What You Really Need To Check When Using Plastic Containers

What You Really Need To Check When Using Plastic Containers

Our daily lives are filled with plastic, from tupperware to water bottles. Some plastic containers are safe for human consumption while others are potentially hazardous to your health.

Take a look around your kitchen. Are you sure your plastic is safe and non-toxic? To avoid risking your health, make sure to be familiar with the different types of plastic on the market today.

A simple glance, usually at the bottom of the container, is all you need to identify the material. Plastic is marked with a number, 1 through 7, and/or a set of letters that label its chemical composition. Like this:

    Take a look below to find out what each one means.

    Type 1: PETE or PET

    PET plastic is clear, 100% recyclable, and most commonly used for drinks, mouthwash, and microwavable meal trays. In general, this plastic is considered safe for food and drink storage, although consumers should take some precautions.

    It should be stored at room temperature. High temperatures can increase the levels of the chemical antimony, which is a potentially carcinogenic material. The rule of thumb with this plastic is to only use it once, as reuse can lead to bacterial build-up.

    Type 2: HDPE or HDP

    HDPE plastic is slightly harder than PET and has a very high strength-to-density ratio. Type 2 plastic is not transparent and has dye added for marketing purposes, which means it can come in many different colors. It is used to manufacture detergent bottles, milk jugs, and freezer bags. So far, experts have not found toxic chemicals in its composition. HDPE is not likely to leach into liquids, making it safe for food and drink storage.

    Type 3: PVC or 3V

    PVC plastic is potentially harmful to human health. It is used to make plastic cling wrap as well as some toys for children and pets. Type 3 plastic contains phthalates that may be related to reproductive complications in humans and animals due to chemicals that can affect hormonal production. These chemicals can easily leach into lipid-containing substances and have also been linked to asthma in children.

    Type 4: LDPE

    LDPE plastic is flexible and solvent-resistant. Often used in frozen food, bread, and garbage bags as well as squeezable condiment bottles, it is not known to leach chemicals into food. It can also be found in the lining of paper milk cartons. Its production is considered hazardous but its use is considered low hazard. Many people feel more comfortable avoiding it.

    Type 5: PP

    PP plastic is harder than other plastics and semi-transparent. Common uses for this plastic include yogurt bottles, medicine containers, and margarine and butter tubs. This plastic can be placed in the microwave and reach high temperatures without melting. This means PP plastic containers do not risk leaching into their contents and are therefore safe for storing foods and drinks for human consumption.

    Type 6: PS

    Polystyrene, or PS, plastic is used in foam insulation, egg cartons, styrofoam drinking cups, and take-out containers.

    Advertising

    Avoid using styrofoam materials for food and drink. This plastic is not safe when heated and does leach carcinogenic chemicals into food. Specifically, styrene can contaminate the contents. Styrene has been linked to an increased risk of lymphoma and leukemia. It has also been linked to lung tumors in lab animals. Even hot water and coffee served in styrofoam cups has been found to have increased levels of styrene. This plastic should not be utilized for long-term storage.

    Type 7: PC or Non-Labeled

    PC, Type 7, or any non-labeled plastic should be avoided whenever possible. This category is used to describe packages made of chemicals and resins that are not found in the previous six types of plastic. It is a hard, nearly unbreakable plastic. Polycarbonates contain bisphenol A (BPA) which leaches into container contents. Despite its dangers, it is often used for sports bottles, baby bottles, and water cooler bottles.

    Read Labels!

    Before purchasing any plastics, try to read the numbers and/or letters stamped on the bottom of the container. Try to avoid numbers 3, 6, and 7. Be careful with all plastic containers and don’t let them overheat or store food for too long. Glass containers are preferable.

    12 Best Foods That Improve Memory and Brain Health

    12 Best Foods That Improve Memory and Brain Health

    Nutrition plays a vital role in brain function and staying sharp into the golden years. Personally, my husband is going through medical school, which is like a daily mental marathon. Like any good wife, I am always looking for things that will boost his memory fortitude so he does his best in school.

    But you don’t have to be a med student to appreciate better brainiac brilliance. If you combine certain foods with good hydration, proper sleep and exercise, you may just rival Einstein and have a great memory in no time.

    I’m going to reveal the list of foods coming out of the kitchen that can improve your memory and make you smarter.

    Here are 12 best brain foods that improve memory and brain power:

    1. Nuts

    The American Journal of Epidemiology published a study linking higher intakes of vitamin E with the prevention on cognitive decline.[1]

    Nuts like walnuts and almonds (along with other great foods like avocados) are a great source of vitamin E.

    Cashews and sunflower seeds also contain an amino acid that reduces stress by boosting serotonin levels.

    Walnuts even resemble the brain, just in case you forget the correlation, and are a great source of omega 3 fatty acids, which also improve your mental magnitude.

    2. Blueberries

    Shown in studies at Tuffs University to benefit both short-term memory and coordination, blueberries pack quite a punch in a tiny blue package.[2]

    When compared to other fruits and veggies, blueberries were found to have the highest amount of antioxidants (especially flavonoids), but strawberries, raspberries, and blackberries are also full of brain benefits.

    3. Tomatoes

    Tomatoes are packed full of the antioxidant lycopene, which has shown to help protect against free-radical damage most notably seen in dementia patients.

    4. Broccoli

    While all green veggies are important and rich in antioxidants and vitamin C, broccoli is a superfood even among these healthy choices.

    Since your brain uses so much fuel (it’s only 3% of your body weight but uses up to 17% of your energy), it is more vulnerable to free-radical damage and antioxidants help eliminate this threat.

    Broccoli is packed full of antioxidants, is well-known as a powerful cancer fighter and is also full of vitamin K, which is known to enhance cognitive function.

    5. Foods Rich in Essential Fatty Acids

    Your brain is the fattest organ (not counting the skin) in the human body, and is composed of 60% fat. That means that your brain needs essential fatty acids like DHA and EPA to repair and build up synapses associated with memory.

    The body does not naturally produce essential fatty acids so we must get them in our diet.

    Eggs, flax, and oily fish like salmon, sardines, mackerel and herring are great natural sources of these powerful fatty acids. Eggs also contain choline, which is a necessary building block for the neurotransmitter acetylcholine, to help you recall information and concentrate.

    6. Soy

    Soy, along with many other whole foods mentioned here, are full of proteins that trigger neurotransmitters associated with memory.

    Soy protein isolate is a concentrated form of the protein that can be found in powder, liquid, or supplement form.

    Soy is valuable for improving memory and mental flexibility, so pour soy milk over your cereal and enjoy the benefits.

    7. Dark Chocolate

    When it comes to chocolate, the darker the better. Try to aim for at least 70% cocoa. This yummy desert is rich in flavanol antioxidants which increase blood flow to the brain and shield brain cells from aging.

    8. Foods Rich in Vitamins: B vitamins, Folic Acid, Iron

    Some great foods to obtain brain-boosting B vitamins, folic acid and iron are kale, chard, spinach and other dark leafy greens.

    B6, B12 and folic acid can reduce levels of homocysteine in the blood. Homocysteine increases are found in patients with cognitive impairment like Alzheimer’s, and high risk of stroke.

    Studies showed when a group of elderly patients with mild cognitive impairment were given high doses of B6, B12, and folic acid, there was significant reduction in brain shrinkage compared to a similar placebo group.[3]

    Other sources of B vitamins are liver, eggs, soybeans, lentils and green beans. Iron also helps accelerate brain function by carrying oxygen. If your brain doesn’t get enough oxygen, it can slow down and people can experience difficulty concentrating, diminished intellect, and a shorter attention span.

    To get more iron in your diet, eat lean meats, beans, and iron-fortified cereals. Vitamin C helps in iron absorption, so don’t forget the fruits!

    9. Foods Rich in Zinc

    Zinc has constantly demonstrated its importance as a powerful nutrient in memory building and thinking. This mineral regulates communications between neurons and the hippocampus.

    Zinc is deposited within nerve cells, with the highest concentrations found in the hippocampus, the part of the brain responsible for higher learning function and memory.

    Some great sources of zinc are pumpkin seeds, liver, nuts, and peas.

    10. Gingko Biloba

    This herb has been utilized for centuries in eastern culture and is best known for its memory boosting brawn.

    It can increase blood flow in the brain by dilating vessels, increasing oxygen supply and removing free radicals.

    However, don’t expect results overnight: this may take a few weeks to build up in your system before you see improvements.

    11. Green and Black Tea

    Studies have shown that both green and black tea prevent the breakdown of acetylcholine—a key chemical involved in memory and lacking in Alzheimer’s patients.

    Both teas appear to have the same affect on Alzheimer’s disease as many drugs utilized to combat the illness, but green tea wins out as its affects last a full week versus black tea which only lasts the day.

    12. Sage and Rosemary

    Both of these powerful herbs have been shown to increase memory and mental clarity, and alleviate mental fatigue in studies.

    Try to enjoy these savory herbs in your favorite dishes.

    When it comes to mental magnitude, eating smart can really make you smarter. Try to implement more of these readily available nutrients and see just how brainy you can be!
