The Most Common Ways that Food Nutrients are Destroyed

One of the greatest concerns with the food supply today is the toxicity and lack of nutrients. This begins with the seed, then the soil it is planted in, followed by the treatment it receives during its growth phase. But if that wasn’t enough, a further degradation of food takes place between the harvest and the plate.

These are the three most prominent ways in which nutrients get destroyed in your food.

Processing
The most processed food category is arguably the grains. In order to produce flour, they often undergo a process that leaves them with a fraction of the nutritional value compared to when they were initially harvested.

To begin with, the highly nutritious, sprout-able bran and the fiber-rich husk are removed. Only the light-yellow endosperm remains, which is virtually all starch, with a high glycemic index rating and very little nutritional value.

Following that, in order to bypass the aging process, add shelf life, and get a clean white color, the endosperm is crushed and treated with chlorides to make it instantly white. A byproduct of that process is alloxan, which is used to induce diabetes in lab animals for medical testing.

What is left is a food that has a mere remnant of its original nutrient value.

Heating
Another way the nutrients in food are destroyed is through heating. Many phytonutrients, enzymes, probiotics, and vitamins do not survive the heating process.

One such process is pasteurization. This is commonly done with dairy products in order to remove any rogue bacteria that may be present during the harvesting. Unfortunately, this process also removes delicate and beneficial nutrients like enzymes and good bacteria, which are crucial for proper digestion and health.

Another common practice is to cook foods in the oven or on a stovetop at high temperatures for extended periods of time. This also results in the destruction of various nutrients.

Finally, microwaving is the worst way to cook food. This method excites the water molecules inside whatever you are cooking, causing heat formation from the inside out. The result is a near-total molecular decomposition of the nutritional content.

This leaves microwaved food almost completely dead, leaving nothing but empty calories, fiber, and minerals. Virtually every vitamin and phytonutrient has been destroyed.

Irradiation
This process exposes food to radioactive materials, such as cesium-137 and cobalt-60, in order to kill insects, bacteria, mold, and fungus, as well as prevent sprouting and extend shelf life. Unfortunately, foods that have been irradiated lose much of their nutritional value.

Irradiation can destroy between 5 and 80 percent of the vitamins and nutrients found in various foods, including essential vitamins A, B complex, C, E, and K. For example, irradiated eggs lose 80 percent of vitamin A, and orange juice loses 48 percent of beta-carotene.

Although the heating and irradiation processes are often mandated by governmental organizations to reduce the number of food-borne illnesses, this may bring about other health problems, since probiotics, enzymes, and other nutrients that help the body resist infection get destroyed.

Consuming more whole, fresh foods will strengthen the health of your immune and detoxification systems to better fight off harmful pathogens.

Healthy Plant-Based EatingTips

Plant-based eating is nothing new, but it seems to be more of a trend as we seek ways to improve our health.

Sharon Palmer, RDN, The Plant-Powered Dietitian™, said eating a diet focused on plants can reduce the risk for heart disease, cancer, and type 2 diabetes.

“And there’s another added bonus,” she notes. “Plant-based eaters tend to be slimmer.”

1. “Start your meal with a vegetable-rich soup or salad,” Palmer says. According to a 2007 study published in Appetite, eating vegetable soup 15 minutes before a meal resulted in 20 percent fewer calories being consumed at the meal. Similar results were found when people ate a small salad prior to the meal.

2. Fill your plate with vegetables. “Filling at least half of your plate with veggies during mealtime can help make you feel more satisfied, with fewer calories consumed,” Palmer says.

3. Enjoy a fiber-rich whole grain or legume entrée. Research shows that a diet high in refined carbohydrates (such as refined breads, snacks, and baked goods) may increase the risk of diseases such as type 2 diabetes. “Eating more whole grains and legumes may help lower this risk, as well as lead to weight loss,” Palmer says. “These foods are not only high in fiber, but they displace extra calories found in more energy-dense foods, such as fatty meats.”

4. Get fruity for dessert. You can satisfy your sweet tooth with fruit and consume more phytochemicals, vitamins, minerals, and fiber at the same time. “[It’s] just what the doctor ordered!” Palmer says.

The Truth About Fats

When you want to lose weight or get healthy, what is the first thing you would normally cut from your diet? If you said fat, you’re not alone.

For years, the advice from the USDA has been to reduce the level of saturated fat in your diet, in order to lower your overall cholesterol. However, a new meta-analysis published in the Annals of Internal Medicine has thrown that whole approach in to question.

The removal of fats from our diet has led to an increase in consumption of carbohydrates and processed low-fat alternatives, which has contributed to record levels of diabetes and obesity.

When you consider that most low-fat or non-fat products are laden with salts, sugars and preservatives, continuing to seek out fat-free alternatives could be doing you more harm than good.
