The Link Between Nutrition and Mental Illness

Clinical psychologist Julia Rucklidge at the University of Canterbury insists that optimizing nutrition is a safe and effective treatment for mental illness. She argues that our reliance on pharmaceuticals has led us down the wrong path when it comes to mental illness.

While she notes that medications can be very effective in the short term, in the long term the side effects and decreasing efficacy over time show us that pharmaceuticals may not be the answer. Her research has shown that twice as many people with ADHD, bipolar disorder, or depression improved with the addition of high doses of micronutrients to their diet. Even post-traumatic stress disorder and psychosis can be impacted or avoided with the addition of micronutrients.

Dr. Rucklidge’s take-away message: A well-nourished body and brain is better equipped to manage stress and emotions.

Fascinating stuff. Watch it for yourself.

Why I’m Not A Fan of the Paleo Diet

I cheered when I read the recent Washington Post article dissin’ the Paleo Diet! Finally, a voice of reason and sanity to refute those who still believe that the Paleo Diet is the healthiest way to eat.HumanEvolution

While I totally agree that we did not evolve to eat refined, highly-processed, or chemically-laden foods, we didn’t really evolve to be “healthy,” either.

“Natural selection really only cares about one thing, and that’s reproductive success,” points out the author of The Story of the Human Body: Evolution, Health, and Disease, Harvard University professor of human evolutionary biology Daniel Lieberman.

Stone-age humans rarely lived many years beyond reproductive age, and I think we can all recognize that it is generally easier to feel healthier with less attention to nutrition in a young and forgiving body than with one in middle-age.

Additionally, since early humans lived in many ecosystems with many different foods available, there really was not one single “diet” available to everyone. We have survived because we are omnivores and could find sustenance from a wide range of sources. Lieberman notes that there is evidence to show that hunter-gatherers in the Middle East ate barley – a direct refutation of the premise of the Paleo recommendations of a grain-free diet.

My feeling is that the Paleo Diet is simply a re-hashing of the Atkin’s Diet, The South Beach Diet, and other low-carb diet fads from our recent past. Not only are these diets difficult to sustain over the long term, but they are simply not engineered to produce vibrant health.

My advice about the Paleo diet: If you are really looking to be healthier, skip this fad and focus on eating whole foods and avoiding chemicals and toxins.

Could Your Gut Bacteria Be Making You Anxious or Depressed?

New research from neurobiologists at Oxford University shows there could be a link between the health of your gut microbiome and your emotions. The study suggests that using probiotics to populate your gut with good bacteria together with eating enough prebiotics –carbs that nourish your bacterial population– can help lift your mental state.

Foods high in probiotics

Foods high in probiotics include yogurt, keffir, kim chee, sourkrout, and other fermented foods.

Foods high in prebiotics

Foods high in prebiotics include asparagus, onions, leeks, grains, legumes, and cruciferous vegetables such as cauliflower, broccoli, kale, kohlrabi, radish, and rutabega.

It seems the bacteria inside us might affect us more than we ever could have imagined.

Yet another checkmark against the” Paleo”-style diet as being the ultimate diet for humans.

My motto: Be wary of fad diets that advocate elimination or extreme reduction of an entire food group.

Could Bacteria Play a Role in Colon Cancer or Polyps?

A new study has found bacterial ‘bunches’ are prevalent on colon polyps and cancers. Perhaps we may be able to reduce the risk of colon cancer just by taking probiotics and prebiotics to help keep the levels of bad bacteria at bay. Plant-based digestive enzymes would likely also be helpful to reduce and inhibit biofilm formation. probioticsHere’s the whole article:

FRIDAY, Dec. 19, 2014 (HealthDay News) — Dense bunches of bacteria called  biofilms can be found on most colon polyps and cancers, a new study finds.

The researchers said these biofilms were especially prevalent on the right side of the colon. The presence of these biofilms may represent an increased likelihood of colon cancer and could offer a new way to predict a person’s risk for the disease, the researchers said.

Like tooth plaque and slime on pond stones, these biofilms may coat the mucus layer of cells lining the colon, according to background information from the study. There, the biofilms may cause inflammation and some noncancerous bowel diseases, said Dr. Cynthia Sears, professor of medicine and oncology at the Johns Hopkins University School of Medicine and Bloomberg School of Public Health.

The researchers examined healthy and cancerous tissue collected during biopsies on almost 120 people. Biofilms were present on 89 percent of tumors removed from the right colon, according to the researchers. Biofilms were found on only 12 percent of tumors removed from the left side of the colon. The reasons for the difference between the right and left side of the colon are unknown, the researchers said.

The risk of developing colon cancer may be five times higher in people with biofilms on the right side of the colon, compared to those with no biofilms, said the authors of the study. “What was so striking was that these biofilm-positive samples cluster so dramatically in the right colon. In fact, it’s virtually a universal feature of tumors that appear in that section of the colon, although we don’t understand why,” Sears said in a Hopkins news release.

It may be possible to develop a noninvasive test to detect these biofilms and predict a person’s risk of developing colon cancer. Most of these cancers develop over five to 10 years “and it’s a disease that’s curable if you diagnose it early,” Sears said.

Colonoscopies are currently the “gold standard” in detecting colon cancer. But only about 60 percent of Americans get them, according to the researchers. And colonoscopies often aren’t available in resource-poor countries, they noted.

The study was published online recently in the journal Proceedings of the National Academy of Sciences.

Substitutes for Canola Oil

Reader question: After watching your TED talk and learning more about GMOs, I’m wondering: Do we stop using canola oil entirely, or just switch to organic, non-gmo canola? I don’t fry (because I’m too lazy to clean up), but I do use canola oil in baking, as I don’t use butter or any milk products. For salad dressings, marinades and stuff like that, I use olive oil. Thanks! ~Angel A., Denver, CO

Angel, I personally advocate for avoiding canola oil entirely.

Canola oil should not be your oil of choice when cooking or baking.
I think you should stop using canola oil.

Yes, I know that canola is used in many of the recipes in my cookbook, but I have learned a lot since I first wrote the book in 2001. I used to be a fan of canola oil, but now I know better. And so should you.

Not only is 90% of our canola crop now genetically modified, but canola is not from a plant that we ate during our evolution on this planet. In fact, there is no “canola plant.” A little history of canola oil can be helpful to know:

Rapeseed oil has been used as an industrial oil to lubricate machinery for a long time because it sticks to metal. During WWII there was a high demand for industrial lubricants and Canadian rapeseed oil producers expanded to meet the demand. After the war, there was an intense effort to breed a rapeseed plant that would produce a low erucic acid rapeseed oil to sell as a cooking oil for human consumption. In 1978, they named it “Canola” to stand for Canadian oil low acid.

The rest, as they say, has been marketing genius.

In terms of replacing canola oil, we want to look for a light, flavorless oil with a high flash point so that it won’t oxidize at higher cooking temperatures and can be used for frying, should you want to. Here are some better oils to consider in place of canola:

  • Safflower oil
  • Sunflower seed oil
  • Grapeseed oil
  • Rice bran oil
  • Organic soybean oil
