Join Kristine Jelstrup of Central Square Health and Wellness from 7 to 9 p.m., November 16, at Citywide Senior Center, in Cambridge, for a free workshop to learn which foods are the most toxic, how to do Muscle Response Testing and how to read and grow one’s energy field to figure out which foods are best for us and our families.

Commercially grown crops are an epic health failure. Environmental factors such as GMO crops and the toxins that are sprayed on them are adversely affecting our health and negatively altering our genes and the genes of future generations. Every human has an energy field that can be used to access health information about the body. The Morphogenic Field grows when the body is fed nutritious food and it shrinks when the body is fed toxic food. It is possible to figure out how food is affecting our health through Muscle Response Testing.

Jelstrup, CMFT, CBK, LMT, has been a natural healthcare practitioner in Cambridge for more than 18 years, using various forms of applied kinesiology to find the root cause of health problems whether physical, chemical or emotional. Once identified, the blockages are released and organ systems are supported with nutrition to restore the body to good health. The three techniques she uses the most are Morphogenic Field Technique, Koren Specific Technique and Bio-Kinetics Health Systems.
