAAs). The reason the researchers undertook the study was that the Dietary Guidelines for Americans 2020-2025 (DGA) uses the term “ounce equivalencies” when describing protein sources. From the DGA: one ounce equivalent equals one ounce of meat, one whole egg, a quarter cup of beans, or a half ounce of nuts. The researchers question whether those sources are actually nutritionally about the same. As you can probably guess, they’re not.

Defining Equivalency

The researchers demonstrated that on an equal weight basis, those categories of foods are not equivalent on the net absorption of EAAs. When looking at the EAA breakdown of each food on the USDA Food Central Database, they are not equivalent at the same weight in EAAs or in any category. The calories are not the same per serving, the fat content is all over the place, and animal sources of food contain no fiber.

I think that both the USDA and the research group would be better served by using the word standardized, but that’s not really enough, either: it must be standardized to a specific nutrient or category. If one were to standardize to EAAs, then pork, beef, chicken, lamb, and every other animal would make the list, but plant-based products would not unless the serving size were different. Both beans and almonds have EAAs, but the portion sizes would be different and so would the calories and other nutrients.

A Better Idea

We don’t live at the turn of the last century or the 1930s; we have the technology today to use protein powders and EAAs in powder form as an addition to the foods we eat. There’s no reason we can’t add more protein as our protein needs change with our age without adding the fat and cholesterol that come with animal protein. Whether you prefer animal-based protein such as whey or plant-based protein such as soy, rice, hemp, or pea protein, you can increase the amount you get every day based on your needs. The amounts you need may vary, but 25 grams of protein is a good place to begin.

To avoid any discrepancy in the EAA content between plant and animal sources, use a product that specifically contains EAAs. They’re individual amino acids that do not have to be broken down as proteins do, and they’re absorbed faster. In this case, an additional 10 grams per day is a good place to begin.

The Bottom Line

I think the focus on protein is good at any age because we’re still a carb-centric society. If everyone would just follow the DGA instead of the modern adaptation we’ve concocted over the years, everyone would end up healthier. But we do love our Cheetos and chocolate truffles, so the teaching continues. Just remember: Make every bite count!
