5. Artificial food additives
Food additives can only be found in packaged foods; these consist of monosodium glutamate (MSG) and aspartame. These have been reported to trigger inflammation, even more so in people that already suffer from arthritis. MSG has been associated with palpitations of the heart, muscle weakness, and numbness. To further prove the ill effects MSG can cause, a study found constant consumption of products that contain MSG can lead to obesity, inflammation in the liver and heart disease.
