[Updated March 9th] Thanks to Darya Pino from SummerTomato.com, Ben Greenfield of BenGreenfieldFitness.com, and Gloria Tsang of Healthcastle.com, the folks at Vokle.com, and all of you who joined us for our live round-table on breakfast. It was a fascinating discussion! For those of you who might be interested in looking at some of the primary research that we discussed, I’ve posted links to those studies below.

Fish Oil to Reduce Cholesterol?
Q. I’ve listened to your podcast on fish oil and omega-3s and shared it with some people I know who take fish oil. But today my physician told me that my “bad” cholesterol is borderline and that a way to get it down without statins would be to take fish oil twice a day. I’m wondering what you think about that.
A. In the podcast you’re referring to, I was talking mostly about prophylactic or preventive use of fish oil supplements. Here’s the point I was trying to make: Taking fish oil supplements, which are high in omega-3s, is one way to balance out diet that’s too high in omega-6 fats. But another way to improve that balance is to reduce your intake of omega-6. Reducing omega-6 intake (which come mostly from vegetable oils and processed foods) can reduce the need to take fish oil supplements.
Sugar: The Bitter Half-Truth?
Q. Are you familiar with Dr. Robert Lustig’s presentation on fructose, called “Sugar, The Bitter Truth” ?
What’s your opinion on this? Shouldn’t pure fructose sweeteners (which are marketed as low calorie) be banned? According to this presentation, wouldn’t it be a good idea to substitute all sucrose with a larger amount of maltose?
A. Although I respect Dr. Lustig and his work, your questions are the perfect illustration of just how badly this viral video has confused the issue among consumers (and more than a few professionals). Here’s what always seems to get lost in the biochemical mumbo-jumbo: Dr. Lustig’s observations apply to the dangers of excessive fructose intake.
This Week’s Podcast | Can You Get Too Many Antioxidants?
Recent research has me rethinking the conventional wisdom on free radicals and antioxidants. Learn how free radicals benefit your health and get my latest recommendations on how to get the right amount of antioxidants without going overboard in this week’s podcast.
Avoiding Pesticides: Beyond the Dirty Dozen
People buy organic foods for lots of reasons: They are produced without chemical fertilizers and pesticides and (in the case of animal products) without hormones and antibiotics. But a 100% organic diet may not be possible. So people often ask me which foods are most important to buy organic. Here’s my short list, in order of priority:
Fruits and Vegetables
Of all food types, pesticide residues are most common in fruits and vegetables. According to the FDA’s most recent (2007) Pesticide Monitoring Program Report, pesticides were detected in slightly over a third of all fruits and vegetables (domestic and imported) tested.
You’re probably familiar with the Environmental Working Group’s list of the Dirty Dozen–12 commonly eaten fruits and vegetables with the highest pesticide residues. I talked about the Dirty Dozen in my podcast on getting the biggest bang for your organic dollar. Continue reading “Avoiding Pesticides: Beyond the Dirty Dozen”
Asian Style Broccoli Salad
Serves 4
Chilled broccoli salad is a super-nutritious side dish. But instead of a heavy mayonnaise-based dressing, try this delicious Asian-inspired alternative instead!
2 bunches fresh broccoli (about 6 cups chopped)
1/2 red or vidalia onion, diced
2 tablespoons seasoned rice vinegar
1 tablespoon honey
2 teaspoons minced fresh ginger
1 teaspoon soy sauce
1 teaspoon toasted sesame oil
1/4 cup blanched almonds, slivered or chopped
5 Compelling Reasons to Hit the Hay
The usual prescription for a healthy lifestyle includes a healthy diet and regular exercise. But there’s another critical element that often gets overlooked: Sleep. Experts recommend a minimum of 7 to 8 hours of uninterrupted sleep every night. Yet most American adults report that they get 6 hours of sleep or less on most nights.
Need a little extra motivation to make getting enough sleep more of a priority? Here are five compelling reasons to turn off the television or computer and hit the hay:
Reason #1: Skimping on sleep increases stress hormones, which accelerates the aging process.
Reason #2: Under-sleeping increases insulin resistance, which is a risk factor for Type 2 diabetes.
Reason #3: Sleep deprivation affects hormones that regulate appetite–making you feel hungrier than you would if you were well-rested.
Reason #4: If you’re losing weight, getting more sleep enhances fat loss (as opposed to lean-tissue loss).
Reason #5: Women who sleep more than eight hours a night have a 72% lower incidence of breast cancer than those who regularly sleep fewer than six hours a night.
I could go on, but I think I’ve made my point! If you are taking good care of your health in every other way, don’t cheat yourself on a good night’s sleep. If you think you don’t have time to get more sleep, just think of how much more you will be able to accomplish when your body and brain are fully rested and energized. Stop thinking of sleep as a luxury and start thinking of it as an essential part of your prescription for a long and healthy life.

Is Kelp High in Sodium?
Q. On this website, it says that kelp is very high in sodium. But it also says that 10 grams (2 tablespoons) of fresh kelp has just 23 mg of sodium, or 1% or your daily needs. These two statements seem to contradict each other. Which is correct?
A. Sea vegetables tend to be higher in sodium than land vegetables–after all, they grow in sea water! Nonetheless, fresh kelp is not high in sodium. Dried seaweed will obviously be a more concentrated source of sodium. In fact, dried kelp granules are often sold as salt substitute.
Powdered kelp adds a salty, savory flavor to dishes but has just a fraction of the sodium of regular table salt. Plus, kelp is rich in other nutrients, including iodine. For more about the nutritional profile and health benefits of different types of seaweed, see my podcast “Is Seaweed Good For You?”
Why Does Nutrition Data Say Kelp is High In Sodium?
As for the contradictory information you found on NutritionData.com: As it happens, I’m fairly familiar with this site. I spent four years as Chief Nutritionist for Nutrition Data and although I’m no longer associated with them, it seems I am destined to remain the Chief Explainer for the site!
In any case, you’ve stumbled across a little weakness in the way the site reports nutrition info. The statement “This food is very high in sodium” is automatically generated for any food that contains more than 20% of the daily allowance for sodium in a 200-calorie serving. That’s all well and good for foods like potato chips or pasta, where 200 calories represents a reasonable portion. But in order to get 200 calories’ worth of kelp, you’d have to eat an entire pound of the stuff–which I doubt you’d ever do. Nonetheless, 200 calories’ worth of kelp contains about 1000 mg of sodium, or almost half the daily allowance, so it triggers the Nutrition Data “high sodium” warning.
Bottom line: Computer programs are powerful, but they sometimes lack common sense!
