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

/ SupremeCmdr / Leave a comment

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.

Consumption of ultra-processed foods and cancer risk: results from NutriNet-Santé prospective cohort

/ SupremeCmdr / Leave a comment

Conclusions – In this large prospective study, a 10% increase in the proportion of ultra-processed foods in the diet was associated with a significant increase of greater than 10% in risks of overall and breast cancer. Further studies are needed to better understand the relative effect of the various dimensions of processing (nutritional composition, food additives, contact materials, and neoformed contaminants) in these associations.

We categorized all food and drink items of the NutriNet-Santé composition table into one of the four food groups in NOVA, a food classification system based on the extent and purpose of industrial food processing.94243 This study primarily focused on the “ultra-processed foods” NOVA group. This group includes mass produced packaged breads and buns; sweet or savory packaged snacks; industrialized confectionery and desserts; sodas and sweetened drinks; meat balls, poultry and fish nuggets, and other reconstituted meat products transformed with addition of preservatives other than salt (for example, nitrites); instant noodles and soups; frozen or shelf stable ready meals; and other food products made mostly or entirely from sugar, oils and fats, and other substances not commonly used in culinary preparations such as hydrogenated oils, modified starches, and protein isolates. Industrial processes notably include hydrogenation, hydrolysis, extruding, moulding, reshaping, and pre-processing by frying. Flavouring agents, colours, emulsifiers, humectants, non-sugar sweeteners, and other cosmetic additives are often added to these products to imitate sensorial properties of unprocessed or minimally processed foods and their culinary preparations or to disguise undesirable qualities of the final product.

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.

Cashew Nut Consumption Increases HDL Cholesterol and Reduces Systolic Blood Pressure in Asian Indians with Type 2 Diabetes: A 12-Week Randomized Controlled Trial

This explains why cashews are my favorite nut.

I’m the guy who picks out all of the cashews in a bowl of mixed nuts.

Linking Sucrose to Hyperlipidemia and Cancer

In rats.  But it’s the behavior of the sugar industry rats that is more disturbing.

Our study contributes to a wider body of literature documenting industry manipulation of science. Industries seeking to influence regulation have a history of funding research resulting in industry-favorable interpretations of controversial evidence related to health effects of smoking [15,16], therapeutic effects of pharmaceutical drugs [17,18], the relationship between sugar-sweetened beverage consumption and weight gain or obesity [5], and the causes of climate change, [19] among other issues. The tobacco industry also has a long history of conducting research on the health effects of its products that is often decades ahead of the general scientific community and not publishing results that do not support its agenda [20–23]. This paper provides empirical data suggesting that the sugar industry has a similar history of conducting, but not publishing studies with results that are counter to its commercial interests.

Disparities in State-Specific Adult Fruit and Vegetable Consumption — United States, 2015

/ SupremeCmdr / Leave a comment

Recent data show adults continue to consume too few fruits and vegetables; overall, 12.2% met fruit intake recommendations and 9.3% met vegetable intake recommendations during 2015. Consumption was lower among men, young adults, and adults with greater poverty, and varied by state. Among subgroups, the largest disparities in meeting the recommendation for fruit intake was by sex (15.1% among women compared with 9.2% among men), while the largest disparities in meeting the recommendation for vegetable intake was by poverty (11.4% among adults in the highest household income category compared with 7.0% among adults below or close to the poverty level).

Lose Weight on a Veg Diet

/ SupremeCmdr / Leave a comment

If you’re trying to lose weight, there are tons of diets to choose from—and new research points to vegetarian diets as a promising option. For the study, which was published in the Journal of the American College of Nutrition, 74 participants cut their normal daily calories by 500 for six months. Some went on a vegetarian diet, and some went on a diabetes-friendly diet (one that focuses on reducing sugars, refined carbs, cholesterol, and saturated fat). People on the vegetarian diet lost more subcutaneous fat (that’s the noticeable fat under your skin). They also lost more subfascial fat (the type that lines your muscles) and intramuscular fat (the type stored inside your muscles). That’s important, since the fat that’s stored inside your muscles and organs can mess with your metabolism, potentially leading to insulin resistance and even type 2 diabetes, says study author Hana Kahleova, M.D.

I found the research quoted to be more interesting than the recipes.

Consumption of antioxidant-rich foods is associated with a lower risk of DM2

/ SupremeCmdr / Leave a comment

A lower risk of type 2 diabetes has been observed among individuals consuming food rich in antioxidants. This effect is largely contributed by fruit, vegetables, tea and other hot beverages, as well as moderate consumption of alcohol, as shown in a recent study from an Inserm research group, published in Diabetologia, the journal of the European Association for the Study of Diabetes (EASD).

Eating regular variety of nuts associated with lower risk of heart disease

/ SupremeCmdr / Leave a comment

People who regularly eat nuts, including peanuts, walnuts and tree nuts, have a lower risk of developing cardiovascular disease or coronary heart disease compared to people who never or almost never eat nuts, according to a new study. The study is the largest to date looking at frequency of nut consumption in relation to incident cardiovascular disease.

The study found a consistent inverse association between total nut consumption and total cardiovascular disease and coronary heart disease. Also, after looking at individual nut consumption, eating walnuts one or more times per week was associated with a 19 percent lower risk of cardiovascular disease and 21 percent lower risk of coronary heart disease. Participants who ate peanuts or tree nuts two or more times per week had a 13 percent and 15 percent lower risk of cardiovascular disease, respectively, and a 15 percent and 23 percent, lower risk of coronary heart disease, respectively, compared to those who never consumed nuts.

Participants who consumed five or more servings of nuts a week had a 14 percent lower risk of cardiovascular disease and a 20 percent lower risk of coronary heart disease than participants who never or almost never consumed nuts. The results were similar when accounting for consumption of tree nuts, peanuts and walnuts individually. Researchers found no evidence of an association between total nut consumption and risk of stroke, but eating peanuts and walnuts was inversely associated with the risk of stroke. Peanut butter and tree nuts were not associated with stroke risk.

So that bowl of nuts on the bar?  Yes, eat them.
