Nutritional and health benefits of dried beans

 

Mortality

Bean consumption has been associated with reduced risk of mortality, although only limited data on this endpoint are available. The Food Habits in Later Life Study followed nearly 800 older men and women for 7 y, during which time 169 participants died (61). Among the 5 populations evaluated, mean legume intake ranged from ~85 g/d in Japan and Greece to a low of only 14 g/d in some segments of the Australian population. Of all of the food groups studied, legumes were the only foods associated with a reduced risk of mortality: the RR was 0.92 (95% CI: 0.85, 0.99) for every 20 g consumed. Dried beans were not assessed separately in this study, although other than in Japan, soybean intake would be negligible among the populations in this survey.

This study was published in 2014 and contains a wealth of information.  The online and PDF copies of the study are here.

Because populations in recent decades have adopted more Western-style diets, however, dried bean consumption has seen a decline. For example, between the 1960s and 1990s, dried bean intake decreased by 40% in India and by 24% in Mexico.

Bean consumption down, obesity up.  Hmmm……

Vegan Diet, Subnormal Vitamin B-12 Status and Cardiovascular Health

Abstract

Vegetarian diets have been associated with atherosclerosis protection, with healthier atherosclerosis risk profiles, as well as lower prevalence of, and mortality from, ischemic heart disease and stroke. However, there are few data concerning the possible cardiovascular effects of a vegan diet (with no meat, dairy or egg products). Vitamin B-12 deficiency is highly prevalent in vegetarians; this can be partially alleviated by taking dairy/egg products in lact-ovo-vegetarians. However, metabolic vitamin B-12 deficiency is highly prevalent in vegetarians in Australia, Germany, Italy and Austria, and in vegans (80%) in Hong Kong and India, where vegans rarely take vitamin B-12 fortified food or vitamin B-12 supplements. Similar deficiencies exist in northern Chinese rural communities consuming inadequate meat, egg or dairy products due to poverty or dietary habits. Vascular studies have demonstrated impaired arterial endothelial function and increased carotid intima-media thickness as atherosclerosis surrogates in such metabolic vitamin B-12 deficient populations, but not in lactovegetarians in China. Vitamin B-12 supplementation has a favourable impact on these vascular surrogates in Hong Kong vegans and in underprivileged communities in northern rural China. Regular monitoring of vitamin B-12 status is thus potentially beneficial for early detection and treatment of metabolic vitamin B-12 deficiency in vegans, and possibly for prevention of atherosclerosis-related diseases.

Conclusions

Metabolic vitamin B-12 deficiency is prevalent in vegetarians and, in particular, in vegans. Those subjects with normal or relatively high salt intake may be associated with unhealthy early vascular changes in function and structure, which have not been well documented in the past. In individuals with subnormal vitamin B-12 status, vitamin B-12 supplementation may significantly improve such vascular changes. Regular monitoring of vitamin B-12 profile may thus be beneficial for early detection and treatment of metabolic vitamin B-12 deficiency, and possibly prevention of atherosclerosis-related diseases.

It’s not easy to overcome confirmation bias.  So my research often takes me to studies and articles that challenge my firmest held beliefs.  This literature review study does confirm one of my longest held beliefs.  Some of the sickest people I see are the shoppers in health food stores.

Take some B-12.  Or as this study demonstrates get your B-12  from dairy, meat, and fish and shellfish.

 

Eat Yogurt

Higher intakes of yogurt were associated with a 30 percent reduction in risk of myocardial infarction among the Nurses’ Health Study women and a 19 percent reduction in the Health Professionals Follow-Up Study men.

In both groups, participants consuming more than two servings a week of yogurt had an approximately 20 percent lower risks of major coronary heart disease or stroke during the follow-up period. When revascularization was added to the total cardiovascular disease outcome variable, the risk estimates were reduced for both men and women, but remained significant.

Higher yogurt intake in combination with an overall heart-healthy diet was associated with greater reductions in cardiovascular disease risk among hypertensive men and women.

The Effect of Animal Protein on the Kidneys

About one in eight of us now has chronic kidney disease—and most don’t even know it: About three-quarters of the millions of people affected are unaware that their kidneys are starting to fail. This is “particularly worrisome given that early identification provides an opportunity to slow the progression and alter the course of disease.”

Drink More Green Tea

Conclusion

This study suggests that the consumption of green tea ≥2 times/d is associated with a reduced risk of COPD in Korean populations.

Consuming Green Tea at Least Twice Each Day Is Associated with Reduced Odds of Chronic Obstructive Lung Disease in Middle-Aged and Older Korean Adults

Drink more green tea.

Especially if you’re an older Korean.

Eat More Cashews

Conclusion

Cashew nut supplementation in Asian Indians with T2DM reduced systolic blood pressure and increased HDL cholesterol concentrations with no deleterious effects on body weight, glycemia, or other lipid variables. This study was registered at the clinical trial registry of India as CTRI/2017/07/009022.

Eating insects might seem yucky, but they are nutritious and there is no reason you can’t

According to the United Nations, insects are part of the traditional diet of 2 billion people around the world, with 1,900 species considered both edible and a highly nutritious food source with healthy fats, protein, fiber, vitamins and essential minerals.

“It’s interesting that many people who like shrimp and lobster think insects are yucky,” she said. “But shellfish are kind of like underwater insects.”

I copied the title so don’t blame me for the bad grammar.  Read the source article if you don’t believe me.

Still yucky if you ask me.

Low Folate, Vitamin D Implicated in First-Episode Psychosis

 

Nutritional deficiencies, especially deficiencies in folate and vitamin D, are associated with first-episode psychosis (FEP), new research suggests.

Australian researchers found significantly lower levels of folate and vitamin D in patients with FEP, compared to healthy control persons. Limited evidence also suggested that serum levels of vitamin C were reduced in people with FEP.
