Over 20 different kinds of Viruddhaahara have been identified in Ayurveda. Some of these are:
Rasa virudha : Substances having sweet taste ( like milk) should not be consumed with substances having sour taste ( fruits like grapes) in a very strict sense, it os hence unhealthy as per the norms of Ayurveda to drink the popular milk shakes of today.
Samskaraviruddha :These are food articles antagonistic in the way they are processed. Samskara means processing a food item to change its qualities, for example, by roasting, frying, steaming etc. some healthy food substances produce harmful qualities when they undergo specific processing methods. Curds or honey on heating become harmful to the body.
Viryaviruddha : This refers to food articles that must not be mixed together owing to their virya. Virya is the potency of a food that can produce either hotness or coldness in the body while undergoing digestion. For instance, a food item prepared by using milk/ buttermilk and fish together becomes antagonistic as milk as of sheethavirya(producing coldness) while fish is ushnavirya(producing heat).
SamyogaViruddha : This refers to food substances antagonistic due to the process of mixing. For instance, a mixture of fruits with sour taste and milk is contra indicated. Also, a mixture of fish with curd, or of alcohol with milk products is antagonistic to each other.
Pakaviruddha : These are articles antagonistic in the way they are cooked. Uncooked food or partially cooked food is unhealthy.
Agni Viruddha : This means incompatibility due to a difference in the food ingested and agni ( digestive capacity of an individual ) . For instance, if a person with mandaagni (diminished digestive power) consumes a lot of food then it keeps piling up, leading to indigestion and disease. This will require him to fast. Similarly a person with pitta predominance will have tikshnaagni (increased digestive capacity) and has to take food article which are guru (heavy), Snigdha (oily) and manda (foods requiring a long time for digestion).
Satmyaviruddha : A person acquainted with certain food habits should not change his food habits all of a sudden. An abrupt change to a new food regimen is known as satmyaviruddha.
Doshaviruddha : Every person has a normal constitution and due to this, he is prone to certain likes and dislikes from birth. The vata constitution types can stay healthy by taking foods which are oily and heavy in nature and stable. Foods of these qualities help vata function normally. But, if a person consumes a diet with bitter, pungent and astringent and light then it will lead to the manifestation of disorders of vata.

Dinner should ideally be taken before sunset and it is advisable to retire to bed 2-3 hours after taking dinner.
