L’Accademia del Fitness

cannot do without fruit and vegetables is a universal truth: the acid base vision can help our motivations to prefer this kind of food because of its positive effects. All these considerations on acidosis are of particular interest for people who practise sports who, on the one hand produce more acids as a result of their accelerated cellular muscular metabolism, on the other hand, especially in the case of power sports, they might not know which food choices to make to avoid acidosis. It might be useful when choosing food, to keep in mind PRAL: positive for acidifying, negative for alkalinizing food. I would like to make this clear: no food is to be absolutely avoided. Also acidifying food can be consumed as an integrating part of a healthy diet. What we must keep in mind is that the ratio between alkalinizing and acidifying food should be about 4 to 1. Food considered acidifying: meat, fish, eggs, seasoned cheeses (fresh cheeses are less acidifying), cereals (pasta made with processed flour is more acidifying than pasta made with integral flour) legumes, especially dried sweeteners and soft drinks coffee, tea, spirits sweets and all sweetened food Food considered alkalinizing: vegetables (especially uncooked) potatoes dry fruit (almonds, Brazilian nuts, figs, dates, raisins) with the exception of nuts and hazel nuts fresh ripe fruit, especially bananas, pears, melons (let us


consider the spontaneous natural popular wisdom of popular dishes such as ham and melon or pears and Parmesan cheese or bresaola and garden rocket; in these cases we have an opportune combination of acidifying food (ham, Parmesan and bresaola) and alkalinizing food (melon, pears, garden rocket). Fruit produces the so-called “volatile” acids which are eliminated with our breath; at the end of its metabolization, the alkalinizing effect of its mineral salts and vitamins remains. Eating a lot of fruit is not advisable in cases of a completely inactive life and old age, as it is more difficult to eliminate its acids and the resulting load of sugars through the lungs. Many people think that: “If some food is good for me, eating a lot of it will do me better”. Let us keep in mind the Latin saying “Est modus in rebus”... there is a measure in things which is a source of wisdom. Some portions of fruit are healthy, but kilos of fruit are not! In the second part we will analyse more closely what can be useful for people who practise sport in order to contrast acidosis which appears to be a silent, hardly known enemy of any intense physical activity which tends to be acid forming.
