UNPROCESSED FOOD?

“Unprocessed or minimally processed foods are whole foods in which the vitamins and nutrients are still intact. The food is in its natural (or nearly natural) state. These foods may be minimally altered by removal of inedible parts, drying, crushing, roasting, boiling, freezing, or pasteurization, to make them suitable to store and safe to consume. Unprocessed or minimally processed foods would include carrots, apples, raw chicken, melon, and raw, unsalted nuts.”

We talk a lot about the bad stuff (processed foods) and not about the good stuff – unprocessed food. Good definition above. These are beginning to be hard to find in the supermarkets. The following article reports on a doctor’s experience of what it is like to eat Ultraprocessed foods for one month.

What Healthy Eating Means Now

After years of research on the subject, the consensus appears to be that there is no single diet that’s right for all of us. However, we have learned that we have a better idea of what healthy eating looks like.

The key is your overall eating pattern, not so much how many grams of carbohydrate, fat or protein you eat, or whether it is animal or plant protein. The choices are many: vegetarian?, vegan?, low fat?, low carb? Or perhaps flexetarian ( a little of both?)

The general healthiest pattern is emerging that consists mostly of nutrient dense whole foods that come from nature and includes few, if any highly processed foods. A closer look at this pattern recommends lots of vegetables and avoid sugar and refined grains.

When assessed for weight control, studies show that when individuals are divided into two major groups either low fat or low carbohydrate ,both groups lost weight – an average of 12 pounds, though some lost as much as 50 pounds. The participants also ate healthier and greatly improved their risk factors for heart disease and diabetes: body fat, waist size, blood sugar, blood pressure, cholesterol and insulin levels all of which can contribute to heart disease and diabetes.

A most important recent finding is that eating healthy can make a difference in how well your immune system functions, so important now as it is greatly needed to fight COVID-19. 70 percent of our immune system resides in the gut; therefore we must become more aware of providing nutrients that feed these gut bacteria. Packaged foods create inflammation and hamper immunity. These include not only sweetened drinks, but breakfast cereals, refined bread and pasta. Look more toward whole grains. “A poor-quality diet loaded with sugar, saturated fat, salt, and chemicals is second to only to smoking in terms of its negative effects on health and lifespan,” says, Dr. Steven Heymsfield, professor at the Pennington Biomedical Research Center at Louisiana State University in Baton Rouge, who was part of the development of the 2020 USDA Dietary Guidelines.

The best diet is the one that you choose after looking at the evidence that provides healthy benefits. Dr. Heymsfield says: “You could even try a diet for several weeks while keeping track of how it affects your weight, level of hunger and fullness, your mood, blood pressure and level of energy. Then try another for a few weeks and compare the results.”

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

Obesity and Covid

“Obesity is an extremely complex, multifactorial disease, with many of its most harmful effects arising from hormonal stimulation. Adipose tissue is an endocrine organ, and more than a hundred different hormones are produced by fat cells. As the cells expand with weight gain, production increases. Some of these hormones cause inflammation or trigger blood-clotting mechanisms, while others raise blood pressure or lead to insulin resistance, for example. Obesity affects virtually every body system and is associated with more than 200 medical conditions.”

The Japanese Diet: Deconstructed

The Japanese diet is one of the world’s lowest in fat. Other attributes include fish as a mainstay and soy foods. The Japanese also care about appearance and think of food as an art – resulting in more appetizing and satisfying foods. Do these characteristics contribute to the Japanese record of low rates of major chronic diseases and the fact that they boast the world’s highest life expectancy – age 76 for men and 82 for women?

In contrast, in 1980, 30 percent of U .S. adult population were affected by at least one chronic condition. Today it’s 60 percent. The percentage of those affected by two or more chronic diseases has grown from 16 percent to 42 percent. What and how do the Japanese eat? Often, it is Interesting to study lifestyles, in particular what and how other cultures eat to gain some insights as to what exactly is a healthy diet. No one expects the typical American to start munching on seaweed but the study indicates that what and how we eat can affect our overall health and longevity.

Got Milk?

“Indeed, the already booming nut-milk industry is projected to see continuous growth. Much of this is driven by beliefs about health, with ads claiming “dairy free” as a virtue that resonates for nebulous reasons—many stemming from an earlier scare over saturated fat—among consumers lactose intolerant and tolerant alike.”

Does Diet Affect our Risk of Chronic Disease?

Chronic inflammation and oxidative stress are conditions that are strongly related to the development of heart disease, diabetes, osteoporosis, Alzheimer’s disease, cancer and other diseases leading to disabilities and death in the U.S. today. The following are types of foods that increase inflammation: oxidative stress, or both.

Decreased: Colorful fruits and vegetables, dried beans, whole grain, fish and seafood, red wines, dark chocolate, olive oil, nuts, coffee.

Increased: Processed and high-fat meats, high-fat dairy products, baked products, snack foods with trans fats, soft drinks, other high-sugar beverages.

Dash For the Dash?

“The prevalence and severity of today’s hypertension crisis cannot be overstated. Too many people over ages 65 and 75 have dangerously elevated systolic blood pressure. On the basis of the available evidence, we can roughly estimate years of life lost attributable to hypertension. From the data we were able to collect and analyze, we estimate that approximately 37,712,740 years of life may have been lost between 1980 and 2014 due to hypertension as an underlying cause in adults aged 45 to 85+ years.”

Blood pressure has typically been measured by a doctor visit and if needed, the patient is given at least one (or two) prescriptions for lowering your blood pressure if necessary)(like a diuretic, e.g.) These drugs have served us fairly well in blood pressure control; however, one therapy is hardly mentioned as part of prevention or treatment along with the proper drug therapy, that if followed could enhance this goal.

That would be a diet that has been tested by research and shows up in the popular media as the second most popular diet known as the DASH Diet (Dietary Approach to STOP Hypertension not only for weight control but for blood pressure control also. In the list below, hypertensive disease ranked third as the top underlying medical conditions linked with COVID-19 deaths often associated with a more severe infection.

The following are the top underlying medical conditions linked with COVID-19 deaths.

* Influenza and pneumonia

* Respiratory failure

* Hypertensive disease

*  Diabetes

* Vascular and unspecified dementia

* Cardiac Arrest

* Heart failure

* Renal failure

* Intentional and unintentional injury, poisoning and other adverse events

* Other medical conditions
