Red Meat and healthy life
Red meat is rich of protein , but also high in unhealthy saturated fat, its should be eaten sparingly.
The balance of good health recommends that you should eat at
least two servings per day from the protein group, which
includes red meat. Many people, however, eat a great deal more
meat than this. Some studies show that people who eat large
quantities of read meat on a daily basis have a higher incidence
of cardiovascular disease than those who eat it less often.
The relationship between red meat and cardiovascular disease is believed to be due to the high saturated fat and cholesterol content of these meats. Have a evidence to suggest that a high intake of read meat increase your risk of colon cancer. People who replace red meat with fish and chicken have been found to have lowered their risk of cardiovascular disease and colon cancer. So, is it a good idea to choose to eat lower fat sources of protein. Processed meat was mostly pork and beef that were preserved by methods other than freezing. They include ham, bacon, sausages, liver pate, salami, tinned meat, luncheon meat and corned beef.
Types of meats
Games, such as venison, wild boar, rabbit and more recently, buffalo, has meat that is rich and full of flavour, because this animals get more exercise, their meat is leaner and lower in fat than beef, lamb and pork, and thus also lower in calories.
Offal: kidney, liver, tongue, sweetbreads, trotters and so on are nutritious meats, being a good source of many of the B vitamins as well as vitamins A and D and the mineral copper, iron and zinc. As liver can tend to accumulate chemical residues from the animal, so better to eat only the liver of young animals, such as calves and lambs. You should try to avoid eating too many preserved meats, such as bacon, ham, pancetta, sausages, salami and gammon because they often contain a lot of salt as well as being high in saturated fat. Many cured meats also contain high levels of preservatives.
Which meat is good for healthy life?
If you like beef and lamb, start by choosing cuts that have a
low fat contain (right) and reserve the higher
fat cuts for
special occasions like ones or twice a month. Check any
labeling on meat at the
supermarket, some labels will give the fat content, particularly
labels on on packets of minced or ground beef. The leanest
types of red meat are beef topside, rump and filet fillet steak,
pork leg and lion steak, and game such as venison. Remember to
trim off visible fat before cooking. Red meat is high in fat,
particularly when compared to the white meat of poultry-very
lean red meat (such as fillet steak) has a lower fat and calorie
content than roast dark meat chicken (legs and wings) eaten with
the skin.

Healthy life with red meat
Regardless, nutritionists hardly need more evidence about the potentially negative health effects of eating red meat. For starters, the saturated animal fat in red meat contributes to heart disease and atherosclerosis. Recent research also shows that frequent red meat eaters face twice the risk of colon cancer as those who indulge less often. Red meat is also thought to increase the risks of rheumatoid arthritis and endometriosis. Red meat consumption is associated with cardiovascular diseases, possibly because of its high content of saturated fat.
Over 10 years, eating the equivalent of a quarter-pound
hamburger daily gave men in the study a 22 percent higher risk
of dying of cancer and a 27 percent higher risk of dying of
heart disease. That's compared to those who ate the least red
meat, just 5 ounces per week.
Women who ate large amounts of red meat had a 20 percent higher
risk of dying of cancer and a 50 percent higher risk of dying of
heart disease than women who ate less.
For processed meats, the increased risks for large quantities
were slightly lower overall than for red meat. The researchers
compared deaths in the people with the highest intakes to deaths
in people with the lowest to calculate the increased risk.
People whose diets contained more white meat like chicken and
fish had lower risks of death.
The researchers surveyed more than 545,000 people, ages 50 to 71
years old, on their eating habits, then followed them for 10
years. There were more than 70,000 deaths during that time.
A major study has found fresh evidence linking eating red and processed meat and bowel cancer. The risk was a third higher for those who regularly ate over two 80g portions of red or processed meat a day, compared to less than one a week. The study also found a low fibre diet increased the risk of bowel cancer. Eating poultry had no impact but the risk for people who ate one portion or more of fish every other day was nearly a third lower than those who ate fish less than once a week.
Eating cooked red meat may increase the likelihood of cancer because carcinogenic compounds called heterocyclic amines are created during the cooking process. Heterocyclic amines may not explain why red meat is more harmful than other meat, however, as these compounds are also found in poultry and fish, which have not been linked to an increased cancer risk.
The study shows that after an average of almost five years,
people who ate the most red meat and processed meat had a 35
percent greater risk of developing colorectal cancer than those
who ate the
least amounts.
The cancer risk actually rises with fairly small amounts of
these foods. Eating more than about five-and-a-half ounces of
red meat and processed meat per day put people in the most
at-risk group. A smaller change in risk was even seen with 10
ounces per week. The meats responsible include beef, pork, lamb
and veal, plus sausage, ham, bacon and cold cuts.
There are several factors to consider when trying to discern how red meat raises cancer risk. The high saturated fat content is a major contributor to heart disease. It may affect cancer development as well. But merely choosing lean red meats and reduced-fat processed meats does not appear to remove the cancer risk.
The traditional food guide pyramid
has been criticized for not distinguishing between red meat and
other
types of meat. The newer My Pyramid recommends lean forms
of red meat. The healthy eating
pyramid recommends that red meat be consumed sparingly. Red
meat is one of the richest sources of iron. Red meat also
contains protein, levels of creatine, minerals such as zinc and
phosphorus, and vitamins such as niacin,
vitamin B12, thiamin
and riboflavin. Red meat is the richest source of Alpha Lipoic
Acid, a powerful antioxidant.
If you continue to include red meat in your diet, choose lean cuts and stick to the recommend 3 ounces or less a day. Even if you’ve eaten large amounts of red meat your entire life, studies suggest that changing your eating pattern now can have a positive effect within a few years.
Some experts believe the trouble might
come from the iron and fat in the meats, others blame the salt,
nitrates/nitrites of processed meats.
Not only that, when meat is cooked (especially fried or
charbroiled) at high temperatures substances are created that
can be mutagenic or even carcinogenic. In other words - trouble.
Most experts suggest that meat should not be eliminated entirely
from your diet, but rather become a supporting part of meals
along with other healthy options. Choose fish, poultry or
beans as an alternative to the red meats. Leaner cuts can also
be part of a healthy diet.
Healthy ways with red meat
Rather than trying to eliminate red meat from your diet completely, the solution is to eat it less often and to select the leanest cuts possible. Minimize the fat content of meat by adopting healthy preparation and cooking methods.
If you have risk factors for heart disease or cancer, you'll want to talk to your own doctor to find out what diet and lifestyle changes you can make to today to help keep your body healthy and disease free. Don't let the link between red meat and health be your downfall.
Food Additives and healthy life
Sweeteners
In addition to adding sweetness, sugar's distinctive
properties enable it to play an important role in food
preservation. Have many sweeteners like calorie-free and
sugar alcohols (polyols) are used by food manufactures in their
products.

Fruits and healthy life
Dried fruits
When fruits is dried or dehydrated, most of the nutrients are
concentrated in the remaining solids. This is why the dried
fruits have more nutrients and more calories by weight than
fresh fruits. Some light coloured dried fruits like apples,
apricots, peaches pears and sultans are treated with sulphur-based
preservatives to prevent discoloration.
