Increasing life expectancy related to nutrition throughout human history! 30,000 years ago, humans were collectors and sometimes hunters, or rather omnivores, fruits, tubers, mushrooms and animals, mainly insects or carrion. Due to the lack of carbohydrates and balanced, regular diet, the average life expectancy was about 20 years. That would be what we call paleolithic today. The first groups began to settle 10,000 years ago, which on the one hand meant better use of the fire not only for heating but also for cooking, on the other hand also the crossing and refinement of various plant species and the first animal husbandry. As a result, life expectancy almost jumped to 25. 5,000 years ago, the cooperation of larger communities, their organisation and the construction of the first food storage or silo, enabled a relatively regular supply of food. Life expectancy rose by another 5 years to 30. 3000 years ago, the vital salt (of course not in today's unhealthy quantities) became more widespread. The extraction of salt from mines or larger salt-water evaporation basins made more intensive collaboration between several individuals necessary. However, here, too, the average life expectancy improved by 5 to 35 years. By unifying the Mediterranean food market, first by the Phoenicians, Greeks, Romans and later Arabs and Crusades, the menu became more extensive. Various preservation methods that have developed over time, such as pickling in salt, sugar, fat, oil or smoke, cooking, baking and drying, dry storage or freezing, have also ensured the food supply during colder, warmer or drier, wetter times of the year. Vitamins in winter, fresh vegetables or fruit, strengthen the immune system. So today, we have reached 75 years. The problems we face today in modern societies in industrialised countries are overeating. Changes in living and working conditions require an increasingly conscious diet. Older people should eat very differently than younger people. Furthermore, as this brief overview shows, the human digestive system is unsuitable for any unbalanced vegetarian or paleolithic diet.
