Q & A

10 Most Popular Diet & Nutrition Questions Answered by Dr. Lama Al Nael

 Dietary fiber from fruits, vegetables, whole grains, and legumes can help maintain a healthy weight, lower blood cholesterol, and glucose levels, help food pass through the digestive system, promote regularity and prevent constipation. Aim for at least 25 grams per day.

Try drinking a glass upon waking and one with every meal. For a flavor boost, add a spritz of citrus, like lemon or lime. Proper hydration is vital for health. It helps regulate body temperature, removes waste, lubricates joints, helps prevent infections, shuttles nutrients to cells and helps organs function properly.

Those who eat breakfast tend to eat less throughout the day, and studies have shown that breakfast improves cognitive performance, especially in school-age children. Skipping breakfast may leave you feeling tired and hungry, which can lead to poor dietary choices.

Fill up on nutrients the body needs—vitamins, minerals, complex carbs, lean protein, and healthy fats—by eating a varied diet of nutrient-dense foods like fruits, vegetables, whole grains, lean meats, eggs, beans, and nuts.

Unsaturated fats, like monounsaturated and polyunsaturated, that can lower your risk for heart disease or stroke are considered good for you. For monounsaturated fats, think olive, canola, peanut, and sunflower oils, as well as avocados and most nuts. Polyunsaturated fats are in corn and soybean oils and in walnuts, sesame, pumpkin and flax seeds. Omega-3 fatty acids are a type of polyunsaturated fat in salmon, mackerel, tuna, and trout.

At least half your plate should consist of fruits and vegetables. You can't get all the nutrients you need from a single fruit or vegetable, so it's important to consume a variety of both. Men and women between the ages of 19 and 50 should aim for 2-1/2 to 3 cups of veggies per day and 1-1/2 to 2 cups of fruit.

Tiny microbes referred to as probiotics in fermented foods, like yogurt, may aid digestive function, regularity and improve overall immune health. Prebiotics can affect the growth of immune-boosting helpful bacteria throughout your gastrointestinal tract.

Adults need a minimum of .8 grams of protein per kilogram of body weight per day, or a little more than 7 grams of protein per 20 pounds of body weight. Athletes and those who exercise regularly will need more. Protein is found throughout the body, and is critical for cell and organ function, as well as repairing and rebuilding muscle tissue after exercise.

Go for fruit, like grapes, mandarin oranges, or berries. Also, try red pepper strips with hummus or celery with natural nut butter. A little jerky and snack-size amount of cheese is a high-protein option.

Most health experts agree that up to 400 mg per day is safe for average adults. However, expecting mothers and small children should limit caffeine intake. An 8-oz cup of coffee contains about 100 mg of caffeine, while a 12-oz soda contains about 50 mg.
