One size does not fit all when it comes to nutrition.

A food that might be helpful to one person could have some unwanted effects for another, said Dr. Kathy Stricker, board certified doctor of natural medicine and author of the book “Redesign Your Life.”

But how do you know if that rutabaga is right for you?

A test called Nutrition Response Testing, or NRT, is available to find out which foods should be on your plate. The noninvasive procedure is becoming popular nationwide, as more clients confirm that the knowledge gained by the testing has aided or even restored their health.

Stricker is a firm believer in NRT, one of the options she offers her clients that can be done in her office.

Based on muscle testing and kinesiology, the science of movement, NRT compiles an analysis of the body to help to determine the exact nutrients needed to supplement each individual’s diet.

“Let your food be your medicine,” Stricker said. “People don’t listen to their bodies enough, but we design a program that your body will like nutritionally.”

Variety of tests

Stricker is the owner of Day Star Natural LLC in Mount Penn, where she helps clients attain their optimal health, beginning with a variety of tests to find answers to their health problems.

Joyce Brice of Wyomissing consulted Stricker after all other treatments she tried for a rash had failed.

“I had some health issues, and I tried to educate myself on what to do,” Brice said. “You can get a lot of information online, but not all of it is helpful.”

Brice had a rash on her legs for more than a year, and even though Brice was working in the medical field at the time, nothing anyone suggested worked.

After analyzing Brice’s diet, Stricker told the young woman she was eating too many mushrooms and that part of her diet was contributing to an overgrowth of fungus.

“The education she gave me was helpful and it put me on the right track,” Brice said. “It’s not ‘everybody should do this;’ instead, it’s individualized.

“She helped me tremendously, the rash is gone, and now I am a true believer,” Brice said.

At Day Star Natural, Stricker helps people by utilizing the science of whole body health and wellness, she said.

“If there’s something your body is missing nutritionally, we’re able to help you,” Stricker said. “We look for a response that works better for you, and we design something that works individually because each person has differing nutritional needs.”

People often don’t realize they might have food sensitivities, Stricker said, and that might be the problem.

Clients may be required to make changes in their diet and eating habits for an optimal response.

“We try to make healthy suggestions,” Stricker said.

The doctor speaks from experience. Earlier in her life, she was experiencing serious health problems and sought help.

Changing her diet was one of the suggested treatments.

“At first, I didn’t think diet had anything to do with it,” Stricker said.

But she was desperate. So, for a year, Stricker eliminated all sugar, dairy products and fruit from her diet.

“I was so much better,” Stricker said. “And I don’t count calories. I listen to my body.”

Holistic approaches

With tests like the Nutrition Response and VoiceBio Analysis, Stricker uses holistic approaches to help individuals age in a healthy way.

The VoiceBio Analysis is a tool to check the (radio) frequency of the body to see how well organs and areas of the body are working.

“As we age, our bodies don’t require those building blocks of protein that they did as we were growing,” Stricker said. “Anyone over the age of 50 should evaluate their diet, because they might need to make some changes.

“A lot of people discover this too late and come to me in their 70s or 80s, but when they’ve taken my suggestions, they’ve done well,” Stricker said.

A good quality of life is naturally what everyone wants, she said.

Depending on how you’re taking care of yourself, including your nutrition, you might have to make some changes to get it.

“Quality of life at the end is the same as when you’re younger,” Stricker said.

Stricker graduated from high school in 1967 and occasionally she sees people who are the same age, but who look much older and are in much worse shape than they would have to be.

They have aged prematurely and could be healthier now if they would have taken better care of their health earlier, she said.

“Looking around, I’ve seen some in terrible health, and I don’t want that for them and I don’t want that for me,” Stricker said. “I want to be able to do things, to go where I want to go, and not have to carry equipment with me.”

Her tips to folks include stay away from sugar, processed and fast food, and eat in moderation.

If you feel “stuffed” after a meal, you should have stopped eating ten minutes ago.

Her book, “Redesign Your Life” is a guidebook relating to health and diet.

Find issues

Dr. Zachary Fatkin, a chiropractor whose office is on East Bellevue Avenue in Muhlenberg Township, also does Nutrition Response Testing for his clients. Fatkin says the test can find late-developing nutritional issues.

“You can find out what’s stressing the body,” Fatkin said. “The test can discover if you’re having a difficult immune challenge, if you have heavy metal toxins, inflammation or food intolerance. We can identify if there’s a weakness in the body’s immune system.”

Fatkin is on a mission for nutrition because of his own past experience.

“I am a recovering sugar addict,” Fatkin said. “I had health problems in my mid-30s, until my health crashed. I didn’t want to take medications, so I tried improving my nutrition.”

The nutrition regimen worked and Fatkin regained his health.

“So that’s why I’m passionate about what I do,” Fatkin said.

The doctor does presentations to schools and civic groups about nutrition, because many people’s poor food choices are quite literally making them sick.

In his public health talks, Fatkin tells his audience that about 80 percent of products in a grocery store are processed foods.

“It tastes great, but unfortunately, they’re very bad for our bodies,” Fatkin said.

Everybody wants to slow the aging process, and thoughtful eating can help.

“You can age slower or faster, depending on what you’re putting in your body,’ Fatkin said. “Eat whole foods, or foods that are what they are: Chicken is chicken, an apple is an apple and broccoli is broccoli.”

The Nutrition Response Test is great because it takes the guesswork out of finding good nutrition, he said, by helping to discover each person’s nutritional deficiencies.

“The western diet is filled with processed food and plenty of sugar,” Fatkin said. “Diet is a whole big part of whether people stay healthy or get sick, and a good diet can slow the aging process.”

People mostly live in a toxic environment today, Fatkin said, surrounded by chemicals and fossil fuel fumes.

“As we age, because we do live in this kind of environment, our bodies need extra immune help and we need extra nutritional support,” Fatkin said. “Our immune systems are taxed. They’re working hard.”

Along with eschewing processed foods, Fatkin has one important tip: Get off the sugar. By making small changes, he said, it can be done.
