The DASH Diet: No Passing Fad Here
Posted by Monty on 31 Dec 2011 | Tagged as: Uncategorized
When a diet claims to have been labeled the “best diet overall,” the DASH diet warrants some attention to discuss its creators, core principles, and overall merit in the scientific community dedicated to health, diet, and nutrition. The Dash diet is an acronym, short for Dietary Approaches to Stop Hypertension. Hypertension, or high blood pressure, is most commonly attributed to poor eating habits or lifestyle choices, such as smoking. Hypertension has been linked to several chronic or terminal illnesses, including kidney stones, certain types of cancer, Type II diabetes, heart disease, and stroke. It is believed that a healthy diet is critical in reducing individual risk for the conditions mentioned previously, and the Dash diet claims to provide a road map that an entire family can follow to eat healthy. According to the National Institutes of Health (NIH), the low-sodium Dash Diet is effective at lowering high blood pressure.
DASH Diet Creators:
The current incarnation of the Dash Diet is entitled the DASH Diet Action Plan. According to the cover and the author, Maria Heller, M.S., R.D., the Dash Diet Action Plan is proven to reduce high blood pressure without medication. While Maria Heller’s name is on the most recent book, the Dash for Health diet plan was designed and tested by a team of physicians, collectively with a long list of accolades. Below are their names and an abridged list of credentials:
- Tom Moore, M.D., Director, DASH for Health, author of The DASH Diet For Hypertension, Professor of Medicine, Boston Medical University
- Caroline Apovian, M.D., Associate Director, DASH for Health, Director of Nutrition and Weight Management, Boston Medical Center.
Diana Cullum-Dugan, R.D., L.D. Instructor of Aerobics - Pao-Hwa Lin, PhD, lead dietician of the original DASH diet and subsequent trials, faculty member at Duke University Medical Center.
- Megan Murphy, MPH, program manager of DASH for Health. Earned Masters Degree of Public Health from Boston University of Public Health, emphasis on encouraging people to adopt healthy diets and exercise.
Many other people remain involved in the day-to-day operations of the DASH diet, and the diet has received much testing and review based principally on its creators and their commitment to better health.
Whom is The Dash Diet is For:
The DASH Diet is designed to treat patients with hypertension or prehypertension. Because each patient responds to high blood pressure uniquely, the DASH Diet does not claim that it will eliminate the need for medication in every patient every time. Rather the DASH Diet low-sodium Action Plan provides flexible options for dieters so that some may be able to reduce their medication or stop taking blood pressure medications all together. When followed properly, the DASH diet is designed to increase the effectiveness of high blood pressure medications, reduce high cholesterol, and increase insulin sensitivity in individuals at risk for diabetes. The DASH Diet recognizes that the calorie and nutrition needs for everyone is unique. Consequently, they leave it to the dieter to choose their own calorie needs to narrow in on their specific manifestation of the DASH plan. Despite adjustments for the individual dieter, the core principles of the Dash Diet remain the same.
DASH Diet Core Principles:
Because the DASH diet was designed to reduce high blood pressure, the diet certainly focuses on reducing the intake of foods that contribute to high blood pressure, without eliminating them entirely. In every case, the DASH diet will be:
- Low in sodium (salt)
- High in fruits, vegetables, and fiber
- Allows for modest amounts of dairy, meats, and poultry
- Allows for modest portions of fats and sweets
While eliminating sodium is a great start in the effort to reduce blood pressure, it’s only half of the diet equation in the DASH diet. It’s also about what’s taken in. The DASH diet focuses on increasing the intake of key minerals such as calcium, magnesium, and potassium, each of which play a role in reducing blood pressure. The DASH diet also addresses other lifestyle choices that elevate blood pressure and put increased strain on the heart, namely excess weight, not enough exercise, smoking, and excessive alcohol, though moderate amounts of alcohol are allowed in the DASH diet eating plan.
How The DASH Diet Promotes Weight Loss:
The DASH Diet promotes weight loss by focusing on the tried and true methods of dieting that are common threads in many successful diets. The DASH diet is not a “crash” diet, meaning that the emphasis is not rapid weight loss. Nor is the DASH diet a short term diet so much as it is a long term eating plan. By following the DASH diet, a dieter should continue to lose weight until their body feels that it is at a comfortable weight. Thus, the early stages of the DASH Diet should naturally transition into a stage where the body maintains a stable weight. Assuming no food allergies, there are no food groups that need to be eliminated by the dieter, allowing for both variety and long term stability in the diet. The following are a few of the concepts that allow the DASH Diet to both reduce blood pressure and promote weight loss:
- The DASH Diet emphasizes a high intake of fruits and veggies, which are nutrient dense foods with few calories. The stomach cares more about volume than calories in determining when it’s full.
- The DASH Diet is low in refined carbohydrates, things like white sugar or starches such as are found in pasta. These two restrictions keep carbohydrate levels in check.
- The DASH Diet does not skimp on protein. Adequate protein intake when combined with a sensible exercise plan (which the DASH Diet also promotes) does two things. First, it prevents sugar crashes between meals when combined with carbohydrates, and it also prevents the muscle loss which can crash the metabolism.
DASH Diet Nutritional Goals:
The nutritional goals listed for the DASH Diet are listed for a target calorie count of 2100 calories. While the numbers will vary based on individual calorie needs, ideally the percentages (of calories) should remain the same.
Total Fat: 27%
Saturated Fat: 6%
Protein: 18%
Carbohydrates: 55%
Fiber: 30 grams
Potassium: 4700mg
Sodium: 1500mg-2300mg
Calcium: 1250mg
Magnesium: 500mg
Cholesterol: 150mg
The average American typically consumes up to 8% more fat, 3%-5% less on protein and carbohydrates, and double to triple the amount of sodium recommended.
DASH Diet Exercise Recommendations:
The DASH diet has some very broad recommendations and comments to make about exercise, recognizing that each dieter will start the DASH lifestyle at their own individual level of fitness. The following guidelines can be utilized by virtually anyone to increase the effectiveness of their exercise routine, or to begin one from the ground up.
Find something you enjoy and do it safely. Healthy enthusiasm toward exercise is necessary. Pushing your body too hard too fast is the fastest way to derail an exercise regimen.
Alternate exercise activities. Allowing muscle groups to rest every other day can prevent injury and provide variety.
Set a schedule. The DASH Diet recommends at least 30 minutes of exercise on most days of the week, though these can be brokendown into 10 minute blocks if time is short.
Partner up. An exercise partner can increase what exercises you can do safely, provide someone to be accountable with, and can also reduce the nervousness that can arise from working out in a gym full of strangers.
Reward yourself for setting and reaching goals, but don’t use food as your reward.
The DASH Diet, in Summation:
The DASH Diet, or Dietary Approaches to Stop Hypertension, attempts to steer the dieter into making changes in the short term that are extremely beneficial in the long term. Because high blood pressure is a risk factor in many chronic illnesses and can increase their severity, the DASH Diet approach is to nip the cause in the bud. The DASH Diet percentages are suitable for dieters between 1600 and 3100 calories, which means they are suitable for most. Following the DASH Diet has been shown to reduce blood pressure on its own, and even increase the effectiveness of blood pressure medications. The merits of the DASH Diet are many, including the fact that it is developed by doctors and provides a framework for healthy eating regardless of whether or not weight loss is needed by the dieter.
