This week: surprising heart healthy foods, calcium warnings, and comparison of hemp, chia, and flax

The annual observation of  Heart Health month always triggers a predictable parade of articles endorsing the same “heart healthy” foods: almonds, flax, salmon, red wine, chocolate.  This year, I decided to go rogue with five heart-healthy foods that you probably didn’t see on anyone else’s list, along with the reasons they deserve a place on your cardio-conscious diet. But maybe I shouldn’t assume that everyone has gotten the memo on diet and heart health. This reader’s doctor actually suggested that she start using  powdered creamer in her coffee to help bring down her high cholesterol levels.  After picking my jaw up off the floor, I made a different suggestion.

At your request, I also put together a comparison of flax, chia, and hemp seed. Are all high in fiber and omega-3s–but there are also a few important differences. Find out how these three seeds stack up nutritionally and how to use them.

Calcium was also in the news this week, with a new study linking high dose calcium supplements to heart disease.  Read my recommendations for balancing bone health and heart health.  Also, find out  how much calcium is absorbed from various foods.  Also, a tip on what to do with the liquid that sometimes forms on top of yogurt.

Thanks for all the great questions and topic suggestions. Coming up soon: Wagering on Weight Loss, and a review of the Paleo Diet!

How Much Calcium Do You Really Absorb from Foods?

Q.  For foods that are high in oxalates (such as spinach), is the reported amount of calcium adjusted for the fact that you don’t absorb it as well?

A. No, it’s not. Calcium content is based on the amount of elemental calcium in a food, without regard to how much of it gets absorbed. If you look up spinach in a nutritional database, for example, you’ll find that a cup of cooked spinach contains about 230 mg of elemental calcium. However, spinach also contains oxalic acid, a compound that binds to calcium and interferes with your ability to absorb it. As a result, only about 5% of the calcium (or, approximately 11 mg) is actually absorbed. By comparison, a cup of cooked broccoli contains just 70 mg of elemental calcium—but up to 60% of this (around 40 mg) is absorbed. Even though broccoli contains less calcium than spinach, it turns out to be a superior source.

Dairy products like milk, yogurt, and cheese are among the most potent food sources of calcium. But that’s not because the calcium is particularly well-absorbed. Only about a third of the calcium in dairy is taken up by the body, but because these foods are so high in elemental calcium, you end up absorbing about 100mg of per serving.  For those who want to dig deeper, here’s an article with lots more on the relative bioavailability of calcium from different foods. But it doesn’t have to be that complicated. The recommended intake for calcium is based on the assumption that you’ll be getting calcium from a variety of foods, some of which are better absorbed than others.

This week: the science of satiety, nutrition and hair loss, misleading nutrition labels, and more

Can’t get no satisfaction? Then you definitely don’t want to miss this week’s two part series on satiety and satiation. Part 1 is on foods that help you feel full on fewer calories. Part 2 deals with foods that help keep you feeling full longer.  If you’re trying to limit your calorie intake you want to use both of these factors to your advantage.  Plus, learn how your environment can make you more (or less) hungry!

Calorie counters may also want to check out this item on “zero-calorie” salad dressings. There’s definitely more going on here than the nutrition facts label may suggest.

In the mailbag this week, we have a question from a young man wondering whether dietary changes might help  him hang onto his prematurely thinning hair.  Also, a note from a young lady hoping to become pregnant, wondering how to get enough DHA to support healthy brain development without exposing her unborn child to dangerous levels of mercury.

Satiety vs Satiation (Part 2)

If you’re trying to lose weight—or to keep from gaining—you need to be careful not to eat too many calories. But it’s no fun to stop eating before you feel satisfied, or to be hungry again long before it’s time to eat. Fortunately, there are several things you can do to limit calories without sacrificing satisfaction.

Last week, I talked about foods that promote satiation, or the feeling of being comfortably full after a meal. If you’re just joining the conversation, I suggest you go back and review that episode first. This week, I am going to focus on factors that affect satiety, or how long you can go before feeling hungry again. If you’re trying to limit your calorie intake, you’ll want to be using both of these factors (satiation and satiety) to your advantage!

What Factors Affect Satiety?

When studying satiety, researchers might give people certain foods and then ask them to rate their appetite after 1, 2, or 3 hours, comparing the length of time it takes for people to feel hungry after they eat various combinations of foods. Another way to study satiety is to give people a certain meal or snack and then measure how much they eat at the next meal. Here’s what researchers have found:

Protein. Compared with carbohydrates and fats, protein appears to offer the greatest satiety for the fewest calories. For example, you might feel full immediately after eating a big bowl of salad greens but the feeling of fullness probably wouldn’t last very long. Adding protein to the salad, in the form of some chicken, fish, eggs, or tofu, would keep you satisfied for quite a bit longer.

Fiber. Fiber is another factor that increases satiety, or the length of time before you feel hungry after eating. For example, a glass of apple juice and an apple have the same number of calories and roughly the same amount of carbohydrates and sugar. But the apple has more fiber. As a result, the apple enhances your satiety—it will keep you satisfied for longer than the glass of apple juice would. So, in addition to including some protein in your meals and snacks, try to include fiber as well. Legumes, fruits and vegetables, whole grains, and nuts are all good sources of fiber.

Visual Cues. In last week’s episode, I pointed out that some of the factors affecting satiation are purely environmental. Eating calorie-dense foods on smaller plates, for example, can cause you to stop eating sooner. Environmental or visual cues also play a role in when you decide to start eating. Researchers went into typical office environments and put dishes of chocolate candy either right on top of the desk, out of sight in a desk drawer, or a few feet away on a shelf—so not only was it out of sight but you actually had to stand up to get to it. You can probably guess what happened. People only ate half as much chocolate when it was in the desk drawer as they did when it was out on the desk. When it was on a shelf a couple of feet away, they ate the least of all.

By the way, this effect works in reverse, as well. Making vegetables, fresh fruit or other healthy snacks more visible and convenient can increase your intake of these foods. But my point here is that you will feel the urge to eat sooner and more often if you are surrounded by food. Out of sight is not only out of mind but out of mouth as well.

Use Satiety AND Satiation to Your Advantage

I hope I’ve given you some insight into the difference between satiation and satiety, and the types of foods that promote each. If you’re trying to cut calories, be sure to use both to your advantage. When planning your meals and snacks, include foods that are lower in calories but satiating—such as raw vegetables and broth-based soups. But in addition, be sure to include foods that provide lean protein and fiber, which enhance satiety so you don’t get hungry again as quickly. I’d certainly try to limit foods (such as jelly beans or soda) that don’t provide satiation or satiety. Finally, do what you can to get your environment working for you and not against you!

Product Review: Two Thumbs Up for Better Bean Company

 

Food companies frequently ask if they can send me samples of new  “healthy” food products to review.  I usually try to fend these offers off because, quite frankly, so many of these products are just over-processed, over-priced foods wearing a health halo.  [Note to PR reps: if you send it to me, I WILL post an honest review. If I ask you not to send it, that’s definitely a hint you should take.]

However, after checking out Better Bean Co.’s website, I was eager to try their new products and gratefully accepted their offer to send some for me to sample.  I have to say: These beans are just as impressive on the fork as they are on paper.

I eat a lot of legumes. They’re a great source of protein and fiber–and an essential food group for anyone looking to cut back on meat and/or grains, reduce the carbon footprint of their diet, or save money on groceries. And with so many kinds of beans and ways to cook with them, I never get bored.

As Good As Home-made (Maybe Better!)

Better Bean products are made the way I would make them myself–with wholesome, fresh ingredients and no chemicals.  They’re  fresh-tasting, well-seasoned, and with that firm texture that you just can’t get from a can.  Of course, you’ll pay a little more for these ready-to-eat beans than you would for dried beans that you make yourself. But, in my opinion, the quality and convenience easily justify the price. A $4 carton of Three Sister’s Chili makes a heart and yummy (and virtually instant)  lunch for two.  All five flavors are tasty but the chili and the Wholly Chipotle Bean dip were my favorite.

(One request for Better Bean: I appreciated the low-waste, recyclable packaging but would love it if the lids were just a little bit more secure.)

Distribution for these new products is still limited but growing quickly. You can check the company website for stores near you.
