Ask Doc

I don't know you.

So that means I can't tell you precisely which credit card, stock recommendation, or diet is best for you.

After our issue on the dangers of fish-oil supplements, we got dozens of variations on the same question. Here's just one...

Wondering what your opinion of krill oil is compared with fish oil as a supplement. I've been taking 100% krill oil capsules for a few years now. Krill are lower in the food chain so theoretically don't have as many toxins in them. – B.B.

About 15 years ago, while I was researching genetic eye diseases at Duke, I met a publisher named Porter Stansberry.

He convinced me to write to his readers about what I learned during my careers in finance and medicine. Our initial conversations turned into a much bigger idea...

A subscriber wrote in yesterday morning with a couple of great points...

New subscriber from January 2016 and loving the option concept. Thank you for your tutelage.

No one teaches much truth about what's healthy in your diet.

Exercise gurus claim to be a source on what's natural... but they're usually selling diet books and pills.

Even mainstream organizations like the American Diabetes Association regularly get confused about the science. When I was in medical school, they still recommended things like white flour buns, white rice, and a couple of packets of sugar in coffee on hospital dinner trays.

Fruit is a food group that is occasionally villainized because of sugar. So I wasn't surprised when some readers asked why I keep telling people to eat more fruit. As I've written many times over the years, moderation is key. Blueberries are an incredibly healthy food packed with nutrients. Just don't eat too many at once...

Today, I'll talk more about my No. 1 superfood, ways to supplement your retirement income, why there's no substitute for floss, and transportation alternatives for seniors.

Q: What would be a daily recommended portion size [of blueberries] to eat? – J.V.

A: I like to have blueberries throughout the day. In the morning, I'll eat blueberries in my cereal, oatmeal, and yogurt. And in the evening, I keep some fruit – including blueberries – close by for snacking. In total, I eat about a half-cup of blues per day.

Q: We have taken your advice and have started eating our blues with active culture yogurt – Fage and Latta Russian Kefir from Wegmans. We do rinse our blues (a pint at a time) when we get them home and store them in a glass bowl with a plate on top. We also rinse the ones we freeze. But before putting them in freezer bags we dry them on a cookie sheet. Your thoughts on our methods please. – J.S.

A: Your method is just fine. The key is to not rinse too many at once. As I mentioned, washing berries makes the skin soggy and speeds up the pace of mold growth. If you freeze the berries right after rinsing them, you should be fine. Instead of letting them sit around for too long, just use some paper towels to give them a quick dry.

This week, a reader wrote in with a request: "Please stop saying, 'Do like I do.'"

It's a phrase my longtime subscribers know well. It's become a catchphrase of mine.

We're no strangers to controversy here at Retirement Millionaire Daily.

But we were shocked at the feedback we got this week.

In the office, they call me "the codger."

It's meant in good humor, but as with most jokes, it carries a bit of truth...

Doc, I think we started a revolution...

That was the response of both my assistants after they read through the flood of messages we received after our last Q&A issue of Retirement Millionaire Daily.

I'm sick of this mindless mantra...

On Wednesday, the Food and Drug Administration ("FDA") published guidelines to bully the food industry into lowering sodium levels in foods to "recommended" levels. It's a huge overreach of government power.
