There are a number of theories as to the combinations of foods, but since one contradicts another, they cannot all be correct, and, therefore, rather than convincing, they are creating doubts as to whether there is anything to be worried about after all.
People, though, lived and kept well all through the centuries without giving even a thought to food combinations. Why? Stop and think: Only since the years of modern transportation and commercial preparations of foods has this matter urged itself upon the public at large. This being so, the trouble is obvious: Modern transportation facilities, as previously pointed out, have flooded the markets with imported foodstuffs from all parts of the world, making it possible for anyone to purchase out-of-season foodstuffs and, in many instances, of the kinds that the consumer’s locality does not even grow. Naturally, then, these foreign, off-season products cannot combine well with the local seasonal ones. Herein mainly lies the trouble with food combinations. Again, consider what results you will obtain if you have both the heating system and the cooling system in your home going at the same time!
And, moreover, food that is adaptable to the consumer’s body needs in one climate may not be in another. This is discernible from the fact that in the days when people lived entirely on what they raised in their own localities, they did not have the trouble that the world is now having. The same truth is manifested in the fact that the Creator caused certain kinds of foodstuffs to grow in one locality and other kinds in another locality but at the time created no means for quick distant transportation.
Specifically speaking, there are on the one hand health authorities who maintain that protein foods such as “milk, cheese, eggs, nuts, and beans,” make bad combinations with carbohydrate foods such as “artichokes, bread, barley, cereals, cakes, flour, potatoes, pumpkins rice and spaghetti.” On the other hand, there are health authorities who hold that these two classes of food combine excellently. Who is right? — In view of the fact that cheese, eggs, and milk are made up of grains and grass, it seems illogical to conclude that a grain-and-vegetable product cannot combine well with grains and vegetables. Moreover, we might well observe that calves grow perfectly healthy on meals made up of milk, grain, and grass.
Then there is the contention that grains and vegetables ought never be combined. But contrary to this theory, cattle are raised best on grass combined with grain.
Moreover, grain is seed, and seed is nothing less or more than the fruit of vegetables.
Now comes the question: Should grain be combined with fruit? — As far back as history records, man has followed the custom of eating bread with every meal, and no past generation has left a complaint of ill effects on health.
The most popular question to be answered with reference to food combinations is that of whether fruit should be combined with vegetables. The solution to this question may be found in the laws which were ordained in the week of creation. Not given the same degree of intelligence as man, the cow was made to live on grass exclusive of fruit, and the monkey was made to live on fruit exclusive of grass. This we know from the fact that cattle are well equipped to help themselves to grass, and monkeys, to help themselves to fruit. Moreover, cows do not naturally care for fruit, and monkeys do not naturally care for grass so long as fruit is available. From these examples in nature we might logically conclude that not all fruits should be mixed with all vegetables.
When one considers that milk is made up of both grain and grass properties, and that although grain combines with fruit, grass does not, therefore the combination of milk and fruit, generally speaking, is somewhat questionable.
