Probiotics :
Your gut is made up of trillions of bacteria. Probiotics are live microorganisms, similar to or the same as the ones that exist in your gut. They are found in fruits and vegetables that contain complex carbohydrates, like fiber and starch. These carbs can’t be digested by your body, so they bypass the digestive system and travel to your colon, where your gut’s microorganisms metabolize and ferment the prebiotics. When prebiotics are broken down, it creates different short-chain fatty acids. These short-chain fatty acids improve your metabolic and overall health by helping provide energy to your colon cells, producing necessary mucus, and aiding in reducing inflammation and promoting immunity. In short, think of prebiotics as the fertilizer to help good bacteria grow lactobasillus and Bifidobacterium are the most common.

Prebiotics :
Prebiotics are a type of specialized plant fiber that feed the microbes in your gut and stimulate the growth of healthy bacteria. They are found in fruits and vegetables that contain complex carbohydrates, like fiber and starch. These carbs can’t be digested by your body, so they bypass the digestive system and travel to your colon, where your gut’s microorganisms metabolize and ferment the prebiotics. When prebiotics are broken down, it creates different short-chain fatty acids. These short-chain fatty acids improve your metabolic and overall health by helping provide energy to your colon cells, producing necessary mucus, and aiding in reducing inflammation and promoting immunity. In short, think of prebiotics as the fertilizer to help good bacteria grow.

What are the benefits of prebiotics?
The benefits of prebiotics are wide-ranging and affect more than just your digestion. A healthy – or unhealthy – gut impacts several of your body’s systems and your overall health. Research has shown that prebiotics :

1)Improve digestion and metabolism
2)Help regulate bowel movements
3)Improve calcium absorption and increase bone density
4)Regulate blood sugar and insulin resistance
5)Stimulate the production of hormones that aid in appetite suppression
6)Lower inflammation in the body
7)Strengthen the immune system
8)Help balance and maintain hormone levels
9)Reduce risk of allergy
10)Lower the risk of cardiovascular disease
11)Regulate moods and reduce stress hormone levels
12)Lower cholesterol level
13)Reduce risk of colon cancer

Which Foods Are Prebiotics?
Most prebiotic foods are oligosaccharide carbohydrates including galacto-oligosaccharides, starch and glucose-derived oligosaccharides, and others. Some examples of prebiotic foods include :
Aloe vera
Asparagus
Sugar beet
Garlic
Chicory
Onion
Jerusalem artichoke
Wheat
Honey
Banana
Barley
Tomato
Rye
Beans

Which Foods Are Probiotics?
Probiotics are commonly found in fermented foods since the fermentation process often causes these bacteria to grow. They are also added to certain foods, like yogurt. Here are some good food sources of probiotics :

Aloe vera
Yogurt
Kefir
Kimchi
Kombucha
Sauerkraut
Miso

Lactic acid bacteria are industrially important organisms recognized for their fermentative ability, as well as their health and nutritional benefits Low pH, gastric enzymes and bile salts are some of the gastrointestinal tract barriers that probiotic bacteria need to resist after being ingested Despite of numerous biological activities of aloe vera, particularly lantimicrobial and antioxidant activities, the leaf gel is prone to oxidation, which leads to fermentation.

Aloe vera is a source of essential micronutrients and active phytochemicals such as ascorbic acid, tocopherols and phenolic compounds which are able to reduce the free radicals that cause reactions of oxidation associated with cardiovascular diseases, carcinogenesis and aging. Many biological activities, including  antimicrobial, laxative, protection against radiation, antioxidant, anti inflammatory, anti-tumour, anti-diabetic, anti-allergic, as well as hypoglycaemic, gastroprotective, immunomodulatory and wound-healing effects, have been attributed to this plantgel.
Aloe vera is a substrate for lactic acid bacteria  fermentation is to increase the number of probiotic bacteria that become established in the digestive tract and provides health benefits.
