I can think of many reasons why someone would decide not to use milk as base for soylent, but personally I have no problems with milk. I like the taste, I digest it well, and I’ve been drinking it all my life. For my first soylent, I think I’ll use 1L of milk as a base. When I looked up the nutrients in milk, I found some interesting information.
1L of (whole) milk contains:32 gram of fat, 31 grams of protein and 51
gram of carbs.
Minerals: Calcium 1103mg (110%), Magnesium 97.6mg (24%), Phosphorus
888mg (89%), Potassium 1396mg (40%), Sodium 390mg (16%), Zinc 3.9mg
(26%), Selenium 36.1mcg (52%), Molybdenum 50 µg (111%)
Water-soluble Vitamins: B1 0.4mg (29%), B2 1.8mg (105%), B3 1.0mg
(5%), Choline B4 140mg (25%), B5 3.5mg (35%), B6 0.4mg (18%), Folate
B9 48.8mcg (12%), B12 4.3mcg (72%)
Some people may be afraid of the fat profile of (whole) milk, but
personally I think that especially grass fed whole milk has a really
good fat profile. Grass fed milk contains a perfect 1:1 omega 3:omega
6 ratio and it contains conjugated linoleic acid.
I especially like the fact that I don’t need to add phosphorus and calcium if I use milk as base. And 31 gram of protein and 32 gram of fat would save some money.
