Controversy in Nutritional Research

 Learn about the Alkaline Diet on Facebook

  The Alkaline diet seems to have its share of “haters” for some odd reason or another. I can’t seem to understand why some researchers would have a problem with someone eating a diet of 60-80% alkaline foods everyday. And variety is encouraged as some veggies have phytonutrients that are not present in others. Even so, the “anti” alkaline diet people keep trying to find ways to raise doubts about a high plant eating style. I can imagine that there are a lot of people who are really confused about the entire health information scene as contradictory evidence is everywhere. I guess controversy should result in more research yet this just seems to muddy the waters more as different studies bring different results.

  The following article was posted on the blog at realclearscience.com. It’s hard to argue with cold hard facts yet many people still find a way. Ross Pemeroy does a good job of pointing out the shortcomings of nutritional research.

Why Everything We ‘Know’ About Diet and Nutrition Is Wrong.

Posted by Ross Pomeroy

 For decades, the federal government has been advising Americans on what to eat. Those recommendations have been subject to the shifting sands of dietary science. And have those sands ever been shifting. At first, fat and cholesterol were vilified, while sugar was mostly let off the hook. Now, fat is fine (saturated fat is still evil, though), cholesterol is back, and sugar is the new bogeyman.

Why the sizable shift? The answer may be “bad science.”

 Every five years, the Dietary Guidelines Advisory Committee, composed of nutrition and health experts from around the country, convenes to review the latest scientific and medical literature. From their learned dissection, they form the dietary guidelines.

 But according to a new editorial published in Mayo Clinic Proceedings, much of the science they review is fundamentally flawed. Unlike experiments in the hard sciences of chemistry, physics, and biology, which rely on direct observational evidence, most diet studies are based on self-reported data. Study subjects are examined for height, weight, and health, then are questioned about what they eat. Their dietary choices are subsequently linked to health outcomes — cancer, mortality, heart disease, etc.

 That’s a poor way of doing science, says Edward Archer, a research fellow with the Nutrition Obesity Research Center at the University of Alabama, and lead author of the report.

 “The assumption that human memory can provide accurate or precise reproductions of past ingestive behavior is indisputably false,” he and his co-authors write.

 Two of the largest studies on nutritional intake in the United States, the CDC’s NHANES and “What We Eat,” are based on asking subjects to recall precisely what and how much they usually eat.

 But despite all of the steps that NHANES examiners take to aid recall, such as limiting the recall period to the previous 24 hours and even offering subjects measuring guides to help them report accurate data, the information received is wildly inaccurate. An analysis conducted by Archer in 2013 found that most of the 60,000+ NHANES subjects report eating a lower amount of calories than they would physiologically need to survive, let alone to put on all the weight that Americans have in the past few decades.

 So self-reported data based on memory recall is inaccurate, but that should come as no surprise to anyone familiar with how memory works. Memory is not a recording; it’s a mental reconstruction shaped by thoughts, feelings, and everything that occurred after the event one is trying to remember. Everybody is susceptible to false memories.

 And yet, again, much of epidemiological dietary research is based on asking subjects to recall the easily altered details of what they ate! No wonder seems to point every which way!

“The American public deserves the best possible science. It is time to stop spending billions of health research dollars collecting pseudoscientific, anecdotal data that are essentially meaningless,” Archer said in a press release.

Diet studies based on self-report are conducted because they are easy. But in this case, what’s easy is not at all better. Sure, the scientific literature on nutrition is bulging with studies, but at the same time, it’s watered-down with weak, meaningless information. Perhaps that’s why nutrition has become rife with hucksterism.

“The greatest obstacle to scientific progress is not ignorance but the illusion of knowledge created by pseudoscientific data that are neither right nor wrong,” Archer writes.

 Instead of focusing on inaccurate dietary advice, Archer urges a renewed focus on physical activity as a tool for maintaining health.

 Nutrition research is awash in woo. To fix that, scientists should conduct only the most rigorous studies, preferably randomized-controlled trials, and funding agencies like the NIH and the CDC should only give grants to this sort of research.

 The motto of the Royal Society of London, the oldest scientific society in the modern world, is Nullius in Verba.

 “This phrase… is translated as “on the word of no one” or “take no one’s word for it” and suggests that scientific knowledge should be based not on authority, rhetoric, or mere words but on objective evidence,” Archer writes.

 Ironically, self-reported data directly contradicts the Royal Society’s motto. Credulous nutrition scientists are literally taking everyone at their word. This has to end.

Exercise is important for controlling blood pressure and blood sugar levels. So what we have learned here is that despite all the contradictory evidence going back and forth among the experts, the best thing that we can do is become more physically active. Exercise works wonders for people with High Blood Pressure and has the ability to help control the blood sugar of people with pre-diabetes or Type 2 diabetes. I have always said that the human body is built for movement so we must find ways to move! Early humans would spend hours each day in search of edible fruit, vegetables and gathering nuts. Chasing animals through the wild had to be a heck of a workout. Constant physical activity meant that the few sugars that were consumed were immediately burned for energy so there were probably NO obese humans prior to the development of civilization. Reverse your high blood sugar readings with a diet high in Alkaline veggies.

Alkaline Food And The Paleo Diet

“FOLLOW” on Twitter  or “LIKE” on Facebook

Eating a diet high in alkaline foods is important if you want to reduce the odds of developing diseases such as heart disease and obesity. The minerals and phytonutrients found in alkaline foods help the body to easily maintain proper pH balance and support a healthy immune system. Most people who eat a vegan diet are already on a diet high in alkaline-forming foods as the high intake of veggies and fruits make this an alkaline diet. However, there are people who still want to eat a Paleo diet of meat and/or dairy and wonder if they can make this part of an alkaline diet and the answer is YES!

The key to a successful alkaline diet is eating between 60% and 80% of your food in the form of alkaline-forming foods. This leaves plenty of room in your diet for acid-forming foods such as meat, wheat and dairy. If you want to see an alkaline/acid-forming foods chart the please go to this page. You can eat a diet of 20% to 40% acid foods such as meat and still be considered as eating healthy as long as the rest of your food intake is a wide variety of alkaline foods. Eating a Paleo diet would mean eating meat and non-starch vegetables. This means NO grains (corn is a grain). This also means NO dairy. Animals were not domesticated during Paleo times thus very little dairy product was consumed.

Eating a diet non-existent of wheat, rice, potatoes, corn or beans could really burn a lot of excess body fat if practiced for any length of time. Eating lean animal protein and fibrous vegetables is a diet many athletes eat to promote fat-burning. Being lean is associated with good health and it has been proven that excess calories may equal to the development of disease. The inflammation caused by wheat, dairy and processed fats would be reversed because these products are not allowed in the Paleo diet. All this means that your waistline will be slimmer if you eat this way!

 Spicy Kale Chips

  • 1 bunch of green kale
  • 1 TBS of coconut oil
  • 1/4 tsp cayenne pepper
  • 1/4 tsp curry powder
  • Sea salt to taste

 

  1. Pre-heat oven to 300° and spray two baking sheets with oil.

 

2.  Thoroughly wash kale and tear into bite sized pieces while discarding stems. Place in a salad spinner and dry well.

 

3.  Combine olive oil, cayenne, and curry powder into a small dishand whisk together.

 

4.  Transfer kale to a large bowl and drizzle the coconut oil mixture over it. Toss with your hands until all the leaves are evenly coated.

 

5. Spread the kale in a single layer onto the baking sheets and place in the oven for 18-20 min, turning once halfway through baking. The kale is done when it is crispy and slightly brown around the edges.

 

6.  Lightly sprinkle with salt and begin to devour.

 

Of course, you need to balance this out with a tasty acid food so how about making it a true Paleo meal by eating a few chicken wings with your kale chips! This makes for great TV watching and snacking or maybe it can be prepared for the next big game. Replace ALL of the starches in your diet with lots of non-starch alkaline foods.

Spicy Smoked Chicken Wings

Smokey sweet and spicy, these chicken wings are crispier than glazed wings. They’re also really easy to prepare – simply combine all the ingredients and toss your wings in to coat.

 

  • 1 teaspoons ground cumin
  • 1 teaspoon powdered garlic
  • 2 teaspoon powdered onion
  • 1 teaspoon dried red pepper flakes
  • 1 teaspoon hickory smoke seasoning
  • 1 teaspoon salt
  • 2 pounds chicken wing pieces
  • 2 tablespoons coconut oil

 

  1. Preheat the oven to 425 F.

 

2.  In a large bowl combine all ingredients and then toss in your chicken wings. Once coated, lie the wings in a single layer on a baking sheet.

 

3.  Bake for 20 minutes. Flip the pieces over, bake for another 20 to 25 minutes. They should be slightly crisp and golden on the outside.

 

4.  Serve hot!
