I'm casein intolerant and heavy cream doesn't bother me.

And here an excerpt from the page, "What am I reacting to?",

http://failsafediet.wordpress.com/the-rpah-elimination-diet-failsafe/quick-reference-what-am-i-reacting-to/

Milk and Yoghurt

Casein: opioid-like peptides (bioavailability is increased by lactobaccillus fermentation making yoghurt reactions worse than milk) Multiple immunological compounds (hormones, anti-microbial factors, immune development factors, tolerance/priming factors) Insulin-like growth factor I (IGF-1) (particularly in rBGH-treated cows, IGF-1 is resistant to pasteurisation and bioavailability may be increased by pasteurisation, though IGF-1 is undetectable after heating to 121°C for 5 minutes, at which point the proteins become denatured)

Lactose (lower amounts in yoghurt, absent from sour tasting yoghurt)

Melatonin (a relatively harmless amine that aides sleep, particularly found in milk from cows milked before dawn)

Amines, particularly tyramine (trace amounts, usually yoghurt only)

? Lectins (trace amounts, from the cow's diet, lectin super-responders only)

? Salicylates and salicylate-like polyphenols (trace amounts, from the cow's diet, salicylate super-responders only)

? Arachidonic acid (super-responders only)

? Disinfectant used to wash out milk tanks (trace amounts, potassium iodide, chlorine and others, super-responders only)

? Calcium (excitatory, causes glutamate release, super-responders only)

Do you find milk addictive? If so, assume an opioid-like peptide reaction. Does milk make you sneeze? If so, assume an intolerance to the immunological compounds and/or opioids. Does milk make you gain weight? If so, assume an opioid-like peptide reaction and/or sensitivity to IGF. Does milk provoke seizures? If so, you may need to test your reaction to calcium.

For suspected opioid-like peptide responders, individuals should test A1 milk (regular cow's milk) versus A2 milk (Guernsey cow, goat's and sheep's milk). People who are intolerant of opioids usually tolerate A2 milk unless they are super-responders. See the gluten and casein responders page.

Cream and Butter

Casein: opioid-like peptides (trace amounts - super-responders only)

Insulin-like growth factor I (trace amounts - super-responders only)

? Carotinoids including beta carotene (super-responders only, particularly in Jersey and Guernsey cows)

Lactose (trace amounts)

? Arachidonic acid (super-responders only)

Hope these are of use.

I've been wondering the same thing, since I don't tolerate A1 casein well, but do have 100ml (2.6g lactose, 1.g protein) or so of cream per day. Cream certainly doesn't give me the same brain fog as a large dose of casein will, but impossible to tell whether or not it is still having an effect, just a very subtle one.

I think I might experiment with cutting out cream and relying on butter instead, since I've no idea how much casein/lactose is required to have an effect. Also cream is such a tempting food, and perhaps because it's liquid, it's easy to just drink even when you're not really hungry. I can't see myself having a slice of butter for fun, in the same way!

I eat butter a lot and drink whipping cream sometimes with a meal. I don't seem to have any problems. I would like to mention that if you ever thought of making your own butter, you start with whipping cream and basically beat the shite out of it. You end up with butter and buttermilk. If whipping cream gives you a problem and butter doesn't, then you'd just about have to narrow the problem down to buttermilk and it's components.

Half and half will give me a runny nose if I drink too much of it, but not so with heavy cream. Oh, and, David, I have been know to have slices of butter for fun. Especially if it's chilled.

I've just gone back on heavy cream and whey protein after a month off all cow dairy except butter. Before the elimination experiment, I had a rash on my nose. With elimination, it went away, but now it's back. With what's been said above, I think I'll try eliminating the whey protein to see if there is a dose issue. Here's hoping.

I (mood and skin issues) can only handle ghee

I'm lactose-intolerant -- even the vaunted raw grass-fed (and expensive!) milk has me cramping and scampering to the toilet within an hour -- but heavy cream doesn't affect me and neither does cheese, yogurt, butter. Just hold the milk, thanks.

Heavy Cream is as close to dairy as a flank steak is.

I am trying to get rid of intestinal yeast, I just read that I can not have any dairy because of the "milk sugar" I only drink heavy cream, nothing else. Do I have to give up cream?

I can not drink milk. Runs, for sure. However, I eat butter daily. Cheese less so but I do have maybe 5-10 ounces per week I'd say. No probs. I don't ever eat straight cream but I do have a little bit of sour cream or creme freche everyday with no digestion issues at all. These are in pretty small amounts, though. Pretty much as a dip for romaine pieces, celery pieces etc. Start small. Always start small. Pretty much with anything.

Conventional heavy cream bothers me only a little (excess mucus/sleepyness) and organic heavy cream does not bother my in any amount. YUM!!!!!

Same thing for half and half, but magnified reaction for conventional, and little reaction for organic.

I cannot tolerate dairy and avoid it completely though I dream of my favorite hard cheeses from time to time ...

I'm severely lactose intolerant on conventional milk, but I do just fine on raw and VAT pasteurized milk (both are grassfed- no idea if that makes a difference). I thought that I could do conventional heavy cream because of the lowered lactose, but I can't. Granted, my source is ultra-pasteurized, and has carageenan added to it, but the reaction is still there. I'm perfectly fine, though, with Seven Stars heavy whipping cream. I don't know if it's VAT pasteurized or not, but it doesn't have any additives. So, even if you have a bad reaction the first time, you may want to seek out different brands to experiment with.

Hi: You may know this, but carageenan is allergenic to many people, as well as liver toxic. I cannot touch the stuff--it gives me the runs. I used to think I was lactose intolerent until I figured this out. Read up on carageenan. It is probably something none of us should be consuming.

Milk and cheese make me quite sick. But I have no problems at all with butter or heavy cream lattes.

I can eat plenty of butter.. (bulletproof coffee!! :D) but even a little cheese or milk and I pay for it..
