First Middle East study finds significant association between glycaemic index and breast cancer

Published

on

The Middle East is a large consumer of refined carbohydrates, so this study aimed to examine the relationship between GI, GL, Carbohydrate Quality Index (CQI) and the likelihood of breast cancer in women in a case-control study.

“To the best of our knowledge, there has not been a large sample study in the Middle East in this regard. Due to the different nutritional patterns in the Middle East, research in this region is necessary to find out this connection, ”researchers from the Tehran University of Medical Sciences write in the Nutrition Journal.

Study design

Iranian women aged 19 to 80 participated in this study between 2014 and 2016. A total of 461 women with breast cancer diagnosed the previous year and 495 women without breast cancer were included.

A validated food frequency questionnaire was used to assess previous year food intake.

From the data, the researchers were able to calculate GI, GL and the carbohydrate quality index. Carbohydrate quality was determined as the ratio of solid carbohydrates to total carbohydrates, fiber intake, GI, and the ratio of whole grains to total grains.

The mean GI and GL of the participants were 57.5 ± 7.2 and 245.7 ± 64.7, respectively.

GI is directly connected

The results showed that people in the top quartile of the GI were 1.41 times more likely to develop breast cancer than those in the bottom quartile for the entire population. In premenopausal women, women in the top quartile of the GI were 1.85 times more likely to develop breast cancer than women in the bottom quartile.

“The proposed mechanism is high insulinemia resulting in a high glycemic diet that can inhibit apoptosis and synthesis of IGF-binding proteins, which promotes cell proliferation,” the researchers explained.

However, no significant association between GL and breast cancer risk was observed in the entire population.

For the Carbohydrate Quality Index (CQI), women in the highest quartile of the CQI had a significantly lower risk of breast cancer than those in the lowest quartile, among all participants and those in the premenopausal stage.

“We found no significant association between carbohydrate quality and breast cancer risk in postmenopausal women.”

Recent discussions suggest that fiber and whole grains should be considered for carbohydrate quality.

“A high-fiber diet offers many health benefits, including weight loss, lowering cholesterol, and reducing insulin resistance. In addition, fiber can lower circulating estrogen levels by altering the gut microbiota, which affects the reactivation of conjugated estrogens. “

“Therefore, the CQI, which takes into account fiber, GI, solid or liquid form of carbohydrates, and whole grains or refined grains, seems to be a better index for the rating.”

One of the explanations for the CQI’s role in reducing cancer risk is its anti-inflammatory properties.

“Whole grains are rich in antioxidants, which are important elements of antioxidant enzyme activity and, conversely, have been linked to breast cancer risk. Whole grain products therefore have phytoestrogens and polyphenols, which have antioxidant properties and the potential to inhibit cell reproduction and angiogenesis and to cause cell apoptosis. “

The researchers added, “To the best of our knowledge, this case-control study is among the first to report the association between total carbohydrates, GI, GL and CQI and the likelihood of large-sample breast cancer in a Middle Eastern country.”

“So when you consider that carbohydrate intake could be important for fighting cancer in society.”

One of the limitations of this study was its case-control design, which cannot infer causality. Prospective cohort studies are needed to investigate the relationship between carbohydrate quality and breast cancer risk, especially between pre- and postmenopausal women.

Protein Variety and Heart Health Are Linked, Study Finds

Published

on

We’ve all found ourselves in the habit of eating the same three things over and over (…and over) again. When life gets busy, falling back on simple dishes that satisfy your tastebuds is the natural thing to do. But if you’re cooking up the same couple proteins on the regular, a new study published in the the journal Hypertension suggests that it may be time to introduce a few new varieties into your breakfasts, lunches, and dinners.

The study pulled existing data from over 12,000 participants who took part in a minimum of two rounds of the China Health and Nutrition Survey. Researchers sought to explore the relationship between hypertension—or high blood pressure—and the variety and quantity of proteins from eight major dietary sources consumed by participants. (Study participants were an average age of 41 years old.)

Researchers measured protein intake by looking at three consecutive days of eating, scoring each round based on the number of protein varieties consumed (including legumes, fish, eggs, whole grains, refined grains, processed and unprocessed red meat, and poultry).

The results? “Among ‘just the right amount’ consumers of protein, those eating the greatest variety of protein had a the lowest blood pressure,” explains John Higgins, MD, a sports cardiologist with McGovern Medical School at the UT Health Science Center at Houston. Notably, those who ate the least and the most amount of protein were at the greatest risk for developing high blood pressure, while those who ate the greatest variety of protein were 66 percent less likely to end up developing hypertension between the rounds of the survey .

“The heart health message is that consuming a balanced diet with proteins from various different sources, rather than focusing on a single source of dietary protein, may help to prevent the development of high blood pressure.” — Xianhui Qin, MD, study author

Although the survey results sound complicated—and, hey, they were—the takeaway is simple: “The heart health message is that consuming a balanced diet with proteins from various different sources, rather than focusing on a single source of dietary protein, may help to prevent the development of high blood pressure,” Xianhui Qin, MD, the study author, said in a press release. In other words: Mix it up! Spin the protein wheel of fortune and try something new.

Related Stories

If you’re not quite sure where to start with upping your protein game, Dr. Higgins recommends looking at your consumption on a daily basis. “The American Heart Association recommends eating no more than about 5.5 ounces of protein daily, about one to two servings, from healthy sources such as plants, seafood, low-fat or fat-free dairy products and some lean meats and poultry,” he says. “The best proteins are lean proteins including beans, soy or tofu, fish, skinless chicken, very lean meat, and low-fat dairy products. Avoid proteins that say ‘hydrogenated’ on label or contain high levels of trans fats or saturated fats. “

Of course, there’s always room in your eating plan for less nutritional proteins, too—just try to incorporate these lean sources when you can, and ask your doctor if you have questions about what dietary habits are right for your particular health status and family history .

    How to Choose a Diet Book

    If you’re looking to switch up your diet, the first thing you should ask yourself is why. What exactly do you want out of a diet?

    Second, consider your lifestyle. Do you need meals that are quick and easy? Do you like to take an hour or two to cook for yourself every night? How often can you grocery shop for fresh ingredients?

    Finally, consider whether you’re looking specifically for a cookbook or one that will provide you education on a particular way of eating without necessarily giving you recipes. While many cookbooks will have some content that discusses the origins of food and their nutritional benefits, these books are unlikely to go as in-depth regarding nutrition as less recipe-focused ones.

    How We Selected

    To find the best diet books among the many options on the market, we researched the most popular books available and considered their content, credibility, design, digestibility, and organization. We then looked at both expert reviews and more than 105,000 customer ratings, written by people who’ve bought these books on Amazon, to settle on the diet books you’ll find below.

Eating different kinds of protein protects against hypertension: New study

Published

on

Despite all this talk that more Australians are toying with vegetarianism, and despite the endless drum-beating about red meat giving you cancer and a dodgy heart, we continue to have one of the world’s highest levels of meat consumption.

Analysis published in December found Australians eat about 95 kilograms of meat per capita every year. The global average is 35 kilograms.

The article, ‘The Evolution of Urban Australian Meat-Eating Practices’, argues our meat-eating habits are driven by a blocky culture, an association with social status, a perception that plant-based diets are inadequate and lame, and ignorance about cooking legumes and tofu.

On the other hand, the authors point to a survey that found almost 20 per cent of those sampled “identified as meat-reducers”.

Furthermore, the authors say, 87 percent “of the meat reducer segment reported consuming a meat-free dish as their main meal at least once a week”.

They point to another survey that found almost 20 per cent described themselves as “flexitarian”, which is cool.

But it may not translate to more lentils, nuts, whole grains, fish and dairy hitting the dinner table as new favorite sources of protein.

A new study found why we need variety

Chinese researchers found that “eating protein from a greater variety of sources is associated with a lower risk of developing high blood pressure”.

Good to know because blood pressure is literally out of control in Australia.

One in three adults – more than six million Australians – has high blood pressure.

Of those afflicted, only 32 per cent have their hypertension under control. That leaves about four million Australians as ticking time bombs.

In December, in the Medical Journal of Australia, Professor Alta Schutte, Professor of Cardiovascular Medicine at UNSW Sydney, called for a national taskforce to tackle the issue.

By improving the control of hypertension, the risks of coronary heart disease, dementia and cerebrovascular disease will be substantially reduced.

The Chinese study suggests changing your diet will go some way to solving the problem.

the study

“Nutrition may be an easily accessible and effective measure to fight against hypertension. Along with fat and carbohydrates, protein is one of the three basic macronutrients,” said study author Dr Xianhui Qin, of the National Clinical Research Center for Kidney Disease at Nanfang Hospital, Southern Medical University in Guangzhou, China.

The study authors analyzed health information for nearly 12,200 adults (average age 41), who had taken part in multiple rounds of the China Health and Nutrition Survey from 1997 to 2015.

Over three days in the same week, participants shared what they had eaten.

They were given a protein “variety score” based on the different sources of protein they’d eaten: whole grains, refined grains, processed red meat, unprocessed red meat, poultry, fish, egg and legumes.

One point was given for each source of protein, with a maximum variety score of 8. The researchers then evaluated the association for new onset hypertension in relation to the protein variety score.

New-onset hypertension was defined as blood pressure greater than or equal to 140 mm Hg/90 mm Hg, the use of blood pressure-lowering medicine, or self-reporting that a physician had diagnosed high blood pressure.

The average follow-up time was six years.

The results

More than 35 per cent of the participants developed new-onset high hypertension during the follow-up.

Compared to participants with the lowest variety score for protein intake (1), those with the highest variety score (4 or higher) had a 66 per cent lower risk of developing high blood pressure.

The amount of protein eaten was also a factor. Consumption was divided into five categories, from least to most intake.

The researchers found that “people who ate the least amount of total protein and those who ate most protein had the highest risk for new onset of hypertension”.

The researchers didn’t ask why a variety of proteins was more healthy. But nutritionists, doctors and health writers have banged on about it for years.

Lean red meat is high in quality protein but provides no fiber or healthy fats. Processed meats are high in saturated fats and salt and are the worst.

Fish is high in long-chain fatty acids, which are good for the brain. Lentils and whole grains are high in fibre.

Hand on heart, a bit of each during the week might stop you from carking it in the street. Which is just undignified and unmanly.
