Omega-3 fatty acids—There are three types of omega-3 fatty acids: ALA (alpha-linolenic acid), DHA (docosahexaenoic acid), and EPA (eicosapentaenoic acid). It's recommended that all adult men and women consume 1.6 grams or 1.1 grams of ALA, respectively, each day. Both men and women should consume 500 mg of EPA and DHA per day. Some of the best food sources of omega-3 fatty acids include:
Concerned about coffee? A study in the Journal of Human Nutrition and Dietetics has concluded that daily coffee intake as part of a normal lifestyle is not associated with dehydration. Furthermore, current research suggests that regular coffee consumption may protect against cognitive impairment and decline later in life. This being said, it is good to keep in mind that water is the gold standard for hydration, and should make up a majority of fluid intake.
You can do many things on a daily basis to help ensure that your nutrition goals stay on track. First, eat regularly. Most healthcare professionals recommend that you eat three meals a day and have healthy snacks in between. Include at least three food groups with every meal. Choose fresh, plant-based foods first, eat whole grains, limit red meat, and avoid processed and high-sugar foods. Here are some additional tips:
If you experience a loss of appetite or unintentional weight loss, talk to your doctor immediately. It may be a normal sign of aging. On the other hand, it can also be caused by an underlying health condition that needs treatment. Your doctor and dietitian can also help you lose weight if excess body fat is raising your risk of chronic health conditions or straining your joints and muscles.
Your metabolism slows down. This happens naturally, but it becomes more pronounced if you don’t get as much exercise as you should. When your metabolism slows, your body doesn't burn as many calories, which means you need to eat less to stay at a healthy weight. As a result, the foods you eat should be as nutrient-rich as possible. Most women with average activity levels need about 1,800 calories per day. Men with an average activity level need about 2,300 calories each day. You’ll need fewer calories if you’re sedentary, more if you are very active.
Unfortunately, the most affordable foods are also some of the most unhealthy, so poverty can drive malnutrition. A diet that is rich in calories but bereft of nutrients will cause one to simultaneously gain weight and develop deficiency diseases (illnesses caused by lack of vitamins). This results in a bizarre phenomenon unique to developed nations, which is the presence of seniors (and sometimes adults in other age groups) who are simultaneously malnourished and overweight.
