Veggies, Fruits and Grains Keep Your Heart Pumping

Conversely, the so-called Southern diet, which focuses on meats, fried and processed foods and lots of sweet tea, was tied to a 72% increased risk of heart failure.

"Eat more plants, limit red and processed meat," said lead researcher Dr. Kyla Lara, a cardiology fellow at the Mayo Clinic in Rochester, Minn.

Lara cautioned that this study cannot prove different diets cause or prevent heart failure, only that they are linked.

Nearly 6 million American adults suffer from heart failure, and that number is expected to rise with the aging population. The condition occurs when the heart does not pump blood sufficiently to meet the body's needs.

Steps to prevent heart failure include not smoking, keeping blood pressure under control, maintaining a healthy weight and eating healthy foods.

Getting people to eat healthier requires that they be educated about the benefits of plant-based diets and have access to low-cost healthy foods, Lara said.

"Animal meat is not necessary for a nutritious diet, in terms of health promotion and quality of life," she said. "Now is the time to get on board with a plant-based diet -- it's going to be the future of health."

In the study, Lara and her colleagues collected data on more than 16,000 men and women, 45 and older, who took part in a large U.S. stroke study. None of the participants had heart disease at the start of the study. Participants completed a questionnaire that asked them about their diet.

The diets were classified into five types:

Convenience, which was heavy on meats, pasta, Mexican food, pizza and fast food.

Plant-based, which included vegetables, fruits, beans and fish.

Sweets and fats, which was heavy on desserts, bread, sweet breakfast foods, chocolate and other sugars.

Southern, which was heavy on fried foods, processed meats, eggs, added fats, and sugar-sweetened drinks.

Alcohol and salads, which was heavy on wine, liquor, beer, leafy greens and salad dressing.

After nearly nine years of follow-up, 363 participants developed heart failure.

The benefit of the plant-based diet was significant, but after taking into account factors such as weight, waist size, high blood pressure and high cholesterol, the negative effect of the Southern diet was no longer statistically significant, Lara said.

It might be that the increased risk for heart failure in this group was due to obesity and excess belly fat or other factors, she said.

None of the other diets showed a statistically significant association with heart failure, and no association was seen between any diet and the type of heart failure people developed, the researchers noted.

The findings were published April 22 in the Journal of the American College of Cardiology.

"Our lifestyle, such as what we eat, if we are physically active and smoking or vaping, can contribute significantly to a poorly functioning heart, which in turn affects our quality of life and ultimately how soon we die," said Samantha Heller, a senior clinical nutritionist at New York University Medical Center in New York City.

Plant-based diets have been shown to reduce the risk of cardiovascular disease, cognitive [thinking] decline, type 2 diabetes, several cancers, depression and obesity," said Heller, who wasn't involved with the study.

For optimal health, people need to cut back on fried foods, cheese, fast food and junk foods, and processed and red meats, she said.

"It is sad and frustrating when I see patients who could quite literally save their lives by making healthier choices, but instead opt for a burger and fries," Heller said.

A cheeseburger, fries and milkshake meal sounds innocent enough, but it can add up to more than 2,600 calories, 65 grams of saturated fat and 3,400 milligrams of salt, she said.

Heller advises people to include a minimum of one high-fiber food to every meal. "Dietary fiber is only found in plant foods, such as spinach, oranges, quinoa and lentils."

Also try having meatless dinners two or three nights a week, like a grilled vegetable and black bean burrito, pasta primavera or an edamame and fresh vegetable stir fry, she suggested.failure by 41%.

Fruits, Veggies Powerful Rx for Kidney Disease: Study

Kidney disease patients who eat three to four more servings of fruits and vegetables every day could lower their blood pressure and nearly halve their medication costs, new research suggests.

The findings stem from the multi-year tracking of a small group of patients, in which standard medical treatment was compared with the simple nutritional intervention.

The goal: to see which approach did a better job at driving down both blood pressure and drug expenses.

The result on both fronts showed a clear win for healthy food.

Study author Dr. Nimrit Goraya described the links seen between increased fruit and vegetable intake, kidney disease control and lower medication expenses as "huge." And "the impact was visible from the very first year," she said.

"This study has been done over five years, but every year since the therapy with fruits and vegetables began, we were able to lower medications," she noted.

Goraya is program director for nephrology with Baylor Scott & White Healthcare in Temple, Texas.

She and her colleagues are scheduled to present their findings this week at an American Heart Association meeting on blood pressure, in Orlando, Fla.

High blood pressure is the second leading cause of kidney failure. The kidneys and the circulatory system depend on each other for good health, according to the heart association.

In all, 108 kidney disease patients were enlisted in the study, all of whom were taking similar doses of blood pressure drugs.

Patients were divided into three groups. One group was treated with sodium bicarbonate (baking soda), the standard treatment designed to neutralize the lingering acid that kidney patients typically struggle to excrete. Failure to excrete can lead to abnormally high acid levels, a condition known as "metabolic acidosis."

A second group was not prescribed sodium bicarbonate, but instead was provided three to four servings of fruits and vegetables a day. These patients were not instructed to alter their usual diet beyond consuming their new fruit and vegetable allotment.

A third group was not treated in any way.

The result: After five years, systolic blood pressure (the top number in a reading) was pegged at 125 mm Hg among the fruit and vegetable group, compared with 135 mm Hg and 134 mm Hg, respectively, among the medication and no treatment groups.

What's more, those in the food group were taking considerably lower doses of daily blood pressure medication than those in the other groups, the study authors said.

This translated into a near halving of the food group's total expenditure on such drugs, down to roughly $80,000 over five years compared with an average total of more than $153,000 among each of the other two groups.

As to the exact mechanisms by which an increased intake of fruits and vegetables appears to promote kidney disease control, Goraya pointed to a variety of things that are set in motion whenever nutrition improves.

"I think that the benefit is not singular," she said. Goraya suggested that kidney disease control is likely triggered not only by the protective benefits of healthier foods but also by a corresponding reduction in fast-food consumption, a lowering of salt intake, and perhaps even weight loss.

Those looking for more ways to achieve some measure of kidney disease control without medication might look to the findings of a new Brazilian study also presented at the Orlando meeting that highlighted the potential benefits of exercise.

After reviewing 28 studies involving more than 1,000 patients on dialysis, researchers at the University of Sao Paulo Medical School found that those who routinely engaged in both aerobic exercise and resistance (strength) training significantly lowered their blood pressure.

Lona Sandon is program director in the department of clinical nutrition at the School of Health Professions at UT Southwestern, in Dallas. "It is remarkable what fruits and vegetables can do, along with a little exercise," she said.

"Blood pressure meds come with many side effects that may leave people feeling sluggish, or other problems," Sandon explained. "The side effects of fruits and vegetables and exercise is better health."

The bottom line: "When people have access to healthy foods, they can change their health," said Sandon. "And especially when they eat the recommended amounts that were provided to them in the study."

The findings of studies presented at medical meetings should be viewed as preliminary until published in a peer-reviewed journal.

High fruit intake during adolescence linked with lower breast cancer risk: But increasing alcohol intake in later life associated with higher risk

The first study reports that high fruit consumption during adolescence may be associated with lower breast cancer risk, while the second study finds that increasing alcohol intake in later life is associated with an increased risk of breast cancer.

Fruit and vegetables are thought to protect against breast cancer, but the evidence is conflicting. Most studies have assessed intakes during midlife and later, which may be after the period when breast tissue is most vulnerable to carcinogenic influences.

So a team of US researchers wanted to see whether fruit and vegetable consumption might affect subsequent breast cancer risk. They followed 90,000 nurses for over 20 years who reported their diet in early adulthood, of whom half also recalled their usual diet during adolescence.

They found that high fruit consumption during adolescence (2.9 v 0.5 servings per day) was associated with a roughly 25% lower risk of breast cancer diagnosed in middle age.

In particular, greater consumption of apple, banana and grapes during adolescence, as well as oranges and kale during early adulthood was significantly associated with a reduced breast cancer risk. But there was no link between intake of fruit juice in either adolescence or early adulthood and risk.

The authors say their findings are in line with cancer prevention advice to eat more fruits and vegetables, and suggest that food choices during adolescence may be particularly important.

In a linked editorial, University of Oxford researchers say "much more evidence is needed before we can draw conclusions on the reported protective association between adolescent fruit intake and breast cancer risk." But that these foods "have well known beneficial effects on health, and efforts should continue to increase intake of both fruit and vegetables at all ages."

In the second study, a team of Danish researchers wanted to test the effect of a change in alcohol intake on the risk of breast cancer and heart disease. Alcohol is responsible for about 11% of female breast cancers in the UK.

They followed the health of nearly 22,000 post-menopausal women in Denmark and found that women who increased their alcohol intake by two drinks per day over five years had around a 30% increased risk of breast cancer but around a 20% decreased risk of coronary heart disease, compared with women with a stable alcohol intake.

However, results for women who decreased their alcohol intake over the five year period were not significantly associated with risk of breast cancer or coronary heart disease.

Altogether, the authors say their findings support the hypothesis that alcohol is associated with breast cancer and coronary heart disease in opposite directions.

The results for breast cancer are in line with previous research, but the true effect of alcohol on risk of ischaemic heart disease remains uncertain, say the editorial authors.

"There may be some benefit with low to moderate intakes of alcohol, but this could be outweighed by an increased risk of breast cancer and other morbidities," they explain. "Furthermore, risk of ischaemic heart disease can be reduced substantially by other lifestyle changes, as well as by drugs such as statins shown to be effective in primary prevention."

Both studies are observational, so their interpretation needs to consider the potential impact of other factors before any firm conclusions can be drawn about cause and effect, they add.

Eating fruits, vegetables linked to healthier arteries later in life

Women who reported consuming the most fruits and vegetables (eight to nine servings a day for a 2,000-calorie diet) in their 20s were 40 percent less likely to have calcified plaque in their arteries in their 40s compared with those who ate the least amount (three to four servings a day) during the same time period. This association persisted even after researchers accounted for other lifestyle behaviors, as well as for their current-day diets, further demonstrating the role dietary patterns at younger ages may play. 

"These findings confirm the concept that plaque development is a lifelong process, and that process can be slowed down with a healthy diet at a young age," Miedema said. "This is often when dietary habits are established, so there is value in knowing how the choices we make in early life have lifelong benefits."

Surprisingly, the same benefit did not hold true for men, which warrants further investigation.

"Several other studies have also suggested that a diet high in fruits and vegetables is less protective in men, but we do not have a good biological reason for this lack of association," Miedema said, adding that the study had less power to evaluate men (62.7 percent were female vs. 37.3 percent male).

The study included 2,508 participants from the ongoing government-sponsored Coronary Artery Risk Development in Young Adults (CARDIA) study, which is evaluating how heart disease develops throughout adulthood. CARDIA began in the mid-1980s with a group of men and women 18-30 years of age and has collected extensive data on medical, socioeconomic, psychosocial and behavioral characteristics.

Fruits better than prviously thought !.......

Polyphenol content in fruits usually refers to extractable polyphenols, but a Spanish scientist working at the Institute of Food Research in Norwich analysed apple, peach and nectarine. She found that nonextractable polyphenol content is up to five times higher than extractable compounds. Its really interesting and that might be the reason why our forefathers used to insist to eat whole fruits (though they might not have studied so exhaustively... !).  

The interesting findings like,  "polyphenols need to be treated with acid to extract them from the cell walls of fruit in the lab" will help at least now onwards to collect all the useful polyphenols (proanthocyanidins, ellagic acid and catechin)  which without this new findings might have gone as waste.  Dr Paul Kroon from IFR explains: “In the human body these compounds will be fermented by bacteria in the colon, creating metabolites that may be beneficial, for example with antioxidant activity. 

Hope these  nonextractable polyphenols, (which mostly escape analysis and are not usually considered in nutritional studies),  will play a major part of bioactive compounds in the diet  in the days to come. Congrats Professor Saura-Calixto, for this  achievement.....
