Cooking  Disease  Nutrition  

Is healthy food still healthy AFTER you cook it? If you want to continue to improve your overall health and wellbeing OR you've been trying to improve a chronic health condition like diabetes, high blood pressure, or heart disease, then you MUST know how food preparation (cooking) can positively or negatively impact your health.

What is Cooking Really?

We all have fond connections to our kitchen experiences - at least I do! Two things I recall the most are my grandmother's homes. Gram B always had a skillet of bacon grease on the stove. When we'd show up, she would turn the stove on and fry some WONDERFUL eggs in that bacon grease. My other Grandmother, still living at age 99, would make thin pancakes (of course, fried in bacon grease!) and roll them with sour cream and jam filling.

It has been over 20 years since, but these memories are still rich... AND IMPACTFUL. To this day, even though I have expertise in human physiology and wellness, I default to cooking the way I was raised, and I definitely eat too much bacon!

Cooking is a Chemistry Experiment

Cooking is a chemistry experiment: sugars, proteins, and fats are combined in various amounts and heated under various conditions for a certain amount of time.

This is chemistry! And, in chemistry, the combining of sugar and protein under heat is called a Maillard Reaction, not cooking.

Time and temperature cause the breakdown of proteins and complex carbohydrate structures (like the softening of carrots). With time and temperature, a couple of things can happen to the food:

  1. The sugars bind to the proteins to create NEW molecules, which are called advanced glycation end products.
  2. The fats are damaged by the heat, called oxidation.

AGEing: How do advanced glycation end products contribute to diseases like diabetes?

Even though most people do not know it, science has firmly established the link between how meat is cooked and risks for diseases like diabetes.

Science has also established that THREE things most impact the health of our food when we cook them:

  1. Cooking TIME
  2. Cooking TEMPERATURE
  3. Moisture present

So, food changes the MOST (and generally becomes more stressful and less healthy to the human body) with LONG cooking times, DRY heat, and HIGH temperatures.

QUICK TIP: If you want to get started with healthier eating, just turn down the heat and try to cover your food to keep it moist during the cooking process.

I do have some bad news for you... those wonderful flavors your grandmother created when she fried the onions in bacon grease, when your dad chargrilled your burgers and steaks, and that crispy skin on your baked (healthy?) chicken and turkey... those wonderful flavors are actually created by the Maillard reaction!

I hate to say it, but there is some truth to the colloquial comment by many health experts, "If it tastes good, spit it out!"

Fortunately, taste is a subjective phenomenon, and anyone can develop a LOVE for fresh, healthy, raw or minimally cooked foods!

How can highly cooked food hurt our health?

Ok, now we know that cooking under high temperature, for prolonged time, and especially under dry heat conditions causes NEW chemicals to be created in food called Advanced Glycation End Products (AGE).

We know that these AGE can contribute to the modern diseases we see like diabetes, metabolic syndrome, and heart disease.

But, HOW do these AGE products cause disease?

The AGE chemicals are oxidants. AGE are chemically reactive substances. This means that these chemicals, created by cooking, can REACT with other molecules in the human body. When AGE react with other chemicals in the body, like proteins or cell surface receptors, the AGE can attach to these important parts of the cell and disrupt how the cell functions.

For illustration, think of a receptor on a cell. The cell is the smallest working part of the body. Every organ is made up of certain cell types. These cells work together to cause the organ to function. Each cell of the organ has "receptors" on its surface... these receptors are like antennae that allow the cell to communicate with other cells and with its environment.

If the receptor of a cell is BOUND by an AGE, then that receptor will either send an inaccurate signal into the cell OR block the reception of correct signals into the cell. Remember, the cell does its proper operation for the body ONLY when it can receive the correct signal.

The food we eat, and how that food is cooked, will create a healthy or stressful environment in the human body. We truly ARE what we eat.

Now I want you to imagine the average American diet. Day by day, month after month, and year after year a person can eat highly processed and highly cooked meats, eggs, and processed shelf-stable food.

Research tells us that "Ultra-Processed" foods account for 50% of the standard American diet and further account for 90% of added sugar intake.

Now imagine the impact of this highly stressful food can have on the human body after decades of eating... every day for decades.

Essentially, Americans struggling with chronic disease are just suffering from too much chemical stress on their bodies from eat processed foods, super-heated foods, and probably the chemicals from food processing.

How can food processing lead to immune system problems and food allergy?

Processing of foods and the subsequent Maillard Reaction (AGE formation) can create chemicals that disrupt cell communication (as discussed above). The immune system communicates through cell receptors. So, when the receptors on the immune system cells are blocked or disrupted the immune system can overreact or under react.

The immune reactivity can contribute to a heightened low grade chronic inflammatory state in the body. As we've discussed before, chronic inflammation is linked to complex chronic diseases like diabetes and heart disease.

When we eat foods that disrupt the communication of immune system cells, this can lead to immune disease and even food allergies.

What can we do now? Simple steps to begin to clean up our physiology and live a better life!

The benefits of reducing the intake of ultra-processed foods, super-heated meats and foods, and foods with long shelf life can be profound. (By the way, an ultra-processed food is any food that could get lost in your pantry for months and still look the same!)

Animal research has shown that the restriction of dietary AGE (superheated meats and ultra-processed foods) PREVENTS blood vessel and kidney disease, type 1 and type 2 diabetes, improves wound healing and insulin sensitivity (meaning, the receptors on the cell work better and so the cell functions better... leading to better physiology... and greater wellbeing!)

Step 1: Believe that HOW you cook your food WILL impact your health

Probably not today or tomorrow, but definitely over time.

Step 2: Teach your children and grandchildren

And start feeding them natural, minimally processed and gently cooked foods.

Step 3: Do a Food Journal

Writing down the foods that you are eating will allow you to OBJECTIVELY understand what you are really eating, how frequently, and the quality (or not) of the foods that you are eating.

Step 4: Believe that good food does NOT cost more in the long run

When you eat better food, you eat less. Why? Because processed foods are chemically designed to make you overeat. AND processed foods that cause inflammation disrupt your "I'm full now" receptors so you generally over-eat.

The human body does NOT need very much high-quality food. But I recognize that eating is something that we do for social and other psychological reasons (like boredom or to get a break from stress), so this is a tough thing to believe. But, in my experience it is still true!

Step 5: Learn more

Here's a research article that is very thorough. These researchers have tested a wide variety of foods to determine how stressful they are on the body (how high the food's AGE content is).

You can use this simple list to get a more detailed understanding of what foods you should start avoiding right away.

Take a look at these whole-foods recipes that taste great and are relatively easy to make.

I hope this article is valuable to you as you continue your journey to better health, health freedom, and authentic wellbeing.

Sincerely,

Dr. Jamie

Payments are securely processed through industry leader Authorize.net of which SupplementRelief.com is a Verified Merchant.

We DO NOT retain or store your credit card information after the purchase. We DO NOT share your information with anyone. We DO NOT auto-subscribe you to anything. Your information is YOURS.

The charge will appear on your credit card statement as SupplementRelief.com with our phone number (888) 424-0032.

Shipping & Handling

A safe and accurate address for delivery must be provided at the time the order is placed. Once an order has shipped, SupplementRelief.com is NOT responsible for lost or stolen packages CONFIRMED BY THE CARRIER to be delivered to the address provided for the order.

Since COVID-19, and the ensuing economic challenges in the USA economy, we respectfully ask that you allow some additional time for delivery for the carriers (USPS, UPS, and FedEx). Most orders still arrive on time, or near on time, but some may run late. We make every effort to get your order packed and into the carriers hands the same day, or by the next business morning if your order came in later in the previous day after carrier pickup, but we have no control over any delays that may happen within the shipping carrier's delivery system. Please order earlier for the time being if you are time-sensitive.

Orders that contain only FirstFitness Nutrition products have a shipping fee automatically calculated based upon the actual shipping weight of the items purchased. The charge ranges from $4.95 to $14.95.

For orders with NuMedica products you may choose from the shipping options below on the Order Checkout form in the Shipping Information section on the first line that says Choose Shipping Method.

Shipping Options

Country Option Schedule Cost
United States Standard 3-6 Days $4.95
United States Priority 2-4 Days $9.95
United States Free 7-10 Days $0.00
International FedEx International 4-7 Days $79.95*
International GlobalPost International 12-21 Days $39.95*
*International shipping costs may be higher depending upon package weight and destination. We will contact you for your approval of the additional amount if this occurs.

SupplementRelief.com may use the email or phone number provided on your Order to call or text you regarding Order Status or to inform you of changes to the Order Policy.

When your order ships we will send you a confirmation email with the delivery tracking information.

International Shipping

Shipping anything these days internationally is expensive. COVID resulted in more rigorous customs import processes, and now with much higher energy prices, international shipping rates are higher.

FedEx is the most reliable and faster carrier, at least for now, but they are expensive. Our FedEx international shipping fee is a minimum of $79.95. It usually makes more sense to get several months of supply (3 months or more) in one order to minimize the shipping expense per order over time. While the added weight of additional items may increase the base shipping price by a little (usually 10-25% depending upon total weight and destination), it is usually not by very much relative to shipping an additional small order later.

We also offer a lower-cost international shipping option using GlobalPost International for $39.95. So far, they have been reliable in getting packages correctly delivered but it takes 2 - 4 times as long to get the package delivered. Packages may take longer to process in the receiving country's customs process and status updates may not be reported as quickly. Please be patient if you choose this option to save money.

Some International orders may cost more to ship depending upon weight and location. If that happens we will contact you first and get your approval for any additional charge before proceeding. International orders may also be subject to additional customs fees and duties/taxes based upon the destination country's customs import laws and policies. These fees are NOT known or included on our order form and are typically charged and collected by the shipping carrier when they are delivering the product to it's final destination once the package has cleared the destination country's customs process. It is recommended that the buyer research custom import fees for the products/services they are importing beforehand to be aware of potential, additional fees.

Shipping Refrigerated Products

Our manufacturers formulate their probiotics to ensure their products retain viability until they reach the consumer. Probiotics that are recommended to be refrigerated remain so until the time of shipment, then shipped alongside an ice pack to ensure potency (Note: Ice pack will not arrive frozen, and product may not arrive cold). Orders placed on a Thursday-Sunday requiring cold shipping will not ship until the following Monday.

Cancellations

If your order has not been shipped yet, you can request a cancellation. Your original purchase amount will be refunded within three business days. If your order has already shipped, see Returns and Refunds.

Changes, Returns and Refunds

If you want to make a change to your order, please email us as soon as possible so we can make the change before your order ships. If your order has already shipped you may incur additional shipping charges for the second shipment and the return label for any products returned.

If we have made a mistake on your order, or the product arrives in a damaged or unusable condition, we will make every reasonable effort to right the situation quickly to your satisfaction. Problems of this nature must be reported to us within 5 business days of the package delivery date documented by the carrier status.

We accept returns subject to when the return is requested and the condition the product is returned in. All returns must first be authorized by contacting us. In your request, please let us know why you are returning the item(s). We will respond promptly with authorization, the return address, and a return shipping label if appropriate.

If your order has already shipped you can return any un-opened products within 30 days of receiving your order for a 100% refund of the price paid for the product, less the actual shipping charges we incurred to get the product to you originally and then returned, less a $10 restocking fee. Un-opened means the protective seal on the bottle or container, or the shrink-wrap on the box or kit, has not been broken and the product has not otherwise been damaged in any way. You may use the original packaging for the return or acquire your own. We will provide the return shipping label. We DO NOT accept returns for NuMedica products once the protective product seal has been broken.
