Why is Nutrition important for healing?

We fundamentally break down nutrition into macronutrient and micronutrient needs. That is protein, fat, & carbohydrate ratio relative to vitamin and mineral density in the diet, respectively. 

When it comes to healing, the body in particular needs an adequate amount of amino acids from protein in order to re-build the tissues that were damaged. This process also requires a variety of micronutrients that fuel the energy consuming pathways that make this possible. 

During the healing process, it is equally as important to avoid the harmful foods as it is to incorporate the good ones. For example, we frequently recommend elimination of processed carbohydrates, refined sugars, and processed vegetable/seeds oils because these are all inherently inflammatory and will delay the healing process. 

At Cross-Up, we can help you better understand what your current diet is providing and how to fill in the gaps with appropriate nutrition. 

Chiropractors have vastly more training in nutrition than other medical programs; meanwhile, Dr. Peyton and Dr. Jack have extensive training outside of that program as well. 

Nutrition is not about dogma or the latest fads. It’s a concrete understanding of the fuel you are giving your body to maintain homeostasis or harmony of your physiology. 

Diet & Nutrition's role in Chronic Disease


We live in a time of abundance – a blessing in many cases. It’s a shame that the most readily available and affordable foods are often the most heavily processed and riddled with chemicals and calories the overwhelm the body.

Drop the gimmicks and support your body by giving it proper and uncontaminated fuel. Find out the best macronutrient balance for you that also provides complete micronutrient support. 

When this is achieved, you will allow your body to most efficiently detoxify harmful chemical, strengthen the gut & brain barriers, balance and effectively respond to hormones, and mount an appropriate immune response. 

Sometimes these processes require a kick start, so fortunately we have access to affordable and effective professional-grade diet & nutrition supplements from a trusted source!

Effective treatment of any condition comes down to consistency. This is why developing a plan for the long term and using diet & nutrition in the right way is so important. Getting better is easy, but we want you to have the tools and knowledge to stay better.

Nutritionist Dr. Jack P Rieke

Chiropractor, Active Release + Rehab Specialist

Dr. Rieke is always looking to build on the tools and resources he can use to provide the best care for every patient. He was inspired by Chiropractic at a young age when his mother suffered from severe and chronic pain. After seeing about 13 specialists and undergoing countless failed procedures, his mother finally experienced effective and lasting relief by visiting a Chiropractor. After becoming a patient himself, he recognized the immense impact this practice makes on the lives of many and knew right away that he wanted to pursue this career of service to others.

Nutritionist Dr. Peyton Habenicht

Chiropractor, Acupuncturist, NET, FMT, Webster Certified

At just 14 years old, Dr. Habenicht developed a passion for Chiropractic Medicine and decided this field was her future. As a committed soccer player, Dr. Habenicht was always searching for real health solutions instead of medication for her injuries. In high school, she sought out Chiropractic Care for a severe ankle sprain. As a result she experienced full resolution of ankle pain and weakness, and due to the comprehensive nature of the practice she also had relief of hip pain and a reduction of GERD symptoms and debilitating migraines.

General Approaches to Nutrition

We use several approaches at Cross-up Chiro, depending on our patient’s needs. The key is that you as the individual are the most important factor and together we will find what works best in your case.

Weight Loss

For these plans, we do a comprehensive food journal and calculate your nutrient needs based on current size and age and then establish a plan relative to your desire. We do not believe that starvation is a valid approach and we plan for long term improvement.

Functional Medicine

This form of medicine uses blood work to coroborate necessary changes in the nutritional intake. At Cross-Up, we are trained in blood work analysis and can help you better understand your decifiencies based on your physiology. 

Autoimmune Disease & Chronic Disease

A primary trigger of chronic autoimmune activity in the body is certain foods we eat. It is essential to eliminate the triggers and replace them with nutrient dense foods that will support your body rather than break it down. We develop a specific plan for you and your condition. 

Vertical Diet for Athletes

This Diet was coined by Stan Efferding who has trained athletes in all disciplines. A horizontal diet is eating massive varieties. The vertical diet establishes a regimen of foods that completes the nutritional picture and is easily digestible, while keeping the food choices consistent. 

“Our focus is on finding and fixing the underlying problem – not just masking it.”

What does a nutritionist do?

A nutritionist conducts a thorough assessment of your health condition, current diet and lifestyle, emotional relationship with food, daily routine, and your goals. We also calculate your Total Daily Energy Expenditure to understand caloric needs. With all this information in mind, we establish an economically feasible plan that specifically fits you and your health needs.   

What is a nutrition plan?

This a detailed regimen of foods and a meal plan appropriate for your health needs and weight management goals. This includes a macronutrient breakdown between carbohydrates, proteins, and fats with a complete profile of micronutrients to meet your physiological requirements. 

What does nutrition help with?

Everything. Nutrition is the fuel for every process in the body. There are so many nutrients required for energy metabolism, organ function, cell turnover, immunity, and growth that we must be cognizant of acquiring every single day. 

When to see a nutritionist?

We all at some point, should receive a detailed assessment of our current lifestyle and nutrient profile. So many conditions are exacerbated by diet induced chronic low grade inflammation, and we can intercede with positive dietary change long before any symptoms occur.
