SECTION II.
Analysis of Nutritional Comparison Data--
Making Sense of the Numbers


A series of short tables, with discussion, is provided here to analyze and summarize the voluminous data of Section I. These tables compare human milk, goat milk, and the two fruit averages specified in Table 3.0 of Section I by a variety of criteria.

Goat milk is used in the analysis, rather than cow's milk, for a number of reasons:

Note to those who have not read the Nutritional Comparison Tables in Section I: The term "4 Sweet Fruits blend" mentioned below is an average of: apples, mangos, oranges, and watermelon. The term "3 Sweet + Avo blend" (abbreviated as "3 + Avos" in some tables) is a weighted average of: mangos, watermelon, oranges, and avocado.


Let us begin by looking at the calorie breakdown, as follows.

Milks vs. Fruit Blends

Units: % of total calories, for each food item.

(Column totals = 100%; minor deviations possible due to roundoff error.)

From the above, we see that the composition of human milk (and goat milk) is clearly different from that of sweet fruits. In caloric terms, human milk is ~52.5% fat, i.e., it is a "fatty food," while sweet fruits are ~85% carbohydrate (sugar), i.e., they are a "sweet." Adding avocados to the fruit blend increases the fat and decreases the sugar content, but even the "sweet fruit + avocado" blend is still ~54.5% sugar. The carbohydrate composition is discussed further, below.

What appear to be differences in proximate composition, as illustrated by Table 4.0, can be statistically tested via a t-test, using the raw data (rather than the calorie data). Using the t-test, we test the hypothesis that the average (fat, carbohydrate) levels in the "4 sweet fruits" group equals the (fat, carbohydrate) levels found in human milk. The result of such tests, i.e., the t-statistics for the test, are as follows.

Note that the t-tests above yield a significant difference; which means that we reject the hypothesis that the fat and carbohydrate levels are equal for fruit and milk. Thus we conclude that the (gross) levels of fat and carbohydrate (sugar) for human milk vs. sweet fruits are not equal, i.e., are different. Inasmuch as fat and sugar are profoundly different energy sources, this test immediately indicates that, regardless of the results of comparisons of other nutrients, milk and sweet fruits are, in fact, different foods--they are not similar or "just like" each other.

Remark: most people have common sense and can tell the difference between sugar and fat. However, it appears that some fruitarian extremists have a serious problem in this regard. :-)

Vitamin and mineral comparison. Tables 1.0 through 3.0 in Section I provide details on the vitamin and mineral composition of human and goat milks vs. fruit blends. Examination of those tables reveals the following:


Let us next examine the amino acid profiles, as follows.

From the above, we see that the fruit-blend profiles appear to be quite different from the profiles for human and goat milk. Note the differences in aspartic acid, glutamic acid, proline, leucine, and others. A simple statistical analysis, presented below, reveals that goat milk is closer to human milk in amino acid profile than is fruit. Also observe that goat milk has more total protein than human milk, while fruit has considerably less.

Taurine: present in human milk, but not in fruit. Taurine is an important amino acid found in milk, but not in fruit. It is an essential amino acid for infants, and conditionally essential for adults. (Infants cannot synthesize adequate taurine.) Lack of taurine in infancy may cause vision defects and nervous system (brain) problems. See Gaull [1982] for information on taurine, also the section on taurine in the article Comparative Anatomy Brought Up To Date, available on this site.
