Heilung, Prävention und Verjüngung durch Ernährung » Brombeeren

Brombeeren sind gesundheitlich auch nicht zu verachten. So wie auch Heidelbeeren sind sie tolle Lieferanten für Anthocyane.
Derzeit kann man sie noch reif und frisch von Sträuchern sammeln (oder die frisch geernteten im Geschäft kaufen).

Warum Brombeeren so gesund sind

Abstract:
Berries and other anthocyanin-rich treatments have prevented weight gain and adiposity in rodent models of diet-induced obesity. Their efficacy may be explained by modulation of energy substrate utilization. However, this effect has never been translated to humans. The objective of this study was to evaluate the effects of berry intake on energy substrate use and glucoregulation in volunteers consuming a high-fat diet. Twenty-seven overweight or obese men were enrolled in a randomized, placebo-controlled crossover study with two treatment periods. Subjects were fed an investigator controlled, high-fat (40% of energy from fat) diet which contained either 600 g/day blackberries (BB, 1500 mg/day flavonoids) or a calorie and carbohydrate matched amount of gelatin (GEL, flavonoid-free control) for seven days prior to a meal-based glucose tolerance test (MTT) in combination with a 24 h stay in a room-sized indirect calorimeter. The washout period that separated the treatment periods was also seven days. The BB treatment resulted in a significant reduction in average 24 h respiratory quotient (RQ) (0.810 vs. 0.817, BB vs. GEL, p = 0.040), indicating increased fat oxidation. RQ during the MTT was significantly lower with the BB treatment (0.84) compared to GEL control (0.85), p = 0.004. A 4 h time isolation during dinner showed similar treatment effects, where RQ was reduced and fat oxidation increased with BB (0.818 vs. 0.836, 28 vs. 25 g, respectively; BB vs. GEL treatments). The glucose AUC was not different between the BB and GEL treatments during the MTT (3488 vs. 4070 mg·min/dL, respectively, p = 0.12). However, the insulin AUC was significantly lower with the BB compared to the GEL control (6485 vs. 8245 µU·min/mL, p = 0.0002), and HOMA-IR improved with BB (p = 0.0318). Blackberry consumption may promote increased fat oxidation and improved insulin sensitivity in overweight or obese males fed a high fat diet.

Auch ein positiver Einfluss auf das alternde Gehirn ist zumindest in Raten gezeigt worden:

Effects of blackberries on motor and cognitive function in aged rats

Abstract:
The polyphenolics in fruits and vegetables, when fed to rats from 19-21 months of age, have been shown to retard and even reverse age-related decrements in motor and cognitive performance. These effects may be the result of the polyphenols increasing antioxidant and/or anti-inflammatory levels, or by direct effects on signaling, in the brain. Increased dietary intake of berry fruit, in particular, has a positive and profound impact on human health, performance, and disease. Thus, the present study examined a 2% blackberry-supplemented diet for its effectiveness in reversing age-related deficits in behavioral and neuronal function when fed to aged (19-month-old) Fischer 344 rats for 8 weeks. The results showed that the blackberry diet improved motor performance on three tasks which rely on balance and co-ordination: the accelerating rotarod, wire suspension, and the small plank walk. Results for the Morris water maze showed that the blackberry-fed rats had significantly greater working, or short-term, memory performance than the control rats. These data support our previous investigations in which we have seen improved motor and cognitive performance in aged rats after supplementation with other berry fruits.

Eine neue Studie zeigte, dass die Fütterung mit Brombeeren allergisch bedingte Entzündungen in der Haut reduziert. Ich denke mal weiter, dass es alle Entzündungen in der Haut reduzieren könnte und somit ein vorbeugendes Mittel gegen Hautalterung und Hautkrebs sein kann.

In mouse study, black raspberries show promise for reducing skin inflammation
Early findings indicate eating the fruit could help with skin allergies
In a study done with mice, researchers found that a diet high in black raspberries reduced inflammation from contact hypersensitivity -- a condition that causes redness and inflammation in the skin.

The Blackberry Fruit: A Review on Its Composition and Chemistry, Metabolism and Bioavailability, and Health Benefits

Blackberry (Rubus sp.) fruit contains high levels of anthocyanins and other phenolic compounds, mainly flavonols and ellagitannins, which contribute to its high antioxidant capacity and other biological activities. Blackberry phenolic composition and concentrations are known to be influenced by genetics, growing conditions, and maturation. Despite the current knowledge of their chemistry, research specific to blackberry phenolic compounds' health benefits, metabolism, bioavailability, and mechanism by which they confer health benefits is scarce. Blackberry phenolic compounds have protective effects on age-related neurodegenerative diseases and bone loss in vivo and can inhibit low-density lipoprotein and liposomal oxidation in vitro. Blackberry extracts have also exerted antimutagenic effects in vitro and in vivo by modifying cell signaling pathways and suppressing tumor promotion factors. However, the antiobesity, antidiabetic, antimicrobial, and anti-inflammatory properties of blackberry phenolic compounds need investigation. Similarly, studies that elucidate the in vivo physiologically effective concentrations of blackberry phenolic compounds are necessary.

Es ist schade drum, wenn man diese leider sehr schnell verderblichen Früchte an den Sträuchern oder Geschäften verderben lässt!

Das süß-säuerliche Aroma der Brombeere ist besonders erfrischend. Ihre typische Farbe erhält die Brombeere von den enthaltenen Flavonoiden. Diese Stoffe haben zahlreiche gesundheitsförderliche Wirkungen. Brombeeren aus heimischem Anbau sind von Juli bis in den Oktober erhältlich

Die Brombeere hat pro 100 Gramm nur 44 kcal. Sie enthält neben Vitamin C und E die Vorstufe zum Vitamin A. Brombeeren enthalten u.a. die Mineralstoffe Kalzium, Kalium und Magnesium. Die enthaltenen Flavonoide (Anthocyane), die der Brombeere die typische Farbe verleihen, haben zahlreiche gesundheitsförderliche Wirkungen, u.a. können sie das Risiko für Krebs und Herz-Kreislauf-Erkrankungen senken, den Blutdruck regulieren und das Immunsystem positiv beeinflussen.
