4 Diet mistakes that age you

What if the fountain of youth were in your own kitchen? While we’ve come to expect certain physical and mental changes as an inevitable part of getting older, the fact is that the foods we eat—or don’t—may speed those processes along, aging us before our time. The reason is simple: “We eat too many processed foods,” says David Katz, MD, director of Yale University’s Prevention Research Center. “They’re often high in calories and low in nutrients such as vitamin B12 and omega-3s, so we end up with islands of deficiencies in a sea of excess.” These inadequacies can result in symptoms we tend to assume are due to aging, such as the four below. Work with your doctor to determine whether adjusting your diet or adding a supplement can help you look—and feel—younger.
Mistake #1: You avoid all animal protein.
Why it’s aging you: You may lack of vitamin B12. which is essential for energy.

Found only in foods that are derived from animals, this nutrient helps regulate your metabolism and energy production and is key to maintaining a healthy brain and nervous system. “Fatigue is a classic sign of B12 deficiency, which usually occurs in people who don’t eat very much animal protein,” says Danine Fruge, MD, associate medical director of the Pritikin Longevity Center & Spa in Miami. Chewing a lot of antacids to relieve heartburn can also lead to B12 deficiency because antacids interfere with B12 absorption.

Food Fix: Have two servings of nonfat dairy foods, such as fat-free milk or nonfat yogurt, and 3 to 4 ounces of lean protein daily. Good sources of B12 include seafood such as fish, clams, oysters, and mussels, as well as lean beef and pork, chicken, and fortified cereal.
Supplement Solution
Take 500 to 1,000 mcg of vitamin B12 in tablet form every day to raise and maintain your B12 levels.

Mistake #2: You avoid supplements.
Why it’s aging you: You miss manganese and copper, which help prevent joint pain.
Because manganese and copper are both essential for maintaining joint cartilage and flexibility, “in most cases, supplementing these nutrients reverses the joint deterioration and eliminates the pain,” says Dale Peterson, MD, director of the Comprehensive Wellness Center in Sapulpa, OK. “The body can actually repair a significant amount of damage if it’s given the proper support.”

Food Fix: Nuts, beef, and spinach are good sources of these nutrients, but you won’t be able to eat enough to get all your copper and manganese, so opt for a supplement, Dr. Peterson advises. Take 2 mg of copper and 5 mg of manganese each day. Within 2 to 3 months, your joints should feel less painful.

Supplements that help you avoid disease
Mistake #3: You avoid fish and fat.
Why it’s aging you: Fish and healthy oils (like olive) offer the best source of omega-3 essential fatty acids ,which help prevent memory loss.
“These fatty acids are part of the brain’s building blocks,” explains Andrew Weil, MD, director of the Center for Integrative Medicine at the University of Arizona. “If you’re not getting enough in your diet, the architecture of the brain becomes weak, and brain function, including memory, suffers.” But it’s not only the amount of omega-3s that’s important; the balance between omega-3s and omega-6s is equally crucial. “Our diets are flooded with omega-6 fatty acids, mostly from processed foods,” says Dr. Weil. “The more omega-6s you eat, the more omega-3s you need to balance your levels. Most of us aren’t eating enough omega-3s and are eating too many omega-6s.”

Food Fix: First, reduce your consumption of refined and processed foods much as possible, and cook with olive or canola oil. Then, eat 3 1⁄2 ounces of wild salmon and 3 1⁄2 ounces of herring, sardines, or halibut each week. Add 2 tablespoons of freshly ground flaxseed to cereal, whole grain side dishes, or shakes daily, and garnish salads or cereal with 1 tablespoon of walnuts 5 days a week. Finally, enjoy 9 to 12 almonds 4 times a week.
Supplement SolutionTake at least 2,000 mg of fish oil daily.
Look for 1,000 mg capsules of combined docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).
Mistake #4: You favor packaged foods over whole.
Why it’s aging you: Packaged foods are high in blood pressure–spiking sodium—and fresh fruits and veggies contain blood pressure–lowering potassium.

“Having too little potassium in your diet magnifies the toxic effects of excessive salt intake,” Dr. Fruge says. Most processed foods have added sodium but no extra potassium, so if your meals come from boxes, you’re likely at risk. Worsening the situation, when your kidneys try to flush out the salt, you lose even more potassium. “The imbalance damages blood vessels, driving up blood pressure,” Dr. Fruge notes. “Eating better can correct the problem—I’ve seen people drop thirty points in three days.”

Food Fix: Cut your sodium consumption to no more than 1,500 mg per day, and eat seven to nine servings of fruits and vegetables every day.

Brilliant Pacquiao’s prime is being squandered

The fans at the MGM Grand Garden Arena in Las Vegas poured boos down on the ring, expressing a sentiment shared by many pay-per-view customers. Sugar Shane Mosley was running from Manny Pacquiao, making consumer disappointment and anger understandable.
So too was this emotion: sadness.
Saturday was another wasted night of Pacquiao’s prime, the competitive circumstances and raw politics of boxing robbing what could’ve been a night of greatness tested.
Instead, we got another lopsided decision, Pacquiao winning as an overwhelming favorite against a 39-year-old opponent who had no intention of actually fighting.
Mosley was once a great champion and remains a likable ambassador for the sport. He never stood a chance against Manny, though. That was something promoter Bob Arum acknowledged at the outset, only to realize he was so out of opponents for the Filipino that he had to make the fight anyway.
Mosley was the second of Pacquiao’s last three opponents to enter the ring and not even attempt to win. Fourteen months ago Joshua Clottey covered up for 12 rounds. Even after he was shut out on the scorecard, Clottey lifted his arms in triumph and posed for pictures with his team. The goal was to survive, not actually box.
Before you blame Clottey and Mosley, consider what happened to the last several guys who decided to stand and trade with Manny:
Antonio Margarito, pummeled repeatedly, broken orbital bone, sent to hospital, career in jeopardy. Miguel Cotto, pummeled repeatedly, TKO’d, sent to hospital. Ricky Hatton, knocked out cold, sent to hospital, hasn’t fought since. Oscar De La Hoya, pummeled repeatedly, TKO’d, sent to hospital, hasn’t fought since. David Diaz, pummeled repeatedly, TKO’d, sent to hospital.
We could go on. Manny Pacquiao hasn’t lost a fight in six years.
And he probably isn’t losing one anytime soon, leaving fans stuck watching an iconic fighter dominate inferior opponents just for the sake of watching said icon.
Sadness isn’t a new feeling in boxing. It’s just usually reserved for those horrific nights when an aging champion is getting battered by the sport’s inevitable, and swift, circle of life. It’s sad to watch greatness gone. It’s sad to fear the damage done.
This is completely different – sadness born from frustration. It’s like watching Michael Jordan playing minor league basketball, cheating everyone from years of thrilling moments and memories on the basketball court.
Critics of boxing are always saying it needs charismatic headliners. Well, what then is Manny Pacquaio? He’s willing to fight exciting fights, test himself against bigger, stronger men. He smiles. He laughs. He’s smart. He has a real life as an elected politician. He sings on late-night talk shows and performs fan concerts after fights. There’s almost nothing like him in sports. And Saturday, Top Rank put on a great show around him, complete with a rare entertaining undercard featuring the return of ex-champ Kelly Pavlik and a dramatic 12th round, come-from-behind-TKO by Jorge Arce of Wilfredo Vazquez, Jr.
Then the main event bombed, the cold reality of the era ruining everything.
Arum talked about a potential November fight between Pacquiao and Juan Manuel Marquez, who earned a draw with Pacman in 2004 and lost a close decision in 2008. Those bouts took place in the featherweight or super featherweight divisions, however. That’s 20 pounds ago for Pacquiao, who fought at 147 on Saturday.
Marquez is a warrior, but he struggled to get to 142 pounds when he was outclassed by Floyd Mayweather Jr. in 2009. It was Mayweather’s un-retirement fight and considered a somewhat safe one because Marquez was so small. If he’s too small for Floyd, then he’s of little threat to the 2011 version of Manny.
Marquez would also become the fourth recent Pacquiao opponent first “softened up” by Mayweather, joining De La Hoya, Hatton and Mosley.
The obvious solution is to get Pacquiao and Mayweather in the ring together and stage the richest fight in history. Then do it again in a rematch. That seems less likely now than ever, though. Mayweather hasn’t fought anyone in over 13 months and spent Saturday night, he claims, watching a Lady Gaga concert on cable.
We should be in the middle of an epic trilogy between these two – their styles seemingly perfectly suited to challenge each other. It’s rare when the two best pound-for-pound fighters of a decade are essentially the same weight. Yet money, pride, politics, bad blood, allegations of doped blood, slander suits, domestic violence charges and all sorts of other nonsense stand in the way.
We’ve been through the Mayweather-Manny debate before. Right now, it isn’t getting solved. It may never.
So we get what we get and the crowd gets upset.
“What could I do if my opponent doesn’t want to fight toe-to-toe? It’s not my fault,” Pacquiao argued, and really no one was blaming him. “I’m happy, because I know I won the fight. But I said my first concern is the satisfaction of the people. I want the people to be satisfied with my performance and to leave happy.”
The Mosley fight should never have been made. Same with Clottey. And it’ll be the same with Marquez.
There is virtually no one left for Pacquiao to fight. He’ll still get big numbers at the gate and on pay per view because he’s such an attraction, such a talent, but it increasingly feels like a waste of time. He’s stuck in B-grade bouts. You can’t shine a sneaker.
Zab Judah is another option, but he’s lost to Clottey, Cotto and Mayweather.
Timothy Bradley, the dynamic, unbeaten, 27-year-old Californian, is a potential long-term challenger to Pacquiao. Is he ready to step up as soon as November? He may have to be. For my money, it’s the most intriguing fight.
At least Bradley is a fresh face. At least he has a future. At least, we presume, he’ll stand up and actually try to win.
These days with Pacquiao that’s all we can hope for; a sad indictment on a sport that is stalling when it should be soaring.

Samoa to go Back to the Future, shifting date line

APIA, Samoa – Samoa plans to leap 24 hours into the future, erasing a day and putting a new kink in the Pacific's jagged international date line so that it can be on the same weekday as Australia, New Zealand and eastern Asia.
It'll be Back to the Future for the island nation, offsetting a decision it made 119 years ago to stay behind a day and align itself with U.S. traders based in California.
That has meant that when it's dawn Sunday in Samoa, it's already dawn Monday in adjacent Tonga and shortly before dawn Monday in nearby New Zealand, Australia and increasingly prominent eastern Asia trade partners such as China.
Samoa has found its interests lying more with the Asia-Pacific region and now wants to switch back to the west side of the line, which separates one calendar day from the next and runs roughly north-to-south through the middle of the Pacific Ocean.
"In doing business with New Zealand and Australia we're losing out on two working days a week," Prime Minister Tuilaepa Sailele Malielegaoi said in a statement. "While it's Friday here, it's Saturday in New Zealand and when we're at church on Sunday, they're already conducting business in Sydney and Brisbane."
Samoa's change will have a cost: The Polynesian nation has long marketed itself as the last place on Earth to see each day's sunset.
"It will be really confusing for us. I just don't see the point, and we don't know the benefits yet," multimedia company official Laufa Lesa, 30, told The Associated Press in an interview from the Samoan capital Apia.
"The government says it's good for the economy, but it's totally fine the way it is now," Lesa said.
The prime minister already has a new tourism angle: You can easily celebrate the same day twice, because the next-door U.S. territory of American Samoa will stay on the California side of the date line and remain one day behind.
"You can have two birthdays, two weddings and two wedding anniversaries on the same date — on separate days — in less than an hour's flight across (the ocean), without leaving the Samoan chain," Tuilaepa said.
Tuilaepa has proposed leaping forward by scratching this year's Dec. 31 from the calendar and holding New Year's celebrations one night early, though the date hasn't been confirmed.
The original shift to the east side of the line was conducted in 1892 when Samoa celebrated July 4 twice, giving a nod to Independence Day in the U.S.
The date line drawn by mapmakers is not mandated by any international body. By tradition, it runs roughly through the 180-degree line of longitude, but it zigzags to accommodate choices of Pacific nations on how to align their calendars.
Nearly as many Samoans now live in Australia and New Zealand as the 180,000 living in the islands, which are located about halfway between New Zealand and Hawaii and rely on fruit and vegetable exports as well as tourism.
In 2009, Tuilaepa enacted a law that switched cars to driving on the left side of the road instead of the right, also to bring Samoa in line with Australia and New Zealand. He said at the time the change made it easier for Samoans in Australia and New Zealand to send used cars home to their relatives. Opponents predicted major traffic problems, but they never happened.
"Today we do a lot more business with New Zealand and Australia, China and Pacific Rim countries such as Singapore," the prime minister said, adding that his latest idea will make commerce with the region "far, far easier."
