Ever wonder why it is so important to eat for your health?
Not sure what exactly to eat to properly nourish your body?
This article by Medical News Today is very helpful.
A healthful diet includes a variety of fruits and vegetables of many colors, whole grains and starches, good fats, and lean proteins.
Eating healthfully also means avoiding foods with high amounts of added salt and sugar.
Here we look at the top 10 benefits of a healthful diet, as well as the evidence behind them.
1. Weight loss
There are many benefits to eating healthfully.
Losing weight can help to reduce the risk of chronic conditions. If a person is overweight or obese, they have a higher risk of developing several conditions, including:
heart disease
non-insulin dependent diabetes mellitus
poor bone density
some cancers
Whole vegetables and fruits are lower in calories than most processed foods. A person looking to lose weight should reduce their calorie intake to no more than what they require each day.
Determining an individual's calorie requirements is easy using dietary guidelines published by the United States government.
Maintaining a healthful diet free from processed foods can help a person to stay within their daily limit without having to count calories.
Fiber is one element of a healthful diet that is particularly important for managing weight. Plant-based foods contain plenty of dietary fiber, which helps to regulate hunger by making people feel fuller for longer.
In 2018, researchers found that a diet rich in fiber and lean proteins resulted in weight loss without the need for counting calories.
2. Reduced cancer risk
An unhealthful diet can lead to obesity, which may increase a person's risk of developing cancer. Weighing within a healthful range may reduce this risk.
Also, in 2014, the American Society of Clinical Oncology reported that obesity contributed to a worse outlook for people with cancer.
However, diets rich in fruits and vegetables may help to protect against cancer.
In a separate study from 2014, researchers found that a diet rich in fruits reduced the risk of cancers of the upper gastrointestinal tract. They also found that a diet rich in vegetables, fruits, and fiber lowered the risk of colorectal cancer and that a diet rich in fiber reduced the risk of liver cancer.
Many phytochemicals found in fruits, vegetables, nuts, and legumes act as antioxidants, which protect cells from damage that can cause cancer. Some of these antioxidants include beta-carotene, lycopene, and vitamins A, C, and E.
Trials in humans have been inconclusive, but results of laboratory and animal studies have linkedcertain antioxidants to a reduced incidence of free radical damage associated with cancer.
