Factorability of the correlation matrix of the original nutrients: Bartlett’s test of sphericity and measures of sampling adequacy.

Bartlett’s Test of Sphericity:p-Value < 0.001
Overall Measure of Sampling Adequacy (Kaiser–Meyer–Olkin statistic) 1: 0.86
Individual Measures of Sampling Adequacy:
0.60–0.69	retinol, linoleic acid
0.70–0.79	total fiber, starch, vitamin E, monounsaturated fatty acids, vitamin D
0.80–0.89	lycopene, vegetable protein, other polyunsaturated fatty acids, riboflavin, animal protein, saturated fatty acids, sodium, calcium, iron, vitamin C, potassium, folate
≥0.90	phosphorus, niacin, zinc, thiamin, cholesterol, soluble carbohydrates, linolenic acid, vitamin B6, beta-carotene equivalents

¹ Overall and individual measures of sampling adequacy range between 0 and 1, with values > 0.60 indicating a satisfactory size.
