Healthy Tidbits

More great tidbits to share...

Eggs
Egg yolks are home to tons of essential but hard-to-get nutrients, including choline, which is linked to lower rates of breast cancer (one yolk supplies 25% of your daily need) and antioxidants that may help prevent macular degeneration and cataracts. Though many of us have shunned whole eggs because of their link to heart disease risk, there’s actually substantial evidence that for most of us, eggs are not harmful but healthy.

Greek yogurt
Yogurt is a great way to get calcium, and it’s also rich in immune-boosting bacteria. But next time you hit the yogurt aisle, pick up the Greek kind—compared with regular yogurt, it has twice the protein (and 25% of women over 40 don’t get enough). Look for fat-free varieties. My new favorite is "Siggi's yogurt.

Salmon
Salmon is a rich source of vitamin D and one of the best sources of omega-3s you can find. These essential fatty acids have a wide range of impressive health benefits—from preventing heart disease to smoothing your skin and aiding weight loss to boosting your mood and minimizing the effects of arthritis. Unfortunately, many Americans aren’t reaping these perks because we’re deficient, which some experts believe may be at the root of many of the big health problems today, like obesity, heart disease, and cancer.
Omega-3s also slow the rate of digestion, which makes you feel fuller longer, so you eat fewer calories throughout the day.

Beef
Lean beef is one of the best-absorbed sources of iron there is. (Too-little iron can cause anemia.) Adding as little as 1 ounce of beef per day can make a big difference in the body’s ability to absorb iron from other sources, says Mary J. Kretsch, PhD, a researcher at the USDA-ARS Western Human Nutrition Research Center in Davis, CA. Beef also packs plenty of zinc (even minor deficiencies may impair memory) and B vitamins, which help your body turn food into energy.
If you can, splurge on grass-fed. Compared with grain-fed beef, it has twice the concentration of vitamin E, a powerful brain-boosting antioxidant. It’s also high in omega-3 fatty acids. Because this type of beef tends to be lower in overall fat, it can be tough—so marinate it, and use a meat thermometer to avoid overcooking.

Beans
It’s hard to imagine a more perfect food than beans. One cooked cupful can provide as much as 17 g fiber. They're also loaded with protein and dozens of key nutrients, including a few most women fall short on—calcium, potassium, and magnesium. Studies tie beans to a reduced risk of heart disease, type 2 diabetes, high blood pressure, and breast and colon cancers.

The latest dietary guidelines recommend consuming at least 3 cups of beans a week. Keep your cupboards stocked with all kinds: black, white, kidney, fat-free refried, etc. Use them in salads, stuffed baked potatoes, and veggie chili or pureed for sandwich spreads.

Nuts
In a nutshell: USDA researchers say that eating 1½ ounces of tree nuts daily can reduce your risk of heart disease and diabetes. Walnuts are rich in omega-3s. Hazelnuts contain arginine, an amino acid that may lower blood pressure. An ounce of almonds has as many heart-healthy polyphenols as a cup of green tea and 1/2 cup of steamed broccoli combined; they may help lower LDL cholesterol as well.

The key is moderation, since nuts are high in calories. Keep a jar of chopped nuts in your fridge, and sprinkle a tablespoon on cereal, salads, stir-fries, or yogurt. Or have an ounce as a snack most days of the week.

Soy
Soy’s days as a cure-all may be over—some claims, such as help for hot flashes, don’t seem to be panning out—but edamame still has an important place on your plate. Foods such as tofu, soy milk, and edamame help fight heart disease when they replace fatty meats and cheeses, slashing saturated fat intake. Soy also contains heart-healthy polyunsaturated fats, a good amount of fiber, and some important vitamins.

Soy’s isoflavones, or plant estrogens, may also help prevent breast cancer. Some researchers believe these bind with estrogen receptors, reducing your exposure to the more powerful effects of your own estrogen, says Prevention advisor Andrew Weil, MD. But stick with whole soy foods rather than processed foods, like patties or chips, made with soy powder. Don’t take soy supplements, which contain high and possibly dangerous amounts of isoflavones.

Flax
Flaxseed is the most potent plant source of omega-3 fats. Studies indicate that adding flaxseed to your diet can reduce the development of heart disease by 46%—it helps keep red blood cells from clumping together and forming clots that can block arteries. It may also reduce breast cancer odds. In one study, women who ate 10 g of flaxseed (about 1 rounded tablespoon) every day for 2 months had a 25% improvement in the ratio of breast cancer–protective to breast cancer–promoting chemicals in their blood.

Sprinkle 1 to 2 tablespoons of flaxseed a day on your cereal, salad, or yogurt. Buy it preground, and keep it refrigerated.

    I love "Healthy Tidbits". I just bought my first Greek yogurt last week. Love the info on eggs. My breakfast for the past year has consisted of two table spoons of organic flax seed that I grind every morning and eat it with 1/2 cup of non fat organic milk and a teaspoon of organic cinnamon, two organic poached eggs, organic sprouted whole wheat toast, and a slice of organic deli turkey meet. The turkey meet is a little high in sodium so I'm going to phase it out. Love your blog.

    Thanks,
    Clara
