When I first started reading Ray Peat, I was somewhat incredulous at his recommendation to consume so much milk and cheese as well as at his belief that lactose intolerance problems are the result of various hormonal problems as opposed to simply the fact that most people in the world do not have genes for lactase persistence. In any case, even if Ray Peat is correct on all accounts, consuming high amounts of dairy on a healing program when you know it gives you issues sounds like a world of pain. I’ve come up with a few suggestions for those who still want to try Ray Peat’s dairy suggestions without actually consuming dairy.
Why Does Peat Recommend Dairy?
There appear to be three main reasons: dairy has an anti-inflammatory amino acid profile, dairy has pro-thyroid minerals, dairy has a high calcium/phosphorus ratio.
The Calcium/Phosphorus Ratio
There are lots of foods with a high calcium/phosphorus ratio but most of these are vegetables meaning that you’ll have to consume a relatively high volume of them in order to get enough (for 1g of calcium you need about 2-3lbs of collard greens or 19 oranges). You can also get a boost from molasses which has a great ratio and is high in many other minerals including magnesium (look for one low in iron).
Best: Dark leafy greens (especially collard greens, kale), molasses, oranges
I did a look on nutrition data in order to figure out how proteins compared to gelatin in terms of being high in proline, glycine, and alanine as well as which were low in methionine, cystine, and tryptophan. Here is some of what I found:
Low tryptophan: Milk, yogurt, oysters, clams, scallops, cuttlefish, squid
Low cysteine: Milk, yogurt, clams, oysters, snow crabs, cuttlefish
Low methionine: Milk, yogurt, clams, oysters, scallops
High glycine: Pork skin, pork ears, pastrami, crab, cuttlefish, lobster, veal liver, crawfish, scallop
High proline: Laver (seaweed), egg white, casein, beef spleen, tuna, pike, cod, haddock, whitefish, pastrami
High alanine: Ham, beef lungs, shrimp, beef round
Among these proteins, we have a few that are also high in cysteine, tryptophan, or methionine such as egg white (methionine, tryptophan, cystine), tuna (methionine, tryptophan), crustaceans (tryptophan), and dairy (cystine).
There are many pro-thyroid vitamins and minerals including vitamin A, selenium, zinc, copper, and iodine. Many of these are in dairy but they are also abundant in mollusks, crustaceans, liver, egg yolks, and seaweed.
What we can conclude from this is that, as a general rule, mollusks and crustaceans are your best source of protein in terms of amino acid profile and mineral content.
Best: Gelatin, oysters, clams, scallops, squid, octopus, crustaceans, liver, egg yolks, seaweed
To summarize, to get the right calcium/phophorus ratio you should consume dark leafy greens in high volume, oranges, and molasses. To get the right amino acid profile, vitamins, and minerals you should consume gelatin, mollusks, egg yolks, liver, crustaceans, and seaweed.
I forgot to mention the fact that Peat also likes dairy because of the fact that it inhibits iron absorption by its high calcium content. I would suggest that you eat your calcium rich foods together with your proteins for best results (and also with coffee, tea, or cocoa if you like as these also inhibit iron absorption). Egg whites are an interesting case in that they contain phosvitin which helps inhibit iron. It is also interesting to take note of the fact that many of the calcium rich greens (collards, spinach, chard, kale) contain oxalic acid which also inhibits iron absorption. You may also make a homemade calcium supplement by saving the eggshells from hard boiled eggs and grinding them into a fine powder; this powder will be calcium carbonate.
