The efficacy of insulin in stimulating whole-body glucose disposal (insulin sensitivity) was quantified using direct methodology in thirty lacto-ovo vegetarians and in thirty meat-eaters. All subjects were adult, lean (BMI <23 kg/m2), healthy and glucose tolerant. Lacto-ovo vegetarians were more insulin sensitive than meat-eaters, with a steady-state plasma glucose (mmol/l) of 4·1 (95 % CI 3·5, 5·0) v. 6·9 (95 % CI 5·2, 7·5; P=0·0028) respectively. In addition, lacto-ovo vegetarians had lower…

TLDR
In healthy Chinese men, the lacto-vegetarian diet seems to exert protective effects on blood pressure, lipid profiles, and metabolic parameters and results in significantly lower carotid IMT, corresponding with lower cardiovascular risk points and probability of developing CVD in 5-10 years in vegetarians 24-55 years old.
Postmenopausal Vegetarians' Low Serum Ferritin Level May Reduce the Risk for Metabolic Syndrome
TLDR
Postmenopausal vegetarians had lower MetS presence and a lower serum ferritin level compared to non-vegetarians and vegetarians' low serum ferrisin level may reduce the risk of MetS in postmenopausal women.
Effect of Iron Depletion on Cardiovascular Risk Factors
TLDR
Although individuals at high risk for ASCVD are not Fe‐overloaded, they seem to benefit, metabolically and hemodynamically, from lowering of body Fe to levels commonly seen in premenopausal females.
Iron Deficiency in Vegetarian and Omnivorous Individuals: Analysis of 1340 Individuals
TLDR
The data show that nutritional status and inflammation levels affect ferritin levels and may interfere with the correct diagnosis of iron deficiency in both vegetarian and omnivorous individuals.
Iron stores, blood donation, and insulin sensitivity and secretion.
TLDR
Blood donation is simultaneously associated with increased insulin sensitivity and decreased iron stores, and not just in classic pathologic conditions associated with iron overload (hemochromatosis and hemosiderosis).
Taiwanese Vegetarians and Omnivores: Dietary Composition, Prevalence of Diabetes and IFG
TLDR
A strong protective association between Taiwanese vegetarian diet and diabetes/IFG is found, after controlling for various potential confounders and risk factors.
An oily fish diet increases insulin sensitivity compared to a red meat diet in young iron-deficient women
TLDR
An increase in oily fish consumption increases insulin sensitivity in young iron-deficient women, and this outcome should be considered when giving dietary advice to this population.
Ferritin and Soluble Transferrin Receptors in Type 2 Diabetic and Non-diabetic Post-menopausal Women in Dhaka, Bangladesh.
TLDR
A higher level of sTfR and a lower level of hemoglobin in diabetic cases is suggestive of iron deficiency anaemia rather than iron overload, while iron indices of non-diabetic women were within the normal range.
The effect of vegetarian diets on iron status in adults: A systematic review and meta-analysis
TLDR
It is recommended that not only vegetarians but also non-vegetarians should regularly control their iron status and improve their diet regarding the content and bioavailability of iron by consuming more plants and less meat.
Elevated serum ferritin concentrations in prediabetic subjects
TLDR
Aelevation in serum ferritin can be seen in pre-diabetes stage, before the occurrence of an overt diabetes mellitus, based on the data from this study.

Increased insulin sensitivity in iron-deficient rats.
TLDR
The data indicate that insulin sensitivity is increased in ID rats and that ID rats cannot metabolize exogenous insulin as well as C rats.
Hepatic glucose production and insulin sensitivity and responsiveness in iron-deficient anemic rats.
TLDR
It is concluded that increased glucose utilization rates in IDA rats are due primarily to an increase in peripheral insulin responsiveness, and the effect of IDA on insulin sensitivity and responsiveness is evaluated.
Body Iron Stores Are Associated With Serum Insulin and Blood Glucose Concentrations: Population study in 1,013 eastern Finnish men
TLDR
Mildly elevated body iron stores are associated with statistically significant elevations in glucose homeostasis indexes, and this association isomersally significant in middle-aged men.
Iron status of premenopausal women in a university community and its relationship to habitual dietary sources of protein.
TLDR
Form rather than amount of dietary Fe appears to be most influential on Fe status; the basis for the distinctly lower Fe stores among heavy users of fish and/or poultry remains to be determined.
Long-term effects of a vegetarian diet on the nutritional status of elderly people (Dutch Nutrition Surveillance System).
TLDR
The results indicate that in comparison to omnivorous elderly the vegetarian elderly have aged successfully with respect to cardiovascular risk factors, and vegetarian elderly are at a higher risk for a marginal iron, zinc, and vitamin B12 status.
Iron and zinc status of young women aged 14 to 19 years consuming vegetarian and omnivorous diets.
TLDR
SuboptimalIron and zinc status was attributed to low intakes of poorly available iron and zinc in all dietary groups.
A vegetarian diet rich in soybean products compromises iron status in young students.
TLDR
It is concluded that a vegetarian diet that is rich in soybean products and restricted in animal foods is limited in bioavailable iron and is not adequate for maintaining iron balance in men and women.
Iron status in exercising women: the effect of oral iron therapy vs increased consumption of muscle foods.
TLDR
Iron status in the 50 FE + EX and M + EX groups improved after week 4 as indicated by an increase in serum ferritin, serum iron, and hemoglobin concentrations, and a decline in total iron-binding capacity, which was offset to varying degrees by ingesting iron or meat supplements.
Relation between iron stores and non-insulin dependent diabetes in men: case-control study
TLDR
It was found that fasting concentrations of serum insulin and blood glucose were raised in men with high serum concentrations of ferritin (an indication of raised stores of iron), and formation of hydroxyl radicals catalysed by iron may play an important part in the development of diabetes.
Absorption of iron from Western-type lunch and dinner meals.
TLDR
The absorption of nonheme iron was measured from 20 lunch and dinner meals, in 187 subjects with varying iron status, and the relative role of meat/fish and ascorbic acid in stimulating the absorption was studied by adding or subtracting single food components.
