Subject: New Protein Study
New study on protein intake that puts a new spin on some fad diets such as Paleo, and Atkins. This is a little long but worth the read.
Researchers at the University of Southern California's Davis School of Gerontology believe high protein consumption in middle age could mean a much higher risk of death from cancer and diabetes. The study followed 6,318 adults from a variety of ethnicities and health histories over two decades and found those with diets high in animal proteins were just as likely to die as a result of cancer as a regular smoker, according to a university release
The USC study defined low-protein diets as those where 10 percent of calories or less come from protein, and high-protein diets as those with 20 percent or more calories coming from protein. But even moderate-protein diets in middle age were shown to result in three times the likelihood of death from cancer.
"The majority of Americans are eating about twice as much proteins as they should, and it seems that the best change would be to lower the daily intake of all proteins but especially animal-derived proteins," Longo said. "But don't get extreme in cutting out protein; you can go from protected to malnourished very quickly."
Longo's findings support recommendations from several leading health agencies to consume about 0.8 grams of protein per kilogram of body weight every day in middle age. For example, a 130-pound person should eat about 45-50 grams of protein a day, with preference for those derived from plants such as legumes, Longo explains.
The researchers define a "high-protein" diet as deriving at least 20 percent of calories from protein, including both plant-based and animal-based protein. A "moderate" protein diet includes 10-19 percent of calories from protein, and a "low-protein" diet includes less than 10 percent protein.
Even moderate amounts of protein had detrimental effects during middle age, the researchers found. Across all 6,318 adults over the age of 50 in the study, average protein intake was about 16 percent of total daily calories with about two-thirds from animal protein — corresponding to data about national protein consumption. The study sample was representative across ethnicity, education and health background.
People who ate a moderate amount of protein were still three times more likely to die of cancer than those who ate a low-protein diet in middle age, the study shows. Overall, even the small change of decreasing protein intake from moderate levels to low levels reduced likelihood of early death by 21 percent.
The study also pinpointed animal proteins as the culprit behind the 74 percent increased risk of death within the study period, from any cause. Even when controlling the amount of fats and carbs in the participants' diets, high animal protein diets had negative health effects. Animal proteins include things like meats, cheeses, milk, and eggs. Diets high in plant-based proteins, however, including foods like beans, lentils, and nuts, did not have the same dangerous effects as animal proteins.
"The research shows that a low-protein diet in middle age is useful for preventing cancer and overall mortality, through a process that involves regulating IGF-I and possibly insulin levels," study co-author Eileen Crimmins said in a release.
This study interestingly does not contradict the Perlmutter diet we recommend @ the Center. Schedule a nutritional consultation today.

Have you ever noticed or paid close attention to the plastic beverage bottles you buy in a grocery or convenience store?
Drinks such as water, fruit juice, soda, iced teas, smoothies, etc generally come in plastic bottles.
Have you ever wondered what the ‘number in the triangle’ means or stands for?
There is a number stamped in a triangle (see image below) on the bottom of just about every plastic bottle we use, which varies from one to seven. I’ve read in various sources where claims have been made that the particular number represents the recycling process of the plastic, specifically, the amount of times that exact bottle has been recycled, but in reverse order. Well … yes and no … While it does have everything to do with recycling, the number of times an item has been recycled has absolutely nothing to do with that particular number.
That number actually represents the type of plastic which is used in the manufacturing of that particular type of bottle. For example, the number ’5′ is made out of polypropylene (PP) while the number ’1′ is called PET which stands for polyethlyene terephthalate.
The numbers below represent the material (type of plastic) that goes into the making of that specific bottle. This number will be useful for you when sorting through the bottles for recycling, but more importantly, the number will help you to determine which bottle is best for reusing or refilling for your own personal use.
Different types of plastics are sometimes referred to as “resins” and the numeric symbols are known as “Resin ID Codes.”
The following chart represents the ‘Resin ID Codes’ or ‘Plastic Identification Number’(PIN) found on each plastic bottle.
# 1 –> PET ….. polyethlyene terephthalate
# 2 –> HDPE ….. high-density polyethylene
# 3 –> PVC ….. polyvinyl chloride
# 4 –> LDPE ….. low-density polyethylene
# 5 –> PP ….. polypropylene
# 6 –> PS/PS-E ….. polystyrene / expanded polystyrene
# 7 –> OTHER ….. resins or multi-materials
* More details/information, as to what types of containers are used for different products, can be found towards the end of this posted article.
Which plastic water bottles don’t leach chemicals?
Choose your water bottles very carefully in order to prevent chemicals in the plastic from leaching into your water.
Plastic water bottles are very convenient for carting water around when we are on the go, as they don’t break if we drop them. However, it is worth paying attention to the type of plastic your water bottle is made of, to ensure that the chemicals in the plastic do not leach into the water. If you taste plastic, you are drinking it, so get yourself another bottle.
To be certain that you are choosing a bottle that does not leach, check the recycling symbol on your bottle. If it is a #2 HDPE (high density polyethylene), or a #4 LDPE (low density polyethylene), or a #5 PP (polypropylene), your bottle is fine.
The type of plastic bottle in which water is usually sold is usually a #1, and is only recommended for one time use. -Do not refill it- . Better to use a reusable water bottle, and fill it with your own filtered water from home and keep these single-use bottles out of the landfill.
Unfortunately, those fabulous colourful hard plastic lexan bottles made with polycarbonate plastics and identified by the #7 recycling symbol, may leach BPA. Bisphenol A is a xenoestrogen, a known endocrine disruptor, meaning it disturbs the hormonal messaging in our bodies. Synthetic xenoestrogens are linked to breast cancer and uterine cancer in women, decreased testosterone levels in men, and are particularly devastating to babies and young children. BPA has even been linked to insulin resistance and Type 2 Diabetes. Nalgene, the company that manufactures the lexan water bottles also makes #2 HDPE bottles in the same sizes and shapes, so we have a viable alternative.
Unfortunately, most plastic baby bottles and drinking cups are made with plastics containing Bisphenol A. In 2006 Europe banned all products made for children under age 3 containing BPA, and as of Dec. 2006 the city of San Franscisco followed suit. In March 2007 a billion-dollar class action suit was commenced against Gerber, Playtex, Evenflo, Avent, and Dr. Brown’s in Los Angeles superior court for harm done to babies caused by drinking out of baby bottles and sippy cups containing BPA. So, to be certain that your baby is not exposed, use glass bottles.
Check the recycling numbers on all your plastic food containers as well, and gradually move to storing all food in glass or ceramic.
Store water in glass or brass if possible, and out of direct sunlight.

Plastic Container Example Guide
Numbers 1 and 2 are the most commonly accepted recyclable plastics. These items include bottles for water, soft drinks, salad dressing, vegetable oil, milk, juice, detergent and shampoo.
Plastics also can be numbered 3 through 7, and the higher the number, the less likely recycling centers are to take the item. Items with the number 7, for example, are made of miscellaneous plastics and include sunglasses, phones, computer cases and signs.
# 1 – PET: Polyethylene terephthalate ….. Water bottles, carbonated beverages, juices, other soft drinks and oven-ready meal trays.
# 2 – HDPE: High-density polyethylene ….. Bottles for milk, bottled soaps and cleaning liquids.
# 3 – PVC: Polyvinyl chloride ….. Food trays, cling film, mineral water and shampoo.
# 4 – LDPE: Low density polyethylene ….. Carrier bags and bin liners.
# 5 – PP: Polypropylene ….. Margarine tubs, microwaveable meal trays.
# 6 – PS: Polystyrene ….. Yogurt containers, foam trays for meat or fish, hamburger boxes, egg cartons, vending cups, plastic cutlery, protective packaging for electronic goods and toys.
# 7 – Other ….. Any other plastics that do not fall into any of the above categories. An example is melamine, which is often used in plastic plates and cups.
