Fiber - Vitacost

  • Fiber reduces the absorption of many minerals. However, high-fiber diets also tend to be high in minerals, so the consumption of a high-fiber diet does not appear to impair mineral status. However, logic suggests that calcium, magnesium and multimineral supplements should not be taken at the same time as a fiber supplement.
  • Bran, an insoluble fiber, reduces the absorption of calcium enough to cause urinary calcium to fall

Fiber’s Effect on Blood Glucose - MyFreeStyle.com

  • Functional fiber, or fiber that has been man-made or
    extracted from a food, doesn’t have the same nutritional benefits as dietary
    fiber.3 Examples of functional fiber include fiber supplements used
    to treat constipation and fiber added to processed foods. When taking fiber
    supplements, pay special attention to the manufacturer’s instruction on
    drinking plenty of water. Every little bit counts, but try to get most of your
    daily fiber intake from natural dietary fiber rather than from functional
    fiber.

Composite primary key: to use or not to use - Stack Overflow

Surrogate vs composite primary key.

  • believe that composite keys create a very natural and descriptive data model. My experience comes from Oracle and I don't think there is any technical issues when creating a composite PK. In fact anyone analysing the data dictionary would immediately understand something about the table. In your case it would be obvious that each source_id must have unique id_on_source.



    The use of natural keys often creates a hot debate, but people whom I work with like natural keys from a good data model perspective.

    yes, but joining from a child table to a primary key tends to get messy if you have to join on two, three, four conditions - and it bloats the primary key and thus all your indices. It might feel natural, but in reality, it's not a good idea – marc_s Sep 5 at 11:58


     


     

    point taken. Usually you will find that primary entities will have DB generated unique key. e.g. Customer table with CustomerId. Its usually secondary related tables that have composite keys and most of them has no FK referencing them. e.g. if you store history of customer phone numbers then in a Customer_contact_history table the columns CustomerId, phone, changedate may be composite PK as these 3 things are naturally unique. – Pratik Sep 5 at 13:43
