Is our polycarbonate water bottle safe?

Our PolyCarbonate Water Bottle - A close look at the facts

Is the hype around the ‘dangers’ of Polycarbonate Bottle use based on Fact?


Polycarbonate plastic is a lightweight, high-performance plastic that possesses a unique balance of toughness, dimensional stability, optical clarity, high heat resistance and excellent electrical resistance. Because of these attributes, polycarbonate is used in a wide variety of common products including digital media (e.g. CDs, DVDs), electronic equipment, automobiles, construction glazing, sports safety equipment and medical devices. The durability, shatter-resistance and heat-resistance of polycarbonate also make it an ideal choice for tableware as well as reusable bottles and food storage containers that can be conveniently used in the refrigerator and microwave (APME).

Bisphenol A (BPA) is a key building block of polycarbonate plastic. In recent years a number of researchers from government agencies, academia and industry worldwide have studied the potential for low levels of BPA to migrate from polycarbonate products into foods and beverages. These studies consistently show that the potential migration of BPA into food is extremely low, generally less than 5 parts per billion, under conditions typical for uses of polycarbonate products.

Should you drink Reverse Osmosis water?

The principle of drinking ‘Pure’ water as suggested by the RO proponents is that plain H2O is the purest form of water, and often they cite the evaporated rainwater as an example.

While this may sound logical, a cursory glance at this diagram of the Water Cycle very quickly dispels that theory, simply because our normal and natural method of getting water from rain goes through one very important process before we get to drink it; it runs down the mountainside and comes into contact with rocks, soil and plants and absorbs essential nutrients.

Does this principle hold true for RO water?

This same question was researched in 2004, commissioned by WHO (World Health Organisation) and quotations from those findings tell a very different story.

Questions from clients: Tryptophan supplementation and Mindset

Recently we received an enquiry regarding supplementing Mindset with tryptophan:

Hi, Can I use tryptophan and your Mindset product together ?

In essence there is no problem using Tryptophan with Mindset.

However perhaps some food for thought is the following:

At Sevenpointfive we have always followed the reasoning that separating singular nutrients tends to go against natural food pathways and in most instances cause more imbalance than benefit. As an illustration consider the Supplement you are referring to, where, if not specifically taken in combination with other nutrients, it becomes less than useful or even useless.

Cancer Survival - Vitamin D link

Patients diagnosed with colon cancer who had abundant vitamin D in their blood were less likely to die during a follow-up period than those who were deficient in the vitamin, according to a new study by scientists at Dana-Farber Cancer Institute.

The findings of the study — the first to examine the effect of vitamin D among colorectal cancer patients — merit further research, but it is too early to recommend supplements as a part of treatment, say the investigators from Dana-Farber and the Harvard School of Public Health.

The artificial sweetener aspartame is a food ingredient that is perhaps the most controversial of all: Its manufacturers and official bodies claim it’s safe, but a stack of anecdotal evidence and a fair degree of science says it’s not.

Benefits of Coffee - research behind Berriola and ZiNG

Usually we don’t associate coffee with healthy foods. On the contrary, it has a long history of being blamed for many evils, from stunted growth to claims that it causes heart disease and cancer. Recent research, though, indicates that coffee is not the bad boy some make it out to be; in fact, it may be just the opposite. These studies suggest that it doesn’t just give us a boost in the morning; it is a highly beneficial and healthy drink.
