Antioxidant status and smoking habits relationship with diet

One of the pathogenic mechanisms that can explain this increased risk in diabetes is the imbalance between pro-oxidants and antioxidants, which results in oxidative stress OS Sies, Under this perspective fish oils and omega-3 are under research and several papers have been published demonstrating their efficacy in protecting cardiovascular system and thus reducing the risk of many cardiovascular diseases [ 31 ].

The cooperation of all antioxidant components can provide more protection against ROS than any single compound alone. The antioxidant system includes various endogenous molecules 17 such as reduced glutathione GSHuric acid, billirubin, ceruloplasmin, ferritin, vitamins such as ascorbic acid, and tocopherol 18 and a lot of enzymes such as superoxide dismutase, catalase, glutathioneperoxidase 19 - Second, we recruited control subjects from the general population via press advertisements.

It is suggested that dietary antioxidants are insufficient to neutralise the higher oxidative load in these patients, who would thus need intakes which, with the exception of vitamin C and carotenes, are difficult to achieve solely by dietary means.

The categorical data are presented as counts and percentages. Height and weight were recorded and a blood sample of the fasting patient was drawn and conducted around the same time for all participants early morning, around 8: This difference remained significant after adjustment for alcohol and dietary intakes.

Material and methods Blood samples Total blood antioxidants were measured in serum of healthy individuals, 55 male and 91 female, living in the same region and were classified in three groups based on their age; A: The participants were fully informed about the purpose and content of the experiment and their informed consent of participation were obtained.

The results were given as a percentage of the total fatty acid composition. Plasma and erythrocyte magnesium were measured by atomic absorption spectrometry Varian Spectra AAS. Diabetic patients had lower glutathione 5.

Abstract Background: These results imply that a diet rich in antioxidants based on antioxidant rich food consumption and not on single antioxidants administration, can increase the antioxidant status of the organism and offer better health.

Administration of synthetic antioxidants as dietary supplements does not seem to have the same beneficial effect as consumption of the same antioxidants as part of food ingredients. At the first interview, the participants were informed about the objectives and procedures of study and signed a written consent form.

In our sample of French men, smoking had an adverse effect on antioxidant status; vitamin intakes were reduced in smokers and plasma antioxidant indexes were altered independently of dietary intakes. As a consequence of any one of these mechanisms, the lower concentrations of omega-3 PUFAs could affect neurotransmission in several ways in the central nervous system.

Oxidative stress status in patients with diabetes mellitus: relationship to diet

A dietary deficiency of omega-3 may be associated with an increased risk of smoking [ 13 ]. Thus, it still remains to be unequivocally proven that increasing antioxidant consumption will reduce the incidence of atherosclerosis. Kenneth R. The total serum antioxidant status increases with age and this fact should be taken into account when TAC is measured in different diseases.

The influence of factors such as age, sex, life style and smoking on oxidative stress status of the organism remains unclear.

Plasma alpha-tocopherol, ascorbic acid, and carotenoids were measured as antioxidants and malondialdehyde, protein Schiff bases, and autoantibodies against malondialdehyde-protein adducts as oxidative stress indexes.

However, in another trial, DHA supplementation given to a small number of smokers for only a few weeks, in a low dosage, without a control group did not show reduction in the number of smoked cigarettes during the treatment period [ 19 ]. Correlation between TAC and age Factors such as smoking and physical activity which can influence the total antioxidant capacity were similar in all subjects.

Among the measured oxidative stress indexes, only Schiff base concentration was positively related to the number of cigarettes smoked. Effect of metabolic status on OSS The relationship between OSS and metabolic status was analysed in both diabetic and nondiabetic subjects.

The effects of age and diet on antioxidant capacity have not investigated sufficiently up to date in Greece. Several considerations should be taken into account when interpreting our observations. There was no significant difference in the intake of other foods rich in alpha-linolenic acid, as shrimp, squid, sushi, flaxseed, nuts, oilseeds and granola.

Patients taking more than two or three portions of fruit daily nine out of 30 were only distinguished by having lower plasma MDA 0.Research Article Diet Quality and Its Relationship with Antioxidant Status in Patients with Rheumatoid Arthritis AnnaPrescha,1 KatarzynaZabłocka-Słowińska,1 SylwiaPłaczkowska,2 DaivaGorczyca,3Author: Anna Prescha, Katarzyna Zabłocka-Słowińska, Sylwia Płaczkowska, Daiva Gorczyca, Anna Łuczak, Marceli.

The French smoking study is reviewed in the context of overwhelming evidence in smokers for oxidative damage to lung tissues, the relative roles of poor dietary habit and alcohol use, and.

Original Article Singapore Med J ; 50(6): Antioxidant status and smoking habits: relationship with diet Jain A, Agrawal B K, Varma M, Jadhav A A. Introduction: The present study was conducted to assess the association between smoking, dietary intake of antioxidants and plasma indices of oxidative stress and antioxidant defences in male smokers (cigarette and bidi smokers).

Methods: The study sample consisted of healthy men, including 50 non-smokers and 50 smokers, who were Cited by: The present study was designed to investigate teh relationship between smoking and antioxidant nutriennt intake and status.

Smoker (n 44) and non-smoker (n 44) male students attending Dhake University, aged between 22 and 28 years and living in a University Hall of Residence, were selected for the present by:
