Several studies alert us to the weakness of fruit and vegetables "modern" nutrients. WHILE A PEACH WAS ENOUGH IN 1950 TO ABSORB A GOOD RATIO OF VITAMIN A, TODAY WE NEED TO EAT 20! Where are these vitamins? What the researchers say ? Does the food industry benefit? Basta conducted the survey. "Eat at least 5 fruits and vegetables a day," recommends the National Health Nutrition Program. Perhaps we will soon need to eat 50 ... From the nutrients side, our food seem to show some weaknesses. Take an orange: The 2000’s one will probably look better than oranges of the 1950’s. However... THE MODERN ORANGE CONTAINS 5 TIMES LESS IRON.... The same for peaches. Several studies show that loss of "nutrient density". The problem of nutrient density loss for fruits and vegetables began to be raised in the US, Canada and Great Britain. Vitamin A: 1 Peache in 1950 = 26 peaches in 2010 Since 1950, researchers measure the nutritional content of food. So in the 1950’s, eating a banana, an orange and a peach, was enough to fill the "recommended daily allowance" (RDA) of vitamin for a person. TODAY, GIVEN NUTRIENT CONTENT, IT SHOULD BE 5 BANANAS, 10 ORANGES AND 26 PEACHES TO HAVE THE DOSE OF VITAMIN A! The rheumatoid arthritis patients with fibromyalgia syndrome had significantly lower levels of vitamin D than those without. REFERENCE:
Abstract AIM: To assess vitamin D levels in rheumatoid arthritis (RA) patients and to find their relation to clinical parameters, fibromyalgia syndrome (FMS), quality of life (QoL) and disease activity. METHODS: The study included 63 RA patients and 62 controls. Clinical examination and laboratory investigations were performed. For patients, the Disease Activity Score (DAS-28), QoL index, Health Assessment Questionnaire II (HAQ II) and Modified Larsen score were calculated. 25-OH-vitamin D was measured in patients and controls. RESULTS: The patients' mean age was 41.59 ± 9.69 years and disease duration 5.89 ± 3.67 years. The level of vitamin D in RA patients was significantly lower (23.11 ± 12.71 ng/mL) than that in the controls (32.59 ± 13.06 ng/mL) (P = 0.005) being deficient in 50.8%, insufficient in 23.8% and normal in 25.4%. The RA patients with FMS (n = 33) had significantly lower levels of vitamin D (19.08 ± 10.59 ng/mL) than those without (27.55 ± 13.51 ng/mL) (P = 0.008). The difference was significant on comparing those receiving hydroxychloroquine (17.39 ± 7.84 ng/mL) to those not (31.85 ± 13.85 ng/mL) (P < 0.001). Vitamin D significantly correlated with QoL index (r = 0.58, P < 0.001) and negatively with HAQ II (r = -0.36, P = 0.004) and BMI (r = -0.39, P = 0.001). CONCLUSION: Special attention is required regarding vitamin D levels in RA patients with FMS and decreased QoL. Vitamin D should be corrected and supplementation considered among the RA management armamentarium. http://www.ncbi.nlm.nih.gov/pubmed/25291242 Int J Rheum Dis. 2016 Mar;19(3):294-9. doi: 10.1111/1756-185X.12426.

There is evidence from several well documented case reports that occasional patients with rheumatoid arthritis (RA) may develop aggravation of their arthritis as a result of allergy to some ingredient in the diet. A variety of foodstuffs have been implicated including milk and milk products, corn and cereals. Total fasting results in improvement in rheumatoid arthritis, but appears to be mediated by diminution in production of chemical mediators of inflammation, rather than by elimination of a dietary allergen. There is conflicting evidence from studies using various intestinal probes that patients with rheumatoid arthritis may have a 'leaky' intestinal mucosa allowing food allergens to be more easily absorbed. Clinical therapeutic trials of exclusion diets have employed the standard strategy of the double-blind randomized method. However, this presupposes that patients entered into such a study are capable of improvement with dietary manipulation.
Since this is often not the case, a more appropriate method would be to employ the 'intensive research design' also known as 'single case experiment' and 'N of 1' study. 'Masked food intolerance' is an attractive hypothesis, but extremely difficult to prove. It is doubtful whether fish oils and/or evening primrose oil will be of significant long term benefit for patients with RA. However, they do provide for the possibility that a fatty acid-like substance may be found which may be incorporated into cell membranes, thereby preventing production of mediators of inflammation, such as prostaglandin E2 and leukotriene B4. http://www.ncbi.nlm.nih.gov/pubmed/2012942 Br J Rheumatol. 1991 Apr;30(2):125-34. Is diet important in rheumatoid arthritis? Buchanan HM1, Preston SJ, Brooks PM, Buchanan WW. Patients with periodontitis had significantly lower intake rates of vitamin C, folic acid, magnesium, and fiber than those of healthy controls. AbstractOBJECTIVE: Recent studies have shown that inflammatory diseases can be influenced by nutritional factors. For this reason, this study was designed to evaluate the food intake of patients with periodontal disease in comparison to healthy subjects using a 7-day food record (7-DFR). METHOD AND MATERIALS: The study population consisted of 42 patients with chronic periodontitis and 38 healthy subjects (controls). Periodontitis was diagnosed by using the Plaque Index, Sulcus Bleeding Index, and measurement of probing depth. All participants completed a 7-DFR, which was analyzed with DGE-PC Professional 2.7. To confirm the nutritional analysis, the vitamin C plasma level of each participant was measured. Additionally, the oral discomfort of patients with periodontal disease was ascertained by using an additional questionnaire. RESULTS: Analysis of the 7-DFR revealed that patients with periodontitis had significantly lower intake rates of vitamin C, folic acid, magnesium, and fiber than those of healthy controls. The mean vitamin C plasma levels were significantly lower in patients with periodontitis (0.63 mg/dL) compared with healthy control subjects (1.13 mg/dL, P < .05). Evaluation of the questionnaire showed that approximately 50% of patients experienced discomfort while eating. CONCLUSION: The present study shows that patients with periodontitis have a reduced intake of vitamin C, folic acid, magnesium, and fiber compared with healthy subjects. This is possibly an outcome of oral discomfort during mastication. To avoid an insufficient nutrient supply for a patient with periodontal disease, the patient's choice of foods should be closely monitored. REFERENCE:

It was demonstrated that serum vitamin D levels of Hashimoto's thyroiditis patients were significantly lower than controls, and vitamin D deficiency severity correlated with duration of Hashimoto's thyroiditis, thyroid volume, and antibody levels. These findings may suggest a potential role of vitamin D level in development of Hashimoto's thyroiditis and/or its progression to hypothyroidism. REFERENCE:
