“Can a person with heart disease drink coffee?” is one of the most common questions I’ve been asked, so let me clarify this matter here. Coffee is actually water, milk (whether whole, fat-reduced or non-fat), sugar and coffee. Some people like it with extra cream.
Coffee that we drink comes from two types of coffee beans: Robusta and Arabica. The flavours and smell vary according to the origins, how it’s roasted and how it’s brewed.
Generally speaking, there is no study that shows drinking coffee on its own (meaning no milk, cream or sugar is taken into account) could affect cholesterol level or heart disease risks. However, in the past two decades, some studies have found that unfiltered coffee could increase cholesterol level due to the release of a substance called diterpene cafestol, which increases cholesterol level, especially LDL cholesterol.
The hotter the water, and the longer the ground coffee is in contact with it, the more diterpene cafestol is released. Filtering your coffee will therefore reduce the substance. Instant coffee and percolated coffee have very little cafestol. Decaffeinating of coffee is not relevant to the level of this substance.
There was a study showed that drinking espresso, Scandinavian-style boiled coffee or French-pressed coffee can also increase cholesterol level if you drink 4-5 cups a day for 4 consecutive weeks. This could increase your LDL cholesterol by 8-10%.
Now, let’s look at the good side of coffee. Coffee is actually rich in phytochemical antioxidants. So in this sense coffee can also help fight LDL cholesterol. Some say that cafestol can kill cancer cells. Some report that coffee can help reduce risks for diabetes and Parkinson’s disease.
Some people say coffee is fattening – and it’s both true and fault. Coffee itself does not have any fat, but if you add sugar and milk, it can be a fattening drink. Most coffee drinks are delicious because of sugar and cream, but the calories you get from one glass could be as much as a main dish.
Many coffee shops are now adopting low-fat milk, but be aware that only a third of fat has been reduced. A large cup of coffee latte with low-fat milk still gives you 190 Calories and 7 grams of fat. The whole milk version gives 220 Calories and 9 grams of fat. A cup of rice gives only 100 Calories. Chocolate drinks of mocha that uses low-fat milk gives 400 Calories and 11 grams of fat, exclusive of the delicious fluffy whipped cream on top! A spoon of sugar in your drink gives about 16 Calories, but to make a delicious cup of coffee, you might need about 10 spoonfuls.
A patient of mine likes to go to coffee shop for coffee and free Internet. She kept gaining weight, so I told her to stop drinking coffee. She listened to my advice, but her weight still increased. She told me later that she switched from coffee to o-liang (iced black coffee with syrup) and drank about 10 glasses a day.
I cannot stress enough that when it comes to maintaining good health, everything in moderation is the best way to go. Drink responsibly!
