Big Food?

“Robert Goldstein, a hedge fund manager in New York, was getting huge cravings for sweets when he came across a tropical plant called Gymnema sylvestre that works a little like methadone for heroin addicts.” What does that have to do with “big food”? Too much, I’m afraid.

UNHEALTHY PROCESSED FOOD AND SNACKS CAN LEAD TO OBESITY

Cancer, Diet and Lifestyle: What We Know

Cancer, Diet and Lifestyle

Cancer develops by complex processes that are not yet fully understood. It is thought that the risk of development begins when the DNA is damaged possibly by reactive oxygen molecules, toxins, viruses and other reactive substances within cells. This is called the initiation phase. Most of the time, DNA is successfully repaired. When that does not occur, the next phase called promotion occurs where cells with damaged DNA divide into localized areas of the body. This process can occur from 10 to 30 years (“lag time.”). If there is still no repair, the next phase called progression can result with uncontrolled growth and spread of abnormal cells (metastasis) to other parts of the body (lung, liver, breast, bone, prostate, e.g.}.

According to Robert H, Lustig, MD, in his new book, Metabolical: The Lure and Lies of Processed Food, Nutrition, and Modern Medicine, epigenetics plays a strong role in gene expression. “Epigenetics refers to changes in the areas around our genes that can cause them to be turned on or off. Think of it this way: epigenetics is the on-off switch attached to the dimmer in your living room chandelier. The gene is the lightbulb, the epigene is the light switch. If the light bulb is defunct or the switch is frozen in the “off” position, the dimmer function is useless.” This may partly explain whether a disease or its risk is turned on or off. (SJF)

The eight leading environmental factors (other than genetic) related to cancer development are:

Obesity

Low vegetable and fruit intake

Physical inactivity

Smoking

Excess alcohol intake

Unsafe sex

Air pollution

Hepatitis B or C viral infection

DIET MODIFICATIONS

Consume a nutrient dense, whole-foods diet that predominantly includes plant foods. As Michael Pollan puts it, “Eat food, not too much, mostly plants.” Plant foods are rich in nutrients and phytochemicals that work synergistically to prevent many chronic diseases, primarily heart disease and cancer. Evidence exists that up to 45% of colon cancer cases could be avoided through diet and lifestyle changes alone.

Limit your consumption of high-calorie dense foods, primarily in the form of ultra-processed foods that are major contributors to weight gain leading to type 2 diabetes, or insulin resistance.

Cancers of the liver, pancreas, endometrium, colon, rectum, breast, and bladder are at higher risks for developing in obesity. Being overweight also raises the risk of developing non-Hodgkin’s lymphoma, multiple myeloma and gallbladder, liver, cervical, ovarian, and aggressive prostate cancers.

Be as lean as possible without becoming underweight. . The increased risk of disease appears to be due to a higher prevalence of metabolic disorders in many obese people. Approximately 70% of obese persons have two or more metabolic abnormalities such as:

Hypertension

Elevated triglycerides, glucose and/or insulin

Low HDL cholesterol (“good cholesterol”)

High C-reactive protein (a key marker of inflammation)

It may be helpful to be able to calculate your own weight status by using the Body Mass Index (BMI)You simply divide your weight in pounds by your height in inches squared X 703.

For example: BMI =140 pounds divided by 64 inches squared (4096) X 703 = 24.0. A healthy BMI is 20 – 24. Being underweight is considered a BMI of less than 19.0.

Limit your consumption of red meat (including beef, pork and lamb).  There are several reasons:

The International Agency for Research on Cancer (IARC) classifies red meat as a “probably carcinogen”.  You don’t need to give up meat; however, an intake of up to 18 ounces a week can be safely consumed without too much concern. BTW, 4 oz. is about the size of a deck of cards.

Another factor that raises cancer risk is the overcooking of red meat that produces charred areas of the meat – goodbye grill marks?). These create carcinogenic hetero cyclic amines (HCAs) that have been linked to pancreatic and colon cancers.

Another carcinogenic compound comes from burning the fat from meat when grilling that produce polycyclic aromatic hydrocarbons (PAHs), linked to stomach cancer.

Hint: Both compounds can be lessened by using a marinade on the meat.

Highly processed meats such as bacon, hot dogs, and lunch meats are known for their nitrite and nitrate content used as preservatives.  Smoking meats can lead to the formation of N-nitroso compounds which are considered carcinogenic.

Avoid deep-fried foods. When cooked in this manner, foods are exposed to a chemical called acrylamide that increases the risk of prostate cancer.

There are other lifestyle factors that can influence epigenetically the risk of any chronic disease. Alcohol intake, for example is important due to the carcinogenic effects of alcohol itself. 

“Chronic inflammation, which is strongly associated with being overweight, can increase the risk of developing cancer.  Excess belly fat produces hormones that can raise levels of insulin, estrogen and leptin, all of which have been linked to cancer development.” (Finlayson, 2019). 

The interconnected factors that trigger chronic diseases are vast and subject to manipulation by the body as well as our microbial environment. It would be wise to attempt to take the best care of your body as you possibly can and begin at an early age.  Aging as you know itself becomes a central factor in the development of any chronic disease. In 1980, Dr. James Fries, Professor of Medicine, Stanford University introduced the compression of morbidity theory. This theory states that “most illness was chronic and occurred in later life and postulated that the lifetime burden of illness could be reduced if the onset of chronic illness could be postponed and if this postponement could be greater than increases in life expectancy.”). That theory tells it all. (Unknown source). SJF

Processed Food: Are We Addicted?

The following post may explain in part the possibility of food addiction, a highly controversial topic especially when it comes to processed foods.

Perhaps it is best explained by this excerpt from Michael Moss, Salt, Sugar, Fat: How the Food Giants Hooked Us.

” The blood gets especially besieged when processed food is ingested, flooding the system with its heavy loads of salt, sugar, and fat…, there, narcotics and food…act much alike. Once ingested, they race along the same pathways, using the same neurological circuity to reach the brain’s pleasure zones, those areas that reward us with enjoyable feelings for doing the right thing by our bodies. Or, as the case may be, for doing what the brain has been led to believe is the right thing.”

The following link provides us with a video (suggested (13 min.) and the text of a recent TED talk. Interesting analysis.
