The preserves were stored for 12 months at three temperatures: −20, 4 and 20 °C (±2 °C). Analysis was performed every 3 months, using HPLC-DAD and LC-MS. In the presented research the degree of degradation of the overall of ETs + EAC was determined and the transformation of individual ETs was described. The ratio of monomeric, dimeric, trimeric and tetrameric compounds with respect to the sum of ETs and EAC and changes in their concentration over time were also determined.

The environmental changes led to a change in diet quality (micronutrient density) because of changes in food foraging, which ensured that a growing brain was adequately supplied with energy and essential micronutrients for growth. The hippocampus is a direct link between nutrition and the environment, which is necessary for adapting to a changing climate. The adaptation then improves foraging success and enables better food quality and thus favors the development of the hippocampus, which in turn influences the development of other brain regions.</p><p>The extraordinary ability of our ancestors for persistent running not only favored hunting but also had direct effects on hormones that support brain development. The connection between physical exercise, nutrition, and plasticity of the hippocampus and the resulting adaptation to changing environmental conditions is essential for triggering or stimulating brain development. As the <em>variability selection hypothesis</em> proposes, fluctuations in environmental conditions need a short adaptive answer, which may become genetically fixed and selected. The presented hypothesis allows a meaningful combination of the different theories of brain development (pulse climate, variability selection, amplifier lakes) and nutrition theories (aquatic, cooking, energy).</p><p>The assumption that the hippocampus, as a “central sensory organ”, detects new events and enables an adaptive response is not an isolated assumption for the hippocampus since other brain regions can also react similarly with synaptic plasticity.

The objective of this study was to examine the phytochemical and polysaccharide compositions of commercially available baobab, moringa, and hibiscus ingredients from Senegal. Characterization of carotenoids, tocopherols, phenolic compounds, monosaccharide composition, and glycosyl linkage was carried out. We observed that moringa contained the greatest content of carotenoids and tocopherols. Moringa also contained significant amounts of the flavonols quercetin 3-<em>O</em>-glucoside and quercetin 3-<em>O</em>-rutinoside, while baobab had greater concentrations of flavan-3-ols. Substantial content of anthocyanins was observed for hibiscus, but not moringa or baobab. The predominant monosaccharide in baobab was xylose, while hibiscus was a combination of xylose, galactose, and glucose. The primary monosaccharides in moringa were galactose and glucose.
