LG und schönes Wochenende!

Ich hab gehört, dass in Avocados auch verhältnismäßig (für ne Pflanze) viel Vitmin D enthalten sein soll. Stimmt das und wenn ja, gibt es ein pflanzliches Lebensmittel, das mehr hat?

Die Hauptsaison für Avocados beginnt im August und geht bis in den Mai. Die Früchte sind natürlich auch im Sommer erhältlich, aber das bessere Aroma weisen die Herbst-Avocados auf.

Eine reife Avocado erkennt man in der Regel nicht an der Farbe der Schale, ein deutlicher Indikator für die Reife ist die Konsistenz des Fruchtfleisches welche man mit einem Drucktest durchführen kann:

-Bei leichtem Druck mit den Fingern auf die Frucht sollte sie nur leicht nachgeben und sich nicht zu matschig anfühlen, dann ist sie reif.
-Fühlt sie sich noch hart an, ist die Frucht noch nicht reif.

Das einzige Land in Europa, dass Avocados anbaut ist Spanien, dort ist die Erntesaison von November bis Mai, dann kann man also die frischesten udn am wenigsten weit gereisten Avocados konsumieren!

Avocados tragen viel Vitamin D in sich. In 100 g sind bis zu 3,43 µg enthalten.

Das Vitamin sorgt für eine Regulierung des Kalzium- und Phosphorhaushalts und damit für den Aufbau von Knochensubstanz. Aufgrund eines Mangels kann bei Kindern eine Rachitis (es kommt zu Knochenverformungen) auftreten. Bei Erwachsenen ist eine Osteomalazie (gekennzeichnet durch Knochenerweichung) möglich.

Avocados haben Potential zur Prävention gegen Neurodegenerative Erkrankungen.
Avocado as a Major Dietary Source of Antioxidants and Its Preventive Role in Neurodegenerative Diseases

Zitat

Abstract:
Avocados have a high content of phytochemicals especially antioxidants with potential neuroprotective effect. Aging is the major risk factor for neurodegenerative diseases such as Alzheimer's and Parkinson's diseases. A large body of evidence indicates that oxidative stress is involved in the pathophysiology of these diseases. Oxidative stress can induce neuronal damages and modulate intracellular signaling, ultimately leading to neuronal death by apoptosis or necrosis. There is evidence for increased oxidative damage to macromolecules in amyotrophic lateral sclerosis, Huntington's disease, Parkinson's disease, and Alzheimer's disease. Thus, antioxidants have been used for their effectiveness in reducing these deleterious effects and neuronal death in many in vitro and in vivo studies. The critical review results indicate that compounds in avocado are unique antioxidants, preferentially suppressing radical generation, and thus may be promising as effective neuropreventive agents. The diverse array of bioactive nutrients present in avocado plays a pivotal role in the prevention and cure of various neurodegenerative diseases.

Avocados zur steigerung der Insulinsensitivität und zum Schutz der Mitochondrien vor Sauerstoffradikalproduktion?
Avocatin B Protects Against Lipotoxicity and Improves Insulin Sensitivity in Diet-Induced Obesity

Zitat

Abstract:
Scope: The effects of an avocado-derived fatty acid oxidation (FAO) inhibitor, avocatin B (AvoB), on glucose and lipid metabolism in models of diet-induced obesity (DIO) and in vitro models of lipotoxicity are evaluated. The safety of its oral consumption in humans is also determined.

Methods and results: Mice are given high-fat diets (HFD) for 8 weeks. Thereafter, AvoB or vehicle is administered orally twice weekly for 5 weeks. AvoB inhibits FAO which led to improved glucose tolerance, glucose utilization, and insulin sensitivity. AvoB's effects on metabolism under lipotoxic conditions are evaluated in vitro in pancreatic β-islet cells and C2C12 myotubes. AvoB inhibits FAO and increases glucose oxidation, resulting in lowering of mitochondrial reactive oxygen species that improves insulin responsiveness in C2C12 myotubes and insulin secretion in INS-1 (832/13) cells, respectively. A randomized, double-blind, placebo-controlled clinical trial in healthy human participants is conducted to assess the safety of AvoB consumption (50 mg or 200 mg per day for 60 days). AvoB is well-tolerated and not associated with any dose-limiting toxicity.

Conclusion: Therapeutic agents that are safe and effectively inhibit FAO and improve DIO-associated pathologies are currently not available. AvoB's mechanism of action and favorable safety profile highlight its nutritional and clinical importance.

Avocados zur verbesserung der Darmflora?

A new study suggests eating avocados daily for a 'happy' gut
A new study by researchers at the University of Illinois Urbana-Champaign suggests that people looking to balance their gastrointestinal health may be able to have their avocado toast and eat it, too.

The findings, which appear in the August 2020 issue of the Journal of Nutrition, imply that eating avocados daily can drastically improve a person’s overall gut health.

According to lead study author Sharon Thompson, the group wanted to deviate from the more obvious arguments in favor of the popular fruit. Multiple studies have attempted to link regular avocado consumption with weight loss or management. Instead, the University of Illinois researchers focused on how avocados affect the digestive system.

Says Thompson, “We know eating avocados helps you feel full and reduces blood cholesterol concentration, but we did not know how it influences the gut microbes and the metabolites the microbes produce.”

In their paper, the study authors note that avocado is also high in fiber and that research has shown high-fiber foods to be good for digestive health.
How the study came together

The research involved 163 participants between the ages of 25 and 45 years. The University of Illinois team hoped to gauge the effect of daily avocado consumption on individuals with overweight and obesity who were otherwise in good health.

The researchers divided the study participants into two groups. Over a 12-week period, one group ate a meal that included avocado. Each participant could have the replacement meal at breakfast, lunch, or dinner; the important factor was that they ate avocado as part of a single meal each day. The control group ate similar meals but without an avocado.

Members of both groups provided blood, urine, and fecal samples throughout the 3-month study period. All of the participants reported how much of the provided meal they ate, and, each month, they turned in a complete list of everything they consumed.

A positive outcome, but is there a catch?
Ultimately, the study showed that eating avocado with at least one meal per day leads to a greater presence of healthful microbes in the stomach and intestines. Additionally, the avocado group excreted slightly more fat in their stools than the control group.

“Greater fat excretion means the research participants were absorbing less energy from the foods that they were eating,” explains senior author Hannah Holscher. Holscher is an assistant professor of nutrition in the Department of Food Science and Human Nutrition at the University of Illinois.
