News & Research:

Red Meat Tied to Increased Mortality Risk - ABC News, 3/12/12 - "The study, which followed more than 120,000 American men and women, linked daily consumption of unprocessed red meat with a 13 percent increase in mortality risk ... A daily serving of processed meat carried an even bigger risk. Eating one hotdog or two strips of bacon per day was associated with a 20 percent increased risk of death ... The study could not conclude that red meat consumption caused the increased risk of death, rather that there was an association between the two. But red meat contains compounds known to boost the risk of cardiovascular disease and cancer, such as saturated fat, sodium nitrites and other "chemicals produced during processing and cooking," ... Swapping red meat for healthy protein sources, such as poultry, fish, legumes and whole grains was linked to a decrease in mortality risk, ranging from 7 percent for fish to 19 percent for nuts"
Processed and Unprocessed Red Meat Consumption and Incident Type 2 Diabetes Among French Women - Diabetes Care. 2011 Nov 18 - "Comparing the highest category of processed meat intake, ≥5 servings/week (median, 48 g/day), to the lowest, <1 serving/week (median, 5 g/day), processed meat was significantly associated with incident diabetes (hazard ratio 1.30 [95% CI 1.07-1.59], P trend = 0.0007; for 1 serving/day, 1.29 [1.14-1.45]). Unprocessed red meat was not associated with diabetes"
Health risk from eating well-done meat may be underestimated - Science Daily, 11/1/11 - "the incidence of intestinal tumours increased from 31 per cent to 80 per cent in "human-like" mice who consumed substances from meat crust (i.e. the surface formed during heat-treatment) ... Heat-processing of food can lead to the formation of carcinogenic substances. The formation of carcinogenic substances -- so-called food mutagens -- usually occurs at high temperatures when frying or grilling"
Red meat linked to increased risk of type 2 diabetes - Science Daily, 8/10/11 - "After adjusting for age, body mass index (BMI), and other lifestyle and dietary risk factors, the researchers found that a daily 100-gram serving of unprocessed red meat (about the size of a deck of cards) was associated with a 19% increased risk of type 2 diabetes. They also found that one daily serving of half that quantity of processed meat -- 50 grams (for example, one hot dog or sausage or two slices of bacon) -- was associated with a 51% increased risk ... Clearly, the results from this study have huge public health implications given the rising type 2 diabetes epidemic and increasing consumption of red meats worldwide ... for an individual who eats one daily serving of red meat, substituting one serving of nuts per day was associated with a 21% lower risk of type 2 diabetes; substituting low-fat dairy, a 17% lower risk; and substituting whole grains, a 23% lower risk ... consumption of processed red meat -- like hot dogs, bacon, sausage, and deli meats, which generally have high levels of sodium and nitrites -- should be minimized and unprocessed red meat should be reduced. If possible, they add, red meat should be replaced with healthier choices, such as nuts, whole grains, low-fat dairy products, fish, or beans"
Strong Evidence Links Meat to Higher Risk for Colon Cancer - Medscape, 5/30/11 - "For red and processed meat, the findings from 10 new studies were added to the 14 studies that were evaluated in the 2007 report. From these 24 studies, the panel confirmed that there is convincing evidence that both red and processed meat can increase the risk for colorectal cancer ... The WCRF/AICR recommend that the consumption of red meat be limited to 500 g/week, which is roughly the equivalent of 5 or 6 medium portions of beef, lamb, or pork. They also recommend that processed meat be avoided ... According to their data, if 3.5 ounces of red meat are consumed every day (24.5 ounces per week), the risk for colorectal cancer will be 17% higher than if no red meat is consumed. If the amount of red meat consumed is doubled (7.0 ounces every day; 49 ounces per week), the risk is 34% higher. However, the evidence found that there was very little increase in risk for individuals who ate less than 18 ounces of red meat per week ... The cancer risk associated with processed meat, which includes ham, bacon, pastrami, hot dogs, and sausages, was much higher. Consuming 3.5 ounces every day (24.5 ounces per week) was associated with a risk that is 36% higher than the risk of consuming no processed meat. As with red meat, the higher the rate of consumption, the higher the risk for colorectal cancer"
Certain meat components may increase bladder cancer risk, study suggests - Science Daily, 8/2/10 - "People whose diets had the highest amount of total dietary nitrite (from all sources and not just from meat), as well as those whose diets had the highest amount of nitrate plus nitrite from processed meats had a 28 percent to 29 percent increased risk of developing bladder cancer compared with those who consumed the lowest amount of these compounds"
Eating processed meats, but not unprocessed red meats, may raise risk of heart disease and diabetes, study finds - Science Daily, 5/17/10 - "eating processed meat, such as bacon, sausage or processed deli meats, was associated with a 42% higher risk of heart disease and a 19% higher risk of type 2 diabetes. In contrast, the researchers did not find any higher risk of heart disease or diabetes among individuals eating unprocessed red meat, such as from beef, pork, or lamb"
Meat, especially if it's well done, may increase risk of bladder cancer - Science Daily, 4/19/10
Good Diet May Aid Ovarian Cancer Survival - WebMD, 3/4/10 - "five years, 75% of the women who ate less than one serving a week of yellow vegetables were alive, compared to about 82% of those who had three or more servings of yellow vegetables a week ... When the researchers looked at red meat lovers vs. avoiders, "we found almost a threefold risk of dying for those women who ate four or more servings of red meat a week compared to those who ate less than one serving per week over the 11-year study period"

Meat consumption in relation to mortality from cardiovascular disease among Japanese men and women - Eur J Clin Nutr. 2012 Feb 15 - "Moderate meat consumption, up to ~ 100 g/day, was not associated with increased mortality from ischemic heart disease, stroke or total cardiovascular disease among either gender"
Meat Consumption, Cooking Methods, Mutagens, and Risk of Squamous Cell Carcinoma of the Esophagus: A Case-Control Study in Uruguay - Nutr Cancer. 2012 Jan 13 - "Red meat, lamb, and boiled meat were directly associated with the risk of ESCC, whereas total white meat, poultry, fish, and liver were mainly protective against this malignancy"
Dietary Protein Sources and the Risk of Stroke in Men and Women - Stroke. 2011 Dec 29 - "During 26 and 22 years of follow-up in women and men, respectively, we documented 2633 and 1397 strokes, respectively. In multivariable analyses, higher intake of red meat was associated with an elevated risk of stroke, whereas a higher intake of poultry was associated with a lower risk. In models estimating the effects of exchanging different protein sources, compared with 1 serving/day of red meat, 1 serving/day of poultry was associated with a 27% (95% CI, 12%-39%) lower risk of stroke, nuts with a 17% (95% CI. 4%-27%) lower risk, fish with a 17% (95% CI, 0%-30%) lower risk, low-fat dairy with an 11% (95% CI, 5%-17%) lower risk, and whole-fat dairy with a 10% (95% CI, 4%-16%) lower risk. We did not see significant associations with exchanging legumes or eggs for red meat"
Diet and the risk of head and neck cancer: a pooled analysis in the INHANCE consortium - Cancer Causes Control. 2011 Oct 29 - "We investigated the association between diet and head and neck cancer (HNC) risk using data from the International Head and Neck Cancer Epidemiology (INHANCE) consortium. The INHANCE pooled data included 22 case-control studies with 14,520 cases and 22,737 controls ... An inverse association was observed for higher-frequency intake of fruit (4th vs. 1st quartile OR = 0.52, 95% CI = 0.43-0.62, p (trend) < 0.01) and vegetables (OR = 0.66, 95% CI = 0.49-0.90, p (trend) = 0.01). Intake of red meat (OR = 1.40, 95% CI = 1.13-1.74, p (trend) = 0.13) and processed meat (OR = 1.37, 95% CI = 1.14-1.65, p (trend) < 0.01) was positively associated with HNC risk"
Dietary patterns and risk of oesophageal cancers: a population-based case-control study - Br J Nutr. 2011 Sep 7:1-10 - "We conducted a population-based case-control study, which included 365 oesophageal adenocarcinoma (OAC), 426 oesophagogastric junction adenocarcinoma (OGJAC) and 303 oesophageal squamous cell carcinoma (OSCC) cases, with frequency matched on age, sex and geographical location to 1580 controls ... A high score on the meat-and-fat pattern was associated with increased risk of all three cancers: multivariable-adjusted OR 2.12 (95 % CI 1.30, 3.46) for OAC; 1.88 (95 % CI 1.21, 2.94) for OGJAC; 2.84 (95 % CI 1.67, 4.83) for OSCC (P-trend < 0.01 for all three cancers). A high score on the pasta-and-pizza pattern was inversely associated with OSCC risk (OR 0.58, 95 % CI 0.36, 0.96, P for trend = 0.009); and a high score on the fruit-and-vegetable pattern was associated with a borderline significant decreased risk of OGJAC (OR for Q4 v. Q1 0.66, 95 % CI 0.42, 1.04, P = 0.07) and significantly decreased risk of OSCC (OR 0.41, 95 % CI 0.24, 0.70, P for trend = 0.002). High-fat dairy foods appeared to play a dominant role in the association between the meat-and-fat pattern and risk of OAC and OGJAC"
Meat Consumption and Risk of Lung Cancer Among Never-Smoking Women - Nutr Cancer. 2011 Jul 20 - "Among these never smokers, fruit and vegetable intake were inversely associated with lung cancer risk. Seventy-two percent of meat consumed was white meat (chicken or fish). Meat consumption overall was inversely associated with lung cancer [adjusted odds ratio (OR), 0.88, 0.59 for second, third tertiles, P (trend) = .012]. An inverse relationship between fish consumption and lung cancer (adjusted OR, 0.81, 0.47 for 2nd, 3rd tertiles, P (trend) < .001) was observed. No association was seen between consumption of processed meats and lung cancer, nor between dietary heterocyclic amines and lung cancer. Our data suggest that fish consumption may be protective against lung cancer in never smokers"
Red meat consumption and risk of stroke in Swedish men - Am J Clin Nutr. 2011 Jun 8 - "mean follow-up of 10.1 y ... Consumption of processed meat, but not of fresh red meat, was positively associated with risk of stroke. The multivariable relative risks (RRs) of total stroke for the highest compared with the lowest quintiles of consumption were 1.23 (95% CI: 1.07, 1.40; P for trend = 0.004) for processed meat and 1.07 (95% CI: 0.93, 1.24; P for trend = 0.77) for fresh red meat. Processed meat consumption was also positively associated with risk of cerebral infarction in a comparison of the highest with the lowest quintile (RR: 1.18; 95% CI: 1.01, 1.38; P for trend = 0.03)"
Dietary fat and meat intakes and risk of reflux esophagitis, Barrett's esophagus and esophageal adenocarcinoma - Int J Cancer. 2011 Mar 31 - "The aim of this study was to investigate whether dietary fat and meat intakes are associated with reflux esophagitis (RE), Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) ... Patients in the highest quartile of total fat intake had a higher risk of RE (OR=3.54; 95%CI=1.32-9.46) and EAC (OR=5.44; 95%CI=2.08-14.27). A higher risk of RE and EAC was also reported for patients in the highest quartile of saturated fat intake (OR=2.79; 95%CI=1.11-7.04; OR=2.41; 95%CI=1.14-5.08, respectively) and monounsaturated fat intake (OR=2.63; 95%CI=1.01-6.86; OR=5.35; 95%CI=2.14-13.34, respectively). Patients in the highest quartile of fresh red meat intake had a higher risk of EAC (OR=3.15; 95%CI=1.38-7.20). Patients in the highest category of processed meat intake had a higher risk of RE (OR=4.67; 95%CI=1.71-12.74). No consistent associations were seen for BE with either fat or meat intakes"- Whoa!!! Up to 5 times the risk of esophageal adenocarcinoma for the highest processed meat intake!!!
Association between red meat consumption and metabolic syndrome in a Mediterranean population at high cardiovascular risk: Cross-sectional and 1-year follow-up assessment - Nutr Metab Cardiovasc Dis. 2010 Sep 26 - "Subjects in the upper quartile of RM consumption were more likely to meet the criteria for the MetS at baseline (OR, 2.3; 95% CI, 1.4-3.9; P-trend = 0.001) and after 1-year follow-up (OR, 2.2; 95% CI, 1.3-3.7; P-trend = 0.034) compared with those in the quartile of reference, even after adjusting for potential confounders. The longitudinal analyses showed that individuals in the fourth quartile of RM consumption had an increased risk of MetS (OR, 2.7; 95% CI, 1.1-6.8; P-trend = 0.009) or central obesity incidence (OR, 8.1; 95% CI, 1.4-46.0; P-trend = 0.077) at the end of the follow-up compared to the lowest quartile"
AMACR polymorphisms, dietary intake of red meat and dairy and prostate cancer risk - Prostate. 2010 Oct 13 - "Red meat consumption was positively associated with PCa risk, and the association was stronger for more aggressive disease (lowest vs. highest tertile OR = 1.55"
Association between red meat consumption and metabolic syndrome in a Mediterranean population at high cardiovascular risk: Cross-sectional and 1-year follow-up assessment - Nutr Metab Cardiovasc Dis. 2010 Sep 26 - "Subjects in the upper quartile of RM consumption were more likely to meet the criteria for the MetS at baseline (OR, 2.3; 95% CI, 1.4-3.9; P-trend = 0.001) and after 1-year follow-up (OR, 2.2; 95% CI, 1.3-3.7; P-trend = 0.034) compared with those in the quartile of reference, even after adjusting for potential confounders. The longitudinal analyses showed that individuals in the fourth quartile of RM consumption had an increased risk of MetS (OR, 2.7; 95% CI, 1.1-6.8; P-trend = 0.009) or central obesity incidence (OR, 8.1; 95% CI, 1.4-46.0; P-trend = 0.077) at the end of the follow-up compared to the lowest quartile"
Major Dietary Protein Sources and Risk of Coronary Heart Disease in Women - Circulation. 2010 Aug 16 - "26 years of follow-up ... higher intakes of red meat, red meat excluding processed meat, and high-fat dairy were significantly associated with elevated risk of CHD. Higher intakes of poultry, fish, and nuts were significantly associated with lower risk. In a model controlling statistically for energy intake, 1 serving per day of nuts was associated with a 30% (95% confidence interval, 17% to 42%) lower risk of CHD compared with 1 serving per day of red meat. Similarly, compared with 1 serving per day of red meat, a lower risk was associated with 1 serving per day of low-fat dairy (13%; 95% confidence interval, 6% to 19%), poultry (19%; 95% confidence interval, 3% to 33%), and fish (24%; 95% confidence interval, 6% to 39%). Conclusions-These data suggest that high red meat intake increases risk of CHD and that CHD risk may be reduced importantly by shifting sources of protein in the US diet"
Red meat consumption and risk of heart failure in male physicians - Nutr Metab Cardiovasc Dis. 2010 Jul 30 - "there was a positive and graded relation between red meat consumption and HF [hazard ratio (95% CI) of 1.0 (reference), 1.02 (0.85-1.22), 1.08 (0.90-1.30), 1.17 (0.97-1.41), and 1.24 (1.03-1.48) from the lowest to the highest quintile of red meat, respectively"
Associations of red meat, fat, and protein intake with distal colorectal cancer risk - Nutr Cancer. 2010 Aug;62(6):701-9 - "There was no association between total, saturated, or monounsaturated fat and distal CRC risk. In African Americans, the OR of distal CRC for the highest category of polyunsaturated fat intake was 0.28 (95% CI = 0.08-0.96). The percent of energy from protein was associated with a 47% risk reduction in Whites (Q4 OR = 0.53, 95% CI = 0.37-0.77). Red meat consumption in Whites was associated with a marginally significant risk reduction (Q4 OR = 0.66, 95% CI = 0.43-1.00). Our results do not support the hypotheses that fat, protein, and red meat increase the risk of distal CRC"
Intakes of meat, fish, poultry, and eggs and risk of prostate cancer progression - Am J Clin Nutr. 2009 Dec 30 - "Intakes of processed and unprocessed red meat, fish, total poultry, and skinless poultry were not associated with prostate cancer recurrence or progression. Greater consumption of eggs and poultry with skin was associated with 2-fold increases in risk in a comparison of extreme quantiles: eggs [hazard ratio (HR): 2.02; 95% CI: 1.10, 3.72; P for trend = 0.05] and poultry with skin (HR: 2.26, 95% CI: 1.36, 3.76; P for trend = 0.003). An interaction was observed between prognostic risk at diagnosis and poultry. Men with high prognostic risk and a high poultry intake had a 4-fold increased risk of recurrence or progression compared with men with low/intermediate prognostic risk and a low poultry intake (P for interaction = 0.003). CONCLUSIONS: Our results suggest that the postdiagnostic consumption of processed or unprocessed red meat, fish, or skinless poultry is not associated with prostate cancer recurrence or progression, whereas consumption of eggs and poultry with skin may increase the risk"
Dietary iron intake and risk of endometrial cancer: a population-based case-control study in Shanghai, China - Nutr Cancer. 2010;62(1):40-50 - "Dietary red meat and animal fat have been linked to endometrial cancer (EC) risk, but the impact of bioavailable iron in animal-derived foods has been less well studied ... Animal-derived iron intake was positively associated with EC risk [adjusted OR = 1.9; 95% CI = 1.4-2.7, P(trend) < 0.01, highest vs. lowest quartile], predominantly after menopause (OR = 2.2; 95%CI = 1.4-3.4, P(trend) < 0.01) and in women with BMI >or= 25 kg/m(2)(OR = 3.2; 95% CI = 1.4-7.5 in postmenopausal obese women, P(trend) < 0.01). Animal-derived fat was also associated with postmenopausal EC risk (OR = 1.7; 95% CI = 1.2-2.5, P(trend) < 0.01). Multiplicative interactions between animal-derived iron and BMI or animal-derived fat intake were not observed. Animal-derived iron intake is associated with increased risk of EC after menopause and among obese women. Avoidance of animal-derived (heme) iron may reduce the risk of EC in these women"
