Inflammation is a normal, much needed part of the body’s healing process in response to cellular injury. However, chronic inflammation can cause or advance many chronic diseases, such as cardiovascular disease, metabolic syndrome, cancer, autoimmune diseases, and neurological diseases. Your diet directly influences inflammation in the body.
Previous posts by GrassrootsHealth have specifically covered vitamin D in relation to inflammation and mental health, and omega-3s in relation to inflammation and heart health, as well as the association between inflammation and Vitamin D among the 24 different diseases. Today’s post will focus on general dietary characteristics that have been shown to decrease inflammation and lower levels of inflammatory markers, specifically high-sensitivity C-reactive protein (hsCRP), a marker included in our Inflammation Panel. Yesterday’s post featured an update on hsCRP levels among GrassrootsHealth participants; almost three fourths (74%) of participants had CRP levels <1.0 mg/L (low risk), 19% had levels between 1.0 and 3.0 mg/L (average risk), and 8% had levels between 3.1 and 10.0 mg/L (increased risk). Lower levels of inflammation have been associated with higher levels of vitamin D and plant-based diets.
How Can Diet Affect Inflammation?
Several different nutrients and compounds, such as polyphenols, omega-3 fatty acids, and antioxidant vitamins, have been shown to have anti-inflammatory effects, while others, such as some saturated fats, trans-fatty acids, and sugars, have pro-inflammatory effects. For example, antioxidants from fruits and vegetables inhibit inflammation-causing free radicals, and both antioxidants and omega-3 fatty acids inhibit the production of cytokines, which also contribute to inflammation.
What Does an Anti-Inflammatory Diet Look Like?
An anti-inflammatory diet may include foods that
- are low in refined carbohydrates (such as sugar, white bread, white rice, etc.)
- are high in soluble fiber (such as whole grains, fruits, vegetables, legumes, etc.)
- are high in mono-unsaturated fatty acids (such as nuts, avocado, olive oil, etc.)
- have a higher omega-3 to omega-6 ratio (such as fatty fish, flax seeds, spinach, etc.)
- are high in polyphenols (such as dark berries, cherries, grapes, dark chocolate, etc.)
Mediterranean Diet Shown to Reduce hsCRP
Research has established a consistent correlation between diet and inflammation, such as that done by Casas et al. on the Mediterranean diet (MedDiet). This particular study demonstrated the effects of diet on inflammation among 165 participants who had a high risk of cardiovascular disease. The participants were randomly split into three groups and had to follow a specific diet for 5 years: one group was put on a MedDiet supplemented with olive oil, another on a MedDiet with nuts (walnuts, almonds, and hazelnuts), and one on a low fat diet.
The MedDiet diet generally consists of:
- high intake of fruits, vegetables, whole grains, nuts and legumes, with olive oil as the main source of fat
- moderate intake of fish, poultry and alcohol (particularly red wine, with meals)
- low intake of red and processed meats
What were the results of the study?
As you can see in the chart below, both groups on the MedDiet experienced decreased inflammation (as measured by hsCRP), while the low fat diet group did not.
In conclusion, this study demonstrated long-term, anti-inflammatory effect of the MedDiet, specifically among participants at high risk of cardiovascular disease. The opposite was found for those on the low fat diet.
What can you do with this information?
Do you know your levels of inflammation? Get a glimpse of the amount of inflammation in your body with the Inflammation Panel, offered by GrassrootsHealth. Measuring hsCRP and HbA1c along with vitamin D and omega-3s can provide a clue about how much inflammation exists in the body and whether additional changes should be made to decrease inflammation, with supplementation, dietary changes, or both.
Are You Getting Enough Vitamin D to Help Yourself?
We’re in a time of great crisis that could be greatly affected by making sure you and everyone you know has a serum level of at least 40 ng/ml. Help us help you.
Do you know what your vitamin D level is? Be sure to test today to find out, and take steps to keep it within a target of 40-60 ng/ml or 100-150 nmol/L! Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases.
GrassrootsHealth Nutrient Research Institute is preparing to do a Community RCT with the use of our myData-myAnswers nutrient health system that over 15,000 people are already using for their health. We will demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to establish the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction with different ethnicities in the population. Please let us know if you’re interested in helping sponsor this project.
Through GrassrootsHealth Nutrient Research Institute, you can also test your essential elements magnesium, copper, zinc and selenium, toxins such as lead, mercury and cadmium, as well as your omega-3 levels, inflammation levels and thyroid stimulating hormone (TSH) level. Find out your levels today! Log on to the test selection page (click the link below) to get your tests and see for yourself if your levels can be improved.
Make sure you track your results before and after, about every 6 months!
How can I track my nutrient intake and levels over time?
To help you track your supplement use and nutrient levels, GrassrootsHealth has created the Personal Health Nutrient Decision System called
For each specific supplement, you can track what days you take it, how much, and many other details. This will help you know your true supplemental intake and what patterns of use work for you to reach and maintain optimum nutrient levels. Check it out today!
