Cured meats linked to exacerbated respiratory illness symptoms: study

AFP Relax

Eating too much cured meats like salami, chorizo and bacon can worsen symptoms of respiratory diseases like emphysema and chronic bronchitis and lead to a trip to the hospital, says a new study.

Published in the European Respiratory Journal last week, a team of Spanish researchers say they've found a link between the consumption of cured meats and the increased number of hospital admissions among people suffering from chronic pulmonary disease (COPD).

The umbrella term is used for a number of respiratory illnesses caused by inflammation in the lungs.

For their study, researchers worked with 274 COPD patients from their first hospital admission and monitored them for the next two years. Participants also provided information on their cured meat consumption.

Their conclusion? People who eat large quantities of cured meats -- identified as more than a slice of ham or equivalent a day -- were more likely to experience exacerbated symptoms and be admitted to hospital.

Researchers believe the problem lies in the nitrites which act as preservatives and anti-bacterial agents in the meats -- substances which have also been shown to cause a reaction and damage tissue in the lungs.

While previous research has shown that increased consumption of cured meats like hot dogs and salami can lead to an increased risk of developing COPD, the Spanish researchers say theirs is the first to show that eating processed meats can also inflame and worsen symptoms.

Processed and cured red meats, which are high in sodium and nitrites, have also been linked to the development of Type 2 diabetes, heart disease and bowel cancer.

The health benefits of antioxidants

RealBuzz 


The process in which oxygen combines with another material is called oxidation. For instance, unprotected iron will turn to rust when oxidized, fruits will turn brown, and butter will become rancid. A similar process occurs in the body causing it to degenerate and age, and as we get older more oxidation occurs in the body.
When our cells are exposed to free radicals, this process of oxidisation occurs. Therefore, our aging process depends on our ability to protect our cells from oxidation. However, this is no easy task; we are exposed to free radicals every day, introduced to the body from toxic chemicals that are either breathed in or absorbed through the skin.
The body’s oxidative reaction occurs due to the exposure to environmental toxins that are present in the air we breathe, the water we drink, the food we eat and the household products we use. And it is these ‘free radicals’ that contribute to the oxidative reactions in the body and cause tissues to damage and can also affect memory and mood, wrinkling of the skin, hardening of the arteries, stiffening joints — the list goes on.
Exposure to environmental toxins dramatically increases the level of free radicals in the body, sometimes beyond what our body can fight on its own. The human body is capable of handling and neutralising a certain amount, but when the system is overloaded the body’s normal ability to cope with them is compromised and become susceptible to premature aging and disease.

Free radicals can be found in the following:

  • Junk food
  • Refined foods, such as sugar and white flour
  • Processed foods (canned, frozen and ready made meals)
  • Colourings, preservatives and food additives
  • Chemotherapy or radiation exposure (X-rays, TV and computer monitors)
  • Drugs and medications
  • Coffee and tea
  • Hydrogenated and saturated fat (margarine and oils)
  • Fizzy drinks
  • Exposure to heat or cold
  • Household chemicals
  • Tap water
  • Cigarette smoke and alcohol

Natural antioxidants

Fortunately there are nutritional approaches to protect the body from free radical damage. Antioxidants are powerful nutrients that have shown to be efficient in minimizing the effects of free radicals. Antioxidants are nature’s free radical fighters and occur naturally in plant foods. Therefore, if we are not getting enough variety and quantity of antioxidants, these toxic chemicals will destroy cells leaving the body vulnerable to disease.
The body needs plenty of antioxidants to help destroy free radicals, to promote the growth of healthy cells and protect these cells against premature aging. Much of the damage can be repaired in a short amount of time by simply providing the brain and body with repeated doses of antioxidants. Eating fruits and vegetables at optimal ripeness and consuming them in less processed forms without removing their skins, provides quality antioxidants.
Organic produce is high in antioxidants as well as being rich in flavor and full in nutrients. It is worth remembering that no matter how healthy your lifestyle is, you will be exposed to free radicals. Therefore antioxidant-rich foods are a must to your everyday diet. To help protect your body, nature has provided us with a wide range of different antioxidants. They are found in fruits, vegetables, whole grains and seeds, beans and many other natural foods. The more antioxidants the body gets, the better it is able to adapt to stress.
Antioxidants can be found in the following foods:
  • Whole and unrefined foods
  • Natural plants (fresh fruits, vegetables, herbs, whole grains, beans, raw nuts and seeds)
  • Raw foods
  • Cold-pressed oils (olive, canola and flax)
  • Seaweeds
  • Sprouts
  • Free-range meat and eggs

Nutrients that reduce free radical damage

The best sources of antioxidants to fight free radicals are rich in vitamins C, E and vitamins B, flavonoid and beta-carotene. Below is a quick guide to foods that are high in these nutrients, and therefore packed with antioxidants:
  • Berries (cranberries, blackberries, blueberries) and citrus fruits are potent antioxidants that promote collagen and reduce wrinkles keeping the skin looking young.
  • Carrots and apricots protect the skin against sun’s ray damage.
  • Green leaves, vegetables, apples, oranges, cherries, beets, carrots, artichokes and strawberries are rich in the minerals copper, magnesium, and selenium; all needed for healthy hair, nails and bones.
  • Bee pollen, royal jelly and bee propolis are complete foods. These powerful antioxidants contain 22 amino acids and vitamins D, K and E, carbohydrates and proteins. A human body can survive on bee pollen alone. This is an energy booster and can help alleviate allergy symptoms.
  • Lycium fruits and liquorice flavonoids are high antioxidants which help counteract effect of chemotherapy and radiography (radiation).
  • Aloe Vera raw gel (cold-pressed only) contains an abundance of 75 minerals and vitamins including the rare B12 and 12 amino acids which help with digestive and skin disorders. Aloe Vera is a miracle plant and a natural healer.
  • Raw nuts and seeds, dark fish, seaweed and avocado are rich in EFA, omega-3, alpha- linoleic acid and selenium. These foods can influence against premature aging and enhance your memory.
  • Chestnuts, papayas, sprouts, squash, sweet potatoes, kiwi, broccoli, cabbage, spinach can help detoxify the liver.
European studies have found that high intake of flavonoid from vegetables and fruits are related to low heart disease and cancer.
Many of these foods improve the functioning of the immune system. When the body is healthy it can cope with free radicals as it has a mechanism into place to ensure their destruction. To achieve a healthy complexion eat plenty of raw food and drink lots of water. What goes into your body reflects your overall appearance!

5 Confusing Food Labels


By Lucy Danziger and the staff at SELF

These days, it seems like almost every packaged good you pick up has a label touting the food's body benefits: heart-healthy! cholesterol-free! But some health claims are more hype than anything else, resulting in labels that are confusing, redundant and just plain silly. To help you spend your grocery money wisely, we had experts puzzle out the promises.

The sell: “Gluten-free” seeds

All seeds are naturally gluten-free, say self contributing experts Stephanie Clarke, R.D., and Willow Jarosh, R.D. Gluten is a portion of a protein found in certain grains like wheat. Some marketers may be trying to capitalize on the popularity of no-gluten diets for weight loss (which don't necessarily work, BTW). Bottom line Don't mistake gluten-free for diet-friendly: The term doesn't mean seeds—or any food—are less fattening.

The sell: “Cholesterol-free” corn oil

Duh alert! Any plant-based food has zero cholesterol. The only place you'll find cholesterol is in animal products, because it comes from the membranes of animal cells. Unless a living creature was involved (as with cheese), the food is cholesterol-free. Bottom line Yes, corn oil is cholesterol-free, but so are olive and peanut oils. And walnut and grapeseed oils. Choose based on your intended use (corn oil for cooking, olive for salad dressing).

The sell: “Real cheese”

Um, as opposed to what? Sadly, there are dairy-free soy imitations that look like true cheese, including the shredded stuff on some pizzas. Foods with the REAL seal must be made with actual dairy, but they can also have unsavory ingredients such as added preservatives and colors (e.g., taxicab yellow). Bottom line You can't count on front-of-the-box labels to avoid processed junk. Look for red flag words like cheese product.

The sell: “Promotes respiratory health”

This tea heralds wellness perks in big type, but the fine print reveals that the FDA hasn't evaluated the claim and the product doesn't treat illness. Companies can legally get away with making health-related pledges by using weaker words (support, promote) versus authoritative ones (prevent, protect). Bottom line No single food is a cure-all for sickness. If you're under the weather, visit your doctor—you may need a real Rx.

The sell: “All-natural” carrots

Natural foods are flying off shelves; it's little wonder the label is everywhere, even on foods that clearly came from the ground. The term, however, is toothless, Clarke and Jarosh say. The FDA hasn't defined natural and doesn't regulate its use, so companies can—and do—use it willy-nilly to up sales. Bottom line Don't let an “I'm natural” pickup line charm you into opening your wallet. Check ingredients to decide on a buy.
