Coffee wakes you more than morning – bitter drinks have been linked to type 2 diabetes, heart disease and low risk of death. But Depending on what you add to your coffee, you cannot remove these health benefits From your cup which, a new study shows.
Researchers found that those who drank One to two cups of coffee daily One was 14% lower risk of mortality rate Compared to non-coffee drinkers.
However, that was Only true For those who took their coffee Black, or with small amounts of cream, milk, or sweetness. Many additives appeared weak Health Benefits of Coffee,
“If we add too much sugar or saturated fat to our diet, it grows[s] Our total [caloric] Consumption, which can also be associated with adverse health results, said the senior study author said Fong Fong Zhang, MD, PhDProfessor at Tufts University Friedman School of Nutrition Science and Policy,
For this study, published in May The Journal of NutritioN, Zhang and their colleagues chased over 46,000 American adults during nearly 10 years. The goal was to see if the risk of mortality was related to the habits of drinking coffee of the participants.,
At the beginning of the study, the researchers gave a 24 -hour diet questionnaire to the participants. Based on that information, the researchers estimated the average coffee consumption of the participants and asked if they have added sweetness or products. Saturated fat For their coffee.
After monitoring the health of the participants – the deaths recorded from cancer, cardiovascular diseaseAnd all reasons -Jhang and his team found:
- Drinking One cup Was connected to coffee every day 16% lower all causes mortality risk
- Drinking Two or three daily cups Coffee All causes risk of mortality 17%
Coffee drinkers also had 29-33% less risk of heart disease mortalityespecially.
Especially when looking at coffee additives, researchers found that, compared to non-coffee drinkers, participants have A 14% lower risk of overall mortality If they drank black coffee Or Coffee low in added sugar and saturated fat.
Research team defined “Low couple sugar” And “Low saturated fat” As any amount below 5% of the recommended daily value. 8-Oons for decoction, it translates:
- 2.5 grams of sugar, Or about one-third or one-half spoon of sugar, syrup, or Honey
- 1 gram fat, Or about 5 teaspoons 2% milk, 1 tbsp light cream, or 1 tbsp half and half
Was there To promote any mortality For those who took their coffee With heavy doses of more sugar or milk or creamer.
Interestingly, data has also been shown Normally there is no link between drinking coffee and decrease in cancer mortality. This can happen because the participant pool was on the small side, and the researchers did not see the associations with any specific cancer, Mingyang Song, SCDAssociate Professor of Clinical Epidemiology and Nutrition at Harvard V Chan School of Public Health told Health,
In her own research, Song has found that patients with coffee drinking colorectal cancer had higher survival rates, and other experts have shown that coffee can be done Reduce the risk of colorectal cancer, Overall, however, evidence of other cancer is mixed.
Because Zhang and researchers controlled various demographic factors, Zhang told Health He is confident that the data suggests a reason between coffee additives (or its lack) and a risk of low mortality.
However, the study has some limitations.
Although the data was “informative”, of the study The sample size was limited, It is difficult to understand whether it can catch the link Crossing breed or ethnicity, Lu Qi, MD, PhDProfessor and Director of Obesity Research Center at Tulane University, told Health,
Additionally, most people drank their coffee black-Those who drink their coffee with additives could not be enough participants This is added to paint a whole picture to paint how the mortality can affect the mortality Marilyn Cornelis, PhDA coffee researcher and Associate Professor of Preventive Medicine at Northwestern University Finburg School of Medicine.
Participants are many unknown about drinking actual coffee. Only once or twice habits were assessed for each study participant, and “of the people” Coffee intake may vary Day -day, “The song said.” Some people may consume more coffee during the week. ,
Consumption of coffee of participants may not be stable either during studies.
Researchers also did not take into account all types of coffee or additive. Specific decoction Drinking people could affect the results, as previous research found that unfliered coffee does not reduce the risk of mortality. Also, study Did not see specific types of sweetnessFor example, Chinese vs. low-calorie options- or Compare dairy with non-dairy products.
Each cup of coffee is loaded with more than 100 different molecules and metabolites – one of these groups, polyphenolsCan be largely responsible For many health benefits related to coffee.
Are polyphenols AntioxidantMeaning they help reduce Swelling And eliminate free radicals that will otherwise damage the cells of the body.
So amidst the risk of coffee consumption and low mortality, this relationship is “a biologically admirable”, James O’Kif, MDCardiologist at St. Luke Mid America Heart Institute told Health“Coffee is top Antioxidant source In American diet. ,
Adding more sugar or saturated fat to your coffee Not necessarily get rid of polyphenols Or cancel their effects, the song explained. rather, High consumption of sugar and saturated fat Generally connected to buses Worse heart health results and high mortality.
Since this is the first study to see the effects of coffee additives at mortality risk, Evidence to make certain recommendations is not yet strong enough About this Healthy way to drink coffeeThe song said.
As a general rule of thumb, however, “It is always intelligent Reduce the consumption of sugar and saturated fat, ” He said.
Nevertheless, if you like to add a little cream and sweetener to your coffee in the morning, there is no need to be worried, Cornelis said.
“Black may be better, but you are not at increased risk because you are adding sugar and milk,” he said.
Additives on one side, When it comes to coffee consumption, moderation is important, Zhang and O’Kif insisted, as any health benefits decrease after about two daily cups of coffee. Drink more Can also be dangerous.
“High dose of caffeine can be problematic with WorryIrregular heartbeat, and elevated blood pressure, “O’Kif said.
