Fish and Heart Health – a Surprising Study

Posted on by


The Women’s Health Initiative Observational Study (WHI-OS), which involved 84,493 females aged 50-79 years old, analyzed data over a 10 year period on the effects of various forms of fish consumption and heart failure. At the start of this study none of the participants had heart disease.

Fish is well known as a food which enhances both physical as well as mental health. Fish oil is also reported to be a mental and physical nutrient which reduces disease development and mental deterioration. In evaluating fish and fish oil it would be natural to expect that positive outcomes would be observed and reported.

The study divided the consumption of baked or broiled fish into frequency catagories of less than 1 time per month; 1-3 times per month; 1-2 times per week; 3-4 times per week and greater than 5 times per week.

The study also observed the consumption of fried fish at the frequencies of less than one serving per month; 1-3 times per month and greater than 1 time per week.

The findings, however, were startling. The weekly consumption of 5 or more serving of baked or broiled dark fish, primarily salmon, mackerel and bluefish, was found to lower the risk of heart failure by an impressive 30%. While the consumption of fried fish, just 1 time or more per week, was associated to be related to a 48% increase in heart failure!

Another surprise within this study is that the assumption that taking omega-3 supplements will be as beneficial as eating fish. The study could not identify any significant change in cardiac failure rates that was associated with taking omega-3 supplements.

While the study came to no hard and fast conclusion of why the fried fish was so lethal, the thinking is that there must be some property to the oil when deep fried that creates the negative health affects. Another conclusion was that it appears better to eat fresh fish that is baked or broiled that to reply on fish oil supplements for heart health.

While this is a blow to those of us who love fish and chips, enjoying fish that is well cooked and healthy of our hearts is not a hard thing to get used to.

With all good wishes,

Bisphenol A (BPA) Hidden in Your Food

Posted on by



Most of us are aware that there are lots of dangerous materials like additives, dyes, pesticides and carcinogens in our foods. What many of us are not aware of is that in the containers that our foods come in, especially take out, there are chemicals in the materials that may be even more harmful than the additives, dyes and pesticides.

By now you have probably heard of the dangers of the toxic chemical Bisphenol A (BPA). This chemical can be found in polycarbonate plastic food containers, bottles and takeout food containers. Numerous articles have been written on breast cancer and prostate cancer that result from exposure to the BPA contained in packaging and containers that carry food stuffs.

Recent, important environmental health study findings were published in March in the online journal Environmental Health Perspectives. A study was conducted by two organizations concerned with the environmental causes of breast cancer, the Breast Cancer Fund and Silent Spring Institute. The study was on the dangers of BPA.

The organizations identified and followed five (5) families who frequently used packaged food and drinks which were made for microwave preparation. The BPA levels of these families, which both consisted of a mother, father and two children, were measured and recorded.

Then, these same families ate fresh, organic food cooked only in glass or stainless steel containers. The immediate results on the level of BPA in their bodies with  the packaged food and fresh food was measured via urine collection, at varied intervals of the testing.

The outcomes were significant with all participants having lowered BPA levels in 72 hour period after the BPA rich packaging was exchanged with glass and stainless steel containers. The average decrease in the BPA was approximately 60%.

The study demonstrated that as quickly as six (6) hours after exposure, half the BPA is eliminated through the urine. However, if the prior use of the BPA rich packaging is resumed, the BPA levels demonstrate a return to the pre-intervention level on urine analysis. When the families resumed their normal diets, their BPA levels returned to pre-intervention levels by the next urine sample. 

What is important about this study is that it demonstrates that we can easily reduce the levels of BPA our bodies are exposed to by eliminating the use of the packaging it is found in and by cooking and preparing our foods more naturally. It is important not to use these BPA rich containers to microwave in as this increases the amount of BPA exposure.

Using glass or ceramic containers in the microwave is healthier and most importantly, they contain no BPA.  By also avoiding canned foods (unless the cans are BPA free) you will cut down on this dangerous exposure for both you and your family.
