How Did You Do in the Holiday Challenge?

/in /by

Did you keep track of the fruits and veggies you ate over the holiday weekend (or July 4–7 for those of you outside the U.S.)? Remember to email me your results. Some people didn’t need reminding—I have already gotten replies.

I didn’t do as well as I would have liked. Here are my lists:

  • Vegetables: tomatoes (multiple varieties), lettuce, asparagus, artichokes, cucumber, red onion, shallots, avocado, mushrooms, prickly pear, basil.
  • Fruit: oranges, grapes, cherries, apples, blueberries, raspberries, watermelon, corn on the cob, potatoes, raisins, garlic.
  • Condiments: ketchup and mustard

I know that technically tomatoes and avocado are fruit, but savory is savory in my head. I bought a couple that I haven’t used before, fresh ginger and daikon radish, but then never worked them into the menu. Both last, so I’ll have them soon. That brings my total to 24 for the weekend. I’m guessing many of you are going to exceed my attempt—and that would be great.

Saturday I’m going to begin a three-Memo arc on statistics. This applies to the study on ultra-processed food as well as the recent one on multivitamins. Even though it’s about statistics, you’ll be able to understand it. It’s important for you to have this foundation to make sense of the studies that you hear about these days.

The Holiday Challenge, Part 2

/in /by

I enjoyed the Memorial Day Challenge so much, I want to see if you can do better. I want more of you to respond this time, so I’m going to make it a little more enticing for you by handing out more prizes. This time, I’m going to reward the person who eats the most plant-based foods, but because there is an extra day, you have to exceed the past winner’s record of 28 vegetables, fruits, and herbs. I’ll also reward the person with the greatest number of different vegetables as well as the greatest number of different fruits. Just start keeping track the morning of July 4th and keep going. It was almost all women who responded last time—men, you need to step up and get in the game.

Expand your horizons and try some new veggies. Challenge yourself to eat something other than Romaine or iceberg lettuce for salads, although they certainly count. Try arugula or bok choy, or switch it up and grill some peaches or eggplant. For this challenge, corn on the cob counts as a vegetable instead of a grain. Melon, tomatoes, berries of all types, as well as bananas and apples count.

The goal is to increase your phytonutrient intake by a massive amount. Vegetables and fruit all have some nutrients you need, and summer is the easiest time to get them. You can prepare them any way you want; grill watermelon or pineapple or caramelize onions for your burgers. Creamy coleslaw also works. Cooked or raw doesn’t matter; cooking may change the form of phytonutrients but doesn’t destroy them. Remember that condiments count. Ketchup, mustard, and relish—sweet or dill—all have specific phytonutrients in them. People are becoming obsessed with pickled veggies. They count, of course.

As for how much of each food counts, use common sense. You might reasonably count the sprinkling of chives on your eggs, but adding one leaf of basil isn’t how people cook (except for maybe the tweezer-wielding chefs on TV).

Using the honor system, send me a list of everything you ate with the total fruits and veggies, the number of vegetables, and the number of fruits. I’ll offer a free six-month Insider membership or the digital Optimal Performance program to the person with the highest total in each category. Have fun, be safe, and I’ll be back next week.

Stocking up on podcasts for this holiday weekend? You can binge my podcast Straight Talk on Health, available on Spotify and other podcast sites.

I hope you all have a safe Memorial Day weekend. Here in the northern hemisphere, it’s the official kickoff of the summer season that ends with Labor Day. I alluded to a challenge, so let me lay it out for you: I want you to keep track of all the vegetables and fruit you eat beginning today.

Expand your horizons and try some new veggies. Challenge yourself to eat something other than Romaine or iceberg lettuce for salads, although they certainly count. Try arugula or bok choy, or switch it up and grill some radicchio. For this challenge, corn on the cob counts as a vegetable instead of a grain. Melon, tomatoes, berries of all types, as well as bananas and apples count. I may even try grilling avocado for the first time.

Need some ideas? Paula found this intriguing recipe online, and we’re trying it this weekend.

The goal is to increase your phytonutrient intake by a massive amount. Vegetables and fruit all have some nutrients you need, and the summer is the easiest time to get them. You can prepare them any way you want; grill watermelon or pineapple or caramelize onions for your burgers. The method doesn’t matter because cooking may change the form of phytonutrients but doesn’t destroy them. As I said in Tuesday’s Memo, condiments count. Ketchup, mustard, and relish—sweet or dill—all have specific phytonutrients in them.

Using the honor system, send me a list of everything you ate from these groups—just the names, not the amounts. For the person who gets the most, I’ll offer a free six-month Insider membership or the digital Optimal Performance program. Have fun, be safe, and I’ll be back next Tuesday.

By Any Means Necessary, Part 2

/in /by

About a year ago, I wrote about the reasons we buy food pouches for Riley. He’s six and a half, and we’re still using them, because my thinking is I’m going to get those fruits and veggies into him by any means necessary. And the battle continues.

Some evenings we have a battle royal over eating vegetables. Riley would rather eat pasta and nothing else almost every night. While he will eat pouches with just about any vegetable in it but broccoli, he won’t eat the same vegetables on his plate. The other night it was green beans. He’s eaten them before, but he’s demonstrating a rebellious streak lately. We’re not insisting he clean his plate, just eat a few green beans. Paula will wait him out; she’ll sit at the table and read a book on her Kindle until he’s done eating them.

Me? Not so much. I decided we will enhance the flavor of the green beans. Hot sauce—which I knew wouldn’t make it onto his plate. Cinnamon sugar. Whip cream. Paula thought of a savory flavor and added a sandwich sprinkle blend. The winner? Close between the cinnamon sugar and the whipped cream with ketchup, which doesn’t taste nearly as bad as you might think. Even the sandwich sprinkles got a thumbs up. All the green beans were gone in short order.

I know that’s not a traditional approach to getting kids to eat vegetables. And yet, people who would never touch an onion will eat a deep-fried one with fat imploded into it and a creamy sauce to dip it into; compared to that, I think a dusting of cinnamon sugar is just fine. My philosophy is: by any means necessary. The benefit of the vegetable outweighs the little bit of sugar or whipped cream in my opinion, especially for a kid in the 4th percentile of BMI for his age.

It’s a long holiday weekend so we’ll be back with the Memo in a week. Be safe if you’re traveling. If you’re going to spend the weekend with picnics and such, don’t forgot about eating those vegetables—by any means necessary.

By Any Means Necessary

/in /by

Riley has finished his first week of in-classroom school. He seems to have adapted quite well, which is no surprise—he is the most social child I’ve ever known and makes friends with everyone.

Much like me, he’s not much of a morning eater. Occasionally I’ll eat breakfast but for the most part, it’s not going to happen until I’ve been awake for several hours. A cup of Joe isn’t going to work for Riley, so milk and water suffice. I gave him a fruit and vegetable pouch yesterday, but he wanted to take it for a snack at school. I talked him out of it; he ate about half and saved the rest for after school.

Riley is a choosy eater: he chooses to refuse many foods that most kids eat such as apples, oranges, and bananas. Until recently, he had a strong gag reflex that was triggered by many solid foods, so we’ve continued to use pouches as a nutritional stop-gap; we watch for sales and usually pay about a dollar per pouch.

The reason I hesitated to have him take it for snack was that I wasn’t sure kids who are five still use them, and I didn’t want him to get embarrassed among his new friends. Then my health brain kicked in. He’s gotten used to eating blueberries, raspberries, and grapes in small quantities, but that’s about it. Vegetables? Other than potatoes, carrots, and Grampa’s spaghetti sauce with hidden vegetables, it’s a tough sell. But in those pouches, he eats just about everything. What’s more important: eating the fruits and vegetables in whatever form or worrying about what people think? So if he wants to take pouches to school, he will because getting those fruits and veggies into him is more important by far.

Just as serious: how are you doing with your consumption of vegetables and fruit? If you don’t get your five to ten servings, check out the pouches. They contain one or two servings of pureed vegetables and fruits, organic with no additives, and include very interesting blends; some of Riley’s faves are in the illustration. I’ve tried them and if I didn’t like vegetables and fruits, I’d use them. Cold, they’re refreshing. They’re shelf stable, so you can keep them in your desk or locker or car for convenient, healthy snacks. It sure beats making or buying a smoothie every day, and they’re a better alternative than the doughnuts in the break room or whatever you find in the vending machine.

If you’re concerned about the ecological impact, the New York Times reports, “While the pouches are not recyclable through municipal services, they can be mailed to TerraCycle at a cost of at least $93 per shipment, except for a few brands that have set up free mail-in programs with the recycling company. Pouch caps are collected in some locations by Preserve, which manufactures goods like toothbrushes and razors from recycled plastic.”

If you know you’re never going to eat kale or spinach, try a pouch. As I said, get your fruits and vegetables by any means necessary.

More Carbs? Better Choices

/in /by

Have you decided whether the extra years you may get by eating too many or too few carbohydrates are worth the effort? How about if you don’t have to make that choice at all? What if you could eat more or fewer carbs and not have to worry about it? Here are the other significant results of the study we’ve looked at this week.

When the researchers considered what people would eat to replace carbohydrates if they chose a low-carb diet, they assumed it would be animal protein such as beef, pork, lamb, and cheese as well as chicken with and without the skin. Likewise when they considered the extra carbs if people ate over 60% carbohydrates, they assumed people would choose more refined carbohydrates. They concluded correctly the additional refined carbs would contribute to metabolic disorders such as type 2 diabetes. They suggested that, based on other studies, if a low-carbohydrate diet used plant-based sources of protein, fats, and oils, there was no increase in mortality on a low-carb diet.

I’ll take it a step further and it’s something you’ve heard before: eat better. It doesn’t matter whether you want to eat a high-carbohydrate or a low-carbohydrate diet. That’s your choice. You just have to eat your vegetables and fruits first, and I’m not talking about just peas, corn, and bananas; there are hundreds of other choices to explore. You can increase the carbs in your diet without hurting your health as long as you make the right choices. Lead with vegetables and you’ll get the fiber and phytonutrients your body needs.

High carb or low carb, it all comes down to eating better. The key to living longer? Eat less. Eat better. Move more.

Broccoli: Cut It Up

/in /by

In preparing my 2018 nutrition seminar, I came across a paper on why we need to supplement our diet with a multivitamin-multimineral (I’ll be giving an overview of that paper in the next Insider Conference Call next week), and it raised a question. Quality supplements have precise amounts of specific nutrients. But what affects the nutrient content of the foods we eat, specifically vegetables? Processing? Freezing? Cooking? I picked one vegetable, broccoli, to see what I could find.

Let’s start with processing. Researchers decided to see how cutting broccoli would affect phytonutrient content. Phytonutrients are chemicals in plants that help protect the plant; when we eat the plant, they seem to help us as well. The scientists cut broccoli florets several ways: in half, into quarters, chopped it up, and kept a floret whole with just a single cut from the stem. They immediately analyzed the phytonutrient content, then stored them, and analyzed them again 24 hours later. No matter the method of cutting the broccoli, the phytonutrient content increased—yes, it increased. However, cutting the floret into quarters seemed to increase the cancer-fighting isothiocyanates and sulforaphanes the most, immediately and after storing for 24 hours.

Why did the phytonutrients increase? Because they’re designed to protect the plant from harm. Cutting means damage, and the plant is protecting itself.

What can it mean to us? Cutting up our vegetables may increase the phytonutrients that are available to us after we eat them; better yet, cut them up early and store them to give them time to marshal their forces.

Would the same thing happen with chewing? Not exactly as the enzymes in our mouth and digestive system may impede the process.

When you see the cut-up vegetables that dominate salad bars and party trays, think about eating those first before you start eating anything else. Thursday, it’s on to the effects of freezing on nutrient content.

The Bottom Line on Veggies and Carbs

/in /by

Go ahead and finish your oatmeal and drink your protein-kale smoothie—you do need those veggies. Meanwhile I’ll put the PURE study in perspective.

This is a large study that looks at the economics of food as well as the health benefits. In a separate publication, the analysis of the data focused on the cost of fruit and vegetable intake as a percentage of monthly income. They specifically collected data from low-, middle-, and high-income communities from 18 different countries. Researchers actually went to grocery markets in those countries to collect the cost data. As you might expect, the lower the income, the higher the percentage of monthly revenue spent on vegetables and fruits.

I think that explains part of the reason the second study on vegetable intake and mortality said there was no additional benefit beyond three or four servings per day: if people can’t afford more, it’s wrong to teach them that more is better if it might not be. But that doesn’t justify the headlines because the message that Americans hear is “I don’t have to eat those darn vegetables!”

Yes, you do. Here are the issues with each of the studies.

 

Do Carbs Kill?

In the first study on carbohydrate intake and mortality, researchers used a simple percentage of caloric intake in their analysis. Basically we have a math problem: if someone in a poor country eats 80% of their diet as carbohydrates from root vegetables but they only get 1,000 calories per day that’s a completely different situation from a person who eats 3,000 calories per day but 50% of their calories are from refined carbohydrates and sugars.

As I’ve said many times, while we should eat fewer refined carbohydrates, carbohydrates are not inherently bad; it is the overconsumption that’s the problem. If researchers didn’t analyze the total caloric intake from carbohydrates, protein, and fats, we don’t have the complete answer. The PURE study used a food frequency questionnaire. I’ll leave it at that because I rant too much about the FFQs.

Finally, the researchers simply jumped the gun by recommending that health education should now focus on increasing fat intake while reducing carbohydrates. All types of vegetables and fruits are carbohydrates. Because researchers did not parse out different sources of carbohydrates in their analysis, their recommendations are meaningless.

 

Don’t Bother with More Veggies?

PURE is an observational study; it cannot determine cause and effect. Also it can tell you a lot about a large group of people but nothing about an individual.

The lead researcher actually provided the perspective on vegetables and fruit during an interview: if the research shows that the benefit of eating more plant-based food is a 20% reduction in mortality, and the mortality rate of the population is just 1%, that means the reduction goes from 10 out of 1,000 to 8 out of 1,000. It’s virtually meaningless to an individual.

The researchers hesitated to tell people with very low incomes to spend more on additional servings of plant-based food if there was not a meaningful benefit. But for most of you, the cost of fruit and vegetables is not a hardship, so buy ’em and eat ’em.

 

The Bottom Line

These will not be the last headlines we hear from the PURE study because the data continues to be analyzed. One issue for me is that there’s no data from the U.S. included so the ability to generalize to the U.S. population is very limited. We lead the world in obesity and overweight and our food consumption patterns are different even from other Westernized countries.

One thing remains clear to me: we should all eat more vegetables and fruit and reduce refined carbohydrates. The recommendation never changes: eat less, eat better, move more.

PURE Headline 2: Don’t Bother with More Veggies?

/in /by

Using the same data base of subjects in the PURE Study, researchers examined the vegetable, fruit, and legume intake on total mortality, mortality, and major cardiac events such as heart attacks.

The most important finding was that higher vegetable, fruit, and legume intake was associated with a reduced risk of mortality and morbidity. Simply put, the more plant-based the diet, the better off you are from an overall health perspective.

But that’s not what the headline messages said. They focused on the part of the study that said there appeared to be no additional benefits if subjects ate more than a few servings of vegetables, fruits, and legumes. That seems to fly in the face of the “more is better” results that previous research has shown.

Have all the prior studies been wrong? Have you been eating kale for no good reason? No, and I’ll explain why the headlines are wrong on Saturday.

What are you prepared to do today?
