Aunque hay algún paper por ahí que dice que el Aloe Vera tiene B12 activa, yo no me lo acabo de creer, pero si que he visto que recientemente se ha descubierto que el Aloe Vera en consumo, aumenta la biodisponibilidad de la b12 de nuestra mucosa oral, y la ingerida en los alimentos.
]Aloe vera is a powerful complement to other supplements, enhancing their absorbance and effects[/B].
Published: Devaraj S, et al. Aloe supplements enhance bioavailability of vitamin C and B12 in older adults. FASEB J: Exp Biol 2007 Abstracts 8.1-701.35. ?Washington, DC; 2007;Apr 28-May 2.
Abstract: Vitamin/supplement intake is associated with decreased mortality. Aloe vera, a botanical is consumed by 50 per cent of the US population and may affect bioavailability of vitamins. In a small study, aloe improved vitamin C absorption. Since oral B12 is deficient in vegetarians and in ageing, we tested the effect of two aloe vera preparations compared to placebo on the bioavailability of vitamins, C and B12, in older healthy human volunteers. In a randomised cross-over trial, subjects (40—80 years, n=15) received either aloe whole leaf extract (AL with vitamins B12, 1mg, and vitamin C 500 mg) or aloe fillet gel (AG with vitamins) or water (with vitamins) and blood was obtained fasting and following 1, 2, 4, 6, 8 and 24 hours post-ingestion of aloe/water with 1 week between treatments.
AG and AL did not affect lipids or glucose. AG significantly increased plasma oxygen radical absorbance capacity (ORAC) at 4 and 24 hours while AL significantly increased it at 4 hrs compared to baseline and placebo (AUC, 24h). AG significantly increased plasma vitamin C at 4, 6, 8 and 24 hours and AL significantly increased it at 4 and 6 hours (AUC, 8 and 24 hours). AG and AL significantly increased serum vitamin B12 levels at 1 and 2 hours.
Aloe preparations are well-tolerated and enhance bioavailability of vitamins C and B12 and ORAC. This could have major implications with regards to supplementation of vitamins to target chronic diseases, especially in elderly.
Potential applications: Consuming aloe vera, in foods, beverages or supplements, along with vitamin supplements would be beneficial especially among populations for whom B12 deficiency is an issue, such as the elderly.
En resumen, el consumo de aloe vera, aumentó los niveles plasmáticos de vitamina C y vitamina B12 ya al cabo de 2 horas.
El Aloe Vera tiene muchos nutrientes que junto con esto la hace un interesante ingrediente para la cocina.
No me da tiempo a traducirlo, así que remarco en negrita, lo interesante que creo que se entiende bien.
Vitamins
The plant contains many vitamins, excluding vitamin D but including the important antioxidant vitamins A, C and F. Vitamins B (thiamine), niacin, vitamin B2 (riboflavin), choline and folic acid are also present. Some authorities suggest that there is also a trace of vitamin B12 (Coats1979).
Enzymes
When taken orally, several of these biochemical catalysts, such as amylase and lipase, can aid digestion by breaking down fats and sugars. One important enzyme, a carboxy-peptidase, inactivates bradykinins and produces an anti-inflammatory effect. During the inflamma-tory process, bradykinin produces pain associated with vasodilation and, therefore, its hydrolysis reduces these two components and produces an analgesic effect (Obata et al 1993, Shelton 1991).
Minerals
Sodium, potassium, calcium, magnesium, manganese, copper, zinc, chromium and iron are all found in the aloe plant. Magnesium lactate inhibits histidine decarboxylase and prevents the formation of histamine from the amino acid, histadine (Shelton 1991 OJO ESTO PARA LAS ALERGIAS ALIMETNARIAS!!! QUE ES MUY BUENO.). Histamine is released in many allergic reactions and causes intense itching and pain. The prevention of its formation may explain the antipuritic effect of aloe vera.
Sugars
Sugars are derived from the mucilage layer of the plant under the rind, surrounding the inner parenchyma or gel. They form 25 per cent of the solid fraction and comprise both mono- and polysaccharides. By far the most important are the long chain polysaccharides, comprising glucose and mannose, known as the gluco-mannans (Beta - (1, 4) - linked acetylated mannan). When taken orally, some of these bind to receptor sites that line the gut and form a barrier, possibly helping to prevent ‘leaky gut syndrome’. Others are ingested whole by a method of cellular absorption known as pinocytosis. Unlike other sugars which are broken down prior to absorption, the polysaccharides are absorbed complete and appear in the blood stream unchanged. Here, they act as immuno-modulators — capable of enhancing and retarding the immune response (Green 1996, Kahlon etal 1991, Sheets etall9gi).
Anthraquinones
These phenolic compounds are found in the sap. The bitter aloes consist of free anthraquinones and their derivatives:
* Barbaloin-lO- (1151 — anhydroglucosyl) — aloe-emodin-9-anthrone)
* lsobarbaloin
* Anthrone-C-glycosides and chromones.
In large amounts these compounds exert a powerful purgative effect, but when smaller they appear to aid absorption from the gut, are potent antimicrobial agents (Lorenzetti et all 964, Sims eta/i 971 a), and possess powerful analgesic effects. Topically, they can absorb ultra violet light, inhibit tyronase activity, reduce the formation of melanin and any tendency to hyper-pigmentation (McKeown 1987, Strickland eta/i 993). Lignin This woody substance, inert in itself, endows topical aloe preparations with their singular penetrative ability to carry other active ingredients deep into the skin to nourish the dermis (Coats 1979).
Saponins
These soapy substances form 3 per cent of the gel and are general cleansers, having antiseptic properties (Hirat and Suga 1983).
Plant
Sterols These include Campesterol, f3 Sitosterol and Lupeol (Coats 1979).
Sallcylic acid
This is an aspirin-like compound possessing anti-inflammatory and antibacterial properties. Topically, it has a kerolytic effect which helps to debride a wound of necrotic tissue.
Amino acids
These are the building blocks of proteins. Aloe vera gel provides 20 of the 22 necessary amino acids required by the human body and seven of the eight essential amino acids which the body cannot synthesise. These must be ingested in food.
