n the whole popular beliefs, based in or not, we should try to analyze which alimentary combinations are considered beneficial and which one is pernicious.

The most amazing thing is not the short of scientific rigor that supports the affirmations considered as a creed, but the high level of acceptance among the big public with a wrong belief.

The muscular delayed pain after an exercise of considered intensity and closely related to micro torn of connective muscular tissue in actions of eccentric nature (when de muscle is lengthened into a resistance), continues in the popular mythology linked to the well known glass of water with sugar.

But obviously it easier to say that a consumption of watermelon (90% water contained) at dinner is the reason of a difficult digestion than knowing the pH of a food, the grade of gastric hollow and the level of intestinal absorption in itself, the chemical agents called enzymes that intervene in the digestive process and apply biochemistry knowledge that could doubt the affirmation expressed above.

Anyway not everything is negative, there are many important good nutritional choices in the popular knowledge, (if not, we weren’t nowadays here)

Anyway not everything is negative, there are many important good nutritional choices in the popular knowledge, (if not, we weren’t nowadays here), for example the cereals consumption like rice, high in metionina, with legumes like chickpeas, high in lysine that entail and optimum protein complementarity against shortage of animal sources.

Therefore, we are going to develop some issues related to the more or less right food combination and we will mention:

The milk consumption with other high-protein foods like meats, make the calcium absorption from the milk is against the iron absorption from the meats, not only avoiding their own assimilation, but the peptic enzymes can’t digest properly the protein from the meats because the milk makes a film surround them, almost impenetrable. Is acceptable the milk/cereals combination (rice with milk, “gachas” with milk…) and milk with starches (mashed potatoes with milk…).

The acid fruits (citrics) with sweet fruits (dates, ripe bananas…) in the same consumption could provoke a no wished sugar fermentation in the stomach faced with the enzymatic incompatibility of acting in an effective way in acids and alkaline extreme environments.

There is a belief which says that rices and other cereals, tubers and roots don’t mix with citrics, vinegars, strawberries, acid apples, … (dressed potatoes, migas with orange, …) based in the fact the first enzyme in the carbohydrates consumption, the saliva amylase from the mouth, is inhibited in an acid environment, but is also true that the digestive process continues with absolute efficiency in the small intestine with the intestinal and pancreatic enzymes.

The proper combination of ascorbic acid (lemons) and acetic acid (vinegar) with meats promotes and improves the absorption of the valuable iron as a hemo, while the consumption of those meats with sweet products in the same meal will become a defective digestion which generates flatulencies by fermentation.

The consumption of different high protein foods in the same meal (meats, fishes, birds…) are going to provoke a slower and more laborious digestion with a worse amino acids assimilation.

At the most, the more complex digestions than the organism can carry out are high fats and proteins foods and meals combinations (fatty meats and meats, eggs, fishes and nuts with creams and sauces or fatty creams).

Once more, if I’ve achieved the fact of wake your interest up in these topic, I feel proud of it.
