7 Keys to a Healthy Diet

1
Consume a Variety of Foods

Not all the nutrients and other substances in foods that contribute to good health have been identified, so eating a wide assortment of foods helps ensure that you get all of the disease-fighting potential that foods offer. In addition, this will limit your exposure to any pesticides or toxic substances that may be present in a particular food.
2
Keep an Eye on Portions

Sure, you can eat all the broccoli and spinach you want, but for higher-calorie foods, portion control is the key. In recent years, serving sizes have ballooned. In restaurants, choose an appetizer instead of an entree or split a dish with a friend. Don’t order anything that’s been “supersized.” When reading food labels, check serving sizes: some relatively small packages claim to contain more than one serving, so you have to double or triple the calories, grams of fat and milligrams of sodium if you’re planning to eat the whole thing.
3
Eat Plenty of Produce

Aim for 2½ cups of vegetables and 2 cups of fruit a day, for a 2,000-calorie diet. If you consume more calories, aim for more; if you eat fewer than 2,000 calories, you can eat less. Include green, orange, red, blue/purple and yellow produce. The nutrients, fiber and other compounds in these foods may help protect against certain types of cancer and other diseases. Legumes, rich in fiber, count as vegetables, though are moderately high in calories. Choose whole fruits over juice for more fiber. Frozen and canned fruits and vegetables are good options.

Memory loss: 7 tips to improve your memory

Concerned about memory loss? Take heart. Simple steps — from staying mentally active to including physical activity in your daily routine — might help sharpen your memory.
By Mayo Clinic Staff

Can't find your car keys? Forget what's on your grocery list? Can't remember the name of the personal trainer you liked at the gym? You're not alone. Everyone forgets things occasionally. Still, memory loss is nothing to take lightly.

Although there are no guarantees when it comes to preventing memory loss or dementia, memory tricks can be helpful. Consider seven simple ways to sharpen your memory — and know when to seek help for memory loss.
1. Stay mentally active

Just as physical activity helps keep your body in shape, mentally stimulating activities help keep your brain in shape — and might keep memory loss at bay. Do crossword puzzles. Read a section of the newspaper that you normally skip. Take alternate routes when driving. Learn to play a musical instrument. Volunteer at a local school or community organization.
2. Socialize regularly

Social interaction helps ward off depression and stress, both of which can contribute to memory loss. Look for opportunities to get together with loved ones, friends and others — especially if you live alone. When you're invited to share a meal or attend an event, go!
3. Get organized

You're more likely to forget things if your home is cluttered and your notes are in disarray. Jot down tasks, appointments and other events in a special notebook, calendar or electronic planner. You might even repeat each entry out loud as you jot it down to help cement it in your memory. Keep to-do lists current and check off items you've completed. Set aside a certain place for your wallet, keys and other essentials.

Limit distractions and don't try to do too many things at once. If you focus on the information that you're trying to remember, you'll be more likely to recall it later. It might also help to connect what you're trying to remember to a favorite song or another familiar concept.
