Fats are an essential part of a healthful diet. Fats are necessary for nervous system function, energy, absorption of certain vitamins, and for skin, hair, and joint health.
Fats occur in both animal and plant foods. There are several main types of fats, and some are more healthful than others:
- Monosaturated and polyunsaturated fats are healthful fats that can boost heart health. Good sources include avocados, fish, nuts, seeds, and olives.
- Saturated fats and trans fats can raise total cholesterol and low-density lipoprotein (LDL) or “bad” cholesterol. LDL can increase the risk of heart disease. Saturated fats usually come from animal products, including cream, fatty meat, and fried foods.
The FDA recommend that people get 78 g of fat per day in a 2,000 calorie diet. People should aim to get less than 10% of their daily calories from saturated fats.
Along with choosing healthful foods from each food group, the following tips will help a person follow a healthful diet.
Tip 1: Manage portion size
People of different ages, sexes, and activity levels need different amounts of food, but many people take in more energy than they use. Research suggests that portion size is a key factor, and larger-than-needed portions lead to weight gain.
The AHA explain that a portion is what a person chooses to eat, while a serving is the amount of food manufacturers list on the nutrition facts label.
Examples of servings are one slice of bread and one wedge of melon. The AHS report that portion sizes in restaurants have increased dramatically over the years.
Tip 2: Eat fresh and avoid processed
According to a 2018 study, ultra-processed foods may make up 60%Trusted Source of the calories people eat in the U.S.
Fresh foods are more likely to be “nutrient-rich,” while processed foods are often “energy-rich” from added fats and sugars. Processed foods not only contain added ingredients, including dyes and preservatives, but the processing itself can destroy nutrients.
Whole foods, such as fresh fruit, are a good source of vitamins and minerals. Many processed foods contain little nutritional value. Consuming a high proportion of processed foods can increase the risk of heart disease and diabetes.
Tip 3: Limit added sugars
Adding sugar to foods and drinks enhances the flavor but adds little or no nutritional value. Many people in the U.S. eat too much added sugars, leading toTrusted Source weight gain, type 2 diabetes, and heart disease.
In contrast, naturally occurring sugars can have health benefits. These include fructose from fruit and lactose from dairy products.
The AHA recommend that people consume no more than 25 g of added sugars for females and 36 g for males. This amount does not include naturally occurring sugars, only added sugars.
Swapping cakes and cookies for fruit, and halving or cutting out the sugar added to coffee and tea, can reduce daily sugar intake. Condiments, such as ketchup, may also add more calories than a person realizes.
Replacing sweetened sodas with sparkling water and drinking alcohol in moderation can further reduce excess calories. The CDC recommend limiting alcohol intake to one drink per day for females and two drinks per day for malesTrusted Source.
Tip 4: Replace animal fats in the diet
Animal produce is often high in saturated fats and includes red meat, butter, cheese, and cream. Saturated fats are difficult for the body to break down, so levels of harmful cholesterol can rise, increasing the risk of heart disease.
The AHA recommend replacing foods high in saturated fats with more healthful options to lower cholesterol and improve the body’s fat profile. Healthful, unsaturated fats are in oily fish and nuts.
To reduce the amount of unhealthful fat in the diet:
- choose lean meats, such as poultry
- choose low fat dairy products
- cook meat and chicken without the skin
- limit red meat intake
- grill or boil meat instead of frying
- use vegetable oil rather than animal fat
- replace some meat servings with oily fish, nuts, beans, or legumes
Tip 5: Sodium down, potassium up
Sodium, found in salt, is directly linkedTrusted Source to high blood pressure because it increases water retention. Potassium can counteractTrusted Source the harmful effects of salt, so eating less sodium and more potassium is a change that can boost heart health.
Bananas, tuna, and butternut squash are good sources of potassium. Too much potassium can lead to irregular heart rhythms, though, so people can speak to their doctor or other healthcare practitioners before using supplements.
Limiting the intake of processed foods will reduce sodium intake, as manufacturers add salt during the processing. The majority of sodium in the American diet comes from processed and restaurant food, with relatively little coming from cooking or table salt.
To retain flavor when cutting down salt, try eating foods with herbs, such as basil, rosemary, garlic, oregano, paprika, and cayenne, or low salt condiments, such as yellow mustard. People can also buy low sodium seasonings.
Tip 6: Add calcium and vitamin D
Calcium is crucial for strengthening and maintaining bone structure. Vitamin D helps the body to absorb calcium.
While dairy is the best-known source, there are many plant-based sources of calcium.
Good sources of calcium besides dairy include:
Dietary sources do not provide enough vitamin D for the body. Sunlight is necessary to help the body synthesize vitamin D.
Exposing some bare skin to the sunlight each day will help maintain levels of calcium, and vitamin D. Here are some tips to get more vitamin D.
The most healthful diets involve eating a variety of nutrient dense foods from all major food groups, including fruits, vegetables, whole grains, protein sources, and healthful fats.
Getting the right balance of sodium and potassium will help look after the heart, and cutting down on sodium-rich and processed foods can reduce the risk of chronic health conditions.
For best results, people are best to always follow a healthful diet alongside an active lifestyle.
