Consuming tree nuts may reduce risk of cardiovascular disease, new study finds

In continuation of my update on the usefulness of walnuts

A new study published in the American Journal of Clinical Nutrition found that consuming tree nuts, such as walnuts, may lower the risk of cardiovascular disease. After conducting a systematic review and meta-analysis of 61 controlled trials, one of the authors, Michael Falk, PhD, Life Sciences Research Organization, found that consuming tree nuts lowers total cholesterol, triglycerides, LDL cholesterol, and ApoB, the primary protein found in LDL cholesterol. These are key factors that are used to evaluate a person's risk of cardiovascular disease. Walnuts were investigated in 21 of the 61 trials, more than any other nut reviewed in this study.

"Our study results further support the growing body of research that tree nuts, such as walnuts, can reduce the risk of cardiovascular diseases," said Dr. Falk. "Tree nuts contain important nutrients such as unsaturated fats, protein, vitamins and minerals. Walnuts are the only nut that provide a significant amount (2.5 grams per one ounce serving) of alpha-linolenic acid (ALA), the plant-based form of omega-3s."

Omega-3 fatty acids improve cognitive flexibility in older adults at risk of late-onset Alzheimer's disease

A study of older adults at risk of late-onset Alzheimer's disease found that those who consumed more omega-3 fatty acids did better than their peers on tests of cognitive flexibility -- the ability to efficiently switch between tasks -- and had a bigger anterior cingulate cortex, a brain region known to contribute to cognitive flexibility.

 

[alpha-linolenic acid (ALA), an essential omega-3 fatty acid, (18:3Δ9c,12c,15c, which means a chain of 18 carbons with 3 double bonds on carbons numbered 9, 12, and 15)].

The analysis suggests, but does not prove, that consuming DHA and EPA, two omega-3 fatty acids found in fish, enhanced cognitive flexibility in these adults in part by beefing up the anterior cingulate cortex, the researchers report in the journal Frontiers in Aging Neuroscience.

"Recent research suggests that there is a critical link between nutritional deficiencies and the incidence of both cognitive impairment and degenerative neurological disorders, such as Alzheimer's disease," said University of Illinois neuroscience, psychology, and speech and hearing science professor Aron Barbey, who led the study with M.D./Ph.D. student Marta Zamroziewicz. "Our findings add to the evidence that optimal nutrition helps preserve cognitive function, slow the progression of aging and reduce the incidence of debilitating diseases in healthy aging populations."

The researchers focused on aspects of brain function that are sometimes overlooked in research on aging, Zamroziewicz said. "A lot of work in cognitive aging focuses on memory, but in fact cognitive flexibility and other executive functions have been shown to better predict daily functioning than memory does," she said.

"Executive function" describes processes like planning, reasoning, paying attention, problem solving, impulse control and task switching.

"These functions tend to decline earlier than other cognitive functions in aging," Zamroziewicz said.

The new research built on previous studies that found associations between omega-3 fatty acid consumption, cognitive flexibility and the size of the anterior cingulate cortex.

"There's been some work to show that omega-3 fatty acids benefit cognitive flexibility, and there's also been work showing that cognitive flexibility is linked to this specific brain region, the anterior cingulate. But there's been very little work actually connecting these pieces," Zamroziewicz said.

The new study focused on 40 cognitively healthy older adults between the ages of 65 and 75 who are carriers of a gene variant (APOE e4) that is known to contribute to the risk of developing late-onset Alzheimer's disease.

The researchers tested participants' cognitive flexibility, measured levels of the fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in their blood, and imaged their brains using MRI. Statistical analyses teased out the relationships between these factors.

"We wanted to confirm that higher omega-3 fatty acids related to better cognitive flexibility, and we did in fact see that," Zamroziewicz said. "We also wanted to confirm that higher omega-3 fatty acids related to higher volume in the anterior cingulate cortex, and we saw that. Finally, we were able to show that higher volume in the anterior cingulate cortex was an intermediary in the relationship between omega-3 fatty acids and cognitive flexibility."

Omega-3 could supplement anti-VEGF treatment in AMD

In continuation of my update on Omega 3 fatty acid

Pilot study findings suggest that taking omega-3 fatty acid supplements could increase the efficacy or reduce the needed frequency of anti-vascular endothelial growth factor(VEGF) treatment in patients with exudative age-related macular degeneration (AMD).

Researcher Flavio Rezende (University of Montreal, Quebec, Canada) and co-workers say that 5–10% of patients with wet AMD lose three lines or more of visual acuity, despite treatment, and that more frequent anti-VEGF injections are associated with side effects.

New combination drug controls tumor growth, metastasis in mice...

Researchers at UC Davis, University of      Massachusetts  and Harvard  Medical  School  have
created a combination drug that controls both tumor growth and metastasis. By combining a COX-2 inhibitor, similar to Celebrex, and an epoxide hydrolase (sEH) inhibitor, the drug controls angiogenesis (blood vessel formation), limiting a tumor's ability to grow and spread. The study appears today in the journal Proceedings of the National Academy of Sciences.

"We've   been   studying  the  effects of  COX  and  sEH  inhibitors, both    by themselves  and in combination, for several years," said senior author and UC Davis Distinguished Professor Bruce Hammock. "We were surprised to find that the dual inhibitor was more active than higher doses of each compound, either individually or together. By combining the two molecules into one we got much greater potency against several diseases and completely unique effects in terms of blocking tumor growth and metastasis."

Both COX and sEH enzymes control lipid signaling, which has long been associated with inflammation, cell migration, proliferation, hypertension and other processes. COX inhibitors block production of inflammatory and pain-inducing lipids, while sEH inhibitors preserve anti-hypertensive, anti-inflammatory and analgesic compounds. Separate COX and sEH inhibitors were previously found to work together in reducing inflammation and neuropathic pain.

After testing individual COX-2 and sEH inhibitors, the team synthesized the drug (PTUTB), the first combined COX-2/sEH inhibitor. They then tested the dual inhibitor against human lung and breast tumors, both in vitro and in mice. They found that PTUTB blocked angiogenesis, inhibiting the proliferation of endothelial cells, which are critical to blood vessel formation. This in turn limited tumor growth and metastasis, reducing lung and breast tumor growth by 70 to 83 percent. 

In breast and lung cancers, the dual inhibitor blocked angiogenesis, which blocked the growth of solid tumors," said Hammock. "This represents a new mechanism to control blood vessel and tumor growth."

Robert Weiss, a co-author and professor of nephrology at UC Davis, added that the combination drug achieved the results with minimal side effects and no cardiovascular or gastrointestinal effects.

"This is particularly important when administering COX-2 inhibitors, which have well-known cardiovascular risks," he said. "However, the added sEH  inhibitor appears to block COX-2's side effects."

The research was initiated by first author Guodong Zhang when he was a postdoctoral fellow in the Hammock laboratory. Zhang previously demonstrated that sEH inhibitors improve the power of omega-3 fatty acid (fish oil) diets to reduce tumor growth and metastasis, and implicated epoxides of the dietary supplement DHA as the causative agent.

Low-fat fish oil changes cancer tissue in prostate cancer, study shows

Men with prostate cancer who ate a low-fat diet and took fish oil supplements had lower levels of pro-inflammatory substances in their blood and a lower cell cycle progression score, a measure used to predict cancer recurrence, than men who ate a typical Western diet, UCLA researchers found.

"We found that CCP scores were significantly lower in the prostate cancer in men who consumed the low-fat fish oil diet as compare to men who followed a higher fat Western diet," Aronson said. "We also found that men on the low-fat fish oil diet had reduced blood levels of pro-inflammatory substances that have been associated with cancer."

This study appears in the early online edition of Cancer Prevention Research, a peer-reviewed journal of the American Association for Cancer Research.

This study is a follow-up to a 2011 study by Aronson and his team that found a low-fat diet with fish oil supplements eaten for four to six weeks prior to prostate removal slowed the growth of cancer cells in human prostate cancer tissue compared to a traditional, high-fat Western diet.

That short-term study also found that the men on the low-fat fish oil diet were able to change the composition of their cell membranes in both the healthy cells and the cancer cells in the prostate. They had increased levels of omega-3 fatty acids from fish oil and decreased levels of the more pro-inflammatory omega-6 fatty acids from corn oil in the cell membranes, which may directly affect the biology of the cells, Aronson said.

"These studies are showing that, in men with prostate cancer, you really are what you eat," Aronson said. "The studies suggest that by altering the diet, we may favorably affect the biology of prostate cancer."

Fish Oil Pills Might Cut Diabetes Risk....

Supplements, also known as omega-3 fatty acids, increase levels of a hormone called adiponectin that's linked to insulin sensitivity, Harvard researchers found. Higher levels of this hormone in the bloodstream have also been linked to a lower risk for heart disease.

"While prior animal studies found fish oil increased circulating adiponectin, whether similar effects apply in humans is not established," the study's lead author, Jason Wu, from the Harvard School of Public Health, said in a news release from the Endocrine Society.

For their study, the researchers conducted a "meta-analysis" of 14 clinical trials. A meta-analysis reviews existing research and attempts to find a consistent pattern. In this case, the studies that were reviewed were all randomized, placebo-controlled trials, which is considered the gold standard in research.

"By reviewing evidence from existing randomized clinical trials, we found that fish oil supplementation caused modest increases in adiponectin in the blood of humans," Wu explained.

Overall, the new study looked at 682 people who took fish oil supplements, and 641 who were given placebos such as sunflower or olive oil.

Among the people treated with fish oil, adiponectin levels increased by 0.37 micrograms per milliliter of blood. This hormone plays a beneficial role in processes that affect metabolism, such as blood sugar regulation and inflammation.

Because the effects of fish oil varied significantly in the studies analyzed, the researchers suggested that omega-3 fatty acids could have a stronger effect in certain groups of people. The investigators concluded that more research is needed to determine which people would benefit most from fish oil supplements.

"Although higher levels of adiponectin in the bloodstream have been linked to lower risk of diabetes and coronary heart disease, whether fish oil influences glucose [blood sugar] metabolism and development of type 2 diabetes remains unclear," Wu said.

Soybeans can prevent cancer

Soybean meal is a bi-product following oil extraction from soybean seeds. It is rich in protein, which usually makes up around 40% of the nutritional components of the seeds and dependent on the line, and can also contain high oleic acid (a monounsaturated omega-9 fatty acid).

The study looked at the role soybeans could have in the prevention of cancer. Using a variety of soybean lines which were high in oleic acid and protein, the researchers looked to monitor bioactivity between the peptides derived from the meals of soybean and various types of human cancer cells.

The study showed that peptides derived from soybean meal significantly inhibited cell growth by 73% for colon cancer, 70% for liver cancer and 68% for lung cancer cells using human cell lines. This shows that the selected high oleic acid soybean lines could have a potential nutraceutical affect in helping to reduce the growth of several types of cancer cells.

DHA supplementation enhances high-frequency, stimulation-induced synaptic transmission in mouse hippocampus - Applied Physiology, Nutrition, and Metabolism

In continuation of my update on DHA...

A team led by Yves Sauve, who is a member of the University of Alberta's Faculty of Medicine & Dentistry, divided ten mice to receive a diet supplemented with DHA or an unsupplemented diet.  Animals that received DHA-enhanced diets were found to have a 29 percent higher level of DHA in the brain's hippocampus region—which is involved in memory--compared to the control group.  Higher DHA levels were associated with increased synaptic transmission in the hippocampus following brief stimulation.  “This increase in synaptic transmission might provide a physiological correlation for the improved spatial learning and memory observed following DHA supplementation,” the authors conclude.

"We wanted to find out how fish intake improves memory," explained Dr Sauve, who works in the University's department of physiology, the department of ophthalmology and the Centre for Neuroscience. "What we discovered is that memory cells in the hippocampus could communicate better with each other and better relay messages when DHA levels in that region of the brain were higher. This could explain why memory improves on a high-DHA diet."

He added that supplementing your diet with DHA, either by increasing fish intake or by consuming omega-3 supplements, may help protect against reduced brain DHA levels as we age.

Omega-3 supplementation improves working memory in young adults

In continuation of my update on omega fatty acid

University of Pittsburgh researchers led by Rajesh Narendran of the Department of Radiology tested the effects of a supplement providing 930 milligrams eicosapentaenoic acid (EPA) and 750 milligrams docosahexaenoic acid (DHA) in 11 men and women between the ages of 18 and 25. Evaluation of working memory (via an "n-back test"), positron emission tomography (PET) imaging of the brain and tests for red blood cell fatty acid levels were conducted before and after the six month treatment period.

Participants experienced an increase in plasma omega-3 fatty acid levels and improvement in working memory at the end of six months. "What was particularly interesting about the presupplementation n-back test was that it correlated positively with plasma omega-3,"observed Bita Moghaddam, whose lab conducted the research. "This means that the omega-3s they were getting from their diet already positively correlated with their working memory."

"Before seeing this data, I would have said it was impossible to move young healthy individuals above their cognitive best," he remarked. "We found that members of this population can enhance their working memory performance even further, despite their already being at the top of their cognitive game."

Although the researchers had suggested increases in dopamine storage and a protein involved in decision making in a particular area of the brain as mechanisms supporting omega-3's effect on cognitive function, PET scan results failed to support the hypothesis. "It is really interesting that diets enriched with omega-3 fatty acid can enhance cognition in highly functional young individuals," Dr Narendran commented. "Nevertheless, it was a bit disappointing that our imaging studies were unable to clarify the mechanisms by which it enhances working memory."

Scientists unravel action mechanism of castor oil

Scientists unravel action mechanism of castor oil: Castor oil is known primarily as an effective laxative; however, it was also used in ancient times with pregnant women to induce labour. Only now have scientists at the Max Planck Institute for Heart and Lung Research succeeded in unravelling the mysteries of the action mechanism. A receptor by the name of EP3 on the cells of the intestine and uterus is apparently responsible. This is activated by an ingredient, i.e., Ricinoleic acid (12-hydroxy-9-cis-octadecenoic acid) is an unsaturated omega-9 fatty acid in the oil, see the structure).

Scientists discover how omega-3 fatty acids shut down inflammation and reverse diabetes

(Picture, courtsey : Cell) Omega-3 fatty acids (-3 FAs), DHA and EPA, exert anti-inflammatory effects, but the mechanisms are poorly understood. Now the  researchers  show that the G protein-coupled receptor 120 (GPR120) functions as an -3 FA receptor/sensor. As per the claim by the researchers, stimulation of GPR120 with -3 FAs or a chemical agonist causes broad anti-inflammatory effects in monocytic RAW 264.7 cells and in primary intraperitoneal macrophages. All of these effects are abrogated by GPR120 knockdown. Since chronic macrophage-mediated tissue inflammation is a key mechanism for insulin resistance in obesity, researchers fed obese WT and GPR120 knockout mice a high-fat diet with or without -3 FA supplementation.

The -3 FA treatment inhibited inflammation and enhanced systemic insulin sensitivity in WT mice, but was without effect in GPR120 knockout mice. In conclusion, GPR120 is a functional -3 FA receptor/sensor and mediates potent insulin sensitizing and antidiabetic effects in vivo by repressing macrophage-induced tissue inflammation. ….....

Flaxseed-fed chickens shed light on ovarian cancer.....

In continuation of my update on the benefits of  flax seeds,  I found this info interesting to share with. Researchers from College of Agricultural, Consumer and Environmental Sciences, lead by Prof. Janice Bahr, have come up with interesting info about flax seeds, i.e., hens fed a flaxseed-enriched diet for one year experienced a significant reduction in late-stage ovarian tumors.

The interesting part of the research lies in that fact that, chicken is the only animal that spontaneously develops ovarian cancer on the surface of the ovaries like humans and researchers  evaluated how a flaxseed-enriched diet affected 2-year-old laying hens (hens that have ovulated as many times as a woman entering menopause). As we know flaxseed is the richest plant source of alpha-linolenic acid, (omega-3 fatty acid). Several studies have already shown that flaxseed inhibits the formation of colon, breast, skin and lung tumors.

As per the claim by the researchers, hens fed the control diet had significantly more late-stage tumors that presented with fluid and metastases as compared to the hens fed a flaxseed diet. Though hens fed the flaxseed diet did not have a decreased incidence of ovarian cancer, they did experience fewer late-stage tumors and higher survival rates.

In addition, researchers found that hens fed the flaxseed diet had better weight control which is important because obesity increases cancer risk. Both diets had equal caloric content, however the flaxseed-fed hens weighed less at six months than the control-fed hens. But at 12 months, the flaxseed-fed hens were the same weight and the control-fed hens had loss significant weight, which was indicative of their failing health. Ultimately, the flaxseed-enriched diet helped the birds maintain a healthy weight and resulted in less sickness and death.

"Through this research, we have proven that flaxseed supplementation for one year is able to reduce the severity of ovarian cancer in hens," she said. "These findings may provide the basis for a clinical trial that evaluates the efficacy of flaxseed as a chemosuppressant of ovarian cancer in women."

Bahr believes this hypothesis is valid and is currently in the middle of a four-year study to determine if long-term dietary intervention with flaxseed will reduce the incidence of ovarian cancer development....

The Secret of Lowering Cholesterol Through Diet...

I am really happy to share an interesting and important article  'the secret of lowering cholesterol through diet' by  Deborah Land, who has written this article exclusively for the readers of  my blog.......

The Secret of Lowering Cholesterol Through Diet

a. The Myth of Cholesterol - the Bad and the Good:

Most people think that cholesterol is always bad, but there are actually two types of cholesterol. LDL is  considered the "bad" cholesterol, and HDL is considered the "good" cholesterol. If there is too much LDL in our bloodstream, it will form plaque on our arteries. Over time, this narrows our arteries and can eventually block blood flow completely. Dietary cholesterol actually isn't the primary reason for high cholesterol in the blood; it is high amounts of saturated fat and trans fat. To keep cholesterol low, you should eat unsaturated fats, eat fibrous foods, and exercise more.

b. Number Relevance in Cholesterol :
Every adult should have their cholesterol checked at least every 5 years. When you get a cholesterol test, you'll usually get back four different results. Here are the 4 categories and the healthy range you want to be in.

Total Cholesterol - less than 200 mg/dL (5.2 mmol/L);
LDL Cholesterol - less than 100 mg/dL (2.6 mmol/L);
HDL Cholesterol - greater than 40 mg/dL (1.0 mmol/L) &
Triglycerides - less than 150 mg/dL (1.7 mmol/L).

If you are over or under the desired level on any category, it is usually indicative that a diet or exercise change is needed.

c. Heart Protection and Vitamin E:
Vitamin E, an important vitamin, is sourced in vegetable oils, nuts and leafy vegetables. Vitamin E can decrease your heart disease risk, but it will not prevent a heart attack.

d. Lowering Cholesterol with these Five Foods :
1. Oatmeal and Oat Bran: These contain a high amount of soluble fiber, which can lower LDL.
2. Fish: Fish is a great source of omega 3 fatty acids, which lowers LDL and raises HDL.
3. Nuts: Not only are nuts high in fiber, but they contain the healthy fats you need to keep LDL in check.
4. Plant Sterols: This is found in foods like margarine, salad dressing, orange juice, and functional cookies. 2  grams per day will lower your LDL by 10-15%.
5. Soy: This popular meat replacement can lower LDL by up to 3%.

e. Plant Sterols and Benefits to Health :
Foods such as VitaTops Muffin Tops, Benecol Spread, granola bars and fat free milk are rich sources of plant sterols. You can easily help your heart when you start eating foods packed with plant sterols and avoid eating foods that contain saturated fats. A saturated fat-filled diet is not canceled out by this. Exercising often as well as eating healthy food will keep your cholesterol in check.

Flaxseed lowers high cholesterol in men.....

Flax (also known as common flax or linseed) (Linum  usitatissimum) is a member of the genus Linum in the family Linaceae. It is native to the region extending from the eastern Mediterranean to India.  This is called as Agasi/Akshi in Kannada, Jawas/Javas (जवस) or Alashi (अळशी) in Marathi.  

Flax seeds come in two basic varieties brown yellow or golden. Most types have similar nutritional characteristics and equal amounts of short-chain omega-3 fatty acids. The exception is a type of yellow flax called Linola or solin, which has a completely different oil profile and is very low in omega-3. Although brown flax can be consumed as readily as yellow, and has been for thousands of years, it is better known as an ingredient in paints, fiber and cattle feed. Flax seeds produce a vegetable oil known as flaxseed or linseed oil, which is one of the oldest commercial oils and solvent-processed flax seed oil has been used for centuries as a drying oil in painting and varnishing. 

Flaxseeds are rich in alpha linolenic acid (ALA), an omega-3 fat that is a precursor to the form of omega-3 found in fish oils called eicosapentaenoic acid or EPA. Many benefits like 1. anti-iflammatory benefits, 2. omega-3-rich flaxseeds protect bone health, 3.protection against heart disease, cancer and diabetes, 4. flaxseeds help prevent and control high blood pressure. And even it helps to control some types of cancers.

Earlier report says,  Flaxseed provides comparable cholesterol-lowering benefits to statin drugs. Now this has been further substantiated by researchers from Iowa State University's (ISU) Nutrition and Wellness Research Center (NWRC).

Suzanne Hendrich, an ISU professor in food science and human nutrition, led a study that examined the effects of flaxseed lignan in 90 people diagnosed with high cholesterol. The results showed that consuming at least 150 milligrams of flaxseed lignans per day (about three tablespoons) decreased cholesterol in men, but not women, by just under 10 percent over the three months that they were given the flaxseed.  Suzanne concludes that though the result is  considerably less than the expected outcome from cholesterol-lowering drugs -- approximately 10 to20 percent for three months, depending on the individual -- it's still enough to make flaxseed a more natural option for some men. While the study found that the flaxseed lignans lowered cholesterol in men, it did not produce a significant change in women. More....

Omega-3 Fatty Acids for protecting the liver from damage caused by obesity and the insulin resistance it provoke...

(1)--alpha-linolenic acid (ALA),


(2)-eicosapentaenoic acid (EPA)





(3)-docosahexaenoic acid (DHA)

According to a recent study by Dr. Joan Claria and co workers, diets rich in omega-3 fatty acids (1, 2 & 3) protect the liver from damage caused by obesity and the insulin resistance it provokes. This research should give doctors and nutritionists valuable information when recommending and formulating weight-loss diets and help explain why some obese patients are more likely to suffer some complications associated with obesity. Omega-3 fatty acids can be found in canola oil and fish.

The researchers found that lipids called protectins and resolvins derived from omega-3 fatty acids can actually reduce the instance of liver complications, such as hepatic steatosis and insulin resistance, in obese people. The group claims that, two types of lipids in omega-3 fatty acids—protectins and resolvins—were the cause of the protective effect. These results are based on animal models of testing and hope this info will help dieticin to prepare list of diets to reduce the obesity, with reduced complications to the liver. More....
