Using Nutrition to Ward Off Side Effects
Understanding the relationship between food and medicine has been of interest for centuries. The earliest medicines were derived from plants and animals. Digitalis, used in the treatment of heart conditions, is a medicine derived originally from a plant source -- foxglove. Pharmaceutical grade (pure) medications were developed to standardize both the quality and concentration of a drug in a medicine. Today Western medicine has grown reliant on pharmaceutical technology to produce drugs that will treat many conditions.
In disease treatment we try to impact biochemical pathways (how medications and foods are processed). We "push" a pathway to produce specific chemical endpoint and to affect metabolism. We can also use what is known about the way medicine and nutrients work together to improve effectiveness and allow the use of lower doses -- translating to lower healthcare costs and lower side effects.
However, not all medicines work that way. HIV medications cannot be dose adjusted based on diet. Also, in HIV disease nutrient requirements are affected by the disease itself and the interactions of multiple medications. Still, we can minimize side effects and changes in metabolism with diet and nutrient supplements. Medication effectiveness and potency is increased through improved drug absorption and tolerability and less side effects.
Many of these medicines require nutrients to improve results. For example, in the treatment of diabetes there are many medicines that may control blood sugars and prevent further complications. Proper nutritional intake to correct problems in metabolism and body composition is also necessary. Achieving nutritional health may even erase diabetes completely. However, if a patient does not follow healthful practices, the medicines do not work effectively and the disease progresses.
Some of the diseases that are impacted by the power of food include allergy and food sensitivities, cancer, endocrine disorders, gastrointestinal disease, other infectious diseases besides HIV, hormonal imbalance and neurological disorders. Specific conditions where diet composition are crucial include co-therapies for treating high cholesterol, diabetes, high blood pressure, birth defects, learning disabilities, heart disease, and even Alzheimer's disease. There also is a growing body of evidence that nutritional strategies play a direct role in disease prevention.
Consider that the human body is like a Corvette. Putting diesel fuel into the gas tank should be unthinkable. Similar to a high performance vehicle, our bodies convert food into energy. Foods that contain highly processed sugars and bad fats are "improper" fuel. Our body is unable to convert these foods into energy efficiently. Pathways are diverted to fat storage. Not only does this scenario promote obesity and obesity-related disease, but it also leaves our "gas tank" low on fuel, and we become deficient in energy and nutrients.
Studies show that the standard American diet is sub-standard in basic nutrients -- including vitamins, minerals, anti-oxidants and fiber. Diets are commonly deficient in essential and healing fats and oils, like flax, borage, evening primrose and fish oil. On the other hand, the intake of other nutrients such as simple sugars (table sugar, juices, sodas and white refined starches) and processed hydrogenated or highly saturated fats (fats that are hard at room temperature, such as chicken skin and white fat marbled in meats) is excessive.
In our medical practice we seek to improve the nutritional value of a patient's diet as an adjunct therapy to primary care. Our clinical nutritionists teach strategies to improve disease-reducing complications and medication side effects. Most notable is the impact of nutritional approaches to control diabetes, high blood pressure, high cholesterol, and gastrointestinal or stomach problems. Fatigue, hormonal imbalance and pain management also respond well to a holistic care approach.
Messages to consumers and patients are misleading. Yet the bottom line is simple -- eat wholesome food, including the proper fats and oils. Limit junk food and bad fats.
Perhaps the most important thing for our patients to do is to keep an open mind about the process. Often patients have the idea that they will never have another French fry again. They are frequently surprised by the variety of foods that we recommend including in their diets. (See table below.)
