Here's an eye-opening statistic: older Americans are more afraid of running out of money than of death itself.

And older Americans have legitimate reasons for this worry, even if they have dutifully saved for their golden years. That\s because the traditional ways people manage retirement may no longer provide enough income to meet expenses- and with people generally living longer, the principal retirement savings is exhausted far too early in the retirement period.

The tried - and - true retirement investing approach of yesterday doesn't work today.

Years ago, investors at or close to retirement could put money into fixed-income assets and depend on appealing yields to generate consistent, solid pay streams to fund a comfortable retirement. 10-year Treasury bond rates in the late 1990s floated around 6.50%, but unfortunately, those days of being able to exclusively rely on Treasury yields to fund retirement income are over.

That means if you had $1 million in 10-year Treasuries, the difference in yield between 1999 and today is more than $1 million.

Today's retirees are getting hit hard by reduced bond yields-and the Social Security picture isn't too rosy either. Right now and for the near future, Social Security benefits are still being paid, but it has been estimated that the Social Security funds will be depleted as soon as 2035.

How can you avoid dipping into your principal when the investments you counted on in retirement aren't producing income? You can only cut your expenses so far, and the only other option is to find a different investment vehicle to generate income.

Invest in Dividend Stocks

We feel that these dividend-paying equities-as long as they are from high-quality, low-risk issuers-can give retirement investors a smart option to replace low-yielding Treasury bonds (or other bonds).

Look for stocks that have paid steady, increasing dividends for years (or decades), and have not cut their dividends even during recessions.

A rule of thumb for finding solid income-producing stocks is to seek those that average 3% dividend yield, and positive yearly dividend growth. These stocks can help combat inflation by boosting dividends over time.

Here are three dividend-paying stocks retirees should consider for their nest egg portfolio.

Canadian Natural Resources (CNQ Quick QuoteCNQ - Free Report) is currently shelling out a dividend of $0.45 per share, with a dividend yield of 3.69%. This compares to the Oil and Gas - Exploration and Production - Canadian industry's yield of 0% and the S&P 500's yield of 1.29%. The company's annualized dividend growth in the past year was 11.1%.

But aren't stocks generally more risky than bonds?

Overall, that is true. But stocks are a broad class, and you can reduce the risks significantly by selecting high-quality dividend stocks that can generate regular, predictable income and can also decrease the volatility of your portfolio compared to the overall stock market.

Combating the impact of inflation is one advantage of owning these dividend-paying stocks. Here's why: many of these stable, high-quality companies increase their dividends over time, which translates to rising dividend income that offsets the effects of inflation.

Thinking about dividend-focused mutual funds or ETFs? Watch out for fees.

If you prefer investing in funds or ETFs compared to individual stocks, you can still pursue a dividend income strategy. However, it's important to know the fees charged by each fund or ETF, which can ultimately reduce your dividend income, working against your strategy. Do your homework and make sure you know the fees charged by any fund before you invest.

Bottom Line

Pursuing a dividend investing strategy can help protect your retirement portfolio. Whether you choose to invest in stocks or through low-fee mutual funds or ETFs, this approach can potentially help you achieve a more secure and enjoyable retirement.
