A recent study published in the Journal of the American Dietetic Association found a three-fold increase in the metabolic syndrome in children eating the least amount of dietary fiber when compared to the group eating the most. There were no differences when consumption of saturated fat or cholesterol was analyzed however.

The researchers recommend focusing on increasing fiber in the diet, and not worrying so much about finding low-fat foods. That does not mean teens should fill their diets with fat-filled foods, but it does mean seeking out nutrient-dense foods high in fiber.

This makes sense to me. Most low-fat foods today are those processed foods that have been filled with sugar to make up for lack of taste that comes with low-fat options. Replacing fat with sugar in foods is what has contributed to the current obesity and diabetes epidemic this country now faces. Up to 30 percent of teen’s dietary intake comes from beverages and sugary snacks. This has to change.

But change can be tough. Joseph Carlson, the lead researcher, stated, “The trick is getting people into the groove finding the foods that they enjoy and that are convenient.”

The statistics are screaming at us from many different sources. Our diets and lifestyle have to change in order for us to see significant health improvements. This begins in childhood. I recommend that adults consume at least 35 grams of fiber daily. For children and teens, I recommend adding 5 grams to their age. So a 13 year old should eat 18 grams of fiber daily. How can you add fiber back into your diet, and the diet of your family?

The human gut is home to thousands of different bacterial species, totaling 100 trillion bacterial cells—that’s about four pounds of bacteria, or the weight of a brick. The composition of this bacterial population (also known as the gut microbiota), is currently being studied. Dr. Smith recently blogged on it.

A new study by researchers from the University of Pennsylvania, published in Science, takes the findings further. This new study found two major gut types—Bacteroides and Prevotella—based on gut bacterial population groups in 98 healthy volunteers who were asked to fill out questionnaires that assessed dietary habits. Stool samples were collected to determine their gut microbiota composition.

The researchers found a link between dietary habits and gut types. People who ate a diet high in meat and saturated fat were higher in Bacteroides bacteria, and people who had a diet high in carbohydrates had more Prevotella bacteria. Researchers then took ten volunteers and fed half of them a diet high in fat and low in fiber, and fed the other half a low-fat, high-fiber diet. By the end of ten days the bacterial populations had begun to change, but were still predominantly the same Bacteroides and Prevotella groups. This indicates that it’s possible to change the gut microbiota with diet, but it will take more than a short term change to see any major difference.

Next steps will be to replicate these findings to confirm them, and to take the studies further by looking at whether these gut types are associated with health or disease. It’s an exciting area of research, working out the details of what I have said all along—your gut is the foundation of the health of the rest of your body. It all begins in the gut.

Would you be surprised to know that eating a high-fat meal and/or high-sugar meal causes your arteries to not work in a normal manner? Let’s say we start the day with either coffee with cream/sugar and donuts, or same coffee/sugar with eggs and toast with butter/jam. And then for lunch or supper, we eat meals with high-fat meat, bread and butter, a baked potato with sour cream and butter along with an alcoholic drink (or even ice tea with sugar). Then we finish the meal with a nice dessert.

Each of these meals can cause your arteries not to function properly by the end of the meal which could last for several hours!¹ If you tend to eat this way, most of the day your arteries are constricted and not dilating normally in response to routine activities. The result, at the very least, is high blood pressure. This problem can be eliminated simply by cutting out the excess saturated fat and sugar, and adding probiotics or cultured foods high in bifidobacteria, in addition to eating plenty of vegetables throughout the day.

The above illustration of the diet-artery connection illustrates just one of the many ways to create a problem known as endothelial dysfunction, a condition that occurs when the cells lining the arteries, veins, and lymphatics don’t work properly.² There are a multitude of ways to cause the vessels to not dilate or constrict normally, and to cause the lining to leak (let’s call it leaky vessel syndrome). Endothelial dysfunction is a precursor to atherosclerosis.³ Here is a short list of endothelial dysfunction triggers:

1. Smoking, polluted air,⁴ food, and water⁵ – All of these create excess free radicals which are a major cause of endothelial dysfunction.

2. High blood sugar and/or high insulin levels – High blood sugar results in glycosylation (think of it like a sticky sugar coating) of the insulin receptor substrate, which eventually leads to an inability of protein kinase B (Akt) to increase endothelial nitric oxide synthase (eNOS) enzyme activity, resulting in low nitric oxide (NO) and poor blood vessel function.⁶

3. Microbes (bacteria, viruses, fungi and parasites), parts of microbes, and toxins made by microbes migrating from inside the intestinal lumen into the arterial, venous and lymphatic circulation – Microbes and their toxins activate white blood cells and they release bullets (anti-microbial peptides) named alpha-defensins that not only damage the microbes but the endothelial lining as well.

4. Stress – Stress increases cortisol, which can elevate blood sugar and insulin, again sugar coating receptors to result in low NO, and thus, endothelial dysfunction.

5 Aging – Aging decreases stem cells that help with repair processes, increases blood cortisol levels (see number 4), and decreases bifidobacteria levels in the colon. All of this leads to endothelial dysfunction.

6. Increased body fat, especially in abdomen – Even a modest gain of about 8 pounds (which can happen over a vacation) will cause endothelial dysfunction. “In normal-weight healthy young subjects, modest fat gain results in impaired endothelial function, even in the absence of changes in blood pressure. Endothelial function recovers after weight loss. Increased visceral (belly) rather than subcutaneous fat predicts endothelial dysfunction.”⁴

One of the mechanisms by which fat hurts the arteries is by releasing a cytokine known as resistin. Resistin has been shown to cause oxidative stress and decrease endothelial nitric oxide synthetase (eNOS) which is essential for nitric oxide (NO) production, itself essential for arterial health and function.

7. Physical inactivity – Merely by doing nothing, the process of ongoing free radical activity due to diet, stress and environment, will decrease nitric oxide (our natural vasodilator), superoxide dismutase (our own natural anti-oxidant) and citrate synthetase (the enzyme in our mitochondria involved energy production—essential to a healthy heart / blood vessel function). These natural sources of blood vessel protection return merely by walking briskly on a regular basis.⁵

8. Diabetes types 1 and 2 – Again, elevated blood sugar and either high or low insulin levels, as are seen in diabetes, will lead to endothelial dysfunction as described above.

9. Drugs which elevate or lower blood sugar and insulin – Many diabetic drugs can cause endothelial dysfunction by not maintaining steady levels of blood sugar and insulin. Insulin itself is one of the worst offenders.

10. Even children receiving second-hand smoke in a household with smokers, begin developing endothelial dysfunction at an early age.

Non-alcoholic fatty liver disease, or NAFLD, is a serious condition that causes excess fat to build up in the liver, and recently scientists discovered something interesting about its connection to sugary soft drinks.

People with NAFLD tend to drink more soft drinks than those without the disease. In fact, 80 percent of people with NAFLD were shown to drink excessive amounts of soft drinks (over 16.9 ounces per day). What’s more, those same soda drinkers were also found to live more sedentary lifestyles, eat less fiber and fewer dairy products, and consume on average more saturated fats and trans fats—all of which are components of the Standard American Diet, or SAD… talk about an appropriate acronym!

Unfortunately, cases of NAFLD are increasing, and the disease has been linked to other health problems including metabolic syndrome, diabetes, heart disease and liver disease. The scary thing is that most people with NAFLD have no symptoms, similar to people with high cholesterol or triglycerides. You may feel just fine, think you eat just fine for the most part, exercise when you can, take a multivitamin when you remember…and then all of a sudden something like NAFLD shows up and you’re completely caught off guard.

Because of this study and so many others, I can’t stress enough how important it is to be proactive when it comes to your health, especially the health of your liver—it’s your body’s detox powerhouse after all! So it may take a little time and research, but it’s worth it to really look at your diet and lifestyle and make adjustments where you can. Learn about the benefits of natural health supplements for liver support, and cut back on the soda for crying out loud! Your liver will thank you.

Notable News – I know I sound like a broken record when it comes to red meat, but  believe me, it’s really bad for you. On top of being loaded with saturated fat, studies confirm that red meat increases your risk of developing lung cancer and colorectal cancer, and now it’s being blamed for yet another health problem – prostate cancer.  I know, you were probably bought up on steaks, burgers, hotdogs and  bologna sandwiches – good all-American diet – but it’s time to rethink red meat.

Guys, listen up! Eating red meat (in addition to processed meats, which are loaded with cancer-causing nitrates) has been associated with a 9 percent increase in prostate cancer, and a 28 percent increase in advanced prostate cancer. That’s pretty scary stuff if you ask me!

Not to mention, cooking red meat to the point of charring it (you know, like when you see those black grill marks on your steak?) adds dangerous carcinogens called HCAs (short for heterocyclic amines). Makes me want to reach for that glass of red wine – at least there’s some healthy proanthocyanadins there!

Need any more reasons to avoid red meat? I don’t think so!
