Processed meat may pose health risks, including heart disease, diabetes, and colon cancer. High levels of sodium and nitrates are possible reasons. Some people make their own processed meat to reduce risks. Skepticism exists due to difficulties in studying diets and research methods used. Human error may also affect study results.
There is a growing consensus that eating too much processed meat can be unhealthy, but there is also a lot of skepticism about these opinions and no certainty on the matter. There have been several studies suggesting that consuming products like sausage, salami, bacon, and other processed meats might pose some health risks. These include a possible association with heart disease, diabetes, and a potential association with colon cancers. Some experts question the quality of the research methods behind these studies, partly because of the inherent difficulties in studying people’s diets and partly because of some of the research methods used.
Experts believe there are a few different possible reasons why processed meat could be more dangerous to a person’s health than fresh meat. One possibility is the higher levels of sodium often found in processed meat products. Salt is often used to help preserve things, and significant amounts are often added to many processed foods. Some studies already suggest a possible connection between sodium and high blood pressure, so this could be one of the main reasons. Another possibility is the inclusion of chemicals called nitrates, which are typically also included for conservation purposes.
Some people have responded to these studies by making an effort to create their own processed meats at home. In these cases, people will often reduce the amounts of salt or at least minimize the use of other chemicals. These people believe that taking these measures could allow them to eat cured meats, sausages and other processed foods without exposing themselves to as many dangers. The actual effectiveness of this approach has generally not been studied very extensively.
There is a certain level of skepticism about some of the studies that are fueling concerns about processed meat products. Some skeptical scientists think the research may show a false connection, and this can happen in a number of ways. For example, if most of the people who ate large amounts of sausage also had some other lifestyle element in common, such as a lack of exercise, it might be difficult to determine what actually caused the association. Studies usually make an effort to adjust for these possibilities, but things can occasionally creep in anyway, especially when the results are statistically marginal.
Another possible problem with many food studies is the time it takes to do them and the difficulty of participating. Many studies simply ask people to follow a diet for a specific amount of time or give them a survey of what types of foods they ate. Because many of these studies aren’t necessarily supervised, there is often a human element at play, and people may forgo diets during the study or forget details when answering surveys.
