Raw Liver Safety :: Soaking Seeds :: Too much Vitamin D

By Sally Fallon

Question: I am excited about eating raw foods, and have been really enjoying my raw milk (Cleopatra’s). I recently sourced some organic calves liver and have been eating it raw by swilling some small frozen chunks in my raw milk. The liver has been frozen for more than 2 weeks, but I am questioning the validity of Sally’s claim that this will kill all parasites (especially eggs and cysts which I suspect are freeze resistant). I am chomping at the bit to get back into my raw liver, but am worried about infecting myself with organ burrowing critters. Also wondering how much liver I can safely eat each day (assuming parasites are not an issue). Looking for reassurance, and perhaps some studies to support the claim. Thanks, Nick

Answer: I have been told by several experts in this field that freezing for 14 days does the trick for parasites. Also, the FDA requires that sushi fish be frozen (not sure what the time period is) to get rid of parasites–they deem it safe after a period of freezing, which is significant because raw fish can be a serious source of parasites.

Question: I read NT and there are methods for soaking nuts and seeds. But I was wondering s there a need for soaking tiny seeds? Like poppy seeds and sesame seeds? - Huiting
Answer: Hard to say–I think it depends on the seeds. Historically, Sesame seeds were usually roasted before eating. Flax seeds do not need to be soaked–they are very low in phytic acid. I don’t really know abut poppy seeds. Teff, the grain used in Ethopia, is a tiny seed. This is usually ground and then fermented to make injera bread.

Question: Our family has been taking cod liver oil daily for a year. I avoid sunscreen as much as possible to gain more Vit D and avoid chemicals. Some practitioners like Dr Mercola believe you can overdose on Vit D by taking Cod Liver Oil AS WELL AS getting plenty of sun. Cod liver oil was traditionally taken by people in northern COLD climates. Is it still necessary for us in sunny summer Australia? Can we really overdose? Does High Vit Butter Oil (which we also take) have Vit D, or only A? I am also concerned for my children who take both
and get plenty of sun. Thanks. - Mary

Answer: Chris Master John has, Vitamin D researcher, says this: “..if one is getting plenty of D from sun, one can get A and n-3’s from the other sources (fatty fish, liver, egg yolks, etc). If the dose of CLO is small (one or two servings) I wouldn’t worry about it, but, to ease her anxiety, she could have them test their 25(OH)D, and if it is in a reasonable range, they can just keep on doing what they are doing.”

  1. All very helpful information in this Q & A column! I would like to point out that hemp seed, too, is said to lack tripsyn inhibitors, phytic acid, etc. (I’m not pretending to know much about these substances.) However, I looked up traditional uses of hemp and I don’t see - maybe I missed it - that they ate much of this as a food a long time ago. Instead, any consumption was as a medicine or the resinous bracts used as an intoxicant.

    I am wondering if we should reject hemp seed as a food (it is marvellously nutritious) purely because it was never traditionally used that way…my broader question is: can something be good for us modern people without it having been known to trad. societies? My own instinct is to believe that it can be.

    You miss a significant piece of information - temperature.

    To kill parasites and their eggs the fish or meat needs to be frozen at a constant temperature of less than -20C or -4F for 7 days. You should put a thermometer in the freezer and check it at different times of the day and over a period of days as the freezer temp can vary markedly. My freezer fluctuates between -12C and -18C. At lower temperatures less time is required but at higher temperatures longer time is required. Please check the US dept agriculture or FDA website for more info. Eating raw fish and meat should not be done without sufficient information. Kind regards Abby Eagle

  3. Sally,
    I read in your NT book that tahini made from ground sesame seeds is ok because the hulls have been removed which contain significant amounts of ocalic acid, phytates and enzyme inhibitors.

    Organic tahini made from hulled, roasted sesame seeds is very expensive. What do you think of the following: soaking the seeds with salt water as you recommend for nuts - dry roasting in the oven and then grinding into butter via the Champion Juicer (w/ nut butter blank).

  4. Hi Anna May,

    I’ve been trying to find a NT way of handling sesame seeds! Can you elaborate on your methods described above? Do you soak the sesame seeds in an acid medium? Do you dry them before you roast? How do you roast them? Is this just for taste or does it break down phytates? How do you grind them? I use a coffee grinder for my flax seeds… would that be OK for the sesame seeds? To what texture do you grind them? How long do they last once roasted and ground? Do you store in the refrigerator?

    Does anyone else have any information on sesame seeds that might help me?
