What Should We Drink? 

Here is a review of reviews on the health effects of tea, coffee, milk, wine, and soda. It is important to consider the totality of peer-reviewed science when making decisions about what to consume. Individual studies may lead to conflicting headlines, so looking at a compilation of studies can provide a better understanding of a topic. Reviews written by industry-affiliated researchers may have biases, while independent reviews tend to provide more accurate information. For example, reviews of secondhand smoke conducted by tobacco industry researchers were 88 times more likely to conclude that it was harmless. It is important to be cautious of conflicts of interest when interpreting research findings. A review of reviews on different beverages found tea and coffee to be protective for various health conditions. Soda, on the other hand, tended to have a deleterious effect on health. Milk studies have also been found to have biases, with industry-funded studies being more favorable to the financial interests of the sponsors. Overall, it is important to consider the source of funding when evaluating research on food and drinks.
