Three Ways to Really Reduce Your Cancer Risk

/in /by

In the last Memo before Spring Break, I said I’d cover ways to reduce your risk of getting cancer that really work. Every cancer website has lists, ranging from 10 to 15 recommendations. I’m going to give you my top three ways to reduce the risk of cancer of the items you can control. You can’t control your age or your genetic risk factors, but there are many elements of your health you can control if you work at them.

I’m not including smoking cigarettes or other tobacco products. That’s a no-brainer and shouldn’t even be mentioned, because no one should smoke. (I’m not saying that from my perch on Mount Olympus; I smoked when I was young and foolish, and quitting was one of the best decisions I ever made.)

Dr. Chet’s Top Three Ways to Prevent Cancer

  1. Eat more vegetables and fruits every day and the wider the variety, the better. They don’t have to be organically farmed; you just have to eat eight to ten servings per day. That seems like a lot, and I’m not perfect at it, but you get a new chance every day. Here’s a tip: weigh your produce instead of measuring it. Find out what constitutes a serving in grams or ounces. You may find out that a large banana is actually two servings. Do supplements matter? Yes, but the important point is to eat the fruits and veggies first, then add a multivitamin as backup.
  2. Exercise for 30 to 45 minutes per day. The fitter you are, the lower your risk of cancer. It doesn’t all have to be aerobic; yoga and strength training count as well.
  3. Reduce your weight until you achieve as close to a normal BMI (under 25) as you can; you’ll find all the info you need in the Body Mass Index article on the Health Info page at drchet.com, including how to adjust your target for your body type. We talked about caloric restriction in February, and that’s a way to slowly reduce your weight. My theory is that the older you are, the more movement matters, so if you are doing well at Numbers 1 and 2, you’re well on your way to accomplishing Number 3.

Those may sound very familiar: Eat less. Eat better. Move more. The reason these are my top three is that they reduce inflammation in different ways.

On Thursday, I’m going to cover a study on the relationship between a test for inflammation and cancer.

The Supplementation Sweet Spot, Part Two

/in /by

We’ve got the beginning of our sweet spot for supplementation started with a multivitamin-multimineral and probiotics; today I’ll finish it up with two more—depending.

Omega-3 Fatty Acids

Recommendations on the type of omega-3s seem to be in flux with disagreements over docosahexaenoic acid (DHA). The cause for concern seems to be the potential relationship between DHA and atrial fibrillation. I’m still not satisfied as to the relevancy of the risk in the general population with one exception: those people who’ve had myocardial infarctions (heart attacks) that resulted in the loss of heart muscle. For now, those people may want to be cautious. My research continues and when I have an answer, so will you.

Unless you regularly eat servings of cold-water fish two or three times a week, part of your foundation supplementation should be 1–3 grams of EPA, DHA, or the plant-sourced alpha linoleic acid (ALA), or a combination of all three. You can pick any body system, and omega-3s are most likely beneficial. This is especially true of the cardiovascular and nervous systems.

Vitamin D

The final foundation supplement that makes up our sweet spot is vitamin D but with a catch. Instead of taking massive amounts of vitamin D, the best way to determine whether you need to supplement with vitamin D is to get your blood levels checked via a 25 hydroxyvitamin D (25(OH)D) blood test. If you’re low in vitamin D, below 30 ng/mL, add more vitamin D to your supplements in 50 mcg (2,000 IU) increments until your blood level reaches 40–60 ng/mL. Obviously, you need to see your doctor for the test, but you should be seeing your doctor regularly anyway.

Depending on where you live, sunlight will help you maintain healthy vitamin D levels with about 15 minutes exposure per day. However, in Northern areas such as here in Grand Rapids, that only happens about half the year, so we make sure to take our vitamin D supplement and bump it up a little in winter.

More

Vitamin D has become controversial with the current COVID-19 outbreak. Vitamin D will not prevent you from catching COVID-19; it will help reduce the severity of symptoms. But megadosing on vitamin D can have consequences that can result in bone loss. That’s why basing your intake on a blood test is the right way to go.

The Bottom Line

There you have the sweet spot for foundation supplements that all of us need, regardless of the quality of our diet. What about all those other supplements out there? Fine tuning supplementation to meet your personal needs is where supplements get complicated and need to be personalized. With the billions of dollars spent on supplements every year, if everyone began with the sweet spot of foundation nutrients, everyone would be better off, just like the sweet spots for diet and exercise.

If you want to know more about the science behind these supplements as well as how to assess a quality manufacturer, get a digital copy of Supplementing Your Diet; if you want to pass along the information to others, get a 5-pack of CDs at reduced prices. They’re all on sale at 25% off, and that’s in addition to Member and Insider discounts.

Identifying the Supplementation Sweet Spot

/in /by

I believe everyone should add a foundation of supplements to their diet, but there’s no reason to take supplements you don’t need. The last two weeks, I’ve written about the sweet spot for nutrition and exercise as I see it, so it just seems logical to do the same thing for dietary supplements. While supplementation can be very complex, there’s a foundation where we all begin. To me, that’s the sweet spot.

It all begins with a multivitamin-multimineral. With the gaps we have in our diet and with research confirming the gaps, that’s where we should start, but how to choose? Your ideal daily multivitamin-multimineral would have at least the recommended dietary allowance (RDA) for all the major vitamins and minerals. It should also have a blend of dehydrated plant material to provide the phytonutrients we’d get in plants if we ate them. That’s it. Too many brands on the market throw in herbs for men’s health or women’s health. Not everyone needs them, so why put them in a foundation supplement?

The second nutrient is actually not a nutrient; it’s probiotics. If we don’t eat enough raw or fermented foods, we’re not adding to our microbiome; adding a probiotic supplement will help build a stronger, more effective microbiome. Does the number of strains matter? No, but it’s better with strains shown by research to be beneficial. Do the colony forming units (CFUs) matter? Again, no. What does matter is whether it contains a prebiotic or not, typically a fiber such as inulin. Because our diets are poor in this food source, purchase one that contains prebiotics.

Those two supplements are the foundation of nutrition for people of every age and condition; there are two more that most people probably need, and we’ll talk about those on Saturday. If you’re interested in more of the science behind my choices, pick up a copy of Supplementing Your Diet as either a download for yourself or the CDs to share with others. They’re all on sale at 25% off, and that’s in addition to Member and Insider discounts.

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.

Phytonutrients: Diet or Supplements?

/in /by

The study that we looked at this week demonstrated that flavonoid intake is related to socioeconomic status. It also demonstrated that most of that difference comes from the consumption of tea. All well and good.

What stood out to me was the lack of phytonutrient intake. While there were some small differences in the other flavonoids besides flavan-3-ols, the total intake of flavonoids was low. Even though we’re talking about just one class of phytonutrients, the total flavonoid intake minus the flavonoids from tea was about 140 milligrams per day. That’s reflective of a poor diet that does not include as many sources of phytonutrients as it should: not enough vegetables, fruit, beans, nuts, and others. And it hasn’t changed in the six years of the study. Most people still don’t eat enough plant-based foods to do themselves any good.

Supplements: An Insurance Plan

The study demonstrated the need for the regular use of supplements containing plant concentrates. A plant concentrate is the plant or its fruit or its root or its leaves, minus the water and the fiber. It should also have been harvested at the peak of nutrition, not the peak of flavor and taste. The plant concentrates contain all the phytonutrients that are contained within the plant, and that includes not only the flavonoids that were the subject of this study, but all of the other types of phytonutrients that we need on a regular basis.

The plant concentrates may be found in multivitamin-minerals, as part of a fruit-and-vegetable concentration, or maybe even as a stand-alone. We’re not talking about treating diseases with these supplements; we’re talking about getting the nutrition that you’re supposed to be getting from the foods that you eat (but you’re not). To me, this study pretty much proves that everyone needs to take supplements with plant concentrates every day. They provide good backup while you work on improving your diet.

The Bottom Line

If you want the best chance at preventing degenerative diseases, you need optimal nutrition. That starts with what you eat, including all those phytonutrient-containing vegetables, fruits, beans, grains, and aromatic herbs used to season your food. As a backup, take supplements that contain plant concentrates to complement your diet. It’s not either/or; it’s using them both to get to better health.

Paula and I will be taking some time off to work on more jobs around the house. We’ll be back after a short break.

You’re Invited to a Live Dr. Chet Seminar in Atlanta!

/in /by

The next stop on the Dr. Chet tour is going to be in Atlanta, GA, to talk about Nutrition for the 21st Century.

I’ll start with the most important question: what’s the best diet? The keto craze is in full swing, with Paleo right behind. The opposite side is going vegan, an all plant-based diet. What’s best for weight loss? For more energy? For weight maintenance? I’ll let you know the pros and cons of each approach so you can make the right choice for you.

Second, no matter which diet you choose to follow, will you get adequate nutrients? No matter how healthy the diet, there will always be gaps because of the way our food is grown and processed. This time around, it’s not just getting the right nutrients for your body but also your microbiome, the microbes in your digestive system that are critical to your immune system. They require healthier choices as well. I’ll cover the basic nutritional supplements for adults and children to lay a good foundation.

How do you decide on a quality manufacturer? There are new companies being started every day, and I’ll give you specific criteria you can use to evaluate supplement manufacturers. If you’re going to put supplements in your body, you want to be certain they’re safe and effective. I’ll let you know how to do that.

Next, there are some conditions that may be the result of a lack of adequate nutrients. Supplements don’t cure diseases, but the right nutrition may help your body help itself. I’ll cover some common conditions.

I’ll also have time to answer your questions. The goal is to provide you with enough information for you to make healthy choices every day. Please join me to get the latest information to do exactly that.

Who should attend? People who find themselves confused by the nutrition information available; one day something’s good, the next day it’s bad. I’ll clarify that for you. If you’re concerned about your personal health or that of your family, or you’re a business owner who wants to understand supplementation and diet better, you should be there. Everyone will walk away with something that will help them make healthier choices.

News on Food as Medicine

/in /by

As a conventional medical journal and one of the leading medical journals in the world, The Journal of the American Medical Association doesn’t often publish reviews of the impact of food on health. However, a recent edition of the Journal included a summary of three such studies, and that’s the topic for this week.

The first study examined whether mushrooms, which are full of vitamins, minerals, and phytonutrients, decrease the risk of cardiovascular disease (CVD) or type 2 diabetes (T2D). The researchers re-analyzed the data from the Nurses’ Health Study and the Health Professionals Follow-up Study. When they compared more than five servings of mushrooms per day with less than one serving per day, they found no differences in the rate of symptoms or markers associated with CVD or T2D. One interesting note was that if mushrooms were substituted for meat, there was a decreased risk of T2D.

This is one of the first studies to acknowledge the problems with nutrition data in these types of studies. The data on mushrooms were only collected at the beginning of the studies; that doesn’t allow for comparisons over time. Further, the questionnaire didn’t allow for data on a variety of types of mushrooms. The best observation at this point is that we don’t know whether mushrooms or specific types of mushrooms are beneficial for reducing the risk of disease until more research is done.

We do know they’re good for you, so enjoy your mushrooms; sautéed mushrooms are a great addition to many dishes. Here’s another way to enjoy mushrooms: Creamy Mushroom Soup from the Health Info page at drchet.com. Check out the other recipes while you’re there.

We’ll look at another study on Thursday.

The Command Center

/in /by

We’re going to finish this month’s look at living life instead of just being alive by talking about brain health. The brain is the command center of the body, telling it what to do 24/7 without you having to think about it. Be honest: when was the last time you consciously told your heart to beat? It also handles conscious requests from you. Probably the most important part of our brain is our ability to think and recall memories.

In the past 10 to 15 years, a lot has been written about how to keep our brains healthy. For all we think we know, we really don’t know all that much, but there are three things that we need to do. I’ve already talked enough about exercise; what was good for the heart, muscles, joints, and balance is also good for the brain. But another type of exercise involves using the brain, such as reading, doing puzzles, listening to music, and learning new skills. For more on this topic, see How to Have a Healthy Brain.

Second, what we eat can impact brain health, as well as what we shouldn’t eat. This will come as no surprise: your diet should start with vegetables, fruits, whole grains, beans, and nuts. Whole grains are good as are quality oils such as olive oil and flaxseed oil. What we should avoid are overly processed foods, especially limiting refined carbohydrates and sugars.

Hand in glove with that, the majority of us need to eat less. Eating too much not only exposes us to usually highly processed foods, it contributes to being overweight and type 2 diabetes. Both can contribute to poor brain function over time.

We’ll finish this month’s look at living every day on Thursday.

Can Fasting Reduce Inflammation?

/in /by

In this Memo, I’ll review the third paper from the recent journal Cell on fasting and summarize what this all may mean for the use of intermittent fasting.

Researchers used both mice and humans as subjects in a series of studies. The objective was to examine how the immune system responded to a fasting protocol. For the study in humans, the subjects fasted for 19 hours after eating, with blood samples taken before and after the fast. In the mice, a variety of protocols were used. The most common was mice were fed for a short time before food was withheld for the remainder of 24 hours.

In mice and humans, circulating monocytes were reduced. This was important because they were pro-inflammatory in nature; thus inflammation decreased in response to the fasting protocol. In some of the studies, this reduction was maintained even with exposure to pathogens. That means the immune response was not compromised even in animals with induced autoimmune diseases.

Fasting Protocols

Three different studies used at least three different approaches to fasting. In the first study, food was withheld completely for 36 hours. In some phases of the second study, calories were reduced by 50% although the vitamins, minerals, and protein were maintained at normal levels. The final study used a fasting protocol we’re most familiar with: eat within a few hours and liquids only the remainder of the day.

The results were similar in sustaining and perhaps improving the immune system of the animals when placed under pathogenic stress. The only issue is what form of dietary restriction worked best? You can’t ask mice how they felt; you can only check immune system markers. In one of the approaches, the skin of the mice was injured at different times of continued fasting. The healing ability continued until the fast went beyond 48 hours; after that wound-healing was impaired.

The Bottom Line

These studies haven’t changed my approach to fasting. If you’re going to fast to rejuvenate your immune system, don’t play games. Reduce caloric intake to 500 to 800 calories per day for two to three days; those studies show the best benefit. Be sure to select small quantities of the healthiest foods.

Fasting is not abstinence. The current approaches to intermittent fasting are really intermittent abstinence. The idea is to abstain from food completely for 12 to 18 hours while still drinking liquids. That may not be possible for everyone. Some medications have to be taken in relation to food intake. Pre-diabetics and type 2 diabetics should still monitor blood sugar, especially if exercising during the fasting times. The current intermittent fasting approach is more about controlling when you eat than anything else, and that’s something you should do anyway.

I believe in fasting. That’s why I wrote Real-Life Detox—so you could do it right and gain the most benefit. The critical thing is to find a way to eat that you can sustain for the rest of your life, and that includes occasional fasts.

Eat less. Eat better. Move more. That’s always the goal.
