Walnuts

Why: It takes a bit of work to crack the hard shell and get the goods, but once you do they're worth it. Besides their great taste, walnuts are known for their high antioxidant activity. Antioxidants help offset the detrimental effects of oxidation, a process that is constantly occurring in the body and is a primary cause of aging. In a study reported in the American Journal of Clinical Nutrition, walnuts ranked second only to blackberries (out of 1,113 foods tested) in antioxidant activity. Oh, and are you having trouble sleeping? Get this: Walnuts are the richest known food source of melatonin.

Nutrients: Walnuts contain many essential vitamins and minerals. A 1-ounce serving is a good source of phosphorus and magnesium and an excellent source of copper. There are also 2 grams of fiber and a decent percentage of niacin, thiamine, vitamin B6, vitamin E, zinc and potassium.


Health Perks: This is the only nut that contains a significant amount of omega-3s — 2.6 grams in 1 ounce. Plant sources of omega-3s benefit the skeletal system by decreasing the breakdown of bone. Eating an ounce of walnuts (to replace other calories, not in addition to your diet) every day will lower your LDL “bad” cholesterol and improve circulation. Walnuts also play a role in decreasing blood pressure and reducing inflammation associated with heart disease.

Nutrition Stats: (1 ounce, 14 halves or ¼ cup) 185 calories, 18.49g fat, 3.89g carbohydrates, 4.32g protein, 1.9g dietary fiber

Purchasing: Fresh walnuts taste — and smell — sweet and mildly nutty. They are most readily available during the fall and winter months.

Storage: When walnuts are harvested, they are kept in cool, dry storage until they are shipped to retail stores. They are rich in polyunsaturated fat, which, when exposed to heat, oxidizes quickly, so shelled or chopped walnuts should be stored in a sealed container away from sunlight and in a cool, dry place. Refrigerator storage is good, but if you have larger quantities, freezer storage is best. Walnuts from opened packages keep well for up to six months when they are refrigerated in sealed containers, or for up to a year in the freezer.

Recipe: Grilled Mushroom and Walnut Salad

Servings: 4

Ingredients

- 2 heads butter, Boston or bibb lettuce

- 1/2 pound green beans, ends trimmed

- 2 shallots, minced

- 1/8 teaspoon each dried rosemary and thyme

- 1/8 teaspoon coarsely ground black pepper

- 12 shiitake (or any large domestic) mushrooms, stems removed

- 1/2 cup (2 ounces) shredded fat-free Cheddar cheese, loosely packed

- 1/2 cup coarsely chopped California walnuts

- 1 lemon, cut into wedges

- 2 small tomatoes, quartered (Roma preferred)

- 1/2 cup fat-free dressing

Preparation

- Clean, core and carefully separate leaves of lettuce.  Place in a large mixing bowl, cover with a damp cloth and chill.

- Bring a large pot of water to a boil.  Fill a large bowl with ice water.  Cut green beans into 1/2-inch diagonals and blanch in boiling water for 30 seconds.  Using tongs or a slotted spoon, transfer green beans from boiling water to ice water.  Drain; set aside.  (OR combine green beans with 2 tablespoons water on a microwave-safe platter; cover with vented plastic wrap.  Microwave on high 3 to 4 minutes, stirring once.)

- Combine shallots, herbs and pepper in a small bowl.  Add mushrooms; let marinate for 5-10 minutes. 

- Grill mushrooms over a hot grill, 2 minutes on each side.  (Mushrooms may be broiled if no grill is accessible.)  Remove from heat.  Let cool 2-3 minutes.

- Arrange bibb lettuce "cups" on four plates.  Place grilled mushrooms in each lettuce cup; add green beans. 

- Top with shredded cheese and chopped walnuts.  Garnish each salad with a lemon wedge and 2 tomato quarters.

- Serve with fat-free dressing.

Almonds

Why: Almonds are available in more forms than any other nut. For any course and ethnic cuisine, there’s bound to be an appropriate form or culinary technique. Actually the seeds of the almond tree, they are delicious whether you eat them alone as a snack or sliced as a tasty accent in your food.

Nutrients: A handful (about 1 ounce) is an excellent source of vitamin E and magnesium, a good source of protein, riboflavin and fiber, and also offers significant quantities of potassium, calcium, phosphorous, iron and monounsaturated fat.

Health Perks: An analysis of seven clinical studies found that eating 1 ounce of almonds daily as part of a healthy lifestyle lowers LDL cholesterol, thereby reducing the risk of heart disease. Additionally, other studies have shown that higher intakes of magnesium-rich foods like almonds may help maintain blood sugar and insulin levels, particularly after eating a carbohydrate-rich meal.

Nutrition Stats: (1 ounce, 23 whole almonds) 164 calories, 14.36g fat, 5.6g carbs, 6g protein, 3.3g fiber

Purchasing: If you want long-lasting almonds, buy those that are still in the shell or in a sealed container (and make sure they don’t contain any added ingredients). Keep in mind that there are bitter and sweet almonds. Those typically found in stores are from California and are almost always sweet.

Storage: Store under cool and dry conditions in an airtight container. Avoid exposure to strong odors as almonds can absorb odors from other materials if exposed for prolonged periods. Almonds can stored be for about two years with no significant loss in quality.

Please address the conflict between eating nuts and hypothyroidism. I have found that many foods, recommended for lowering cholesterol, interfere with the function of the thyroid and reduce the action of thyroid medications.



what foods lower cholesterol and do not impact the thyroid?

I use chopped walnuts and toasted whole almonds every day. I buy a smaller bag of the chopped walnuts on the baking isle and raw shelled almonds in the produce area of the grocery store. I toast my own almonds, I toast mine a 300 degrees for 30 minutes. I cool the almonds and mix with the chopped walnuts and store in the large saved yogurt containers. These nuts go on my steel ground oatmeal in the morning, on my pear and cottage cheese salad at lunch and on a snack of yogurt and fruit in the evening.

For optimal health value, eat all nuts and seeds RAW, thereby not adding unhealthful roasting fat and/or sodium to your intake.
