Smoking preserves meat and fish both by slow cooking at a low temperature and by treatment with chemicals in the smoke
The method is now used primarily for flavor—for example, the distinctive hickory or oak aroma that is associated with smoked bacon, and the mesquite and other aromatic wood chips that are used to enhance the taste of grilled foods
Air curing, or preserving by dehydration, has been used for thousands of years
Prosciutto is an air- cured meat
Drying generally concentrates some nutrients, especially minerals, but the vitamin content of dried meat is much less than that of fresh
Salt-cured meats, such as country ham or bacon, are preserved either in a brine solution or a dry salt bed
The salt draws water from the meat and from bacteria and molds through the process of osmosis
While the meat remains wholesome, the microorganisms shrivel and die

limit for the amount of fat in fresh pork sausages
Link sausages are typically made from pork or beef with cereal fillers, herbs and spices, and preservatives
Because sausages go through several stages of handling, they are more susceptible to contamination than fresh meat and should be cooked very thoroughly before consumption
The term cold cuts technically refers to any cooked meats that are sliced and served cold, but it is frequently also used to refer to cured and smoked meats
All cold cuts and cured and smoked meats are high in sodium, frequently more than 30% of RDA
Many, especially cold cuts and sausages, also contain fillers such as corn syrup or cereal (and therefore should be avoided by people with celiac disease or gluten intolerance)
Some, especially those made from pork or beef, are also high in saturated fats; turkey or chicken versions usually have lower levels of fat
Health Benefits
Can boost muscle growthSeveral cold cut options are loaded with protein, which is essential to building and repairing muscles
Opt for cuts that are low-sodium and for lean, low-fat meats, such as turkey breast
Health Risks
CancerThe reddish-pink color of cured meats, including the cold cuts at the deli counter, is due to the presence of nitrites, chemicals that enhance the effect of salt by inhibiting bacterial growth and slowing fat oxidation
Nitrites can cause tumors in laboratory animals that consume it in very high doses
But the meat industry and the government insist that nitrites should be retained because they are extremely effective against Clostridium botulinum, the microorganism that causes botulin poisoning, or botulism
WARNING
!FOOD-DRUG INTERACTION
The amino acid tyrosine, which is found at high concentrations in cured meats, can cause migraines, an abrupt rise in blood pressure, and even fatal collapse in persons taking monoamine oxidase (MAO) inhibitors to treat depressionHigh blood pressure and cardiovascular disease
Because of their high sodium content, cold cuts and other cured meats can increase blood pressure, a leading risk for heart problems
Migraines
Tyramine, a metabolic product of the amino acid tyrosine, is found at high concentrations in cured meats
It can trigger migraine attacks in susceptible people
Listeriosis and toxoplasmosis
Listeria, a bacteria found in deli meats, infects an estimated 2,500 people per year with listeriosis, which causes flulike symptoms
The bacterium is killed by the pasteurization process and cooking; but some deli foods are contaminated after processing
While the infection is rarely serious for healthy adults, pregnant women should limit the amount of cold cuts they eat because it poses a serious risk to the baby
Uncooked air-cured or salt-cured meats may be infected with the toxoplasmosis parasite, which can have similar risks for fetuses

s
But “lower” doesn’t mean much— some brands still top 460 g of sodium per serving in their lower-sodium versions
