Low-Fat Diet - An Overview

Introduction:

The general rule is that if a diet provides 100 calories and has three grams or less fat, it is low-fat. These foods where thirty percent or less of calories come from fat will help lower the risk of developing cardiovascular morbidity and mortality. In a generally healthy diet, fat is the primary fuel source for the body because it provides the body with vital minerals, vitamins, and essential fatty acids.

Why Start a Low-Fat Diet?

The doctor will recommend a low-fat diet in case of troubled indigestion or absorbing fat, gallstones, or pancreatitis because it reduces the amount of fat one eat by avoiding high-fat foods and choosing low-fat options. It is still important to enjoy various nutritious food from each food group.

Given below are the foods that are high in fat content:

• Fixed food and fatty meat.

• Pastries, cakes, pies and chocolate.

• Butter, margarine, cream, and oils.

How to Reduce Low-Fat Food Intake?

Low-fat food can be consumed in the following ways:

• Use low-fat cooking methods like poaching, grilling, or baking instead of frying.

• Low-fat foods include plenty of fresh fruits, vegetables, and legumes, as most of these foods are fat-free.

• Instead of using oil and butter sparingly, cooking oil sprays can be used.

• Limiting high-fat takeaway foods

• Choosing low-fat dairy products.

• Trimming visible fat from meat, removing chicken skin, and avoiding high-fat processed meats like salmon, sausages, or daily meats.

What are a few Examples of High Protein and High Energy Foods and Drinks Which Have Low Fat Diet?

When following a low-fat diet, people are losing weight without trying, then have more low-fat, high-protein, and high-energy foods and drinks such as:

• Baked beans, canned tuna.

• More lean meat or chicken (ex-chicken burst, lean mince).

• Skimmed milk with extra skimmed milk powder.

• Low-fat yogurt, custard, ice cream, soya milk.

• Fruit juices, cordial soft drinks, lollies.

• Bread or crumpet with honey or jam.

What Are the Types of Dietary Fats?

Fats are essential to us because we need to consume them in a limited amount. The four types of dietary fats include the following:

• Polyunsaturated fat.

• Monounsaturated fat.

• Trans fat.

• Saturated fat.

These four fats differ in physical and chemical structures. Saturated and trans fats exhibit a solid state at room temperature, while mono and polyunsaturated fats remain in a liquid state at the same temperature.

1. Monounsaturated Fatty Acids (MUFA) And Polyunsaturated Fatty Acids (PUFA): MUFA and PUFA are considered beneficial. Because they are as low as LDL (low-density lipoprotein)

2. Trans Fat and Saturated Fat:

Whereas saturated and trans fats raise the low-density lipoproteins and are considered unhealthy. Regardless of the physical and chemical properties of trans and saturated fats, they provide nine calories for every gram consumed, much higher than the energy supplied per gram of carbohydrates or proteins.

What Are Other Effects of a Low Fat Diet?

An increasing body of evidence indicates that reducing or modifying serum cholesterol could be a potential approach to prevent atherosclerosis.

• Decreasing the fat intake is an effective way to lower serum cholesterol concentration.

• Hence, clinicians have widely advocated a low-fat diet for reducing their patients' cardiovascular morbidity or mortality.

• As per the NCEP (National Cholesterol Education Program) guidelines from ATP 3 (Adult Treatment Panel), it is recommended to limit the consumption of saturated fats to less than 7 percent of total daily calories and cholesterol to below 200 milligrams per day.

• The guidelines also recommend that polyunsaturated fats constitute up to 20% of calories.

What Are the Issues to Concern in Taking a Low-Fat Diet?

• There are more controversies and multiple issues of concern around the concept of a low-fat diet.

• The biggest concern with promoting the low-fat diet has been that manufacturing companies are tooting products labeled as low-fat diet products.

• When individuals substitute fat with significant quantities of refined carbohydrates, it elevates the risk of developing metabolic disorders and hypertriglyceridemia.

• A proposed theory suggests that refined carbohydrates may impair the cardio-protective functions of HDL (high-density lipoprotein) by altering its metabolic actions.

• Many studies report that a carbohydrate-rich diet is low in unsaturated fat, can harm lipoprotein risk factors, and increase cardiovascular risks.

What Is the Clinical Significance of a Low-Fat Diet?

In cardiovascular disease:

• Additionally, dietary cholesterol has garnered significant attention because of its direct link to blood cholesterol levels and the subsequent risks it poses for coronary artery disease.

• There is a direct relationship between fat intake and cardiovascular disease.

• The level of LDL particles serves as the most reliable predictor of cardiovascular disease.

• Recent studies show that in man, there is a reduction of total fat and saturated fatty acids from 36 percent and 12 percent of energy to 27 percent and 8 percent of energy, respectively, resulting in a substantial decline in the total and LDL Cholesterol.

In Cancers:

• Some epidemiological evidence demonstrates an association between dietary fat intake and cancers affecting breast, colon, prostate and lungs.

• Among all cancers, dietary fat intake directly links to breast cancer.

• Studies suggest that the positive effect of polyunsaturated fatty acids, especially omega-three fatty acids, is protective against the development of cancers, and high animal fat has the strongest positive correlation to developing cancers.

• A potential mechanism for the relationship between fat intake and prostate cancer includes an altered level of sex hormones.

• The mortality rate from colorectal cancer correlated with the consumption of animal fat.

• A potential mechanism for diet and colon cancer links is primarily related to bile acid secretion or intestinal metabolism.

Association With Obesity:

• Obesity is a chronic disease associated with diabetes mellitus, hypertension, dyslipidemia, fatty liver, and obstructive sleep apnea.

• It has multiple external and internal influences. Among many environmental impacts, dietary fat intake is the strongest association.

• The various epidemiological studies, including ecologic, cross-sectional, and prospective studies, Prove a relationship between diet consumption and body weight.

• Fat is an energy-dense food consumption to excess calorie ingestion compared to other foods.

• Many studies show that the obese population has a higher energy intake from fat than people with a healthy BMI (body mass index).

Examples of Low Fat Diet That They Can Include in Their Diet

1. Dairy Products:

Usually, dairy products are rich in fat, but manufacturers often offer lower-fat versions. These

Include the following:

• It is important to remember that not all fat types are unhealthful when considering a low-fat diet. The most important thing to remember when considering a low-fat diet is that not all fat types are unhealthful.

• These fats increase a person's low-density lipoprotein cholesterol, increasing their risk of heart disease and other complications.

• The nutritious foods which contain these foods are

• Salmon, avocado

• Almonds,

• Cashew

• A lower-fat diet incorporating a variety of fresh fruits, vegetables, whole grains, and lean proteins offers superior nutritional value compared to diets high in fat derived from processed and fast foods.
