HUMAN NUTRITION

Detailed explanation-1: -Most bacteria will not grow at pH levels below 4.6 because the environment is too acidic. Thus, acidic foods, like vinegar and fresh fruits (especially citrus), seldom provide a favorable climate for pathogenic bacteria.

Detailed explanation-2: -Different types of food poisoning bacteria can live on a range of foods but most prefer food that is moist and high in protein. For example: Meat, poultry, eggs, shellfish, milk and dairy products, cooked rice, pasta and any product made from the foods listed.

Detailed explanation-3: -Most pathogens can grow at pH values between 4.6 and 9.0, but very acid or sour foods (pH below 4.6) discourage the growth of many microorganisms. Foods with a pH less than or equal to 4.6 are called high acid foods.
