Most studies have found that nuts and peanuts lower the levels of bad cholesterol, improves health and reduces mucosal blood arteries possibility of developing blood clots that can cause a fatal heart attack.
2. Benefits for heart health
Although the amount varies depending on the type, most fruits with woody shell contain at least one of these substances needed for heart health:
- Unsaturated fats – is not entirely clear why, but it is supposed that good fats from walnuts and peanuts composition, both monounsaturated and polyunsaturated fats help lower the bad cholesterol.
- Omega-3 fatty acids – walnuts and peanuts are rich in omega-3 fatty acids, a healthy form of fatty acids that seem to prevent the occurrence of dangerous heart rhythms that can trigger heart attacks. Omega-3 fatty acids are found in many types of fish, but walnuts and peanuts are some of the best sources.
- Fiber – all nuts and peanuts contain fiber that helps lower cholesterol, help installing satiety and plays a role in preventing diabetes.
- Vitamin E – helps to stop the growth of plaque in arteries, which can narrow and can cause chest pain, coronary artery disease or heart attack.
- Plant sterols – some fruit with woody shells contain plant sterols, substances that help lower cholesterol. Manufactured sterols are often added to margarine and orange juice for the benefits they have for health, but they are found naturally in all types of nuts.
- L-arginine – the walnuts and peanuts are a source of l-arginine, a substance that can help improve the health of arteries, making them more flexible and less prone to blood clots that can block the blood flow.
3. What amount of peanuts is considered healthy?
Fruits with woody shells contain much fat; 80% of their content is fat. Even though these are healthy fats, nuts are high in calories, so they should be eaten in moderation.
Ideally they should be used as a substitute for saturated fats such as those found in meat, eggs and dairy products. Instead of eating unhealthy saturated fats you should include nuts in your daily diet.
Will not exceed about 40 grams per day of almonds, peanuts, hazelnuts, pecans, walnuts, etc. They are designed to reduce the risk of developing heart disease only if they are part of a healthy diet.
4. Most beneficial nuts
Most fruits with woody shells appear to be generally healthy, although some are more beneficial than others. Walnuts are one of the fruits that have been studied extensively and found to be rich in high amounts of omega-3.
Almonds, macadamia nuts, hazelnuts and pecans seem to be the healthiest for the heart. Even peanuts (which technically are legumes) appear to be quite healthy. Coconut is a fruit from a technical standpoint, but is not part of the nuts and peanuts. It also does not provide benefits for cardiovascular health. Both core and oil of the coconut do not contain mono and polyunsaturated fats.
Other positive effects that can be obtained from including walnuts and peanuts in the diet include:
- Increase the level of serotonin in the body (substance that gives good general condition);
- Contribute to the fight against metabolic syndrome;
- Helps lower blood sugar levels and high blood pressure.
The positive effects of nuts may be canceled if they are covered with chocolate, sugar or salt.
