ZOOCHEMICALS

¶  They refer to the natural, healthy 
        promoting components found
        in animal foods.
   These substances provide the animals 
            protection against disease.
   ¶ Zoochemicals come from the plants that 
            animals eat.

Resistant Starch—another form of Fiber

v   
v             vSoluble Fiber
Ø Found in fresh and dried fruit, oats, peas, beans, barley, seeds, psyllium, some vegetables
Ø Can help lower blood cholesterol and glucose levels
                  
 
   vInsoluble Fiber
Ø Found in whole wheat flour, wheat germ, unprocessed bran, nuts, many vegetables, whole grain bread and cereals
Ø promotes the movement of material through your digestive system and increases stool bulk
Ø The recommended amount of fiber is 25-38 grams per day.     
               
vResistant Starch
Ø It is a carbohydrate that is not digested in the small intestine. It passes into the large intestine where it is fermented.
Ø Found in beans, peas, lentils, whole or partially milled grains and seeds, potatoes, under ripe bananas, cooked plantains, barley, corn, brown rice, and oatmeal     Click to show "Plantain" result 8  
Ø Small amounts of resistant starch are produced by processing and baking of cereal and grain products. Examples are cooked and chilled pasta, cold rice and potato salad.
Ø They are found in many new functional fibers added to processed foods such as inulin, polydextrose, and indigestible dextrins.
Ø Hi-maize is a natural resistant starch made from high amylose corn that is not genetically modified. It is used to replace flour and is increasingly found in breads and pastas. It is available at King Arthur Flour, Ener-G Foods, and Wegman’s Super Pasta. It can be used as a replacement for wheat products required for gluten free diet.
                                                

Benefits of Resistant Starch
  •  Helps prevent constipation
  •   It is a prebiotic fiber. It encourages the growth of healthy bacteria in the  bowel and discourages the growth of harmful bacteria.
  •  Creates a more acidic environment in the intestine and reduces the production of harmful substances.
  •     Helps control blood glucose levels and may help to improve insulin resistance in people with type 2 diabetes.
  •  When added to processed foods they reduce the impact of that food to raise blood glucose.
  •  Increases absorption of minerals such as calcium.
  •  They block absorption of potentially toxic or carcinogenic substances
  •  They increase satiety or the feeling of fullness after a meal and may help in weight loss.
  •  When resistant starch is present in the diet, dietary fat is used first for energy before it has a chance to be stored as body fat. This may help with weight management.
  •  When added to food it does not affect taste or texture. It also lowers the calorie content of foods because it provides 2-3 calories per gram compared to 4 calories per gram for other carbohydrate foods.
  •  Up to 45 grams of fiber from resistant starch can be tolerated without digestive side effects due to its slow fermentation.
  •  Studies have shown that about 15-20 grams per day of resistant starch provides health benefits.

Note that you will not see “resistant starch” in the ingredient list. Natural resistant starch may be listed as fiber on the nutritional information label. Some resistant starches are labeled as “resistant cornstarch” or “corn starch”, “maltodextrin”, “modified food starch” or “dextrin”.

Prebiotics

 ·  They are nondigestible food fiber that stimulates the growth and activity of
     bacteria in the intestine.  

    How do Prebiotics work
 ·        They help probiotics grow in the gut.
·          ·         It is important to consume prebiotics with probiotics to encourage
           probiotic organisms to survive in the human gut.
·          ·        They consist mainly of soluble fiber and oligosaccharides which are
           carbohydrates.
·         ·         They release short chain fatty acids which decrease the pH of the colon.
     
        Benefits of Prebiotics
  •            The decrease in pH enhances mineral absorption, particularly calcium, iron, and magnesium possibly lowering the risk of osteoporosis.
  •            Decrease in pH also rid the gut of harmful bacteria
  •     They may decrease cholesterol and triglyceride levels
  •   Reduce the risk of colon cancer
  •     Promote better gut integrity and function
  •  Boost the immune system
  •  Stabilize blood glucose levels
  •  Help prevent constipation 
     Sources of Prebiotics
  •  Asparagus
  •  Bananas
  •  Barley
  •  Berries            
  •  Bran
  •  Chicory root
  •  Honey
  •  Garlic
  •  Jerusalem artichokes
  •  Leafy greens
  •  Leeks                 
  •  Legumes
  •  Oatmeal
  •  Onion
  •  Psyllium                      
  •  Rye
  •  Wheat
  •  Oligosaccharides
ü Fiber gums
ü Fructo-oligosaccharides (FOS)
ü Inulin
ü Isomalto-oligosaccharides
ü Lactilol
ü Lactosucrose,
ü Lactuloses
ü Oligofructose
ü Pyrodextrin
ü Soy oligosaccharide
ü Transgalacto-oligosaccharide (TOS)
ü Xylo-oligosaccharide

Prebiotics can be sprinkled on food; stirred into liquid; taken in capsule form; or purchased in prebiotic-fortified foods and beverages, such as sports drinks.              


                                    

Those who are immunocompromised or have inflammatory bowel problems should consult your doctor before taking these supplements.
