McClugage and Mendel (1) found the calcium of carrots and spinach to be poorly utilized by dogs. Rose (2), in calcium balance experiments with healthy young women whose intake was close to the estimated minimum for equilibrium, found the calcium of carrots almost as well utilized as that of milk, the carrots furnishing half or more of the total calcium of a mixed diet. Blatherwick and Long (3) likewise concluded that the calcium (as well as the phosphorus) of vegetables was satisfactorily…

Absorption of calcium from a leafy vegetable rich in oxalates.
TLDR
Recommendation of green leaves as a regular source of Ca to the vulnerable section of the Indian Community should be considered with caution since green leaves are a main source of other nutrients, especially β-carotene, their consumption cannot be discouraged and hence leaves low in oxalates should be recommended.
An attempt to measure the availability of calcium in edible leaves commonly consumed by South African negroes
TLDR
It was confirmed that the calcium in Swiss Chard “spinach”, (Spinacia oleracea) with its high oxalic acid content, is poorly absorbed, Nevertheless, it was inferred that thecium contained in leaves of “ spinaches” commonly consumed is available for utilization, a finding in agreement with observa...
Availability of calcium in some of the leafy vegetables
TLDR
All the five leafy vegetables form good sources of calcium from the point of nutrition, especially Avati Keerai, MolaKeerai and Chiru KeerAI, as the calcium in these are used as well as that in milk.
The comparative value of spinach and tomatoes in the child's diet
Summary 1. Cooked spinach and canned tomatoes are approximately of equal value as a source of iron for the prevention and cure of nutritional anemia in spite of the fact that the total iron content
The influence of a daily serving of spinach or its equivalent in oxalic acid upon the mineral utilization of children
TLDR
The practical conclusion drawn from the data recorded herein is that spinach is not harmful even in servings of 100 grams daily, at least in preadolescent children, but because of its richness in vitamins, minearls, especially iron, and other nutritive essentials it should retain its customary place along with other green leafy vegetables.
ADDITION OF VEGETABLE SOUP AND STRAINED VEGETABLES TO DIET OF ARTIFICIALLY FED INFANTS
Although modern pediatric practice emphasizes the early use of vegetables in the diet of the young child, there is a need for more definite scientific information on the age at which they can be
Bioavailability of Calcium from Sesame Seeds, Almond Powder, Whole Wheat Bread, Spinach and Nonfat Dry Milk in Rats
Calcium bioavailability (BV) from sesame seeds, almond powder, whole wheat bread, spinach, and nonfat dry milk (NFDM) was compared to calcium BV from a calcium carbonate (CaCO3)-supplemented control
Oxalic Acid in Foods and its Behavior and Fate in the Diet Three Figures
TLDR
It seemed desirable for higher accuracy, to make oxalate determinations under conditions that would avoid drastic treatment of the food and entail the concentration of the oxalates of a relatively large sample, freed from most of the other food constituents.
Oxalate content of some common foods: determination by an enzymatic method.
TLDR
Spinach, rhubarb, peanuts, chocolates, parsley and tea were found to contain high levels of oxalate, but beetroot was found to be five times as high as previously reported, but coca-cola and beer were almost free from oxalates.
Calcium assimilation in ruminants on oxalate-rich diet
SUMMARY 1. In a ration containing paddy straw, the large amount of oxalate ingested does not act in the same way in the ruminant system as has been observed when oxalate-rich spinach is fed to rats.
