The Five Most Important Dietary Tweaks

The Five Most Important Dietary Tweaks.jpeg

Generally, adherence to healthy lifestyle patterns has decreased during the last 18 years. Obesity is up, exercise is down, and the number of people eating just five servings of fruits and veggies a day dropped like a rock. And we didn't start out that great to begin with.

Only 3% of Americans at the turn of the 21st century had the following four healthy lifestyle characteristics: not smoking, not overweight, five daily servings of fruits and vegetables, and exercising a half hour a day at least five days a week. Whether people were wealthy or college-educated didn't matter; no sub-group even remotely met clinical or public health recommendations.

Where are people falling down the most? You can see in my video What Percent of Americans Lead Healthy Lifestyles?. If you look at heart disease risk factors, for example, most people don't smoke and about half are exercising. But if we look at the healthy diet score-which is based on things like drinking less than four cups of soda a week-a scale of zero to five, only about 1% of Americans score a four or five. The American Heart Association's aggressive 2020 target to improve that by 20% would bring us up to 1.2%.

Since we've known for decades that advanced coronary artery disease may be present by age 20--with atherosclerosis often even present in young children--it is particularly disturbing that healthy lifestyle choices are declining rather than improving in the U.S.

In terms of life expectancy, the U.S. is down around 27 or 28 out of the 34 OECD free-market democracies. The people of Slovenia live a year longer than citizens of the United States. Why? According to the most rigorous analysis of risk factors ever published, the number one cause of death and disability in the United States is our diet.

It's the food.

According to the Global Burden of Disease study, the worst five things about our diet are: we don't eat enough fruit, we don't eat enough nuts and seeds, we eat too much salt, too much processed meat, and not enough vegetables.

Studies that have looked at diet quality and chronic disease mortality risk found that those scoring higher (e.g. more whole plant foods), reduced the risk of dying prematurely from heart disease, cancer, and all causes of death combined. There is now an overwhelming body of clinical and epidemiological evidence illustrating the dramatic impact of a healthy lifestyle on reducing all-cause mortality and preventing chronic diseases such as coronary heart disease, stroke, diabetes, and cancer.

Why do we eat so poorly? Aren't we scared of dying from these horrible chronic diseases? It's almost as if we're eating as though our future didn't matter. And there's actually data to back that up, from a study entitled Death Row Nutrition.

The growing macabre fascination with speculating about one's ''last meal'' offers a window into one's true consumption desires when one's value of the future is discounted close to zero. In contrast to pop culture anecdotes, a group of Cornell researchers created a catalog of actual last meals-the final food requests of 247 individuals executed in the United States during a recent five-year period. Meat was the most common request. The researchers go out of their way to note that tofu never made the list, and no one asked for a vegetarian meal. In fact, if you compare the last meals to what Americans normally eat, there's not much difference.

If we continue to eat as though they were our last meals, eventually, they will be.


A few years ago I did a video called Nation's Diet in Crisis. It's sad that it doesn't seem like much has changed. How Many Meet the Simple Seven? is another video in which you can see how your own habits stack up.

For more on fruits and veggies and living longer, see Fruits and Longevity: How Many Minutes per Mouthful? Surprised that nuts made the longevity list? See Nuts May Help Prevent Death. What about legumes? See Increased Lifespan from Beans.

The reason public health professionals are so keen on measuring lifestyle characteristics is because modest improvements may have extraordinary effects. See, for example:

Didn't know the beginnings of heart disease may already be present in children? See my video Heart Disease Starts in Childhood. Think that's tragic? Check out Heart Disease May Start in the Womb. Is it too late if we've been eating poorly most of our lives? It's Never Too Late to Start Eating Healthier.

How Exactly Does Type 2 Diabetes Develop?

How Exactly Does Type 2 Diabetes Develop.jpeg

Insulin resistance is the cause of both prediabetes and type 2 diabetes. OkK, so what is the cause of insulin resistance? Insulin resistance is now accepted to be closely associated with the accumulation of fat within our muscle cells. This fat toxicity inside of our muscles is a major factor in the cause of insulin resistance and type 2 diabetes, as it interferes with the action of insulin. I've explored how fat makes our muscles insulin resistant (see What Causes Insulin Resistance?), how that fat can come from the fat we eat or the fat we wear (see The Spillover Effect Links Obesity to Diabetes), and how not all fats are the same (see Lipotoxicity: How Saturated Fat Raises Blood Sugar). It's the type of fat found predominantly in animal fats, relative to plant fats, that appears to be especially deleterious with respect to fat-induced insulin insensitivity. But this insulin resistance in our muscles starts years before diabetes is diagnosed.

In my video, Diabetes as a Disease of Fat Toxicity, you can see that insulin resistance starts over a decade before diabetes is actually diagnosed, as blood sugar levels slowly start creeping up. And then, all of the sudden, the pancreas conks out, and blood sugars skyrocket. What could underlie this relatively rapid failure of insulin secretion?

At first, the pancreas pumps out more and more insulin, trying to overcome the fat-induced insulin resistance in the muscles, and high insulin levels can lead to the accumulation of fat in the liver, called fatty liver disease. Before diagnosis of type 2 diabetes, there is a long silent scream from the liver. As fat builds up in our liver, it also becomes resistant to insulin.

Normally, the liver is constantly producing blood sugar to keep our brain alive between meals. As soon as we eat breakfast, though, the insulin released to deal with the meal normally turns off liver glucose production, which makes sense since we don't need it anymore. But when our liver is filled with fat, it becomes insulin resistant like our muscles, and doesn't respond to the breakfast signal; it keeps pumping out blood sugar all day long on top of whatever we eat. Then the pancreas pumps out even more insulin to deal with the high sugars, and our liver gets fatter and fatter. That's one of the twin vicious cycles of diabetes. Fatty muscles, in the context of too many calories, leads to a fatty liver, which leads to an even fattier liver. This is all still before we have diabetes.

Fatty liver can be deadly. The liver starts trying to offload the fat by dumping it back into the bloodstream in the form of something called VLDL, and that starts building up in the cells in the pancreas that produce the insulin in the first place. Now we know how diabetes develops: fatty muscles lead to a fatty liver, which leads to a fatty pancreas. It is now clear that type 2 diabetes is a condition of excess fat inside our organs, whether we're obese or not.

The only thing that was keeping us from diabetes-unchecked skyrocketing blood sugars-is that the pancreas was working overtime pumping out extra insulin to overcome insulin resistance. But as the so-called islet or Beta cells in the pancreas are killed off by the fatty buildup, insulin production starts to fail, and we're left with the worst of both worlds: insulin resistance combined with a failing pancreas. Unable to then overcome the resistance, blood sugar levels go up and up, and boom: type 2 diabetes.

This has implications for cancer as well. Obesity leads to insulin resistance and our blood sugars start to go up, so our pancreas starts pumping out more insulin to try to force more sugar into our muscles, and eventually the fat spills over into the pancreas, killing off the insulin-producing cells. Then we develop diabetes, in which case we may have to start injecting insulin at high levels to overcome the insulin-resistance, and these high insulin levels promote cancer. That's one of the reasons we think obese women get more breast cancer. It all traces back to fat getting into our muscle cells, causing insulin resistance: fat from our stomach (obesity) or fat going into our stomach (saturated fats in our diet).

Now it should make sense why the American Diabetes Association recommends reduced intake of dietary fat as a strategy for reducing the risk for developing diabetes.


The reason I'm going into all this detail is that I'm hoping to empower both those suffering from the disease and those treating sufferers so as to better understand dietary interventions to prevent and treat the epidemic.

Can You Eat Too Much Fruit?

Can You Eat Too Much Fruit?.jpeg

In my video If Fructose is Bad, What About Fruit?, I explored how adding berries to our meals can actually blunt the detrimental effects of high glycemic foods, but how many berries? The purpose of one study out of Finland was to determine the minimum level of blueberry consumption at which a consumer may realistically expect to receive antioxidant benefits after eating blueberries with a sugary breakfast cereal. If we eat a bowl of corn flakes with no berries, within two hours, so many free radicals are created that it puts us into oxidative debt. The antioxidant power of our bloodstream drops below where we started from before breakfast, as the antioxidants in our bodies get used up dealing with such a crappy breakfast. As you can see in How Much Fruit is Too Much? video, a quarter cup of blueberries didn't seem to help much, but a half cup of blueberries did.

What about fruit for diabetics? Most guidelines recommend eating a diet with a high intake of fiber-rich food, including fruit, because they're so healthy--antioxidants, anti-inflammatory, improving artery function, and reducing cancer risk. However, some health professionals have concerns about the sugar content of fruit and therefore recommend restricting the fruit intake. So let's put it to the test! In a study from Denmark, diabetics were randomized into two groups: one told to eat at least two pieces of fruit a day, and the other told at most, two fruits a day. The reduce fruit group indeed reduce their fruit consumption, but it had no effect on the control of their diabetes or weight, and so, the researchers concluded, the intake of fruit should not be restricted in patients with type 2 diabetes. An emerging literature has shown that low-dose fructose may actually benefit blood sugar control. Having a piece of fruit with each meal would be expected to lower, not raise the blood sugar response.

The threshold for toxicity of fructose may be around 50 grams. The problem is that's the current average adult fructose consumption. So, the levels of half of all adults are likely above the threshold for fructose toxicity, and adolescents currently average 75. Is that limit for added sugars or for all fructose? If we don't want more than 50 and there's about ten in a piece of fruit, should we not eat more than five fruit a day? Quoting from the Harvard Health Letter, "the nutritional problems of fructose and sugar come when they are added to foods. Fruit, on the other hand, is beneficial in almost any amount." What do they mean almost? Can we eat ten fruit a day? How about twenty fruit a day?

It's actually been put to the test.

Seventeen people were made to eat 20 servings a day of fruit. Despite the extraordinarily high fructose content of this diet, presumably about 200 g/d--eight cans of soda worth, the investigators reported no adverse effects (and possible benefit actually) for body weight, blood pressure, and insulin and lipid levels after three to six months. More recently, Jenkins and colleagues put people on about a 20 servings of fruit a day diet for a few weeks and found no adverse effects on weight or blood pressure or triglycerides, and an astounding 38 point drop in LDL cholesterol.

There was one side effect, though. Given the 44 servings of vegetables they had on top of all that fruit, they recorded the largest bowl movements apparently ever documented in a dietary intervention.


Cutting down on sugary foods may be easier said than done (see Are Sugary Foods Addictive?) but it's worth it. For more on the dangers of high levels of fructose in added sugars, see How Much Added Sugar Is Too Much?.

What's that about being in oxidative debt? See my three part series on how to pull yourself out of the red:

Ironically, fat may be more of a problem when it comes to diabetes than sugar, see:

Benefits of Oatmeal for Fatty Liver Disease

Benefits of Oatmeal for Fatty Liver Disease.jpeg

If oatmeal is so powerful that it can clear up some of the ravages of chemotherapy just applied to the skin (see my video Oatmeal Lotion for Chemotherapy-Induced Rash), what might it do if we actually ate it? Oats are reported to possess varied drug-like activities like lowering blood cholesterol and blood sugar, boosting our immune system, anticancer, antioxidant, and anti-atherosclerosis activites, in addition to being a topical anti-inflammatory, and reprtedly may also be useful in controlling childhood asthma and body weight.

Whole-grain intake in general is associated with lower risk of type 2 diabetes, cardiovascular disease, and weight gain, as shown in my video Can Oatmeal Help Fatty Liver Disease?. All of the cohort studies on type 2 diabetes and heart disease show whole grain intake is associated with lower risk.

Researchers have observed the same for obesity--consistently less weight gain for those who consumed a few servings of whole grains every day. All the forward-looking population studies demonstrate that a higher intake of whole grains is associated with lower body mass index and body weight gain. However, these results do not clarify whether whole grain consumption is simply a marker of a healthier lifestyle or a factor favoring lower body weight.

For example, high whole grain consumers--those who eat whole wheat, brown rice, and oatmeal for breakfast--tend to be more physically active, smoke less, and consume more fruit, vegetables, and dietary fiber than those that instead reach for fruit loops. Statistically, one can control these factors, effectively comparing nonsmokers to nonsmokers with similar exercise and diet as most of the studies did, and they still found whole grains to be protective via a variety of mechanisms.

For example, in terms of helping with weight control, the soluble fiber of oatmeal forms a gel in the stomach, delaying stomach emptying, making one feel full for a longer period. It seems plausible that whole grain intake does indeed offer direct benefits, but only results of randomized controlled intervention studies can provide direct evidence of cause and effect. In other words, the evidence is clear that oatmeal consumers have lower rates of disease, but that's not the same as proving that if we start eating more oatmeal, our risk will drop. To know that, we need an interventional trial, ideally a blinded study where you give half the people oatmeal, and the other half fake placebo oatmeal that looks and tastes like oatmeal, to see if it actually works. And that's what we finally got--a double-blinded randomized trial of overweight and obese men and women. Almost 90% of the real oatmeal-treated subjects had reduced body weight, compared to no weight loss in the control group. They saw a slimmer waist on average, a 20 point drop in cholesterol, and an improvement in liver function.

Nonalcoholic fatty liver disease, meaning a fatty liver caused by excess food rather than excess drink, is now the most common cause of liver disease in the United States, and can lead in rare cases to cirrhosis of the liver, cancer of the liver, and death. Theoretically, whole grains could help prevent and treat fatty liver disease, but this is the first time it had been put to the test. A follow-up study in 2014 confirmed these findings of a protective role of whole grains, but refined grains was associated with increased risk. So one would not expect to get such wonderful results from wonder bread.

How can you make your oatmeal even healthier? See Antioxidants in a Pinch.

Whole Grains May Work As Well As Drugs for hypertension, but refined grain intake may linked with high blood pressure and diseases like diabetes. But If White Rice is Linked to Diabetes, What About China?.

Does Oatmeal Lotion Work?

Does Oatmeal Lotion Work?.jpeg

A review in the Journal of Drugs in Dermatology notes oatmeal has been used for centuries as a topical soothing agent on the skin to relieve itch and irritation in dermatology. Of course, that was coming from Johnson & Johnson, which sells a brand of oatmeal lotion. But if it helps with dry skin or a bug bite, I can imagine it having some soothing quality. One study out of Georgetown University, though, shocked me.

There's a class of chemo drugs, like Cetuximab, that can cause an awful rash. Various treatments have been tried and failed. There was no clear preventive or curative treatment for this eruption, until this remarkable study, which you can see in my Oatmeal Lotion for Chemotherapy-Induced Rash video.

The researchers had heard about a study where human skin fragments from plastic surgery were subjected to an inflammatory chemical, and adding an oatmeal extract appeared to help. Of the ten patients with chemo rashes who the researchers were able to get to try some oatmeal lotion, six had a complete response, and four a partial response, giving an overall oatmeal response rate of 100%.

Doctors wrote in from around the world. Significant improvement in all patients seemed too good to be true, but out of desperation they tried it and got the same astonishing results. Oatmeal--a simple topical agent producing such spectacular benefit where more complex therapies have failed. In an age when ever more expensive treatments are consistently being championed, it would be a great pity if this inexpensive, natural approach to relieving distressing symptoms were to be overlooked.

Ironically, two of the cancer cell lines found resistant in vitro to this type of chemotherapy were found to be sensitive to avenanthramides, which are unique phytonutrients found in oats, suggesting that people should be applying oatmeal to their insides as well.

Normally I wouldn't make a whole video for such a rare use, but I was so impressed with the results I figured that even if I could help one person in this situation it would be worth it. Reminds me of my videos Treating Gorlin Syndrome With Green Tea and Topical Application of Turmeric Curcumin for Cancer.

If oatmeal is so powerful that it can clear up some of the ravages of chemotherapy just applied to the skin, what might it do if we actually ate it? That's the subject of my video Can Oatmeal Help Fatty Liver Disease?.

Cetuximab is often given for metastatic colorectal cancer. Better to try to prevent the disease in the first place:

Why Is Milk Consumption Associated with More Bone Fractures?

Why Is Milk Consumption Associated with More Bone Fractures?.jpg

Milk is touted to build strong bones, but a compilation of all the best studies found no association between milk consumption and hip fracture risk, so drinking milk as an adult might not help bones, but what about in adolescence? Harvard researchers decided to put it to the test.

Studies have shown that greater milk consumption during childhood and adolescence contributes to peak bone mass, and is therefore expected to help avoid osteoporosis and bone fractures in later life. But that's not what researchers have found (as you can see in my video Is Milk Good for Our Bones?). Milk consumption during teenage years was not associated with a lower risk of hip fracture, and if anything, milk consumption was associated with a borderline increase in fracture risk in men.

It appears that the extra boost in total body bone mineral density from getting extra calcium is lost within a few years; even if you keep the calcium supplementation up. This suggests a partial explanation for the long-standing enigma that hip fracture rates are highest in populations with the greatest milk consumption. This may be an explanation for why they're not lower, but why would they be higher?

This enigma irked a Swedish research team, puzzled because studies again and again had shown a tendency of a higher risk of fracture with a higher intake of milk. Well, there is a rare birth defect called galactosemia, where babies are born without the enzymes needed to detoxify the galactose found in milk, so they end up with elevated levels of galactose in their blood, which can causes bone loss even as kids. So maybe, the Swedish researchers figured, even in normal people that can detoxify the stuff, it might not be good for the bones to be drinking it every day.

And galactose doesn't just hurt the bones. Galactose is what scientists use to cause premature aging in lab animals--it can shorten their lifespan, cause oxidative stress, inflammation, and brain degeneration--just with the equivalent of like one to two glasses of milk's worth of galactose a day. We're not rats, though. But given the high amount of galactose in milk, recommendations to increase milk intake for prevention of fractures could be a conceivable contradiction. So, the researchers decided to put it to the test, looking at milk intake and mortality as well as fracture risk to test their theory.

A hundred thousand men and women were followed for up to 20 years. Researchers found that milk-drinking women had higher rates of death, more heart disease, and significantly more cancer for each glass of milk. Three glasses a day was associated with nearly twice the risk of premature death, and they had significantly more bone and hip fractures. More milk, more fractures.

Men in a separate study also had a higher rate of death with higher milk consumption, but at least they didn't have higher fracture rates. So, the researchers found a dose dependent higher rate of both mortality and fracture in women, and a higher rate of mortality in men with milk intake, but the opposite for other dairy products like soured milk and yogurt, which would go along with the galactose theory, since bacteria can ferment away some of the lactose. To prove it though, we need a randomized controlled trial to examine the effect of milk intake on mortality and fractures. As the accompanying editorial pointed out, we better find this out soon since milk consumption is on the rise around the world.

What can we do for our bones, then? Weight-bearing exercise such as jumping, weight-lifting, and walking with a weighted vest or backpack may help, along with getting enough calcium (Alkaline Diets, Animal Protein, & Calcium Loss) and vitamin D (Resolving the Vitamin D-Bate). Eating beans (Phytates for the Prevention of Osteoporosis) and avoiding phosphate additives (Phosphate Additives in Meat Purge and Cola) may also help.

Maybe the galactose angle can help explain the findings on prostate cancer (Prostate Cancer and Organic Milk vs. Almond Milk) and Parkinson's disease (Preventing Parkinson's Disease With Diet).

Galactose is a milk sugar. There's also concern about milk proteins (see my casomorphin series) and fats (The Saturated Fat Studies: Buttering Up the Public and Trans Fat in Meat and Dairy) as well as the hormones (Dairy Estrogen and Male Fertility, Estrogen in Meat, Dairy, and Eggs and Why Do Vegan Women Have 5x Fewer Twins?).

Milk might also play a role in diabetes (Does Casein in Milk Trigger Type 1 Diabetes, Does Bovine Insulin in Milk Trigger Type 1 Diabetes?) and breast cancer (Is Bovine Leukemia in Milk Infectious?, The Role of Bovine Leukemia Virus in Breast Cancer, and Industry Response to Bovine Leukemia Virus in Breast Cancer).
