1. Meat & Bowel Cancer
Could you comment on the following new UK guidelines concerning red meat?
“In the first new guidelines since 1998, Britain advised people to help prevent cancer by cutting down on steaks, hamburgers, sausages and other red meat. Government experts say people should eat no more than 500 grams (1 pound) of red meat a week, or 70 grams (2.5 ounces) every day, significantly less than it previously recommended. That works out to about one small lamb chop a day.
Scientists think people who eat a lot of meat like lamb, roast beef and ham have a higher risk of bowel cancer. In 2005, a large European study found people who ate about 160 grams (5.6 ounces) of red meat a day bumped up their bowel cancer risk by one third compared to people who ate the least meat. On average, people have about a one in 19 chance of developing bowel cancer in their lifetime.
“This doesn’t mean people have to become vegetarian, but if you’re having a steak every day, that’s probably not helping,” said Ed Yong, head of health information and evidence at Cancer Research U.K. In Britain, more than 40 percent of men eat nearly as much meat as is contained in a quarter pound hamburger every day.
Yong said there was too little data to know what might be a safe level of red meat consumption, but recommended people consider trimming their carnivorous habits. “There are no guarantees,” he said. “This is just about stacking the odds in your favor.”
Dame Sally Davies, interim chief medical officer, said red meat was part of a healthy diet but advised people who eat a lot of it to cut down. In a statement, she said the guidelines provided advice about how to prevent bowel cancer.
High levels of meat consumption have also been linked to cancers of the breast, bladder, stomach and the pancreas.
Experts suspect that haem, the pigment which gives red meat its color, damages cells in the digestive system, which may lead to cancer. Cooking meat at high temperatures, like on a barbecue, may also produce cancer-causing chemicals.
Britain’s new guidelines match advice issued by the World Cancer Research Fund several years ago. In 2007, the agency advised against eating too much processed meat like sausages or bacon and said children should never eat such products. It estimated that cutting down on red meat could save 3,800 Britons from dying of bowel cancer every year.
In 1998, UK government officials said people could safely eat as much as 90 grams (3 ounces) a day and that only people who consumed more than 140 grams (5 ounces) should worry.
Some experts said trimming too much red meat from your diet could inadvertently make people pile on the pounds.
“To cut down on meat without increasing protein from other sources will increase the obesity problem,” said Arne Astrup, a nutrition professor at the University of Copenhagen. He said people should substitute red meat with more lean sources of protein like fish rather than with more fatty foods, which tend to be more filling.
Scandinavian countries recommend people eat a slice of red meat about the size of a small pork chop every day – more than the new British guidelines allow.
In the U.S., there is no specific advice about red meat, but federal guidelines say people can eat nearly double the amount of protein – including red and lean meats, fish and eggs – recommended by Britain.”
2. Raw Vegan
I was wondering your take on the raw vegan diet. I fully agree on the vegan diet you were on being bad but on the raw vegan side of things I do not see people getting sick on a raw vegan diet that is mostly grain/dairy free.
3. Trying to make legumes legit
I was reading in “On Food and Cooking” by Harold McGee that prolonged boiling of legumes deactivates lectins and protease inhibitors. It does not go into specifics and wondered if you could shed any light on it. How much to boil? Do certain legumes respond better? What other things should one consider if boiling them stops two of the major reasons we’re to avoid legumes?
4. Coconut oil
Thanks for teaching me about the many benefits of coconut. That said, I have a few questions (and I think your listeners will benefit from hearing your answers as well).
1) I’ve read that coconut contains phytic acid. Should I be concerned about this? Does coconut meat perhaps contain more phytic acid than coconut milk and coconut oil? (If so, would you recommend that we soak or ferment coconut meat… or perhaps avoid it altogether??)
2) Do you recommend refined or unrefined coconut oil? It sounds like unrefined has more nutrients but it also has a lower smoke point. (Would you dare cook in unrefined coconut oil?)
3) I noticed that So Delicious sells a “Cultured Coconut Milk” product. Would you recommend this cultured version over regular coconut milk?
I’d love to hear some of your god-like insights.
5. Anti-depressants & Sleep
As standard: Thanks for the Podcast, has made a huge difference in my life. My mother cannot sleep without anti-depressants, I convinced her to do a no grains/legumes/dairy/nightshade paleo trial for her health problems after the success I have had so far. However, when she went off of antidepressants, she did not sleep for a week, and reverted back to having panic attacks, resulting in going right back to antidepressants. I have been catching up on the podcasts and am currently reading lights out. I’ve convinced her of how important getting enough sleep is, but however, without antidepressants she literally cannot sleep a blink. I definitely need some help, as I am very concerned. she tried melatonin, and some magnesium, but no success. Please pull out all the stops on this one, or at least try to point me to the right resources. I’ve exhausted the power of the standard google search.
6. Testing for food allergies
have read your book and been following the diet pretty well for the last 6 weeks. I have had relatively good success thus far. I am pretty sure I have a gluten intolerance as I seem to have skin or allergy issues every time it sneaks back into my diet. It also seems like I may have some issues with nuts and soy, possibly dairy. My problem is I go 3-4 weeks clean paleo but if I break, there are always multiple items leak back in so its hard to narrow down what is problematic. Also, its hard to decide if there really is a relationship between skin issues and food intolerance. What is your opinion on food sensitivity testing? I have been considering doing the blood test by ALCAT worldwide. www.alcat.com. This would give me a way to highlight multiple possible food allergies at once and I guess give some credibility to my thoughts on my food sensitivities. Is there any value to this type of blood test, or should I just refocus and try an elimination diet for another 6 weeks? Thanks for you time and all the great information.
7. Pregnancy, Paleo & CrossFit
Hello Robb! I was wondering if you could recommend some information or resources for paleo and crossfit combined with pregnancy. My current crossfit gym has never had a pregnant member and I have seen so many mixed opinions all over the web on both subjects. Do you have any suggestions or changes I should be making to both diet and exercise? Also, pre-natal vitamins – yes or no? (I’m guessing no because so many contain soy, ew.) So many more questions, but this should tide me over! Thanks!
I’m follow a pretty strict paleo diet other than I eat organic oatmeal with berries and nuts 3-4 times a week for breakfast.
When I started paleo, I was on a gluten free diet for couple months. I then added oat back to my diet and didn’t notice any negative effects, so I’ve kept eating it. Mainly because I really like oatmeal, it’s easy and fast to do in the morning, easy to store and cheap as dirt even when organic and uncontaminated by other grains.
Recent European studies suggest that even most people diagnosed with celiac disease can eat pure uncontaminated oat without any trouble. In a Finnish study that lasted five years twelve celiacs ate oat for five years while a control group was on a strict gluten-free diet. The biopsies showed no differences in the densities of CD3, IEL and IEL T cells between two groups.
What is your take on oat?
