For more than four decades I’ve been involved in the dietary supplement business, from my humble beginnings working in a natural foods store to creating my own line of the highest quality supplements available on the market.

It has been a long, challenging, and educational road. And I understand—from an insider’s viewpoint—just how difficult it is to know whom you can trust when it comes to choosing the most effective dietary supplements.

People love the idea of ‘super foods,’ and I’m commonly asked my thoughts about everything from goji berries to blue-green algae. Some super foods, like chia seeds and coconut oil, are foods that I recommend. Others, like blue-green algae—sourced from a lake polluted by agricultural runoff—are supplements that I obviously do not advise taking.

But even the super foods I like and recommend don’t compare to the humble potato. The humble potato is nutrient dense, and not only is it good for you, it’s good for the health of the planet.

Potatoes have gotten a bad rap, with many people thinking that they’re fattening and devoid of nutritional value. But potatoes have a long history of nourishing humankind. In Ireland, people based their diets on nutrient rich potatoes for hundreds of years.

Over the past 30 years, gluten has become the number one villain among foods. At one time, an allergy to gluten was rarely seen. Today, almost 3 million people in the United States have celiac disease, a serious immune reaction to the protein in wheat, barley, and rye. Another 18 million people are thought to suffer from non-celiac gluten sensitivity, which causes symptoms similar to celiac disease (including diarrhea, fatigue, and nausea) but does not damage the lining of the small intestine.

In my blog on proton pump inhibitors (PPIs) a couple of weeks ago, I discussed the dangers of these drugs that are commonly prescribed for treating GERD and indigestion. Patients often ask me if there are natural alternatives to PPIs.

I recommend complete digestive support that focuses on safely alleviating symptoms and restoring digestive tract health. The goals should be to:

  • Neutralize stomach acid to relieve heartburn, acid indigestion, bloating, GERD, and upset stomach.
  • Support digestion and normal gastrointestinal (GI) health and response.
  • Support normal GI immune and inflammatory response.
  • Support normal GI tract healing, provide support and protection to the mucosal lining, enhance GI permeability health, and address leaky gut syndrome and immune dis-regulation.
  • Provide optimal support for the epithelial lining of the GI tract, esophagus, throat and mouth.
  • Support nervous system/digestive system connection and assist the gut, nervous system, and brain network.
  • Support gum and oral tissue health.

I’ve spent the past four decades researching and refining the diet that I’ve found best supports health and healing. The Eclectic Triphasic Medical System (ETMS) approach to diet is based on traditional wisdom and supported by scientific research. It is sensible, balanced, diverse, nutrient-rich, and delicious.

In my last post, I addressed the currently popular ketogenic diet, which many people have adopted for weight loss. Other people pursue the carbohydrate-restrictive, fat-laden keto diet with the hope of curing cancer. Neither of these outcomes is supported by research.

Guidelines for the ETMS Diet: An Optimal Nutrition Plan

The primary guidelines of the ETMS diet are based on a pesca-flexa-vegetarian diet, which I describe in detail here: https://www.donnieyance.com/pesca-flexa-vegetarianism

I have been involved in the health industry for four decades and in clinical practice for three decades, and have seen every possible variation of supposedly health-promoting diet come and go. Macrobiotic, raw food, fat free, vegan, and high protein diets have been touted as diets for preventing or healing from cancer, most of them offering up a confusing array of contradictory advice. The most recent diet to appear on the scene is the ketogenic (keto) diet, a high fat and low protein regime virtually devoid of carbohydrates. I would like to share my opinion on why I am not in favor of the ketogenic diet in general and the very rare and specific circumstances in which it could possibly have benefit with short-term use in people with brain cancer.

Health Consequences of Ketogenic Diet
A keto diet is high fats, moderate in protein, and extremely low in all carbohydrates (both good and bad). By restricting all (including healthy) carbohydrate consumption to a mere 20-50g per day the keto diet aims to starve the cell of body (including the brain) of glucose. When glucose stores are depleted due to starvation or extremely low carbohydrate consumption, the body goes into ketosis (this is where the name keto diet comes from). In ketosis, the liver breaks fat (and secondary protein) down into ketone bodies as a secondary fuel source for the brain. While this diet, by inducing fat breakdown via ketosis can produce impressive weight loss, this “quick fix” can also come at a cost.
