Dangerous Plastics

1) Polyvinyl chloride (PVC) is used in a wide range of consumer products, including Reynolds Wrap and cling wrap for most grocery stores, as well as bottles, packaged food trays and cooking oil bottles. PVC is also used for plumbing materials, as well as medical tubing and bags.

Reason to Avoid: Polyvinyl Chloride (PVC) contains phthalates, which are known to disrupt hormones — especially testosterone. Congress has banned the use of these chemicals in toys because of research that indicates developmental and reproductive damage. Vinyl chloride is a known human carcinogen. Additionally, the manufacture and incineration of phthalates releases dioxin, a known carcinogen and hormone disruptor.

2) Polystyrene (PS) is one of the most widely used plastics. There are two forms of polystyrene — inflated and non-inflated. The most recognizable inflated polystyrene is Styrofoam®, a Dow Chemical Company trademarked product. Non-inflated polystyrene is used to make cups, bowls, plates, trays, cutlery, take-out containers, meat trays and egg cartons, as well as packaging for shipping.

Reason to Avoid: This type of plastic can leach styrene into food, especially when heated. Styrene is classified as a possible human carcinogen by the EPA and by the International Agency for Research on Cancer.

3) Polycarbonates (PC). Polycarbonates are used in many brands of plastic baby bottles, “sippy” cups for kids, reusable water bottles and dental sealants. Also used in the inner lining of food cans.

Reason to Avoid: Polycarbonate plastic is the only plastic that is made with bisphenol-A (BPA), which has been found to mimic the hormone estrogen and disrupt the body’s endocrine system. Public health advocates say it poses a particular risk to fetuses, infants and children. The National Toxicology Program issued a report last year that includes concerns about BPA’s effects on the brain, prostate gland, mammary gland, and behavior in fetuses, infants and children.

Blood Sugar Stabilization Barrier

After consumption of a carbohydrate-rich meal, your digestive
system breaks down the carbs into tiny glucose molecules.
Once these molecules enter the bloodstream they trigger the release of
insulin by an organ called the pancreas. Insulin ensures that the glucose
is delivered to necessary tissues for energy. When these energy stores are
full any excess glucose still in the bloodstream or digestive tract is easily
converted to fat.

Unfortunately, most of us are walking around with chronically elevated insulin levels because of excess energy consumption, especially
in the form of simple sugars. Constant exposure to high amounts of
insulin results in a condition called “Metabolic Syndrome.”
This condition is characterized by high levels of circulating fats in the
bloodstream, high cholesterol, high blood pressure, uncontrollable
appetite cravings, obesity and increased diabetes risk. Even more
critical is the decreased sensitivity to insulin which means that the
cells become so accustomed to high blood insulin levels that they
grow non-responsive so even more insulin is released!

    Thanks for the info. I definitely was doing better in Feb. than now. I decided to not eat sugary desserts in Feb. and only had something two days out of the month. This month I have had more sugar because we made cookies to take to my kids' awards ceremonies, and my son wanted to make "cookies we use a fork with" or peanut butter cookies. So, we had those around the house. I do better not having homemade goodies around to eat. I have to commit to no sugary desserts again esp. before Easter gets here. emoticon

Free Radical Barrier

The more energy you require the more oxygen you must utilize. Occasionally oxygen can mutate and escape from the cell in the form of a “free radical” or oxidant. When these renegade oxygen molecules combine with other molecules in the body they can interrupt the processes associated with their “host” molecule.

Because they can interact with so many different molecules, free radicals
can wreak serious havoc by altering DNA, destroying sensitive protective
barriers around the cell and changing the fragile biochemical structures
of proteins and fats. These disruptions and alterations of sensitive cellular
processes can sabotage energy production. Even a small amount
of damage to a cell’s outside receptors and membrane can severely alter
the movement of compounds in and out of the cell, eventually killing
the cell.

Food

Energy comes from food. However, complex actions must take place inside your body for turkey, mashed potatoes and cranberries to be-come the energy needed to talk, stand, sit, walk and breathe. Your body must break the food into small pieces, then absorb and move them through the membrane of a tiny cell to be broken into even smaller pieces. These pieces then enter into a miniscule cellular component called the mitochondria. The mitochondria is the cell’s powerhouse. It is here that the electrical power of oxygen is harnessed to
finally break that last tiny molecule of food apart and release energy!

There are thousands of crucial steps leading up to this eventual re-lease of energy, most of which require energy themselves. This energy is derived from the calories, nutrients, vitamins and minerals you’ve previously consumed and are combined with the oxygen you breathe. Any shortage of the necessary components results in a shortage of energy. Therefore, inadequate oxygen or inadequate food intake results in inadequate energy.

Inadequate energy results in a slow metabolism. WE DO NOT WANT THAT!

Bad Breakfast Choices

Ideally we'd be prepared -- but if you're stuck in an all-morning meeting and the only food choice is a pastry, is it better to eat it or skip breakfast?

SKIP IT. There is nothing actually filling about a pastry -- no fiber, no water -- so it wouldn't help my hunger. In fact, many times eating something high in sugar like this will lead to an energy crash, so I wouldn't be full and it makes me tired. No thank you! (I have apples and almonds at my office for situations like this.)


Have a great weekend!

My first 5k for 2013 is tomorrow, WOOHOO!

    I agree. Lucky sweets don't appeal to me very often.
Best of luck to you on your 5K.

    Yum, apples and almonds. I have been eating granny smiths with peanut butter. Love the tart taste mixed with sweet/salty of the peanut butter. I bought raw almonds with my hubby the other day 5 pounds and then discovered we had 2 (5) pounds bags in the freezer in the garage.....looks like we have enough for a very long time. :)
