LUNCH VS DINNER

Healthy food refers to food that contains the right amount of nutrients to keep our body fit. We need healthy food to keep ourselves fit. But it is quite interesting to understand the regional and social differences in the names for meals.

BRITISH USAGE
(a) midday: dinner or lunch?
The midday meal is often called dinner, especially if it is the main meal of the day. People who are 'higher' in the social scale usually call it lunch.

Wikipedia says dinner usually refers to what is in many Western cultures the largest and most formal meal of the day, which many Westerners eat in the evening. On the other hand, lunch, the abbreviation for luncheon, is a meal eaten around midday.

(b) afternoon: tea
Some people have a light meal of tea and biscuits or cakes, called tea, at four or five o'clock in the afternoon.

(c) early evening: (high) tea or supper
Many people have a cooked meal around five or six o'clock. This is often called tea; some people call it supper.

(d) later evening: supper or dinner
A meal later in the evening is often called supper ( and some people use the same word for a bedtime snack). Some people use dinner for the evening meal if it is the main meal of the day. A more formal evening meal with guests, or in a restaurant, is usually called dinner.

AMERICAN USAGE

Americans generally use lunch for the midday meal and dinner or supper for the evening meal. However, in rural areas it is still common for the main meal of the day to be eaten at midday and called dinner, with the evening meal being called supper.

Celebration meals at Christmas and Thanksgiving are called Christmas/Thanksgiving dinner, even if they are eaten at midday.

I believe the information was quite handy.
