Some popular breakfast choices may seem to be low calorie, but aren't

LONDON, June 4 (UPI) -- The calorie content of food can vary quite a bit depending on brand or how it is manufactured or even among different kinds of fruit.

For example, the candy maker Cadbury decided to stop manufacturing chocolate bars with more than 250 calories to help stave off obesity, but a bowl of Jordans Super Berry granola without milk -- which many may choose as a healthy breakfast -- contains 438 calories, the Guardian reported.

Just having coffee for breakfast can also pack on the pounds. A medium-sized Starbucks Mocha Frappuccino -- made with whole milk and whipped cream -- has 400 calories and almost half of a woman's daily recommended daily allowance of saturated fat.

Having only fruit for breakfast? Some may be temped to eat the the whole pineapple, which has more than 450 calories, but an average avocado -- yes it is fruit, a large berry that contains a single seed -- will have 275 calories.

However, a single serving of diced fresh pineapple contains 80 calories and is high in dietary fiber, very high in manganese, high in thiamin, high in vitamin B6 and very high in vitamin C, but it is also very high in sugar -- a serving contains more than 16 grams of sugar.

Even the calories of a serving of alcohol can vary widely. For example, a single Gordon's gin and tonic contains 72 calories, but a glass of medium white wine contains almost 200.
