Warning: Eat ultra-processed foods only in moderation~~~

Eating Ultraprocessed Foods Increases Risk of Cancer

450, 111 adults in the European Propective Invesigation were recruited from 1992 to 1999 from 10 different European countries and the United Kingdom.

Results showed that people who consumed just 10% more ultra-processed foods than others in the study had a:

23% higher risk of head and neck cancers and a 24% increased risk of esophageal cancer.

Ultra processed foods include sodas, instant soups, cookies, ice cream, cereal bars and other foods that make up about 71% of the food supply in the U.S. A rule: If it comes in a box or package (ready-made), it is most likely to be an example of an ultraprocessed food. Some are for convenience; use them in moderation.

Other studies have shown that:

Men who consume ultraprocessed foods have a higher risk of colorectal cancer, heart disease and early death.

For every 10% increase in ultraprocessed food, there is a 2% increase in developing any kind of cancer and a 19% increased risk of ovarian cancer.
Consuming more ultra-processed foods is connected to depression in women.
Consuming about 20% of daily calories in ultra processed foods is linked to 28% increased risk of dementia.

What Could Go Wrong?

Concept Check: How DID We Get this OLD?

Although life span has not changed, life expectancy has increased dramatically over the past century,

With rare exceptions, life expectancy has been on the rise in the U.S. It was 47 years in 1900, 68 years in 1950, and by 2019 it had risen to nearly 79 years. But it fell to 77 in 2020 and dropped further to just over 76 in 2021. (can you think Covid?) Harvard Health.

The causes of aging are still a mystery.Most likely, aging results from an interaction of genetic and the changes listed in the table below: The science of epigenetics also can offer lifestyle factors to further influence the changes that normally occur with “normal aging”.

Aging occurs due when:
Errors occur in copying the genetic blueprint (DNA)
Connective tissue stiffens. Parallel muscle proteins cross link.
Electron – seeking compounds (free radicals) damage cell.
Hormone functions change.
Blood glucose attaches to various blood and body proteins. Occurs in poorly controllled diabetes
The immune system loses some efficiency and fails to recognize foreign substances.
Autoimmunity develops. Immune function cells destroy “self”.
Death is programmed into the cell, e.g. each cell can only divide about 50 times; after that the cell dies and succumbs.
Excess energy intake speeds body breakdown and may even cause premature death. In research, underfed animals live longer by calorie restriction. Diet can slow down some of these processes?

WOW!!! What else could go wrong?

U.S. Diets: (Sally J. Feltner)

Assessing the latest U.S. dietary guidelines: Will they be able to make a difference? Sally J. Feltner, MS.,Ph.D

January 20, 2021—Eric Rimm, professor in the Departments of Epidemiology and Nutrition at Harvard T.H. Chan School of Public Health, discussed the recently released 2020–2025 U.S. Dietary Guidelines. Rimm served on the Scientific Advisory Committee in 2010.

What’s your assessment of the new guidelines?

This is the first time that the guidelines include advice for children under two. They now actually address healthy eating across the lifespan. I think this is an important change because of the likely role that early diet plays in laying the foundation for healthy dietary habits and a lifetime of disease prevention. The government made a conscious effort to include more pediatricians on the advisory committee, including Elsie Tavares, who has an appointment in our Department of Nutrition. These guidelines will be used to inform government nutrition policy, so I think that was a good step forward.

What was disappointing to me was that the government decided to take a pass on changing recommendations for daily calories from added sugar. The scientific advisory committee had recommended lowering limits from 10% to 6%, but the official government guidelines kept the recommendation at the upper level.

However, I agreed with the decision to leave out the committee’s recommendation to lower alcohol guidelines for men from a maximum of two daily drinks to one. I was the alcohol expert in 2010, and I believe the science still supports what was in the previous guidelines in 2010 and 2015, that is, up to two drinks a day for men and one for women. I think it is important that if a government body is going to make a substantial change in policy statement about alcohol that it be as scientifically accurate as possible.

Going forward, we need to focus on understanding and promoting healthy drinking patterns. The guidelines are very clear on up to two drinks for men in any given day—not seven on Friday and seven on Saturday. With people drinking a lot more at home during the pandemic, it may be a good time to remind people that binge drinking is harmful.

How can the average person make sense of the guidelines and apply some of the recommendations in their own diets?

The guidelines are primarily aimed at policy makers and academics, so people may find some of the recommendations difficult to translate to their lives. Take counting calories, for example. If you give most people a plate of food and ask them how many calories it contains, they won’t know. I don’t blame them. It’s a really hard thing to think about when you’re making a meal.

I think a perhaps more helpful thing to focus on is eating whole foods instead of processed foods. We know that it’s better for you to eat food in its natural form. Highly processed grains like white bread, for example, strip all the good stuff out. Another important step is to choose healthier proteins—chicken and fish over red meat, or soy proteins over animal proteins.

Much of the guidelines do discuss healthy dietary patterns including the Mediterranean Diet or vegetarian diet. To help make them affordable, you can buy inexpensive proteins like dried beans, and also incorporate frozen fruits and vegetables into your diet.

What nutrition policy changes do you hope to see in the next few years?

In 2015, the advisory committee recommended incorporating sustainability into the dietary guidelines—for example, encouraging a more plant-based diet to lower the production of greenhouse gases. This was not included in the government’s official 2015 guidelines, and it did not improve in 2020. The 2020 guidelines were set up by the Departments of Agriculture and Health and Human Services with very specific parameters around what topics the scientists on the Advisory Committee could address, and sustainability was not listed. Recently, the EAT-Lancet report has really become the source for thinking about sustainability in the way we eat, but I think these conversations still have a place in the guidelines. I’m optimistic that they will eventually be included.

I’m also hopeful that standards around school meals set during the Obama administration, such as lowering amounts of saturated fat and sodium, will be restored. We’re essentially training kids’ palates for unhealthy food for life, which is so disheartening, especially since we know it’s possible to serve healthy school meals that kids will actually eat and enjoy.

Another important area is the federal Supplemental Nutrition Assistance Program (SNAP). Food insecure people in the program should be free to purchase what they want, but I think we are setting them up to fail. We need to provide incentives to help people on SNAP buy healthier food. There is robust evidence to show that if you do this, it works.

FULL STORY
A healthier diet is associated with a reduced dementia risk and slower pace of aging, according to a new study at Columbia University Mailman School of Public Health and The Robert Butler Columbia Aging Center. The findings show that a diet-dementia association was at least partially facilitated by multi-system processes of aging. While literature had suggested that people who followed a healthy diet experienced a slowdown in the processes of biological aging and were less likely to develop dementia, until now the biological mechanism of this protection was not well understood. The findings are published in the Annals of Neurology.
“Much attention to nutrition in dementia research focuses on the way specific nutrients affect the brain” said Daniel Belsky, PhD, associate professor of Epidemiology at Columbia School of Public Health and the Columbia Aging Center, and a senior author of the study.
“We tested the hypothesis that a healthy diet protects against dementia by slowing down the body’s overall pace of biological aging.”
The researchers used data from the second generation of the Framingham Heart Study, the Offspring Cohort.
Originating in 1971, participants in the latter were 60 years of age or older, were free of dementia, and also had available dietary, epigenetic, and follow-up data.
The Offspring Cohort were followed-up at nine examinations, approximately every 4 to 7 years.
At each follow-up visit, data collection included a physical examination, lifestyle-related questionnaires, blood sampling, and, starting in 1991, neurocognitive testing.
Of 1,644 participants included in the analyses, 140 of the participants developed dementia.
To measure the pace of aging, the researchers used an epigenetic clock called DunedinPACE developed by Belsky and colleagues at Duke University and the University of Otago.
The clock measures how fast a person’s body is deteriorating as they grow older, “like a speedometer for the biological processes of aging,” explained Belsky.
“We have some strong evidence that a healthy diet can protect against dementia,” said Yian Gu, PhD, associate professor of Neurological Sciences at Columbia University Irving Medical Center and the other senior author of the study, “But the mechanism of this protection is not well understood.” Past research linked both diet and dementia risk to an accelerated pace of biological aging
“Testing the hypothesis that multi-system biological aging is a mechanism of underlying diet-dementia associations was the logical next step,” explained Belsky.
The research determined that higher adherence to the Mediterranean-Dash Intervention for Neurodegenerative Delay diet (MIND) slowed the pace of aging as measured by DunedinPACE and reduced risks for dementia and mortality.
Furthermore, slower DunedinPACE accounted for 27 percent of the diet-dementia association and 57 percent of the diet-mortality association.

“Our findings suggest that slower pace of aging mediates part of the relationship of healthy diet with reduced dementia risk, and therefore, monitoring pace of aging may inform dementia prevention,” said first author Aline Thomas, PhD, a Postdoc at the Columbia Department of Neurology and Taub Institute for Research on Alzheimer’s Disease and the Aging Brain.
“However, a portion of the diet-dementia association remains unexplained, therefore we believe that continued investigation of brain-specific mechanisms in well-designed mediation studies is warranted.”
“We suggest that additional observational studies be conducted to investigate direct associations of nutrients with brain aging, and if our observations are also confirmed in more diverse populations, monitoring biological aging, may indeed, inform dementia prevention,” noted Belsky.

GIFTS FROM THE SEA

GIFTS FROM THE SEA

SOURCES: Nutrition Now, Judith E. Brown, 7th Edition

Mary B. Grosvenor, Nutrition: Science and Applications, 2013.

On one hand, salt is a gift from the sea; on the other hand, it is a hazard to health when consumed in excess. Most of the salt consumed is joined with chloriide and travels around as sodium chloride or table salt.

Every 40 seconds someone in the U.S. suffers a stroke. Fortunately, about 80% are thought to be preventable. The average American eats about 8500 milligrams of salt, double the recommended amounts, almost none of which comes from the salt shaker. It comes from processed food, an industry that hauls in $ trillions in annual sales. Your brain and your heart are the organs most affected which occurs when oxygen and and nutrients cannot get to the brain. “Hypertension can then damage the blood vessesls and cholesterol and can cause a buildup of fatty deposits that narrows arteries”.
says cardiologist Phillip Ades, M.D., Eating Well Advisor.

The Role of the Sodium/Potassium Ratio

Sodium closely works with potassium and the two help to maintain water balance in the body. They both attract water nornally and each draws sufficinent water to the outside or inside of cells to maintain an optimal level of water in both places, Water balance and cell function are upset when there’s an imbalance in the body’s supply of sodium and potassium. High dietary intakes of sodium appear to play an important role in the development of hypertension (high blood pressure) in many people.

Risk Factors for Hypertension
Obesity is a major risk factor for hypertension and the most effective treatment is weight loss. Others are age, family history, high sodium/low potassium diet, excessive alcohol intake (>two glasses /day), smoking, frequent stress, and anxiety.

Restricting highly processed foods is very effective to improve your potassium intake. High salt processed meals, salad dressings, canned soups, ham, sausages and biscuits are often the culprits. Reading food labels are also an excellent way to beware of your high sodium inake.

If blood pressure remains elevated and lifestyle changes have been inplemented, or if blood pressure is quite high when diagnosed, anti-hypertensive drugs are usually prescribed. SEE YOUR DOCTOR OR LICENSED NUTRITIONIST.
Is Sea Salt a Better Choice Than Table Salt?

A survey by the American Heart Association of 1000 adults discovered that 6 out of 10 thought sea salt was a low sodium alternative to table salt. Equal amounts of sea salt and table salt contain the same amount of sodium (40%). Unlke table salt, sea salt as well as Kosher salt, is generally not fortified with iodine. Iodized table salt is a leading source of iodine in U.S. diet

How else can I decrease my intake of sodium? One way is to Increase your potassium-rich foods.

The primary functions of potaasium is the same as sodium — Needed to maintain the right acid-base balance in the body. Helps maintain an approprieate amount of water in blood and body tissues, needed for muscle and nerve activity. WARNING — it is not recommended to take potassium supplements. Consequences of overdose: irregular heartbeat, heart attack.

Contents of vegetables is often reduced in processed foods. Diuretics (water pills) and other antihypertension drugs may deplete potassium. Salt substitutes often contain potassium — See your doctor.

Primary food sources: Plant foods, potatoes, sqash lima beans, tomatoes, plantains, bananas, oranges, avocados, meats, milk and milk products, coffee

Snacking on some walnuts at least once a week was associated with a 17% lower risk of stroke, according to research at Brigham and Women’s Hospital and Harvard Medical School. Walnuts are a top source of heart-healthy alpha-linolenic acid (ALA), an omega-3 fatty acid. It can help improve blood vessel function and reduced inflammation which has been shown to damage arteries. All this together helps prevent blood clots and vascular weakening.

Food and Mood? Neuronutrients

Good Mood Foods: How Diet Affects Happiness

Lani Muelrath is a bestselling author, speaker, and TV host known for her expertise in plant-based, active, and mindful living. This article is adapted from her newest book, The Mindful Vegan, a 30-day plan for shedding old thinking patterns and living more joyfully with food.

If you are presently piling plenty of colorful plants on your plate, you are already at a better mood advantage. Research tells us that plant-based diets are associated with healthier mood states. The more fruits and vegetables people eat, the happier, less depressed, and more satisfied they are with their lives. Today, we’ll focus on how, grounded in your biochemistry, eating more plants and eliminating animals and their products from your diet creates greater mental well-being and resilience.

Plantified Plate = Mood Elevator Up

A recent study of nearly 1,000 men and women examined the mood impact of obtaining dietary antioxidants. Antioxidants are health- and disease-protective bioactive chemical compounds produced by plants. In the study, those who ate three or more servings of fruits and vegetables a day reported significantly greater optimism than those who ate less. Eating lots of veggies also bumps up the B vitamins in your diet, positively affecting mood states.

Another recent, large-population, multi-wave study — taking place five times over the course of nine years — focused on the impact of fruit and vegetable intake on depression, anxiety, and mental health disorders.

Results were consistent across all five waves: greater fruit and vegetable consumption was positively associated with reduced depression, less psychological distress, fewer mood and anxiety problems, and improved perceived mental health.

Study after study corroborates. A large Swiss survey reported significant associations between higher fruit and vegetable consumption and reduced distress levels. People who ate less than the five-servings-a-day recommendation had a higher likelihood of reporting stress and anxiety than those who didn’t. A recent study on women’s health from Australia followed over 6,000 women. The findings? Reduced depression among women who simply ate more than two pieces of fruit a day. And the benefit increased when accompanied by higher intakes of vegetables.

Can Cutting Meat Improve Your Mood?

We get it — eating more plants boosts your mood. What if we look at it another way — cutting out the meat? How might that affect your state of mind? As it turns out, emotional resiliency and elevated mood states arise for more reasons than simply because you know you are doing the right thing. There’s a deeper biochemical component that underpins well-being that comes with veganizing your plate.

According to research, reduced intake of animals and their products has mood benefits in addition to those that come with a robust daily intake of fruits and vegetables. Avoiding meat, fish, and poultry leads to more frequent reports of positive states of mind. And vegans report lower anxiety and less stress than omnivores.

Inflammation and Increased Risk of Depression

Putting it all together, the Western diet — characterized by scanty consumption of plant foods, yet heavy on the animal products — is associated with increased risk of depression. Depression is related to inflammation in the body. Arachidonic acid, found only in animal products, is a precursor to inflammation. Research shows that high intakes of arachidonic acid promote changes in the brain that can disturb mood.

Here’s how it works. By eating chicken, eggs, and other animal products high in arachidonic acid, a series of chemical reactions is triggered in your body that results in inflammation. When inflammation reaches the brain, feelings of anxiety, stress, hopelessness, and depression follow. No wonder people who avoid animal flesh and products report a happier, more positive mood. And plant foods — to the rescue, once again — naturally lower inflammation due to their naturally high antioxidant content, antioxidants being one of nature’s most powerful anti-inflammatory agents.

Nutrients provide the biological building blocks for neurotransmitters — the chemicals in your brain that deeply affect how you think and feel. When you aren’t eating enough vitamins, minerals, antioxidants, polyphenols, and related nutrients found in plants — known in this context as neuronutrients — you can’t make adequate mood-enhancing transmitters. These gems of plant nutrition, by the way, are the same goodies proved to be brain protective against Alzheimer’s disease and other forms of dementia.

Diets rich in the kind of saturated fats that are abundant in animal products — and deficient in antioxidants and vitamins — appear to promote the onset of the disease, whereas diets rich in plant-plentiful vitamins, antioxidants, and polyphenols suppress its onset. All the colors plants bring to your plate are evidence of the nutrients your brain needs for better disposition. No wonder just seeing your luncheon salad makes your mood brighten.
